Question

Say I got two Controllers like this Table1sController, and Table2sController.
With corresponding models: Table1sModel, Table2sModel.

In the Table1sController, I got this:

$this->Table1sModel->action();

Say I want to access some data in Table2sModel.

How is it possible to do something like this in Table1sController?
I have tried this in Table1sController:

$this->Table2sModel->action();

But I received an error message like this:

Undefined property: Table1sController::$Table2sModel

There are a few ways to go here.

If your models have defined associations (hasMany, etc.), then you can access that model’s methods (assuming you’re in Model1Controller) with:

$this->Model1->Model2->method();

If there is no model association between the two models, but you want to be able to use the Model2’s methods, you can add an entry in the $uses attribute of model1Controller. See http://book.cakephp.org/2.0/en/controllers.html#components-helpers-and-uses

Finally, if it’s a transitory connection (you don’t want the overhead of loading other models every time, because you’re only rarely going to access model2), check out the manual’s section on creating / destroying associations on the fly, at http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html
