Relationship Between Database Tables In Cakephp

acceslist — Wed, 15 Apr 2009 09:16:56 +0000

Database relationship is hard to maintain even for a mid-sized PHP/MySQL application, particularly, when multiple levels of relationships are involved because complicated SQL queries are needed. CakePHP offers a simple yet powerful feature called ‘object relational mapping’ or ORM to handle database relationships with ease.In CakePHP, relations between the database tables are defined through association—a way to represent the database table relationship inside CakePHP. Once the associations are defined in models according to the table relationships, we are ready to use its wonderful functionalities. Using CakePHP’s ORM, we can save, retrieve, and delete related data into and from different database tables with simplicity, in a better way—no need to write complex SQL queries with multiple JOINs anymore!

In this article by Ahsanul Bari and Anupom Syam, we will have a deep look at various types of associations and their uses. In particular, the purpose of this article is to learn:

How to figure out association types from database table relations

How to define different types of associations in CakePHP models

How to utilize the association for fetching related model data

How to relate associated data while saving

There are basically 3 types of relationship that can take place between database tables:

one-to-one

one-to-many

many-to-many

The first two of them are simple as they don’t require any additional table to relate the tables in relationship. In this article, we will first see how to define associations in models for one-to-one and one-to-many relations. Then we will look at how to retrieve and delete related data from, and save data into, database tables using model associations for these simple associations.

Defining One-To-Many Relationship in Models

To see how to define a one-to-many relationship in models, we will think of a situation where we need to store information about some authors and their books and the relation between authors and books is one-to-many. This means an author can have multiple books but a book belongs to only one author (which is rather absurd, as in real life scenario a book can also have multiple authors). We are now going to define associations in models for this one-to-many relation, so that our models recognize their relations and can deal with them accordingly.

Time for Action: Defining One-To-Many Relation

Create a new database and put a fresh copy of CakePHP inside the web root. Name the database whatever you like but rename the cake folder to relationship. Configure the database in the new Cake installation.

Execute the following SQL statements in the database to create a table named authors,

Create a books table in our database by executing the following SQL commands:

Create the Author model using the following code (/app/models/authors.php):

Use the following code to create the Book model (/app/models/books.php):

Create a controller for the Author model with the following code: (/app/controllers/authors_controller.php):

Use the following code to create a controller for the Book model (/app/controllers/books_controller.php):We have created two tables: authors and books for storing author and book information.

A foreign-key named author_id is added to the books table to establish the one-to-many relation between authors and books. Through this foreign-key, an author is related to multiple books, as well as, a book is related to one single author.

By Cake convention, the name of a foreign-key should be underscored, singular name of target model, suffixed with _id.

Once the database tables are created and relations are established between them, we can define associations in models. In both of the model classes, Author and Book, we defined associations to represent the one-to-many relationship between the corresponding two tables. CakePHP provides two types of association: hasMany and belongsTo to define one-to-many relations in models.

These associations are very appropriately named:

As an author ‘has many’ books, Author model should have hasMany association to represent its relation with the Book model.

As a book ‘belongs to’ one author, Book model should have belongsTo association to denote its relation with the Author model.

In the Author model, an association attribute $hasMany is defined with the value Book to inform the model that every author can be related to many books. We also added a $belongsTo attribute in the Book model and set its value to Author to let the Book model know that every book is related to only one author.

After defining the associations, two controllers were created for both of these models with scaffolding to see how the associations are working.

MVC (Model-View-Controller) Approach Cakephp

acceslist — Thu, 15 Jan 2009 09:04:57 +0000

CakePHP follows the MVC software design pattern. Programming using MVC separates your application into three main parts:

The Model represents the application data

The View renders a presentation of model data

The Controller handles and routes requests made by the clien

Why use MVC? Because it is a tried and true software design pattern that turns an application into a maintainable, modular, rapidly developed package. Crafting application tasks into separate models, views, and controllers makes your application very light on its feet. New features are easily added, and new faces on old features are a snap. The modular and separate design also allows developers and designers to work simultaneously, including the ability to rapidly prototype. Separation also allows developers to make changes in one part of the application without affecting others.

If you’ve never built an application this way, it takes some time getting used to, but we’re confident that once you’ve built your first application using CakePHP, you won’t want to do it any other way.

The CakePHP framework provides a robust base for your application. It can handle every aspect, from the user’s initial request all the way to the final rendering of a web page. And since the framework follows the principles of MVC, it allows you to easily customize and extend most aspects of your application.

The framework also provides a basic organizational structure, from filenames to database table names, keeping your entire application consistent and logical. This concept is simple but powerful. Follow the conventions and you’ll always know exactly where things are and how they’re organized.

