我有一個Training模型嵌套在deviseUser模型下。視圖的測試表明'沒有路由匹配'的嵌套資源
/config/routes.rb
devise_for :users, path: 'u'
resources :users, only: ['index','show'], shallow: true do
resources :trainings
end
>耙路由

測試的觀點，當我具有以下輸出：

我將不會發布所有測試d所有佈局文件，因爲它會變得太大。相反，我會爲一個視圖發佈測試和佈局文件，並嘗試將修正擴展到其他視圖。
爲training#index測試是
/spec/views/trainings/index.html.erb_spec.rb
require 'spec_helper'
describe "trainings/index" do
before(:each) do
assign(:trainings, [
stub_model(Training,
:user_id => 1,
:training => "MyText"
),
stub_model(Training,
:user_id => 1,
:training => "MyText"
)
])
end
it "renders a list of trainings" do
render
# Run the generator again with the --webrat flag if you want to use webrat matchers
assert_select "tr>td", :text => 1.to_s, :count => 2
assert_select "tr>td", :text => "MyText".to_s, :count => 2
end
end
/app/views/index.html.rb
<h1>Listing trainings</h1>
<table>
<tr>
<th>User</th>
<th>Training</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @trainings.each do |training| %>
<tr>
<td><%= training.user_id %></td>
<td><%= training.training %></td>
<td><%= link_to 'Show', training %></td>
<td><%= link_to 'Edit', edit_training_path(training) %></td>
<td><%= link_to 'Destroy', training, confirm: 'Are you sure?', method: :delete %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Training', new_user_training_path(@user) %>
它表示路線不匹配，但他們在那裏。爲什麼會發生？！
