用于#<ActionView :: Base:0xdb3158>的未定义方法`user_sessions_path'

Question

我收到这个错误,这让我感到困扰.我不知道发生了什么......我已按照T的说明进行操作,但仍在抱怨 - 请帮助!我有错误消息,控制器文件,登录页面和路由文件的摘录.

错误信息

NoMethodError in User_sessions#new
Showing app/views/user_sessions/new.html.erb where line #4 raised:
undefined method `user_sessions_path' for #<ActionView::Base:0x1fe766f>

提取的来源(第4行):

应用程序/视图/用户/ login.rhtml

4. <% form_for @user_session do |f| %>
5.  <%= f.error_messages %>

控制器/ user_sessions_controller.rb

class UserSessionsController < ApplicationController
  before_filter :require_no_user, :only => [:new, :create]
  before_filter :require_user, :only => :destroy

  def new
    @user_session = UserSession.new
  end

  def create
    @user_session = UserSession.new(params[:user_session])
    if @user_session.save
      flash[:notice] = "Login successful!"
      redirect_to root_url
      #redirect_back_or_default account_url
    else
      render :action => :new
    end
  end

  def destroy
    current_user_session.destroy
    flash[:notice] = "Logout successful!"
    redirect_to root_url
    #redirect_back_or_default account_url
  end
end

user_sessions/new.html.erb

#User Login

<% form_for @user_session do |f| %>
  <%= f.error_messages %>

  <p>
    <%= f.label :Email %><br />
    <%= f.text_field :email %>
  </p>
  <p>
    <%= f.label :Password %><br />
    <%= f.password_field :password %>
  </p>
  <p>
    <%= f.submit "Submit" %>
  </p>
<% end %>

routes.rb文件

ActionController::Routing::Routes.draw do |map|
  map.login "login", :controller => "user_sessions", :action => "new"

我在错误的地方看？

问题是你的路线文件.你不是在休息.所以<%form_for @user_session%>不会知道如何创建网址.

添加map.resource: user_session到routes.rb应该可以解决您的问题.

您应该阅读restful_authentication插件的文档.
