Creating a controller

In Phoenix, controllers are Elixir modules that define functions (or actions) to handle the requests dispatched by the router. The controllers are responsible for preparing and passing data to the view layer and determining the rendering of these views.

Getting ready

To get started, we will extend the project defined in the Defining routes recipe. The defined routes are as follows:

 page_path  GET     /                Todo.PageController.index/2
   my_path  GET     /text            Todo.MyController.plaintext/2
   my_path  GET     /generated       Todo.MyController.send_html/2
todos_path  GET     /todos           Todo.TodosController.index/2
todos_path  GET     /todos/:id/edit  Todo.TodosController.edit/2
todos_path  GET     /todos/new
todos_path  GET     /todos/:id
todos_path  POST    /todos           Todo.TodosController.create/2
todos_path  PATCH   /todos/:id       Todo.TodosController.update/2
