railstutorial 10.3.1：未定義的局部變量或方法`microposts_path '`micropost_path'

Question

有在10.3.1 Access control與測試問題：

Failures: 

    1) Authentication authorization for non-signed-in users in the Microposts controller submitting to the destroy action 
Failure/Error: before { delete micropost_path(FactoryGirl.create(:micropost)) } 
NoMethodError: 
    undefined method `micropost_path' for #<RSpec::Core::ExampleGroup::Nested_3::Nested_3::Nested_1::Nested_3::Nested_2:0x00000004edd970> 
# ./spec/requests/authentication_pages_spec.rb:117:in `block (6 levels) in <top (required)>' 

    2) Authentication authorization for non-signed-in users in the Microposts controller submitting to the create action 
Failure/Error: before { post microposts_path } 
NameError: 
    undefined local variable or method `microposts_path' for #<RSpec::Core::ExampleGroup::Nested_3::Nested_3::Nested_1::Nested_3::Nested_1:0x0000000521c758> 
# ./spec/requests/authentication_pages_spec.rb:112:in `block (6 levels) in <top (required)>' 

我routes.rb這個附加：

resources :misroposts, only: [:create, :destroy] 

但不幫忙。什麼意思undefined method 'micropost_path'？我不知道該怎麼辦。

Answer 1

你是否在routes.rb有resources :microposts, only: [:create, :destroy]？檢查出Listing 10.22。

這將創建兩個命名路由，microposts_path（用POST要求訪問）和micropost_path，你可以看到（連同應用中的所有其他路徑），如果鍵入rake routes進（用DELETE要求訪問）安慰。

查看本教程的Table 7.1 - 這就是當您將resources :users添加到routes.rb時發生的情況。

Resources :microposts, only: [:create, :destroy]會的工作方式相同，不同之處，當然，你只會得到create和destroy行動，在Table 10.2解釋。
