对于嵌套资源控制器规范 - Rails，Rspec，“无路由匹配”错误

Question

我为嵌套资源No route matches操作一直收到#create错误。这是我得到的：

路线：

...
resources :users, only: [:show, :create] do 
  resources :filters, only: [:new,:create]
end
...

控制器规范：

...
context 'with valid attributes' do 
  it "creates new Filter" do
    expect{
    post :create, {:filter => attributes_for(:filter)}
    }.to change(Filter, :count).by(1)
  end
...

错误：

No route matches {:action=>"create", :controller=>"filters", :filter=>{[long filter hash]}

Answer 1

因为它是嵌套的，所以还需要包含过滤器所属的父对象的ID。

post :create, user_id: <some_user_id>, {:filter => attributes_for(:filter)}
