Doctrine_Record is the basic component of every doctrine-based project. There should be atleast one Doctrine_Record for each of your database tables. Doctrine_Record follows the [http://www.martinfowler.com/eaaCatalog/activeRecord.html Active Record pattern]
|
|
|
|
Doctrine always adds a primary key column named 'id' to tables that doesn't have any primary keys specified. Only thing you need to for creating database tables is defining a class which extends Doctrine_Record and setting a setTableDefinition method with hasColumn() method calls and by exporting those classes.
|
|
|
|
Lets say we want to create a database table called 'user' with columns id(primary key), name, username, password and created. Provided that you have already installed Doctrine these few lines of code are all you need:
|
|
|
|
User.php :
|
|
<code type="php">
|
|
class User extends Doctrine_Record
|
|
{
|
|
public function setTableDefinition()
|
|
{
|
|
// set 'user' table columns, note that
|
|
// id column is auto-created as no primary key is specified
|
|
|
|
$this->hasColumn('name', 'string',30);
|
|
$this->hasColumn('username', 'string',20);
|
|
$this->hasColumn('password', 'string',16);
|
|
$this->hasColumn('created', 'integer',11);
|
|
}
|
|
}
|
|
</code>
|
|
|
|
For exporting the user class into database we need a simple build script:
|
|
|
|
<code type="php">
|
|
//require the base Doctrine class
|
|
require_once('path-to-doctrine/lib/Doctrine.php');
|
|
|
|
//register the autoloader
|
|
spl_autoload_register(array('Doctrine', 'autoload'));
|
|
|
|
require_once('User.php');
|
|
|
|
//set up a connection
|
|
Doctrine_Manager::connection('mysql://user:pass@localhost/test');
|
|
|
|
//export the classes
|
|
Doctrine::createTablesFromArray(array('User'));
|
|
</code>
|
|
We now have a user model that supports basic CRUD opperations!
