问题
I'm writing a plugin which includes a behavior that has a dependency on the ContainableBehavior. In my behavior, I'd like to tweak any query conditions in its beforeFind() callback, but I'm finding that ContainableBehavior::beforeFind() has already been executed so my changes of course are falling on deaf ears, so to speak.
The only solution, as far as I can tell, is to manually change the behavior execution order so that my behavior's beforeFind() method is called before ContainableBehavior::beforeFind(), but I'm having some trouble making that happen.
I don't want to make any assumptions about the apps that may use my plugin so I don't want to create an arbitrary dependency that defines how users have to configure any behaviors they're using. I'd like to just make the necessary adjustment on the fly where I need to make it. What I thought made the most sense is this:
In MyBehavior::setup(), I'm simply trying to detach and reattach the ContainableBehavior so that in the collection of behaviors attached to the parent model, it falls after MyBehavior:
# Assume that a condition checking existence is in place
$model->Behaviors->detach( 'Containable' );
$model->Behaviors->attach( 'Containable' );
If I then dump the list of attached behaviors, I get an array with the attached behaviors ordered the way I want them, but ContainableBehavior::beforeFind() still fires before MyBehavior::beforeFind().
Is there any way to force the execution order of behavior callbacks that isn't a total hack job or that doesn't impose an unrealistic dependency/standard on any apps that may deploy the plugin?
Thanks.
