Rails的教程3，RSpec的失败

Question

我通过Ruby on Rails的教程3运行，并且有一个球做，但我刚刚遇到的是没有得到解决的问题。当我运行我的规格时，两个测试失败。

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)>' 

我已经通过我的代码作为最好的，我可以比较反对它在书中的代码搜索，我想出了什么。我相信这是我错过的一件愚蠢的小事，我会非常感激第二双（或更多）眼睛。

这里是我的测试：

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 

这里是从users_controller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 

在哪里我应该是极大的赞赏任何想法。

Answer 1

问题的根源并不在规范文件，即使这个问题体现在这些规范文件。教练Michael Hartl更改了以下声明：

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

声明。换句话说，他在第一个语句中添加了“：object => f.object”。你必须查看所有具有原始声明的文件，并将它们更改为第二个文件。如果你错过了任何一个，你会有这些错误。具体看下面的文件（及任何其他可能有原来的语句）：

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
