Question

Rails 3.1.0 Rspec 2

在嵌套资源的视图规范中，我是否需要实例化/ stub 存根嵌套资源之前的父资源？

我问这个是因为我的所有观看规范都失败了我在我的应用程序中介绍的嵌套资源。嵌套资源按预期工作当我手动测试它虽然:( 这是我的编辑视图规范的样子。

----- "./spec/views/sub_categories/edit.html.erb_spec.rb" - start -------- 


require 'spec_helper'  describe "sub_categories/edit.html.erb" do    before(:each) do 
    @sub_category = assign(:sub_category, stub_model(SubCategory, 
      :name => 'International interest rates', 
      :description => 'Comprehensive rates covering Australia, NZ,  Malaysia and Singapore', 
      :category_id => 3, 
      :created_by => 1, 
      :updated_by => 1 
    ))    end    it "renders the edit sub category form" do 
    render 
    # Run the generator again with the --webrat flag if you want to  use webrat matchers 
    assert_select "form", :action =>  category_sub_categories(@sub_category), :method => "post" do 
      assert_select "input#sub_category_name", :name =>  "sub_category[name]" 
      assert_select "textarea#sub_category_description", :name =>  "sub_category[description]" 
    end    end  end 
--- "./spec/views/sub_categories/edit.html.erb_spec.rb" - end --------

以下是失败的摘录：

----------- extract start ------------------------- 

  1) sub_categories/edit.html.erb renders the edit sub category form 
     Failure/Error: render 
     ActionView::Template::Error: 
       undefined method `sub_category_path' for #<#<Class:  0x0000010127d2b8>:0x000001016e2380> 
     # ./app/views/sub_categories/_form.html.erb:1:in  `_app_views_sub_categories__form_html_erb__4092631658606598204_2155519360'

     # ./app/views/sub_categories/edit.html.erb:3:in  `_app_views_sub_categories_edit_html_erb___3853358586184509671_2155544160'

     # ./spec/views/sub_categories/edit.html.erb_spec.rb:15:in `block  (2 levels) in <top (required)>' 
----------- extract end -------------------------

这是我的表格部分看起来像

----- app/views/sub_categories/_form.html.erb start --------------------- 

<%= form_for [@category, @sub_category] do |f| %>    <% if @sub_category.errors.any? %> 
    <div id="error_explanation"> 
      <h2><%= pluralize(@sub_category.errors.count, "error") %>  prohibited this sub_category from being saved:</h2> 
      <ul> 
      <% @sub_category.errors.full_messages.each do |msg| %> 
        <li><%= msg %></li> 
      <% end %> 
      </ul> 
    </div>    <% end %>    <div class="field"> 
    <%= f.label :name %><br /> 
    <%= f.text_field :name %>    </div>    <div class="field"> 
    <%= f.label :description %><br /> 
    <%= f.text_area :description %>    </div>    <div class="actions"> 
    <%= f.submit %>    </div>  <% end %> 

----- app/views/sub_categories/_form.html.erb end ---------------------

这是我在运行'rake routes'时看到的内容：

------- routes start ---------------------------     category_sub_categories GET    /categories/:category_id/  sub_categories(.:format)  {:action=>"index", :controller=>"sub_categories"} 
                           POST   /categories/:category_id/  sub_categories(.:format)  {:action=>"create", :controller=>"sub_categories"}   new_category_sub_category GET    /categories/:category_id/  sub_categories/new(.:format)  {:action=>"new", :controller=>"sub_categories"}  edit_category_sub_category GET    /categories/:category_id/  sub_categories/:id/edit(.:format)  {:action=>"edit", :controller=>"sub_categories"} 
     category_sub_category GET    /categories/:category_id/  sub_categories/:id(.:format)  {:action=>"show", :controller=>"sub_categories"} 
                           PUT    /categories/:category_id/  sub_categories/:id(.:format)  {:action=>"update", :controller=>"sub_categories"} 
                           DELETE /categories/:category_id/  sub_categories/:id(.:format)  {:action=>"destroy", :controller=>"sub_categories"} 
                categories GET    /  categories(.:format)  {:action=>"index", :controller=>"categories"} 
                           POST   /  categories(.:format)  {:action=>"create", :controller=>"categories"} 
              new_category GET    /categories/  new(.:format)  {:action=>"new", :controller=>"categories"} 
             edit_category GET    /categories/:id/  edit(.:format)  {:action=>"edit", :controller=>"categories"} 
                  category GET    /  categories/:id(.:format)  {:action=>"show", :controller=>"categories"} 
                           PUT    /  categories/:id(.:format)  {:action=>"update", :controller=>"categories"} 
                           DELETE /  categories/:id(.:format)  {:action=>"destroy", :controller=>"categories"} 
                      root        / 
------- routes end ---------------------------

表单partial已正确配置父资源和嵌套资源（即“form_for [@category, @sub_category]”）。它似乎正在调用我拥有的路径sub_category_path 从未指定。

当要创建编辑/创建表单时，会出现错误形式部分被称为。

我真的很困惑为什么会这样，并咨询过搜索结果我通过谷歌搜索'嵌套资源与rspec'， Yehuda Katz的“Rails in Action 3”和Rspec书:(

如果有人知道我错过了什么，我很想听听你的想法。

Answer 1

category_id位于@sub_category.category_id，而不在@category中，您在视图中使用（现在为零）。

[@category, @sub_category]只是url_for([@category, @sub_category])的一个快捷方式，如果参数为零，则返回单个资源路径。

检查guide。

嵌套资源视图规范似乎指的是不存在的路由
