ruby-on-rails – Rails设计用户存在空DB

概述我正在尝试通过设计创建一个用户,但我遇到了问题. 家园 def land @resource = User.new @devise_mapping = Devise.mappings[:user]end land.html.haml = form_for @resource, :as => :user, :url => registration_path(:user), :remote 我正在尝试通过设计创建一个用户,但我遇到了问题.

家园

def land  @resource = User.new  @devise_mapPing = Devise.mapPings[:user]end

land.HTML.haml

= form_for @resource,:as => :user,:url => registration_path(:user),:remote => true do  = label_tag 'user[email]',raw("<h3>Stay Informed!</h3>")  = text_fIEld_tag 'user[email]',nil,{:placeholder => "Your email",:required => true}  %input(type="submit" name="commit" value="Add")

user.rb

class User < ActiveRecord::Base  before_valIDation(:on => :create) do    self.password = "none"    self.password_confirmation = "none"  end  # Include default devise modules. Others available are:  # :token_authenticatable,:encryptable,:confirmable,:lockable,:timeoutable and :omniauthable  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:trackable,:valIDatable  # Setup accessible (or protected) attributes for your model  attr_accessible :email,:password,:password_confirmation,:remember_meend

正在使用Default Devise :: RegistrationsController.

这在提交时出现：

development.log

Started POST "/users" for 127.0.0.1 at 2013-04-24 20:49:46 -0300Processing by Devise::RegistrationsController#create as Js  Parameters: {"utf8"=>"✓","user"=>{"email"=>"me@mjohnst.com"},"commit"=>"Add"}  [1m[35m (0.3ms)[0m  BEGIN  [1m[36mUser Exists (0.5ms)[0m  [1mSELECT 1 AS one FROM "users" WHERE "users"."email" = 'me@mjohnst.com' liMIT 1[0m  [1m[35m (0.2ms)[0m  RolLBACK  Rendered devise/registrations/create.Js (0.4ms)Completed 200 OK in 84ms (VIEws: 4.1ms | ActiveRecord: 1.0ms)

但是,在rails控制台中：

2.0.0p0 :011 > User.all  User Load (0.5ms)  SELECT "users".* FROM "users" => #<ActiveRecord::Relation []>

和localhost：5000 /用户完全是空的…

当我的数据库中没有用户时,为什么我会收到用户存在和RolLBACK？

解决方法 用户存在查询来自验证器检查没有用户使用您尝试注册的相同电子邮件.永远不会有INSERT查询,因此您的用户永远不会被注册.

这可能是验证失败.在这种情况下,您的密码可能太短(默认的Devise密码长度验证要求至少长度为8,您的密码长度仅为4).

您正在收到成功的200响应,因为它正在重定向回注册,并显示一条Flash消息,说明哪些验证失败.
