RUBY实践—带密码加密的用户创建及修改

开发环境

Ruby: Ruby1.9.1

Rails: Rails2.3.5

Mysql:Mysql5.0.9

Driver:mysql-2.8.1-x86-mingw32.gem

IDE:Rubymine2.0.1

 

一、创建数据表Users

利用RubyMine自带的Scaffold工具创建数据表Users,也可以手动创建

 

二、创建Controller和View

Ruby项目—>右键—>Create Model

完成后将自动生成相应的文件

 

三、修改Model user.rb

利用Digest/SHA1对密码进行加密,实现加密保存

修改后代码如下:

require "digest/sha1" class User < ActiveRecord::Base attr_accessor :hashed_password,:repassword attr_accessible :username, :hashed_password, :repassword validates_uniqueness_of :username validates_presence_of :username, :hashed_password def before_create self.password = User.hash_password(self.hashed_password) end def after_create @hashed_password = nil end def before_update self.password = User.hash_password(self.hashed_password) end def after_update @hashed_password = nil end private def self.hash_password(hashed_password) Digest::SHA1.hexdigest(hashed_password) end end

 

四、修改users_controller.rb

修改update方法,实现当进行edit操作时先判断password与 password_confirm是否一致,

如果一致,则进行update操作,否则提示用户password 与 password_confirm 输入不一致

修改后代码如下:

def update @user = User.find(params[:id]) respond_to do |format| print "user: #{params[:user]}" if params[:user]["hashed_password"] == params[:user]["repassword"] if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end else flash[:notice] = 'Password and Password confirm are not the same' format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end

 

五、修改users/edit.html.erb及users/show.html.erb

对password字段的显示做修改

edit.html.erb修改后代码如下:

Editing user

<% form_for(@user) do |f| %> <%= f.error_messages %>

<%= f.label :username %>
<%= f.text_field :username %>

<%= f.label :password %>
<%= f.password_field :hashed_password %>

<%= f.label :password_confirm %>
<%= f.password_field :repassword %>

<%= f.submit 'Update' %>

<% end %> <%= link_to 'Show', @user %> | <%= link_to 'Back', users_path %>

 

show.html.erb修改后代码如下:

Username: <%=h @user.username %>

Password: <%=h @user.hashed_password %>

<%= link_to 'Edit', edit_user_path(@user) %> | <%= link_to 'Back', users_path %>

 

六、修改routes.rb

添下如下映射规则

map.connect '/users',:controller=>"user",:action=>"index"

 

演示效果:

Create User:

 

 

 

Update User:
