In symfony, applications sharing the same data model are regrouped into projects. For most projects, you will have two different applications: a frontend and a backend.
Project Creation
From the sfproject/ directory, run the symfony generate:project task to
actually create the symfony project:
$ php lib/vendor/symfony/data/bin/symfony generate:project PROJECT_NAME
On Windows:
c:\> php lib\vendor\symfony\data\bin\symfony generate:project PROJECT_NAME
The generate:project task generates the default structure of directories and
files needed for a symfony project:
| Directory | Description |
|---|---|
apps/ |
Hosts all project applications |
cache/ |
The files cached by the framework |
config/ |
The project configuration files |
lib/ |
The project libraries and classes |
log/ |
The framework log files |
plugins/ |
The installed plugins |
test/ |
The unit and functional test files |
web/ |
The web root directory (see below) |
note
Why does symfony generate so many files? One of the main benefits of using a full-stack framework is to standardize your developments. Thanks to symfony's default structure of files and directories, any developer with some symfony knowledge can take over the maintenance of any symfony project. In a matter of minutes, he will be able to dive into the code, fix bugs, and add new features.
The generate:project task has also created a symfony shortcut in the
project root directory to shorten the number of characters you have to write
when running a task.
So, from now on, instead of using the fully qualified path to the symfony
program, you can use the symfony shortcut.
Configuring the Database
The symfony framework supports all PDO-supported databases (MySQL, PostgreSQL, SQLite, Oracle, MSSQL, ...) out of the box. On top of PDO, symfony comes bundled with two ORM tools: Propel and Doctrine.
When creating a new project, Doctrine is enabled by default. Configuring the
database used by Doctrine is as simple as using the configure:database task:
$ php symfony configure:database "mysql:host=localhost;dbname=dbname" root mYsEcret
The configure:database task takes three arguments: the
PDO DSN, the username, and
the password to access the database. If you don't need a password to access
your database on the development server, just omit the third argument.
tip
If you want to use Propel instead of Doctrine, add --orm=Propel when creating
the project with the generate:project task. And if you don't want to use an
ORM, just pass --orm=none.
Application Creation
Now, create the frontend application by running the generate:app task:
$ php symfony generate:app frontend
tip
Because the symfony shortcut file is executable, Unix users can replace all
occurrences of 'php symfony' by './symfony' from now on.
On Windows you can copy the 'symfony.bat' file to your project and use
'symfony' instead of 'php symfony':
c:\> copy lib\vendor\symfony\data\bin\symfony.bat .
Based on the application name given as an argument, the generate:app task
creates the default directory structure needed for the application under the
apps/frontend/ directory:
| Directory | Description |
|---|---|
config/ |
The application configuration files |
lib/ |
The application libraries and classes |
modules/ |
The application code (MVC) |
templates/ |
The global template files |
Directory Structure Rights
Before trying to access your newly created project, you need to set the write
permissions on the cache/ and log/ directories to the appropriate levels,
so that your web server can write to them:
$ chmod 777 cache/ log/
