AarhusElixir

Hands on Phoenix app for AarhusElixir meetup: I asume you got postgres installed.

Get the stack up running

$ brew install erlang
$ brew install elixir
$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phoenix_new.ez

Create a new app

$ mix phoenix.new aarhus_elixir
$ say yes [Y]
read text in console

Configure DB

open project in your favorite editor
edit file config/dev.exs line 38 and 39 (database name and username)
create your database with ` $ mix ecto.create

Fire up the server

$ mix phoenix.server
open http://localhost:4000 in your favorite browser
reload page and read text in console. fast huh?

Diving in

Now the stack is up runing it's time to get our hands dirty

documentation for scaffolding found on https://hexdocs.pm/phoenix/Mix.Tasks.Phoenix.Gen.Html.html
scaffold a user $ mix phoenix.gen.html User users name:string email:string password_hash:string
read test in console
migrate the database $ mix ecto.migrate
Test the app $ mix test
open: web/router
paste in on line: 20: resources "/users", UserController
change root to users/
$ mix ecto.migrate
restart server $ mix phoenix.server
visit http://localhhost:3000

huray we got a user

Lets look around

quick walk through folders and files
open web/models/user.exs: look at schema
open web controllers/user_controller.exs
think about views vs templates
endpoints and router.ex

A dash of debugging

why not inspect with some nice markup

open mix.exs
add {:apex, "~>0.3.5"}, on line 40
stop server
$ mix deps.get
start server

web/models/user.exs add Apex.ap params on line 20 create a user watch terminal remove web/controllers/user_controller.ex line 20: add Apex.ap changeset create user create a user watch terminal

open user model add to schema field :password, :string, virtual: true field :password_confirmation, :string, virtual: true

Prepare the user for authorization

Install dependencies with mix deps.get
Create and migrate your database with mix ecto.create && mix ecto.migrate
