Rails 验证 - 确认不正确

Question

我正在尝试在 Rails4 中进行确认验证，但它不能正常工作。 当我提交表单时，消息是“电子邮件确认不能为空”而不是“电子邮件与确认不匹配” 这是我的代码：

enter code here
#model user.rb
class User < ActiveRecord::Base
validates :email, confirmation: true
validates :email_confirmation, presence: true
end

#view     
<div class="field">
<%= f.label :email_confirmation %><br>
<%= f.text_field :email_confirmation %>
</div>
#controller
def create
@user = User.new(user_params)
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully    created.' }
format.json { render :show, status: :created, location: @user }
else
format.html { render :new }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end

Answer 1

您可以创建自定义验证来检查两个字段是否相同

validate :check_email

def check_email
  errors.add(:email_comfirmation, "Test message") if email == email_confirmation
end
