ruby-on-rails - Rails 4：respond_with参数错误

Question

在我的 Rails 应用程序（v. 4.1.9）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：

路线.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

我也尝试过respond_with question_path，redirect_to question_path但总是同样的错误。

有任何想法吗？

Answer 1

我发现了我的问题。在我包含的助手中ActionView::Helpers::UrlHelper。删除后，respond_with工作redirect_to正常。

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
