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: <h1>Editing user</h1> <% form_for(@user) do |f| %> <%= f.error_messages %> <p> <%= f.label :username %><br /> <%= f.text_field :username %> </p> <p> <%= f.label :password %><br /> <%= f.password_field :hashed_password %> </p> <p> <%= f.label :password_confirm %><br /> <%= f.password_field :repassword %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @user %> | <%= link_to 'Back', users_path %> show.html.erb修改后代码如下: <p> <b>Username:</b> <%=h @user.username %> </p> <p> <b>Password:</b> <%=h @user.hashed_password %> </p> <%= 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: |