Computer Virtualization With VMWARE

acceslist — Thu, 12 Jun 2008 05:28:49 +0000

Virtualization essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. Virtual servers and virtual desktops let you host multiple operating systems and multiple applications locally and in remote locations, freeing you from physical and geographical limitations. In addition to energy savings and lower capital expenses due to more efficient use of your hardware resources, you get high availability of resources, better desktop management, increased security, and improved disaster recovery processes when you build a virtual infrastructure.

What is Virtualization?

Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute.

Today’s powerful x86 computer hardware was originally designed to run only a single operating system and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same computer at the same time, increasing the utilization and flexibility of hardware.

Virtualization is a technology that can benefit anyone who uses a computer, from IT professionals and Mac enthusiasts to commercial businesses and government organizations. Join the millions of people around the world who use virtualization to save time, money and energy while achieving more with the computer hardware they already own.

How Does Virtualization Work?

In essence, virtualization lets you transform hardware into software. Use software such as VMware ESX to transform or “virtualize” the hardware resources of an x86-based computer—including the CPU, RAM, hard disk and network controller—to create a fully functional v irtual machine that can run its own operating system and applications just like a “real” computer.

Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer.

The VMware Approach to Virtualization

The VMware approach to virtualization inserts a thin layer of software directly on the computer hardware or on a host operating system. This software layer creates virtual machines and contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently so that multiple operating systems can run concurrently on a single physical computer without even knowing it.

However, virtualizing a single physical computer is just the beginning. VMware offers a robust virtualization platform that can scale across hundreds of interconnected physical computers and storage devices to form an entire virtual infrastructure.

Planning Wireless Network

acceslist — Wed, 11 Jun 2008 02:44:53 +0000

Standard
The Wireless Access Point utilizes the 802.11b and the 802.11g standards. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps (108Mbps in Super G mode) within the 2.4GHz band, utilizing OFDM technology. This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format you’re your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of cross talk (interference) in signal transmissions. The AP will automatically sense the best possible connection speed to ensure the greatest speed and range possible. 802.11g offers the most advanced network security features available today, including: WPA, TKIP, AES and Pre-Shared Key mode.

Network Topology
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another to form an ad-hoc network. The wireless adapters also provide users access to a wired network when using an access point or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless router. An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data within a network, the effective transmission range in an infrastructure network may be doubled.

Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your wireless PC within your network and the access points will pick up the wireless PC’s signal, providing that they both share the same channel and SSID. Before enabling you consider roaming, choose a feasible radio channel and optimum access point position. Proper access point positioning combined with a clear radio signal will greatly enhance performance.
Network Layout
The AP Access Point has been designed for use with 802.11g and 802.11b products. With 802.11g products communicating with the 802.11b standard, products using these standards can communicate with each other. The Access point is compatible with 802.11g and 802.11b adapters, such at the PC Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB connectivity. These wireless products can also communicate with a 802.11g or 802.11b wireless Print Server. When you wish to connect your wired network with your wireless network, the Access Point’s network port can be used to connect to any of switches or routers.

Installation Considerations
The AP lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:
􀁺 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
􀁺 Keep the number of walls and ceilings between the AP and other network devices to a minimum – each wall or ceiling can reduce your AP’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.
􀁺 Be aware of the direct line between network devices. A wall that is 1.5 feet thick(0.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.
􀁺 Building materials can impede the wireless signal – a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials.

Cisco BGP Config Example for Customers, Transit and Peers

acceslist — Tue, 10 Jun 2008 02:24:46 +0000

Due to the ease of configuring bgp, it is easy to leave out critical steps that will result in some unintended consequences. There are a number of cases that exist persistently in the routing tables where some small network is actually connecting two “larger” networks together for some routes/prefixes for various reasons.
As a result of this, and the ease of these errors/mistakes, we wanted to provide a few simple examples that would ease most networks configuration needs and provide a common reference.

These examples cover a few basic bgp related topics, including:

route-maps

prefix-lists

example uses of communities

local-preferenceSome requirements for these examples, make sure the following are configured on your router(s):

Router(config)#ip bgp-community new-format Router(config)#router bgp xxx Router(config-router)#bgp always-compare-med Router(config-router)#bgp bestpath med confed Router(config-router)#bgp log-neighbor-changes Router(config-router)#no auto-summary Router(config-router)#no synchronization

This enables the usage of bgp communities in your configuration files in the asn:xxx format which ease their readability as compared to a “really big” number. The BGP specific config(s) will help in debugging, as well as provide for a more normalized and deterministic bgp decision process. It should be noted that these changes should perhaps not be made during any mission-critical time of day unless you are prepared to find the console quickly .

