Including multiple models to view or controller from different controllers

Question

I am developing a "Customer Dashboard" component in Joomla 3.2.
I need to include multiple models of different other components that I have built. I tried to include setModel as per views in controller, here is my businessservices controller

class BusinessServicesControllerBusinessServices extends JControllerForm
{
        public function display($cachable = false, $urlparams = false)
        {

            // set default view if not set
            $input = JFactory::getApplication()->input;
            $input->set('view', $input->getCmd('view', 'BusinessServices'));
            $viewName       = $this->input->get('view');
            switch ($viewName)
            {
                case 'businessservices':
                    $viewLayout = $this->input->get('layout', 'default');
                    $view = $this->getView($viewName, $format, '', array('base_path' => $this->basePath, 'layout' => $viewLayout));
                    $view->setModel($this->getModel('businessservices'));
                    break;
                case 'trademark':
                    $viewLayout = $this->input->get('layout', 'default');
                    $view = $this->getView($viewName, $format, '', array('base_path' => $this->basePath, 'layout' => $viewLayout));
                    $view->setModel($this->getModel('trademark'));
                    break;
            }
            // call parent behavior
            parent::display($cachable);
        }
}

also, I tried to include using:

 JLoader::import('joomla.application.component.model');
    JLoader::import( 'llp','components' . DS . 'com_llp_service' . DS . 'models' );
    JLoader::import( 'opc','components' . DS . 'com_opc_services' . DS . 'models' );

and getting the model using getInstance method

$actionsModel = JModel::getInstance('trademark', 'BusinessServicesModel'); 

it is giving some fatal error, that JModel::getInstance you can not use,

so I want know some proper way to doing this task, including all features to the customer dashboard.

Answer 1

Try JModelLegacy:

$actionsModel = JModelLegacy::getInstance('trademark', 'BusinessServicesModel'); 

Maybe you have to include the model file if it is not found:

require_once JPATH_ADMINISTRATOR . '/components/com_llp_service/models/trademark.php';

Please note: The DS constant is not available in newer Joomla versions.
