Rails的教程3，RSpec的失敗

Question

我通過Ruby on Rails的教程3運行，並且有一個球做，但我剛剛遇到的是沒有得到解決的問題。當我運行我的規格時，兩個測試失敗。

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)>' 

我已經通過我的代碼作爲最好的，我可以比較反對它在書中的代碼搜索，我想出了什麼。我相信這是我錯過的一件愚蠢的小事，我會非常感激第二雙（或更多）眼睛。

這裏是我的測試：

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 

這裏是從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 

在哪裏我應該是極大的讚賞任何想法。

Answer 1

問題的根源並不在規範文件，即使這個問題體現在這些規範文件。教練Michael Hartl更改了以下聲明：

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

聲明。換句話說，他在第一個語句中添加了「：object => f.object」。你必須查看所有具有原始聲明的文件，並將它們更改爲第二個文件。如果你錯過了任何一個，你會有這些錯誤。具體看下面的文件（及任何其他可能有原來的語句）：

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
