Doctrine Default Primary Key Problem (Again)
- by 01010011
Hi,
Should I change all of my uniquely-named MySQL database primary keys to 'id' to avoid getting errors related to Doctrine's default primary key set in the plugin 'doctrine_pi.php'?
To further elaborate, I am getting the following reoccurring error, this time after trying to login to my login page:
SQLSTATE[42S22]: Column not found:
1054 Unknown column 'u.book_id' in
'field list'' in...
I suspect the problem resides at a MySQL table used for my login, of which has a primary key called
id
Marc B originally solved an identical problem for me in this post
http://stackoverflow.com/questions/2702229/doctrine-codeigniter-mysql-crud-errors
when I had the same problem with a different table within the same database. Following his suggestion, I changed the default primary key located at
system/application/plugins/doctrine_pi.php
from 'id' to 'book_id':
<?php
// system/application/plugins/doctrine_pi.php
...
// set the default primary key to be named 'id', integer, 4 bytes
Doctrine_Manager::getInstance()->setAttribute(
Doctrine::ATTR_DEFAULT_IDENTIFIER_OPTIONS,
array('name' => 'book_id', 'type' => 'integer', 'length' => 4));
and that solved my previous problem. However, my login page stopped working.
So what is the safe thing to do? Change all of my primary keys to 'id' (will that solve the problem without causing some other problem I am not aware of). Or should I add some lines of code in doctrine_pi.php?
