Overview of this book

This book is intended for users with some knowledge of the Elixir language syntax and basic data types/structures. Although this is a cookbook and no sequential reading is required, the book’s structure will allow less advanced users who follow it to be gradually exposed to some of Elixir’s features and concepts specific to functional programming. To get the most out of this book, you need to be well versed with Erlang.

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       Todo.TodosController.new/2
todos_path  GET     /todos/:id       Todo.TodosController.show/2
todos_path  POST    /todos           Todo.TodosController.create/2
todos_path  PATCH   /todos/:id       Todo.TodosController.update/2
   ...
