嗨,大家好,我是新来的rails,只是做我的第一个注册表单。我有一些验证,我希望轨检查,但由于某种原因,它不显示错误消息。Rails没有显示验证错误信息
在视图/用户/ signup.html.erb我有这个
<h1>Register Now!</h1>
<% form_for :user, @u, :url => { :action => "signup" } do |f| %>
<%= f.error_messages :header_message => "Please Try Again!", :message => "We had some problems processing your registration" %>
<%= f.label(:first, "First Name")%>
<%= f.text_field(:first) %><br/>
<%= f.label(:last, "Last Name")%>
<%= f.text_field(:last) %><br/>
<%= f.label(:username, "Username")%>
<%= f.text_field(:username) %><br/>
<%= f.label(:password, "Password")%>
<%= f.password_field(:password) %><br/>
<%= f.label(:password_confirmation, "Confirm Password")%>
<%= f.password_field(:password_confirmation) %><br/>
<%= f.label(:email, "E-mail")%>
<%= f.text_field(:email) %> <br/>
<%= f.label(:terms_of_service, "I agree to the terms of service") %>
<%= f.check_box(:terms_of_service) %><br/>
<%= f.submit("Sign Up")%>
<% end %>
在模型中,我有以下
class User < ActiveRecord::Base
validates_length_of :username, :within =>4..15
validates_length_of :password, :within => 3..520
validates_presence_of :first, :last, :username, :email, :password, :password_confirmation
validates_uniqueness_of :username, :email
validates_confirmation_of :password
validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "Invalid email"
validates_acceptance_of :terms_of_service, :message => "You must agree to our Terms of Service in order to create account"
end
控制器
class UserController < ApplicationController
def index
@users = User.find(:all)
end
def signup
if !params[:commit]
render :action =>'signup'
else
@u = User.new
@u.first = params[:first]
@u.last = params[:last]
@u.email = params[:email]
@u.username = params[:username]
@u.password = params[:password]
@u.password_confirmation = params[:password_confirmation]
@u.terms_of_service = params[:terms_of_service]
if @u.valid?
@u.password = Digest::SHA512.hexdigest(params[:password])
@u.password_confirmation = Digest::SHA512.hexdigest(params[:password_confirmation])
@u.save!
render :action => 'success'
else
render :action => 'signup'
end
end
end
end
编辑:由于某种原因更新了我的代码,现在我无法创建用户。它会给我错误。 任何人都知道如何解决这个问题?
在您的控制器中,您试图保存的用户实例名为'@user'? – jdeseno 2010-08-04 08:18:32
jdeseno是正确的,你应该发布你的控制器代码或只是行动显示和注册 – Bohdan 2010-08-04 12:55:37
没关系,我得到这个固定的 – denniss 2010-08-05 06:31:04
