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 auto-creates database tables and 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.
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.
An short example:
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:
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:
<code type="php">
require_once('lib/Doctrine.php');
spl_autoload_register(array('Doctrine', 'autoload'));
class User extends Doctrine_Record {
public function setTableDefinition() {
User.php :
<code>
class User extends Doctrine_Record
{
public function setTableDefinition()
{
// set 'user' table columns, note that
// id column is always auto-created
$this->hasColumn('name','string',30);
$this->hasColumn('username','string',20);
$this->hasColumn('password','string',16);
$this->hasColumn('created','integer',11);
$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_once('lib/Doctrine.php');
require_once('User.php');
spl_autoload_register(array('Doctrine', 'autoload'));
$conn = Doctrine_Manager::connection('pgsql://user:pass@localhost/test');
$conn->export->exportClasses(array('User'));
</code>
We now have a user model that supports basic CRUD opperations!
