我正在运行 Ruby on Rails 教程 3，并且正在做一个球，但我刚刚遇到了一些没有得到解决的问题。当我运行我的规范时，两个测试失败了。

Failures:
  1) UsersController PUT 'update' failure should render the 'edit' page
  Failure/Error: put :update, :id => @user, :user => @attr
  undefined local variable or method `object' for #<#<Class:0x00000102c861c8>:0x00000101d25558>
 # ./app/views/shared/_error_messages.html.erb:3:in `_app_views_shared__error_messages_html_erb___3390867530789228804_2170854120__2806434579894406668'
 # ./app/views/users/edit.html.erb:4:in `block in _app_views_users_edit_html_erb__558009768664311469_2170714160__919273585470661416'
 # ./app/views/users/edit.html.erb:3:in `_app_views_users_edit_html_erb__558009768664311469_2170714160__919273585470661416'
 # ./app/controllers/users_controller.rb:47:in `update'
 # ./spec/controllers/users_controller_spec.rb:158:in `block (4 levels) in <top (required)>'

2) UsersController PUT 'update' failure should have the right title
 Failure/Error: put :update, :id => @user, :user => @attr
 undefined local variable or method `object' for #<#<Class:0x00000102c861c8>:0x00000101b211f8>
 # ./app/views/shared/_error_messages.html.erb:3:in `_app_views_shared__error_messages_html_erb___3390867530789228804_2170854120__2806434579894406668'
 # ./app/views/users/edit.html.erb:4:in `block in _app_views_users_edit_html_erb__558009768664311469_2170714160__919273585470661416'
 # ./app/views/users/edit.html.erb:3:in `_app_views_users_edit_html_erb__558009768664311469_2170714160__919273585470661416'
 # ./app/controllers/users_controller.rb:47:in `update'
 # ./spec/controllers/users_controller_spec.rb:163:in `block (4 levels) in <top (required)>'

我已经尽可能地搜索了我的代码，并将其与书中的代码进行了比较，但我一无所获。我确信这是我错过的一件愚蠢的小事，我将非常感谢第二双（或更多;）眼睛。

这是我的测试：

describe "failure" do
  before(:each) do
    @attr = { :email => "", :name => "", :password => "", :password_confirmation => "" }
  end

  it "should render the 'edit' page" do
    put :update, :id => @user, :user => @attr
    response.should render_template('edit')
  end

  it "should have the right title" do
    put :update, :id => @user, :user => @attr
    response.should have_selector("title", :content => "Edit User")
  end
end

这是 users_controller 的更新方法：

def update
@user = User.find(params[:id])
if @user.update_attributes(params[:user])
  flash[:success] = "Profile updated"
  redirect_to @user
else
  @title = "Edit User"
  render 'edit'
end
end

任何关于我应该看哪里的想法都非常感谢。

即使问题在那些规范文件中表现出来，问题的根源也不在规范文件中。讲师 Michael Hartl 更改了以下声明：

<%= render 'shared/error_messages' %
                  to 
<%= render 'shared/error_messages', :object => f.object %>

陈述。换句话说，他在第一条语句中添加了“, :object => f.object”。您必须查看所有具有原始语句的文件并将它们更改为第二个。如果您错过其中任何一个，您将遇到这些错误。具体查看以下文件（以及任何其他可能有原始声明的文件）：

app/views/users/edit.html.erb
app/views/users/fields.html.erb
app/views/users/new.html.erb
app/views/shared/micropost_form.html.erb
