##controllers 文件

def new @user = Users.new end

def create @user = Users.new(params[:user]) if @user.save redirect_to :action => :index flash[:notice] = "event was successfully created" else render :action => :register end end

html 的

<%= form_for @user, :url => { :controller => 'users', :action => 'create'} do |f| %>

• <%= f.label :name, "用户名 (邮箱)" %>

  <%= f.text_field :name,:class => "txt-ctrl"%>

• <%= f.label :password, "密码" %> <%= f.password_field :password,:class => "txt-ctrl"%>

<% if @user.errors.any? %>

<% @user.errors.full_messages.each do |msg| %>
• <%= msg %>
<% end %>

<% end %>

<%= f.submit "注册" > <% end %>

在 create 函数里面，@user出来的都是空值。。
