The third line above is
post '/movies' => 'movies#create', :as => 'movies'
Eight line all in resources 'movies'.
(One more is PATCH update(partial))
:as name should be singular when it applies to one resource, plural when it applies to the collection.
Rails route which is abstract, subtle different from concrete HTTP route(HTTP Method + URI).
Rails 的 route 是对 HTTP route 的抽象，是“匹配并分发”这一层的定义。 可以理解为：Rails route = HTTP route 模式 + 控制器映射。
The Root Route
An Example
The way controller renders a view is that rails will automatically find the corresponding view file and analyze, run all pre-processor needed (haml→html in this case) and eventually convert it into HTML, JSON etc that browser can handle with and then return.
Route Helper Functions
as: xxx
Then xxx_path will be evaluated to a route that :as’s value is xxx.
