Symfony 1.3 Web Application Development

Overview of this book

With its flexible architecture, the Symfony framework allows you to build modern web applications and web services easily and rapidly. The MVC components separate the logic from the user interface and therefore make developing, changing, and testing your applications much faster. Using Symfony you can minimize repetitive coding tasks, optimize performance, and easily integrate with other libraries and frameworks. Although this framework contains with many powerful features, most developers do not exploit Symfony to its full potential. This book makes it easy to get started and produce a powerful and professional-looking web site utilizing the many features of Symfony. Taking you through a real-life application, it covers all major Symfony framework features without pushing you into too much theoretical detail, as well as throwing some light on the best practices for rapid application development. This book takes you through detailed examples as well as covering the foundations that you will need to get the most out of the Symfony framework. You will learn to shorten the development time of your complex applications and maintain them with ease. You will create several useful plug-ins and add them to your application and automate common tasks. The book also covers best practices and discussions on security and optimization. You will learn to utilize all major features of this framework by implementing them in your application. By the end, you should have a good understanding of the development features of Symfony (for Propel as well as Doctrine editions), and be able to deploy a high-performance web site quite easily.

You never want a user to see that your web site is broken or appears not to be working. This generally happens when you have to make certain kinds of updates to your site, for example, modifying the database. Therefore, through the CLI, you can disable an application as well as an environment by using the Symfony disable task. First, we must enable Symfony to check for a lock file. This file is created once we have disabled the applications. In our settings file located at apps/frontend/config/settings.yml, add the following:

     no_script_name:        on
     logging_enabled:       off
     check_lock:            on

Now, we can disable our application using the Symfony task, as follows:

>symfony project:disable frontend dev

Once you have executed this command, all the URLs are routed to the unavailable action in the Symfony's default module. The following screenshot shows the default unavailable page that is shown if we try to access our dev...
