Question

I’m currently using Doctrine 1.2.2 with MySQL on the backend. When I attempt to retrieve a result set for more than one item using the record or lazy load hydration modes, only a single item shows up. However, when I use the array hydration mode, I see all of the results. Consistently, only the last item in the result set is retrieved.

Did I misunderstand the API? Is the model defined incorrectly (it was autogenerated). Shouldn’t it be this simple?

Right now, I’m firing up my debugger and I will be stepping through Doctrine’s source code.

// Model used:

<?php

/**
 * BaseEntryVote
 * 
 * This class has been auto-generated by the Doctrine ORM Framework
 * 
 * @property integer $contest_id
 * @property integer $vote_id
 * @property integer $entry_id

Answer 1

Thanks to the nice folks on the #doctrine irc channel, I have this working now.

The source of the problem was that I did not have auto-increment set on the primary key of the vote table. So, if you are having similar problems, make sure that whatever column that you choose to have as your primary key in your model also has the auto-increment bit set in the database schema.
