路由错误:未初始化的常量会话

标签: ruby-on-rails ruby session routing

我正在关注this Ruby Railcasts episode以获得一些简单的身份验证,当我导航到登录页面时,我收到错误uninitialized constant Sessions。我检查了我的课程,名字是正确的,这似乎是大多数人报告的问题。知道这里可能会发生什么吗?

我的控制器文件的名称是sessions_controller.rb,代码如下:

class SessionsController < ApplicationController
  def new
  end

  def create
    user = User.authenticate(params[:email], params[:password])
    if user
      session[:user_id] = user.id
      redirect_to root_url, :notice => 'Logged In!'
    else
      flash.now.alert = 'Invalid email or password'
      render 'new'
    end
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_url, :notice => 'Logged Out!'
  end
end

routes.rb文件:

Albumtracker::Application.routes.draw do
  get "login" => "sessions/new", :as => "login"
  get "logout" => "sessions/destroy", :as => "logout"

  get "signup" => "users/new", :as => "sign_up"

  root :to => 'users#new'

  resources :users
  resources :sessions

  get "pages/index"
end

会话/新视图文件:

<h1>Log in</h1>

<%= form_tag sessions_path do %>
  <p>
  <%= label_tag :email %><br />
  <%= text_field_tag :email, params[:email] %>
  </p>
  <p>
  <%= label_tag :password %><br />
  <%= password_field_tag :password %>
  </p>
  <p class="button"><%= submit_tag "Log in" %></p>
<% end %>

您的路线中存在拼写错误。指定控制器和操作时,/应为#。您的路线应如下所示:

get "login" => "sessions#new", :as => "login"
get "logout" => "sessions#destroy", :as => "logout"

get "signup" => "users#new", :as => "sign_up"

在路线中使用/时,前一部分与命名空间匹配。因此,从"sessions/new"路由器尝试找到名为Sessions::NewController的控制器。由于您的应用中不存在名称空间Sessions,因此您获得了未初始化的常量错误。
