Kohana在foo类中使View :: factory（'/ foo / bar'）命中

My issue is that Kohana only renders the view. When I

View::factory('/foo/bar') in Controller_Other, it doesn't hit Controller_Foo first. I want it to hit the controller, then render the view.

class Controller_Other extends Controller_Template {
    public $template = 'main';
    public function action_index() {
        $this->template->body = View::factory('/foo/bar');
    }
}

How would I get it to run through the controller first:

class Controller_Foo extends Controller_Template {
    public function action_bar() {
        $this->myVar = 'foo';
    }
}

so that in the view, $myVar is always set in views/foo/bar.php when I call it from some other View::factory()?

Edit:

there must be a cleaner way than forcing action_bar to render its own view to string then going:

$foo = new Controller_Foo($this->request, $this->response);
$this->template->body = $foo->action_bar();

I'm not sure what you're doing - want to bind global view variable or do an internal request. Anyway, here are the examples for both cases:

bind global view variable

class Controller_Other extends Controller_Template {
    public $template = 'main';

    public function action_index() {
      View::bind_global('myVar', 'foo'); 
      //binds value by reference, this value will be available in all views. Also you can use View::set_global();

      $this->template->body = View::factory('/foo/bar');
    }

}

do an internal request

this is 'foo/bar' action

class Controller_Foo extends Controller_Template {

     public function action_bar() {
        $myVar = 'foo';
        $this->template->body = View::factory('/foo/bar', array('myVar' => $myVar);
     }
}



class Controller_Other extends Controller_Template {
    public $template = 'main';
    public function action_index() {
         $this->template->body = Request::factory('foo/bar')->execute()->body();
         //by doing this you have called 'foo/bar' action and put all its output to curent requests template body
    }
}

You should always pass $myVar variable to view before render it like

public function action_index() {
    $this->template->body = View::factory('/foo/bar')->set('myVar', 'foo');
}

In other controller you should set it again because View is just a temlate. If you plan to use the same view in different places of script you can assign View instance to some variable and use it somewhere like:

public function action_index() {
    $this->view = View::factory('/foo/bar')->set('myVar', 'foo');

    $this->template->body = $this->view ;
}

public function action_bar() {
    $this->template->head = $this->view ;
}