These examples also assume a simple model, that i’ve placed in the following table. The basic premise is that you want to send traffic to your customers before you send it to peers before you send it to your transit(s). This means send it to those that pay you to the increasing cost of those places that bill you. While you may think that bgp will automatically do this for you, it may not do it exactly as you expect. It’s generally much better to configure this explicitly.

Type Local Pref Community

Transit 80 xxx:180

Peer 100 xxx:200

Customer 120 xxx:220

(xxx in this case would be your asn. If your ASN were 701, that would be 701:220 for your customer routes.)

Now for the more specific BGP configs, you will want to start with your customer links and move towards your peers and transit links. This will keep their local-prefernece higher than the default (100) and start to tag their routes with the community that says you want to send it to your upstreams/peers.

router bgp xxx neighbor 1.2.3.4 remote-as 267 neighbor 1.2.3.4 prefix-list AS267-in in neighbor 1.2.3.4 route-map customer-in in neighbor 1.2.3.4 route-map customer-out out ! route-map customer-in set community xxx:220 set local-preference 120 ! route-map customer-out match community cust-out ! ip community-list expanded cust-out permit xxx:220 ip community-list expanded cust-out permit xxx:200 ip community-list expanded cust-out permit xxx:180 ! ip prefix-list AS267-in seq 5 permit 204.42.0.0/16 ip prefix-list AS267-in seq 10 deny 0.0.0.0/0 !

So, this does a few things for you. First, it only sends them prefixes that match your transit, peer and customer routes that have been tagged with these communities. It also sets their routes with the customer (xxx:220) community, and sets the prefernece internally to 120. This will also go to your other internal bgp peers (if any) within your ibgp mesh. You want to populate the AS267-in prefix-list with those routes that you want to accept from your customers. You don’t want to accept all routes, as they may have misconfigured their router to send you some of their peer or transit routes that they are not expecting to go via this link. I listed an example prefix above, with an explicit deny at the end.Now that you’ve tagged your customer routes, you may want or need to tag your itnernal routes as well with the appropriate community. The best way to do this is to have a route-map that matches against a prefix-list that contains your aggregate routes. This is currently left as an excersise for the reader to implement, as there are numerous ways to announce, including connected (Null0) routes, aggregate and other ways to originate the routes.

transit/peer configs

Tagging your transit and peer routes is perhaps the most important thing to do. You don’t want to leak one transit/peer to another (unless you have some very specific needs).

Following the above configuration example for a customer routes, the natural evolution is the following configuration example:

router bgp xxx neighbor 1.2.3.4 remote-as 267 neighbor 1.2.3.4 route-map peer-in in neighbor 1.2.3.4 route-map peer-out out ! route-map peer-in set community xxx:200 set local-preference 100 ! route-map peer-out match community peer-out ! ip community-list expanded peer-out permit xxx:220 !

This matches just routes that were tagged with the “220″ community, which would be your internal+customer routes. You could tag your internal routes with some additional new community you create to make them show up differently from your “customer” prefixes. If so, add those to your peer-out community-list.Transit routes generally are identical to peer routes, but you may want to do soemthing different with them in the future so it’s ideal to have a different route-map and community-list for manipulating those announcements. If you’re trying to go easy on this all, here is the cut+paste that may help you out:

router bgp xxx neighbor 1.2.3.4 remote-as 267 neighbor 1.2.3.4 route-map transit-in in neighbor 1.2.3.4 route-map transit-out out ! route-map transit-in set community xxx:180 set local-preference 80 ! route-map transit-out match community transit-out ! ip community-list expanded transit-out permit xxx:220 !

Apache Web Server

acceslist — Mon, 09 Jun 2008 06:53:33 +0000

What Is Apache Web Server
The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards. Apache has been the most popular web server on the Internet since April 1996.

The Apache HTTP Server Project is proud to announce the release of version 2.2.8 of the Apache HTTP Server (“Apache”). This version is principally a security and bugfix release.
This version of Apache is a major release and the start of a new stable branch, and represents the best available version of Apache HTTP Server. New features include Smart Filtering, Improved Caching, AJP Proxy, Proxy Load Balancing, Graceful Shutdown support, Large File Support, the Event MPM, and refactored Authentication/Authorization.

