Cakephp SQL Error: 1064:

Have a find call on a table called Attachment which is assiciated with another table called AddOn. I get a sql error. It seems to be looking for a field called display_field but this is not in the table. Why it is looking for it I do not know.

$previous = $this->AddOn->Attachment->find('first', array('conditions'=> array('model'=>'AddOn', 'foreign_key'=>$id)));

Error:

The SQL query being performed is: display

As you know, the SQL query you are looking for should start like: SELECT <something> FROM ...

This one clearly doesn't and that is what MySQL is trying to tell you.

Check you aren't calling a method called display() from any of your code:

$this->display(); // in models or behaviors
$this->Attachment->display(); // in controller, etc

CakePHP tends to do this when you call a missing method on a model.

A common culprit is thinking you have included a behavior by setting the model property $actAs when the correct property is actually called $actsAs.
