如何在joomla MVC组件中使用多个模型 [英] How to use multiple models in joomla MVC Component
问题描述
我在joomla中使用的视图不同于视图自身的模型,该模型与视图的名字相似,是通过控制器分配的,例如:
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'));
现在如何在视图中使用其方法getSingleUser($ user_id).在joomla文档的示例中,它使用的是这样的东西:
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");
所以我假设data1是model2中方法的名称?如果是这样,那么在我的情况下如何传递userid参数.我知道这是许多joomla开发人员所做的一件容易的事,但是我是各种开发人员的杰作,并且是joomla的新手,所以我希望你们能告诉我.
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 .
推荐答案
第一种方法
我是通过如下修改控制器(这是用户的控制器)来实现的
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 );
$view->display(); // now our view has both models at hand
}
然后,您可以在视图中简单地对模型进行操作
In the view you can then simply do your operations on the models
function display($tpl = null){
$userModel = &$this->getModel(); // get default model
$billsModel = &$this->getModel('bills'); // get second model
// do something nice with the models
parent::display($tpl); // now display the layout
}
替代方法
在视图中直接加载模型:
In the view directly load the model:
function display($tpl = null){
// assuming the model's class is MycomponentModelBills
// second paramater is the model prefix
$actionsModel = & JModel::getInstance('bills', 'MycomponentModel');
}
