Well the strange thing is that "findAfter" is not being called in a
deeply nested association. Also functions calls to the model do get
triggered but I was hoping that the model would contain data retrieved
from the database (instead of just an empty Model "shell").
Here is a good example to illustrate:
Post hasMany Comments
Comment hasOne User
class PostsController extends AppController {
...
function view($id=NULL){
$this->Post->id = $id;
$this->Post->expects(array('PostImage',
'Comment','Comment.User'));
$this->Post->recursive = 2;
$this->set('post', $this->Post->read());
// here I would like to call a function that is associated
with the Users (either in the User Model or UsersController)
// afterFind never gets triggered for the User model (no idea
why...) but it is in view's print_r of the $post
// this calls the model function but the object does not have
any data that was pulled from the db
$this->Post->Comment->User->foo(); // Outputs 'hello my name
is: '
// my noob idea would be that you would have to access it from
the array of Comments like:
foreach ($this->Post->Comment as $comment){
$comment->User->foo();
}
// produces:
// Notice: Trying to get property of non-object
// Fatal error: Call to a member function callMe()
}
} // end Post
class User extends AppModel {
...
function afterFind($result){
print('This never gets called even though there is User data
in the Post's view output');
return $result;
}
function foo(){
print('Hello my name is: ' . $this->User->name);
}
...
}
Thanks for any help with trying to grasp Cake's object creation &
accessing scope.
