render :action with params
提问by Swann
I have one Class with 2 methods. The first method is called by the view with some GET parameters ( params[:page] ). I would like to save those params and send them by a render action to my second method.
我有一个带有 2 种方法的类。第一个方法由带有一些 GET 参数（ params[:page] ）的视图调用。我想保存这些参数并通过渲染操作将它们发送到我的第二种方法。
class exemple
def first
## sql save of params[:page]
render :action => "second"
end
def second
##
## Here I need my params[:page] to do paginate stuff
##
respond_to do |format|
format.html
end
end
end
So my question is : How can I send params with a render :action ?
所以我的问题是：如何使用 render :action 发送参数？
thanks :)
谢谢 ：）

render :action => "second"
When you render, then your method written in :actionis not called, only the view with that action name is called.
渲染时，:action不会调用写入的方法，只会调用具有该操作名称的视图。
In your example, when you render, then your method secondis not called but you are instead rendering the second.html.erbview.
在您的示例中，当您渲染时，second不会调用您的方法，而是渲染second.html.erb视图。

To call that method you have to use redirect_to, which looks something like the following:
要调用该方法，您必须使用redirect_to，如下所示：
redirect_to :action => "second", :page=> 4
