HTTP action naming (ARCH6004)

Key ruby.naming.controller-action-naming · Severity info · Category naming

For RESTful consistency, controller action names should match the semantics of the HTTP verb they handle. GET requests should map to index/show, POST to create; names that contradict the verb (a create on a GET) mislead readers.

Incorrect

class ArticlesController < ApplicationController
  # GET /articles
  def create_list
    @articles = Article.all
  end
end

Correct

class ArticlesController < ApplicationController
  # GET /articles
  def index
    @articles = Article.all
  end
end

Fix

Rename the action to the RESTful name that matches its HTTP verb (GET→index/show, POST→create).
