Railsのscaffoldと同じことがPhoenixでもできるっぽい。

とりあえずmix phoenix.gen.htmlでいけるっぽい

zsh

$ mix phoenix.gen.html User users name:string email:string bio:string number_of_pets:integer

Add the resource to the proper scope in web/router.ex:

    resources "/users", UserController

and then update your repository by running migrations:

    $ mix ecto.migrate

指示されているとおりにする。

まずは config/router.ex に追加する。

config/router.ex

defmodule HelloPhoenix.Router do
  use HelloPhoenix.Web, :router
  
  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_flash
    plug :protect_from_forgery
  end

   pipeline :api do
     plug :accepts, ["json"]
   end

   scope "/", HelloPhoenix do
     pipe_through :browser # Use the default browser stack

     get "/", PageController, :index
     # ここらに突っ込む
     resources "/users", UserController
   end

   # Other scopes may use custom stacks.
   # scope "/api", HelloPhoenix do
   #   pipe_through :api
   # end
 end

userテーブル作るためにmigrateする。

zsh

$ mix ecto.migrate                                                                                                                 
[info] == Running HelloPhoenix.Repo.Migrations.CreateUser.change/0 forward
[info] create table users
[info] == Migrated in 0.1s

結果

http://localhost:4000/users
