新安裝設計登錄的問題（RegistrationController＃create中的ActionController :: UnknownFormat）

Question

我剛剛將手機登錄系統的應用程序切換爲使用Devise寶石。我之前曾使用過許多應用程序，但從未遇到過這個問題。所有觀點都正確實現，並且顯示的時候就應該，但是當我嘗試創建一個新註冊時，我得到以下錯誤：

ActionController::UnknownFormat in RegistrationsController#create

它給人的軌跡如下：

當我嘗試登錄時，我還會看到一個空白的白色屏幕，上面寫着「您需要先登錄或註冊才能繼續」。

我認爲這些錯誤是相關的，但因爲我沒有經驗與這組錯誤Devise我不是100％確定。任何人都可以幫我弄清楚這裏有什麼問題嗎？

附加信息

下面是registrations#new代碼：

<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 --> 

這裏有一個補充registrations_controller一些添加的列：

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 

而這裏的它是如何體現在我的路線：

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

Answer 1

原來設計這個自動生成兩個registrations#new和sessions#new：

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

，當我每個窗體上去除(resource_name)錯誤消失。