Installing Apache
1. First you must download source from http://httpd.apache.org/docs/2.2/install.html#download
2. Exstract Source
Extracting the source from the Apache HTTPd tarball is a simple matter of uncompressing, and then untarring:

$ gzip -d httpd-NN.tar.gz
$ tar xvf httpd-NN.tar

This will create a new directory under the current directory containing the source code for the distribution. You should cd into that directory before proceeding with compiling the server.

3. Configure Source Tree

The next step is to configure the Apache HTTPd source tree for your particular platform and personal requirements. This is done using the script configure included in the root directory of the distribution. (Developers downloading an unreleased version of the Apache HTTPd source tree will need to have autoconf and libtool installed and will need to run buildconf before proceeding with the next steps. This is not necessary for official releases.)

To configure the source tree using all the default options, simply type ./configure. To change the default options, configure accepts a variety of variables and command line options.

The most important option is the location –prefix where the Apache HTTP Server is to be installed later, because Apache HTTPd has to be configured for this location to work correctly. More fine-tuned control of the location of files is possible with additional configure options.

Also at this point, you can specify which features you want included in Apache HTTPd by enabling and disabling modules. The Apache HTTP Server comes with a Base set of modules included by default. Other modules are enabled using the –enable-module option, where module is the name of the module with the mod_ string removed and with any underscore converted to a dash. You can also choose to compile modules as shared objects (DSOs) — which can be loaded or unloaded at runtime — by using the option –enable-module=shared. Similarly, you can disable Base modules with the –disable-module option. Be careful when using these options, since configure cannot warn you if the module you specify does not exist; it will simply ignore the option.

In addition, it is sometimes necessary to provide the configure script with extra information about the location of your compiler, libraries, or header files. This is done by passing either environment variables or command line options to configure. For more information, see the configure manual page.

For a short impression of what possibilities you have, here is a typical example which compiles Apache for the installation tree /sw/pkg/apache with a particular compiler and flags plus the two additional modules mod_rewrite and mod_speling for later loading through the DSO mechanism:

$ CC=”pgcc” CFLAGS=”-O2″ \
./configure –prefix=/sw/pkg/apache \
–enable-rewrite=shared \
–enable-speling=shared

When configure is run it will take several minutes to test for the availability of features on your system and build Makefiles which will later be used to compile the server.

Details on all the different configure options are available on the configure manual page.

4. Build
Now you can build the various parts which form the Apache HTTPd package by simply running the command:

$ make

Please be patient here, since a base configuration takes several minutes to compile and the time will vary widely depending on your hardware and the number of modules that you have enabled.

5. Install
Now it’s time to install the package under the configured installation PREFIX (see –prefix option above) by running:

$ make install

If you are upgrading, the installation will not overwrite your configuration files or documents.

6. Customize
Next, you can customize your Apache HTTP Server by editing the configuration files under PREFIX/conf/.

$ vi PREFIX/conf/httpd.conf

Have a look at the Apache HTTP Server manual under docs/manual/ or consult http://httpd.apache.org/docs/2.2/ for the most recent version of this manual and a complete reference of available configuration directives.

7. Test Instalation
Now you can start your Apache HTTP Server by immediately running:

$ PREFIX/bin/apachectl -k start

and then you should be able to request your first document via URL http://localhost/. The web page you see is located under the DocumentRoot, which will usually be PREFIX/htdocs/. Then stop the server again by running:

$ PREFIX/bin/apachectl -k stop

User Manager Mikrotik For PPOE

acceslist — Mon, 09 Jun 2008 06:26:09 +0000

Introduction

User Manager can be used as a remote authentication, authorization and accounting server for PPP clients.

Since 2.9.35 PAP,CHAP, MS-CHAPv1 and MS-CHAPv2 protocols are supported by the User Manager.

Let us consider the following configuration steps for PPP and User Manager routers.

PPP configuration

We consider PPPoE server <-> PPPoE client configuration example, where the PPPoE server uses a remote User Manager database for PPPoE client authentication, authorization and accounting. Both PPPoE server and PPPoE client are MikroTik routers, any other PPPoE client might be used instead.

[edit] PPP server configuration

First, add the PPPoE server to the local interface, :

/ interface pppoe-server server add interface=ether1 service-name=MikroTik one-session-per-host=yes disabled=no

Specify the use of User Manager for PPPoE clients:

/ ppp aaa set use-radius=yes

Set IP address of the PPPoE server, IP address might not be assigned to the interface of PPPoE server. Moreover static IP address or DHCP should not be used on the same interfaces as the PPPoE server for security reasons.

/ ppp profile set default local-address=192.168.0.1

Add radius client to consult User Manager for PPP service.

/ radius add service=ppp address=y.y.y.y secret=123456

‘secret’ is equal to User Manager router secret. ‘y.y.y.y’ is the User Manager router address.

