Rendering views in other places in Yii2 - no renderPartial?
提问by Brett
I need to render a partial view inside a custom component file in Yii2and according to the Yii docsyou can access the view instance via something like this:
我需要在自定义组件文件中渲染局部视图Yii2，根据Yii 文档，您可以通过以下方式访问视图实例：
\Yii::$app->view->renderFile('@app/views/site/license.php');
I went ahead and tried:
我继续尝试：
Yii::$app->view->renderPartial('//my/view/');
...but then got an error that I was trying to access a non-existent method.
...但后来得到一个错误，我试图访问一个不存在的方法。
I then checked out the view classand noticed it doesn't have a renderPartialand this is a method of the controllerclass instead.
然后我检查了视图类，发现它没有 a renderPartial，而是控制器类的一个方法。
I see it has a renderFilemethod and a rendermethod; which of these should I use?
我看到它有一个renderFile方法和一个render方法；我应该使用哪些？
The docs don't state the rendermethod includes the layout like the method of the same name from the controllerclass, so I'm not sure; as for renderFileI'm not 100% sure if that is suitable either?
文档没有说明该render方法包括布局，如控制器类中的同名方法，所以我不确定；至于renderFile我也不是 100% 确定这是否合适？
Could someone explain which method would produce the same results that renderPartialproduces?
有人能解释一下哪种方法会产生与产生相同的结果renderPartial吗？

You can call renderPartialfrom Yii::$app->controller->renderPartial('myview');Also as you can see from source code of yii\base\ControllerrenderPartialcalls View's rendermethod so you can use Yii::$app->view->render. Basically there is no difference between renderand renderFile, because renderinternally calls renderFile. But when you use renderyou can pass $viewin several formats like path alias, absolute path whithin applicationor whithin moduleand relative path. And to renderFileyou can pass only absolute file path or path alias.
您可以renderPartial从yii\base\Controller 的源代码中Yii::$app->controller->renderPartial('myview');也可以看到调用 View 的方法，因此您可以使用. 和之间基本上没有区别，因为在内部调用. 但是当您使用时，您可以传入多种格式，例如路径别名、应用程序的绝对路径或模块和相对路径。并且您只能传递绝对文件路径或路径别名。renderPartialrenderYii::$app->view->renderrenderrenderFilerenderrenderFilerender$viewrenderFile
