ruby-on-rails - 缺少 Rails 模板

Question

您好，有谁知道是什么导致了这个错误。

我是 Rails 的新手，但我猜它与 Bootstrap 有关。但是，我不知道如何修复它，过去 2 小时我一直在尝试。

Error

Template is missing
Missing template authentication/account_settings, application/account_settings with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "/home/action/workspace/PAW/app/views" * "/home/action/.rvm/gems/ruby-2.1.1/gems/twitter-bootstrap-rails-2.2.8/app/views"

我在身份验证 Controller 中定义了account_settings

authentication_controller.rb

    @user = User.new

    username_or_email = params[:user][:username]
    password = params[:user][:password]

    if username_or_email.rindex('@')
      email=username_or_email
      user = User.authenticate_by_email(email, password)
    else
      username=username_or_email
      user = User.authenticate_by_username(username, password)

    if user
      session[:user_id] = user.id

      redirect_to '/home'

    @user = current_user

  def set_account_info
    old_user = current_user

    # verify the current password by creating a new user record.
    @user = User.authenticate_by_username(old_user.username, params[:user][:password])

    # verify
    if @user.nil?
      @user = current_user
      @user.errors[:password] = "Password is incorrect"

    else
      # update the user with any new username and email
      @user.update(params[:user])
      # Set the old email and username, which is validated only if it has changed.
      @user.previous_email = old_user.email
      @user.previous_username = old_user.username

      if @user.valid?
    # If there is a new_password value, then we need to update the password.
    @user.password = @user.new_password unless @user.new_password.nil? || @user.new_password.empty?

    redirect_to :root

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  # root 'welcome#index'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end
  #
  #     collection do
  #       get 'sold'
  #     end
  #   end

  # Example resource route with sub-resources:
  #   resources :products do
  #     resources :comments, :sales
  #     resource :seller
  #   end

  # Example resource route with more complex sub-resources:
  #   resources :products do
  #     resources :comments
  #     resources :sales do
  #       get 'recent', on: :collection
  #     end
  #   end

  # Example resource route with concerns:
  #   concern :toggleable do
  #     post 'toggle'
  #   end
  #   resources :posts, concerns: :toggleable
  #   resources :photos, concerns: :toggleable

  # Example resource route within a namespace:
  #   namespace :admin do
  #     # Directs /admin/products/* to Admin::ProductsController
  #     # (app/controllers/admin/products_controller.rb)
  #     resources :products
  #   end
end

Answer 1

Controller 方法:

  def account_settings
    @user = current_user
  end

正在寻找呈现位于以下位置的模板文件:

views/authentication/account_settings.html.erb(或.jbuilder等)

那个文件存在吗？如果没有，您应该创建它。
