Extending ORM classes in CakePHP 3

Question

I would like to extend Query class in order to create function customContain() available in every Table model. How should I do it?

Answer 1

I want to use that BleMethod() in all table models in cakephp. Where I have to add code of that function? Where I have to implements BleMethod?

Unlike Cake2 Cake3 does not feature an application level class like AppModel from where all other classes inherit from. So you have two options:

• Trait
• Behavior

The behavior can be loaded globally to all models by using the Model.initialize event. And then loading the behavior inside the events callback. Read these pages:

• Creating a behavior
• Event system
• Model / Table callbacks

But that's not what you want

customContain() indicates for me that you want to setup some contains very often. Well, use finders.

Finders can be combined:

$this->Table->find('foo')->find('myContains')->all();

Each custom find will add something to the query object. You can add your custom contains this way.
