【问题描述】：

我有瞳孔模型。所以我可以保存和编辑瞳孔。学生有_one 电话（和电话属于_学生）和应用程序通过嵌套属性保存学生的手机。一切都在浏览器中运行良好，但是当我尝试更新 Pupil 模型时，我遇到了一些麻烦。

控制器：

class PupilsController < ApplicationController
  ...

  def edit
    @pupil = Pupil.find( params[:id] )
  end

  def update    
    pupil = Pupil.find( params[:id] )

    if pupil.update_attributes( params[:pupil] )
      redirect_to pupils_path
      ...
    else
      redirect_to edit_pupil_path
      ...
    end
  end
end

查看编辑页面：

<%= form_for @pupil, :html => {:class => "form-horizontal"} do |f| %>
  <%= field_set_tag do %>
    ...
    <div class="control-group">
      <%= f.label :pupil_address_of_living, "Address of living", :class => "control-label" %>

      <div class="controls">
        <%= f.text_area :pupil_address_of_living, :rows => 3, 
                        :placeholder => @everpresent_field_placeholder %>
      </div>
    </div>

    <hr/>

    <%= f.fields_for :pupil_phone do |pp| %>                                              
      <div class="control-group">
        <%= pp.label :pupil_home_number, "Home phone", :class => "control-label" %> 

        <div class="controls">
          <%= pp.text_field :pupil_home_number, :placeholder => @everpresent_field_placeholder %>
        </div>
      </div>
      ...
    <% end %>


    <%= f.submit "Change", :class => "btn btn-large btn-warning" %>
  <% end %>  
<% end %>

我的集成测试实际上失败了：

# encoding: UTF-8
require 'spec_helper'

describe "SchoolHeads" do
  before(:each) do
    @attr = {
              :user_login => "iSchool_head",
              :password => "foobar"
            }

    user = User.new( @attr )
    user.user_role = "school_head"
    user.save!
  end

  ...
    describe "Updating" do
      describe "View" do
        before(:each) do
          @ipupil = Factory( :pupil, :pupil_phone => Factory( :pupil_phone ))            
          visit edit_pupil_path( :id => @ipupil.id )
        end 

        it "should have values in forms" do     
          response.should have_selector("form") do |form|
          ... 
          form.should have_selector("input", :name => "pupil[pupil_phone_attributes][pupil_home_number]")
        end
      end
    end

错误来自我的测试：

Failure/Error: form.should have_selector( "input",
expected following output to contain a <input name='pupil[pupil_phone_attributes][pupil_home_number]'/> tag:

<form accept-charset="UTF-8" action="/pupils/220" class="form-horizontal" id="edit_pupil_220" method="post">
  <div style="margin:0;padding:0;display:inline">
    <input name="utf8" type="hidden" value="✓"><input name="_method" type="hidden" value="put">
  </div>
  <fieldset>
    ...      
    <div class="control-group">
      <label class="control-label" for="pupil_pupil_address_of_living">Address of living</label>
      <div class="controls">
        <textarea cols="40" id="pupil_pupil_address_of_living" name="pupil[pupil_address_of_living]" rows="3">Moscow</textarea>
       </div>
     </div>

     <hr>

     # Here i should have part of form with phones which is not rendering. 

     <input class="btn btn-large btn-warning" name="commit" type="submit" value="Change">
   </fieldset>
 </form>

我从来没有遇到过这么奇怪的问题。是bug还是什么？是我的错吗？

【问题讨论】：

将此作为评论发布，因为我不完全确定。我认为这可能是因为当您创建 @ipupil 时，关系设置不正确。如果将@ipupil = Factory( :pupil, :pupil_phone => Factory( :pupil_phone )) 替换为：@ipupil = Factory(:pupil) 和Factory(:pupil_phone, :user => @ipupil)，测试是否通过？
@pjumble 你的建议对我不起作用，但你给了我如何解决这个问题的想法。此外，您的想法是绝对正确的 - 关系设置不正确。您可以发布我现在可以使用的代码，以便我尽可能多地感谢您吗？代码：before(:each) do @ipupil = FactoryGirl.create( :pupil ) @attr_pupil_phones = { :pupil_home_number => "8903111111", :pupil_mobile_number => "777-33-22" } @ipupil.create_pupil_phone( @attr_pupil_phones ) ... end

【解决方案1】：

我解决了这个问题。非常感谢注意到这个问题的 pjumble。问题是工厂没有正确设置关系。所以我把代码改成这样：

before(:each) do 
  @ipupil = FactoryGirl.create( :pupil ) 
  @attr_pupil_phones = { :pupil_home_number => "8903111111", 
                         :pupil_mobile_number => "777-33-22" } 
  @ipupil.create_pupil_phone( @attr_pupil_phones ) 
  ... 
end

现在可以了。
