Rails 4：response_with参数错误

Question

在我的Rails应用程序（4.1.9版）中，创建操作后出现以下错误：

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

这是我的代码：

的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

我也尝试了respond_with question_path和redirect_to question_path respond_with question_path ，但是总是相同的错误。

有任何想法吗？

Answer 1

我发现了问题。 在帮助器中，我包含了ActionView::Helpers::UrlHelper 。 删除此选项后， respond_with和redirect_to可以正常工作。

Answer 2

尝试这个

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
