为什么Doctrine ORM不会为我的一对多模型创建SQL查询？

Question

I know this has to have an easy answer, but I cannot figure it out. After tears, I am hoping someone here can help.

Here is my YML model:

Identity:
  columns:
    id:
      type:           integer(10)
      primary:        true
      autoincrement:  true
    username:
      type:           string(255)

Profile:
  columns:
    id:
      type:           integer(10)
      primary:        true
      autoincrement:  true
    identity_id:
      type:           integer(10)
    profiletype_id:
      type:           integer(10)
    name:
      type:           string(255)
  relations:
    Identity:
      local:          identity_id
      foreign:        id
      class:          Identity
      foreignAlias:   Profiles
    Profiletype:
      local:          profiletype_id
      foreign:        id
      class:          Profiletype
      foreignAlias:   Profiles

Profiletype:
  columns:
    id:
      type:           integer(10)
      primary:        true
      autoincrement:  true
    type:
      type:           string(255)

As you can see, 3 linked tables are generated:

Identity
- can have multiple Profiles

Profile
- has one Identity
- has one Profiletype

Profiletype
- can have multiple Profiles

Now, In my code, I can perform queries on the generated models for Identity and Profiletype.

For example:

        $q = Doctrine_Query::create()
          ->select('i.*')
          ->from('Identity i');
        echo $q->getSqlQuery();

will work and produce:

SELECT i.id AS i__id, i.username AS i__username FROM identity i

However, when I go to run any query on the Profile table, it will not work. Even a simple query such as

        $q = Doctrine_Query::create()
          ->select('p.*')
          ->from('Profile p');
        echo $q->getSqlQuery();

fails. I have tried changing the class name in the FROM to 'Profiles' instead of 'Profile'. Still nothing.

Any ideas on what I'm doing wrong.

After changing every possible variable and tracing through my model line-by-line, I came to an embarrassing discovery:

The controller I was calling the Doctrine Query from was called profile.php.

profile.php

<?php
class Profile extends Controller {

    function Profile()     {
        parent::Controller();
    }

    function index()     {
        $q = Doctrine_Query::create()
            ->from('Profile');
        echo $q->getSqlQuery();
    }

}

Ass soon as I named the controller something else other than 'profile', it all suddenly worked. Eg, naming it to docile.php:

docile.php

<?php
class Docile extends Controller {

    function Docile()     {
        parent::Controller();
    }

    function index()     {
        $q = Doctrine_Query::create()
            ->from('Profile');
        echo $q->getSqlQuery();
    }

}

'Profile' does not appear to be a reserved word in CodeIgniter ( link text ). It does appear, however, that you cannot call a doctrine 'table class' from a controller class of the same name.

Thanks for your input guys. Hope this saves someone else similar hassles.
