Question

我有Rails 4.0.10。我正在关注Michael Hartl的Ruby on Rails教程，我正在尝试构建一个登录功能，但是当我按下登录按钮时出现以下错误：

Routing Error
uninitialized constant SessionController

我完全按照说明操作，所以我很困惑为什么我会收到错误。我做错了什么？

我的会话控制器：

class SessionsController < ApplicationController
  def new
  end

  def create
    user = User.find_by(id: params[session][:id])
    if user && user.authenticate(params[:session][:password])
      log_in user
      redirect_to root_path
    else
      flash.now[:danger] = 'Invalid'
      render 'new'
    end
  end

  def destroy
  end
end

路线：

Website::Application.routes.draw do

  get 'login' => 'sessions#new'
  post 'login' => 'session#create'
  delete 'logout' => 'sessions#destroy'
  get "users/new"
  root 'home_page#home'

end

会话/新视图：

<div id= "admin-sign-in">
  <%= form_for(:session, url: login_path) do |f| %>

    <%= f.label :id %>
    <%= f.text_field :id %>

    <%= f.label :password %>
    <%= f.password_field :password %>

    <%= f.submit "Log in", class: "btn btn-primary" %>
  <% end %>
</div>

Sessions Helper：

module SessionsHelper

  def log_in(user)
    session[:user_id] = user.id
  end
end

用户模型：

class User < ActiveRecord::Base
  has_secure_password
end

用户控制器：

class UsersController < ApplicationController

  def new
    @user = User.new
    @users = User.all
  end

  def create
    @user = User.new(user_params)
    if @user.save
      render :action => "crop"
    else
      render 'new'
    end
  end

  private

    def user_params
      params.require(:user).permit(:password, :password_confirmation)
    end

end

的ApplicationController：

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  include SessionsHelper
end

Answer 1

而不是：

post 'login' => 'session#create'

使用复数：

post 'login' => 'sessions#create'

Rails：路由错误：未初始化的常量SessionController
