在学习rails的过程中碰到一个问题：validates_confirmation_of :password :on => :create不生效，请教各位。 rails 1.2.6.
class Member < ActiveRecord::Base
attr_accessor :password_confirmation
belongs_to :current_addr, :class_name => 'Location', :foreign_key => "address"
belongs_to :hometown_addr, :class_name => 'Location', :foreign_key => "hometown"
validates_confirmation_of :password, :message => '密码不一致', :on => :create
validates_presence_of :email, :password
validates_uniqueness_of :email
end
class MemberController < ApplicationController
def index
list
render :action => 'list'
end
def new
if request.get?
@member = Member.new
else
@member = Member.new(params[:member])
if @member.create
redirect_to(:action => "index")
end
end
end
def destroy
Member.find(params[:id]).destroy
redirect_to :action => 'list'
end
end
而validates_confirmation_of :password，采用@member.save却有效，不懂。 声明：JavaEye文章版权属于作者，受法律保护。没有作者书面许可不得转载。

请自己看rails文档
注意黑体字部分 引用 doc/api/classes/ActiveRecord/Validations/ClassMethods.html#M001332 validates_confirmation_of(*attr_names) Encapsulates the pattern of wanting to validate a password or email address field with a confirmation. Example:
Model:
class Person < ActiveRecord::Base
validates_confirmation_of :user_name, :password
validates_confirmation_of :email_address, :message => "should match confirmation"
end
View:
<%= password_field "person", "password" %>
<%= password_field "person", "password_confirmation" %>
The added password_confirmation attribute is virtual; it exists only as an in-memory attribute for validating the password. To achieve this, the validation adds acccessors to the model for the confirmation attribute. NOTE: This check is performed only if password_confirmation is not nil, and by default only on save. To require confirmation, make sure to add a presence check for the confirmation attribute: validates_presence_of :password_confirmation, :if => :password_changed? Configuration options: * message - A custom error message (default is: "doesn‘t match confirmation") * on - Specifies when this validation is active (default is :save, other options :create, :update) * if - Specifies a method, proc or string to call to determine if the validation should occur (e.g. :if => :allow_validation, or :if => Proc.new { |user| user.signup_step > 2 }). The method, proc or string should return or evaluate to a true or false value. * unless - Specifies a method, proc or string to call to determine if the validation should not occur (e.g. :unless => :skip_validation, or :unless => Proc.new { |user| user.signup_step <= 2 }). The method, proc or string should return or evaluate to a true or false value. |
