Re: Trouble with using a condition on a related model

Dean,

CakePHP will not produce a join for hasMany and HABTM finds. As a
result, the fields of the associated table are not avaiable for the
query. There are a variety of techniques to get what you want.

There's the linkable behavior, ad-hoc join, and a method using
bindModel to bind the relationship as a hasOne to get CakePHP to do
the joins. These are discussed in the manual, on the bakery, and in
blogs.
