Question

我尽力了。我正在添加我的所有文件，请看看。

我跑了：

rake db:drop（删除表格）
rake db:create（创建数据库）
rake db:migrate（创建表格）
rake db:test:prepare（创建测试数据库）

控制器文件：

class UsersController<ApplicationController
  respond_to :html, :json

  def new
    @user = User.new  
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      redirect_to root_url, notice: "Thank you for siging up!"
    else
      render "new"
    end
  end

end

我的html.erb文件。

<h1>login</h1>
<% form_for @user do |f|%>
<% if @user.errors.any? %>
<div class="error_message">
<h2>Form is invalid</h2>
<ul>
    <% @user.error.full_message.each do |message| %>
    <li><%= message%></li>
    <% end %>
   </ul>
 </div>
 <% end %>
 <div class="field">
<%= f.label  :email %><br />
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :password %><br />
 <%= f.password_field :password %>
 </div>
 <div class="field">
   <%= f.label :password_confirmation %><br />
   <%= f.password_field :password_confirmation %>

 </div>
 <div class="action"><%= f.submit %></div>
 <% end %>

我的user.erb文件。 class User＆lt;的ActiveRecord ::基

 has_secure_password

 attr_accessible :email, :password, :password_confirmation

 validates_uniqueness_of :email
end

错误完全跟踪。
