Ruby on Rails ActionController Redirecting
Example
Assuming the route:
resources :users, only: [:index]
You can redirect to a different URL using:
class UsersController
def index
redirect_to "http://stackoverflow.com/"
end
end
You can go back to the previous page the user visited using:
redirect_to :back
Note that in Rails 5 the syntax for redirecting back is different:
redirect_back fallback_location: "http://stackoverflow.com/"
Which will try to redirect to the previous page and in case not possible (the browser is blocking the HTTP_REFERRER header), it will redirect to :fallback_location
