我的Training模型嵌套在devise User模型下。
/config/routes.rb
devise_for :users, path: 'u'
resources :users, only: ['index','show'], shallow: true do
resources :trainings
end

我不会发布所有测试和所有布局文件，因为它会变得太大。相反，我会为一个视图发布测试和布局文件，并尝试将更正扩展到其他视图。
training#index的测试是
/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) %>
它表明路线不匹配，但它们在那里。它为什么会发生？！
答案 0 :(得分：1)
您的索引视图有new_user_training_path(@user)，但您的索引规范未创建@user。就像您创建@trainings一样，您还需要在视图规范中创建@user，例如：
before(:each) do
assign(:user,
stub_model(User,
:id => 1
)
)
# ...
end
此外，通过将新视图从ActionView::Template::Error: undefined method 'trainings_path' for #<#<Class:...>>更改为form_for @training（嵌套）来修复form_for [@user, @training]错误。
