设计 sign_in 页面未在 rails 4.2.1 中以单独的布局呈现

Question

我想为正在运行的设计签名设置单独的布局。

我在我的应用程序控制器中使用以下代码。

class ApplicationController < ActionController::Base

  protect_from_forgery with: :exception
  before_action :configure_permitted_parameters, if: :devise_controller?
  layout :layout_by_resource

  def after_sign_in_path_for(resource)
  stored_location_for(resource) ||
    if resource.is_a?(User) 
      new_applicant_response_url

    else
      homepage_admin_page_path

    end
end

  protected

  def layout_by_resource
    if devise_controller?
      "layout_name_for_devise"
    else
      "application"
    end
  end

  protected
        def configure_permitted_parameters
            devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:assessment_id, :name, :email, :password, :password_confirmation, :remember_me) }
            devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :email, :password, :remember_me) }
            devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:name, :email, :password, :password_confirmation, :current_password) }
        end

end

并且我生成了设计视图并向设计登录页面添加了一些样式。

当我点击 devise/sign_in 时，我在终端中得到以下输出

Started GET "/admins/sign_in" for 127.0.0.1 at 2015-07-24 12:39:49 +0530
Processing by Devise::SessionsController#new as HTML
  Rendered devise/shared/_links.html.erb (0.9ms)
  Rendered devise/sessions/new.html.erb within layouts/layout_name_for_devise (6.9ms)
Completed 200 OK in 21ms (Views: 8.4ms | ActiveRecord: 1.0ms)

我正在为此设计登录操作正确获取布局。但是在那个布局设计中 sign_in 表单不渲染，只有布局在渲染。

您的布局可能没有在其中调用 yield。
