Have been looking for way to sort foreign key records in Symfony 1.4 for few days. I’ve a staff table with a foreign key to comments. Whenever i call the StaffTable->getComments() the records return is not in alphabetical order. Finally i found some helpful tips from a forum (sorry i lost the forum url), and i manage to sort foreign key record with just a line of code. 🙂

To sort foreign key record in Symfony 1.4, follow the steps below:-

• Open the file lib/model/doctrine/base/BaseStaff.class.php and look for the function name ‘setUp‘ and look for this:-
  
  $this->hasMany('Comment', array( 'local' => 'staff_id', 'foreign' => 'comment_id', 'onDelete' => 'setnull'));

  1 2 3 4

  $this->hasMany('Comment', array(          'local' => 'staff_id',          'foreign' => 'comment_id',          'onDelete' => 'setnull'));

  
  Copy it and follow the next step.
• go to lib/model/doctrine/Staff.class.php
• Create a function as below:-
  
  public function setUp() { parent::setUp(); $this->hasMany('Comment', array( 'local' => 'staff_id', 'foreign' => 'comment_id', 'orderBy' => 'created_at', 'onDelete' => 'setnull'));)); }

  1 2 3 4 5 6 7 8

  public function setUp() {     parent::setUp();     $this->hasMany('Comment', array( 'local' => 'staff_id', 'foreign' => 'comment_id', 'orderBy' => 'created_at', 'onDelete' => 'setnull'));));         }

• Now refresh the page and you should see your record being sorted according to created_at time