Note, first the local PPP database is consulted, then the User Manager database.

[edit] PPP client configuration

Add PPPoE client to the interface

/ interface pppoe-client add interface=ether1 user=MikroTik password=MikroTik service-name=MikroTik disabled=no

[edit] User Manager configuration

First, you need to download and install User Manager package;

Create User Manager subscriber;

/ tool user-manager customer add login="MikroTik" password="qwerty" permissions=owner

Add PPP server information to router list,

/ tool user-manager router add subscriber=MikroTik ip-address=x.x.x.x shared-secret=123456

‘x.x.x.x’ is the address of the PPPoE-server router, ‘shared-secret’ should match on both User Manager and PPPoE-server routers.

Add PPPoE client information,

/ tool user-manager user add username=demo password=demo subscriber=MikroTik ip-address=192.168.0.2

Let us verify, that PPPoE client is connected and using User Manager for authentication, authorization and accounting. First we monitor if PPPoE client is connected, then we verify that User Manager was used. The first command is executed on PPPoE client router, second on PPPoE server:

/ interface pppoe-client monitor pppoe-out1 status: "connected" uptime: 12h2m29s idle-time: 12h2m17s service-name: "MikroTik" ac-name: "MikroTik" ac-mac: 00:0C:42:05:54:8F mtu: 1480 mru: 1480

/ ppp active> print Flags: R - radius # NAME SERVICE CALLER-ID ADDRESS UPTIME ENCODING 0 R MikroTik pppoe 00:0C:42:05:54:6E 192.168.0.2 12h1m48s

User Manager Mikrotik

acceslist — Mon, 09 Jun 2008 06:23:00 +0000

User manager is a management system that can be used for:
* HotSpot users;
* PPP (PPtP/PPPoE) users;
* DHCP users;
* Wireless users;
* RouterOS users.

Requirements
* You should have the same version for RouterOS and the User Manager package.
* The MikroTik User Manager works on x86, MIPS and PowerPC processor based routers.
* The router should have at least 32MB RAM and 2MB free HDD space.

User Manager/Hotspot Example

To make this setup, you should have running Hotspot server on the router. Let us consider configuration steps for HotSpot and User Manager routers, in order to use User Manager for HotSpot users.
[edit] HotSpot configuration

* Set HotSpot to use User Manager for HotSpot server users,

/ ip hotspot profile set hsprof1 use-radius=yes

* Add radius client to consult User Manager for HotSpot service.

/ radius add service=hotspot address=y.y.y.y secret=123456

‘secret’ is equal to User Manager router secret. ‘y.y.y.y’ is the User Manager router address. By default this is 127.0.0.1. If using a remotely located Router (perhaps via a VPN) then the IP address entered is the IP address of that remote Router. The router could be a Radius Server, or another ROS with User Manager installed.

* Note, first local HotSpot database is consulted, then User Manager database.

It means that if you have configuration in ‘/ ip hotspot user print’, users will be able to authenticate in HotSpot using these data. Delete users configuration from ‘/ ip hotspot print’ to stop using local HotSpot database for authentication. To move batch of local HotSpot users to the User Manager database use export/import . Use text editor program to create appropriate file to import local users to the User Manager database.

User Manager configuration

* First, you need to download and install User Manager package;
* Create User Manager subscriber;

/ tool user-manager customer add login=”MikroTik” password=”qwerty” permissions=owner

* Add HotSpot router information to router list,

/ tool user-manager router add subscriber=MikroTik ip-address=x.x.x.x shared-secret=123456

‘x.x.x.x’ is the address of the HotSpot router, ‘shared-secret’ should match on both User Manager and HotSpot routers. Adding ‘x.x.x.x’ as a router allows Radius requests from ‘x.x.x.x’ to be passed to the Radius Server built into User Manager. Therefore if you have any remote ROS Hotspots that require access to this Radius Server, then all their IP addresses must be added to this list.

* Add HotSpot user information, it is equal to ‘ip hotspot user’ when local HotSpot is used for clients

/ tool user-manager user add username=demo password=demo subscriber=MikroTik

We discuss only basic configuration example, detailed information about ‘user’ menu configuration.

* You can use User Manager web interface after first subscriber created.

* To make sure, that client is using User Manager for AAA,

/ ip hotspot active print
Flags: R – radius, B – blocked
# USER ADDRESS UPTIME SESSION-TIME-LEFT IDLE-TIMEOUT
0 R 00:01:29:2… 192.168.100.2 1m29s

‘R’ means that client uses User Manager server for AAA services.
