问题
I am using different model in joomla than view's own model that is similar to its name by assigning it from controller, like:
$view->setModel($this->getModel('user'));
Now how can I use its method getSingleUser($user_id) in view. In an example in joomla documentation , it is using is some thing like this:
$this->get("data1","model2");
So I assume data1 is name of method in model2? If so then how can I pass argument that is userid in my case. I know this is easy thing that many of joomla developers have done but I am sort of jack of all sort of developer and new to joomla so I am expecting you guys to tell me .
回答1:
First approach
I did this by modifying the controller as follows (this is the controller for user)
function doThis(){ // the action in the controller "user"
// We will add a second model "bills"
$model = $this->getModel ( 'user' ); // get first model
$view = $this->getView ( 'user', 'html' ); // get view we want to use
$view->setModel( $model, true ); // true is for the default model
$billsModel = &$this->getModel ( 'bills' ); // get second model
$view->setModel( $billsModel );
$view->display(); // now our view has both models at hand
}
In the view you can then simply do your operations on the models
function display($tpl = null){
$userModel = &$this->getModel(); // get default model
$billsModel = &$this->getModel('bills'); // get second model
// do something nice with the models
parent::display($tpl); // now display the layout
}
Alternative approach
In the view directly load the model:
function display($tpl = null){
// assuming the model's class is MycomponentModelBills
// second paramater is the model prefix
$actionsModel = & JModel::getInstance('bills', 'MycomponentModel');
}
