Rails 4：response_with参数错误

Question

in my rails app (v. 4.1.9) i get the following error after a create action:

arguments passed to url_for can't be handled. Please require routes or provide your own implementation

Here is my code:

routes.rb

scope module: :explore do
  resources :questions
end

questions_controller.rb

class Explore::QuestionsController < Explore::BaseController
  respond_to :html
  authorize_resource

  def create
    @question = Question.new question_params
    @question.save

    respond_with @question
  end
end

I also tried respond_with question_path and redirect_to question_path but always the same error.

Any ideas?

Answer 1

I found my problem. In a helper I included ActionView::Helpers::UrlHelper . After removing this, respond_with and redirect_to works fine.

Answer 2

Try this

def create
    @question = Question.new question_params
    if @question.save
        flash[:success] = "Question created!"
        redirect_to questions_path
        or 
        redirect_to :controller => 'questions', :action => 'new'
        or
        redirect_to :back
    end
end
