+++ Introduction
A common case when looking for ORM tools like Doctrine is that the database and the code that access it is growing large/complex. A more substantial tool is needed then manual SQL code.
Doctrine has support for generating Doctrine_Record classes from your existing database. There is no need for you to manually write all the Doctrine_Record classes for your domain model.
+++ Making the first import
Let's consider we have a mysql database called test with a single table called 'file'.
The file table has been created with the following sql statement:
<code type="sql">
CREATE TABLE file (
id INT UNSIGNED AUTO_INCREMENT NOT NULL,
name VARCHAR(150),
size BIGINT,
modified BIGINT,
type VARCHAR(10),
content TEXT,
path TEXT,
PRIMARY KEY(id))
</code>
Now we would like to convert it into Doctrine record class. It can be achieved easily with the following code snippet:
<code type="php">
require_once('lib/Doctrine.php');
spl_autoload_register(array('Doctrine', 'autoload'));
$conn = Doctrine_Manager::connection('mysql://root:dc34@localhost/test');
// import method takes one parameter: the import directory (the directory where
// the generated record files will be put in
$conn->import->import('myrecords');
</code>
That's it! Now there should be a file called File.php in your myrecords directory. The file should look like:
<code type="php">
/**
* This class has been auto-generated by the Doctrine ORM Framework
* Created: Saturday 10th of February 2007 01:03:15 PM
*/
class File extends Doctrine_Record
{
public function setTableDefinition()
{
$this->hasColumn('id', 'integer', 4, array('notnull' => true,
'primary' => true,
'unsigned' > true,
'autoincrement' => true));
$this->hasColumn('name', 'string', 150);
$this->hasColumn('size', 'integer', 8);
$this->hasColumn('modified', 'integer', 8);
$this->hasColumn('type', 'string', 10);
$this->hasColumn('content', 'string', null);
$this->hasColumn('path', 'string', null);
}
public function setUp()
{
}
}
</code>
