Refactoring Helper Methods: Part 1

• refactoring routes

get "/", controller: "movies", action: "index"

• more shorthand syntax for a route

get "/" => "movies#index"

• we can shorten this even further for the root because there is only 1 path:

root "movies#index"

• "rails routes" command shows all defined routes

• we can name routes with "as:"

get "/movies/:id" => "movies#show", as: :details

• we can then access this specific route with an argument:

details_path(42) --> "/movies/42"

• Using route names reduces redundancy when updating URL names! Always refer to URLs using route names from now on

---

• We can truncate @a_movie.id to @a_movie when using movie_path

• on View templates, we should use paths (movie_path)

• on Server side, we should use URLs (movie_url)

• When possible, remove render statements if class and definition matches

• Replace:
  .
