Rails Rspec APIs Testing Notes

Folders Structure

  spec
  |--- apis #do not put into controllers folder. 
        |--- your_api_test_spec.rb  
  |--- controllers
  |--- models
  |--- factories
 |--- views

При выполнении сложных запросов, часто бывает необходимо выполнить предзагрузку данных об ассоциациях какой либо модели. Обычно сложные запросы выполняються через find_by_sql, например

Post.find_by_sql "SELECT p.name, c.author FROM posts p, comments c WHERE p.id = c.post_id"
> [#<Post:0x36bff9c @attributes={"title"=>"Ruby Meetup", "first_name"=>"Quentin"}>, ...]

Чтобы при вывзове ассоциаций объектов избежать проблемы с select(n+1) запросами в Rails существует eager-loading, например:

	// in 2020 actual $sizes: ("xs":320px, "sm":576px, "md":768px, "lg":992px, "xl":1200px);
	/* Extra small devices (phones, 600px and down) */
	@media only screen and (max-width: 600px) {...}

	/* Small devices (portrait tablets and large phones, 600px and up) */
	@media only screen and (min-width: 600px) {...}

	/* Medium devices (landscape tablets, 768px and up) */
	@media only screen and (min-width: 768px) {...}
