Well the title Question pretty much sums it up, But I'd like to detail a scenario anyways,
I've created a DemoController, (I have not created a Resource model), and my routes.rb looks like this:
DispatchMe::Application.routes.draw do
root to: "demo#index"
end
From the demo controller I'm dong the following:
class DemoController < ApplicationController
def index
redirect_to :action => 'show'
end
def show
end
end
There is a file in: app/views/demo/show.html.erb of course, And I'd expected that template to be rendered but instead I'm getting the following error:
ActionController::RoutingError (No route matches [GET] "/assets")
and this URL is generated as a result from the redirect:
/assets?action=show&controller=demo
Am I missing something here? I thought rails was supposed to render the action's template for such cases.
Note. I understand that If I create a route like get 'show' => "demo#show" and call redirect_to show_path it'll work just fine, But I need to know if that's mandatory?
Thank you very much!
For the desired behavior, use render
instead of redirect_to
:
class PagesController < ApplicationController
def index
render :action => "show"
end
def show
end
end
EDIT:
You can use redirect_to
on other actions, but from what I can tell, the index action sets the base path. To simplify route definition, use resources :controller_name
. You can view the routes generated by resources by typing rake routes
in your command line.
Example:
demo_controller.rb
class DemoController < ApplicationController
def index
end
def show
redirect_to :action => 'index'
end
end
routes.rb
DispatchMe::Application.routes.draw do
root to: "demo#index"
resources :demo
end
