I need to render another controller action and i get this error
Missing partial controller/index with {:formats=>[:html], :locale=>[:en, :en], :handlers=>[:rjs, :rhtml, :rxml, :erb, :builder]} in view paths "/path_to/app/views"
how can i render another controller action into a view but without sending an redirect to the client ? I've tried
"index", :controller=>"controller" %> but it seems that is not working.
Try to render template:
"controller/index" %> Or file:
"#{Rails.root}/app/controllers/controller/index" %> And I believe you should render it through controller, as far as it is more convenient:
def your_action ... render :action => :index end This works well for me :
def renderActionInOtherController(controller,action,params) controller.class_eval{ def params=(params); @params = params end def params; @params end } c = controller.new c.request = @_request c.response = @_response c.params = params c.send(action) c.response.body end then, call by
render :text => renderActionInOtherController(OtherController,:otherAction,params) basically it hacks the other class and overwrites its "params" method and return
If you are using Rails 4:
def renderActionInOtherController(controller,action,params) c = controller.new c.params = params c.dispatch(action, request) c.response.body end From Rails Guides page:
Using render with :action is a frequent source of confusion for Rails newcomers. The specified action is used to determine which view to render, but Rails does not run any of the code for that action in the controller. Any instance variables that you require in the view must be set up in the current action before calling render.
So in short you can't render another action, you can only render another template. You could get the shared code and move it to a method in application controller. You could also try something along this lines if you really can't structure your code in some other way:
# This is a hack, I'm not even sure that it will work and it will probably # mess up your filters (like ignore them). other_controller = OtherController.new other_controller.request = @_request other_controller.some_action If you do not want just to render the view of the other controller (/model), but calling the action (method), think more the ruby way of life - put this method(s) into a module and include it in the controllers you need it.
I think its less 'spooky' then somehow touching an other controller.
module StandardActions def show_user_homepage(local_params=params) #something finding #something to check render :"homepage/show" def end class AddressesController
