新しくインストールされたDeviseログインに関する問題（RegistrationsController＃createのActionController :: UnknownFormat）

Question

私は、Devise gemを使用するために手作業のログインシステムから自分のアプリケーションを切り替えたばかりです。これまで多くのアプリでこの宝石を使っていましたが、この問題は一度も起こりませんでした。すべてのビューが正しく実装されたときに彼らが必要表示するが、私は新しい登録を作成しようとすると、私は次のエラーを取得している：

ActionController::UnknownFormat in RegistrationsController#create

ログインしようとすると、「続行する前にサインインまたはサインアップする必要があります」という空白の画面が表示されます。

私はこれらのエラーは関連していると思いますが、私はDeviseでこのエラーのセットを経験していないので、100％確実ではありません。誰も私がここで何がうまくいかないのか把握するのを助けることができる？

ADDITIONAL INFORMATION

ここregistrations#newためのコードです：

<div class="hero-image-row"> 
    <div class="hero-image-outer text-center"> 
    <div class="hero-image-inner text-center"> 
     <%= image_tag 'Background 17.jpg', class: "hero-image",alt: "Beautiful golf hole by the ocean" %> 
    </div> <!-- hero-image-inner --> 
    </div> <!-- hero-image-inner --> 
</div> <!-- row --> 

<div class="overlap-hero-image"> 
    <div class="buffer-25"></div> 
    <div class="buffer-50"></div> 
    <div class="container"> 
    <div class="container text-center col-xs-10 col-xs-push-1" style="background-color: rgba(235, 235, 235, 0.8) !important"> 
     <h1 style="color: black">Sign Up</h1> 

     <%= simple_form_for(resource, as: resource_name, url: user_registration_path(resource_name)) do |f| %> 
     <%= f.error_notification %> 

     <div class="form-inputs text-left row"> 
      <div class="col-sm-12"> 
      <%= f.input :email, required: true, autofocus: true %> 
      </div> 
      <div class="col-sm-6"> 
      <%= f.input :password, required: true, hint: ("#{@minimum_password_length} characters minimum" if @minimum_password_length) %> 
      </div> 
      <div class="col-sm-6"> 
      <%= f.input :password_confirmation, required: true %> 
      </div> 
     </div> 

     <div class="form-actions"> 
      <%= f.button :submit, "Sign up" %> 
     </div> 
     <% end %> 

     <%= render "devise/shared/links" %> 
    </div> <!-- columns box --> 
    </div> <!-- container --> 
</div> <!-- overlap-tall-hero-image --> 

は、ここではいくつかの追加の列のための補助的なregistrations_controllerです：

class RegistrationsController < Devise::RegistrationsController 
    private 

    def sign_up_params 
    params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :gender, :birthday, :dom_hand, :sport, :g_years, :g_rounds, :g_practice, :handicap, :g_score, :admin) 
    end 

    def account_update_params 
    params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :current_password, :gender, :birthday, :dom_hand, :sport, :g_years, :g_rounds, :g_practice, :handicap, :g_score, :admin) 
    end 
end 

そして、ここではそれが私のルートに反映されます方法は次のとおりです。

devise_for :users, :controllers => { registrations: 'registrations' } 

Answer 1

それは工夫がregistrations#newとsessions#newの両方のためにこれを自動生成することが判明：私は、各フォームに(resource_name)を削除するときにエラーが消え

<%= simple_form_for(resource, as: resource_name, url: user_registration_path(resource_name)) do |f| %> 

。
