我正在阅读其中一个 Rails 教程,在有关用户验证的部分中,我不断收到错误消息,告诉我在编辑/创建用户时我的密码确认不能为空。我查看了以前的答案,看起来人们使用了 attr_accessible,它被拉出了轨道。我是一个完全的 rails/web dev 新手,所以我不知道如何继续。该视图在 HAML 中,如果这是不好的做法,请见谅。
模型
class User < ActiveRecord::Base
before_save { self.email = email.downcase }
attr_accessor :name, :email
validates_confirmation_of :password
has_secure_password
validates :name, presence: true, length:{ maximum: 16 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
validates :password, length: { minimum: 6 }
has_one :profile
has_many :posts
end
看法
= form_for(@user) do |f|
- if @user.errors.any?
#error_explanation
%h2
= pluralize(@user.errors.count, "error")
prohibited this username from being saved:
%ul
- @user.errors.full_messages.each do |msg|
%li= msg
.field
= f.label :name
= f.text_field :name
.field
= f.label :email
=f.text_field :email
.field
= f.label :password
= f.password_field :password
= f.label :password_confirmation
= f.password_field :password_confirmation
.actions
= f.submit
