+++ 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('path-to-doctrine/lib/Doctrine.php');
|
|
|
|
spl_autoload_register(array('Doctrine', 'autoload'));
|
|
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
|
|
Doctrine::generateModelsFromDb('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
|
|
*/
|
|
abstract class BaseFile extends Doctrine_Record
|
|

|
