Phoenix 1.6 Accounts & Users

Every web application is organized around users: admins and end-users and other roles.

I like to create a document for every time I design a context and schemas.

# Users

mix phx.gen.html Accounts User users \
    username:string \
    first_name:string \
    last_name:string \
    slug:string \
    email:string \
    bio:text \
    location:string \
    website:string \
    profile_image:string \
    banner_image:string \
    tagline:string \
    snowflake:string \
    admin:boolean \
    editor:boolean \
    host:boolean \
    seller:boolean

This makes a documentary record of the code that is created by generators. After running above we get a migration which I now change to add a CITEXT extension for case insensitive email etc.

defmodule Folkbot.Repo.Migrations.CreateUsers do
  use Ecto.Migration

  def change do
    execute "CREATE EXTENSION IF NOT EXISTS citext"
    create table(:users) do
      add :username, :citext, null: false
      add :first_name, :citext
      add :last_name, :citext
      add :slug, :string
      add :email, :citext, null: false
      add :bio, :text
      add :location, :string
      add :website, :string
      add :profile_image, :string
      add :banner_image, :string
      add :tagline, :string
      add :snowflake, :string
      add :admin, :boolean, default: false, null: false
      add :editor, :boolean, default: false, null: false
      add :host, :boolean, default: false, null: false
      add :seller, :boolean, default: false, null: false

      timestamps()
    end
  end
end

We now have a working route for users and a schema.

defmodule Folkbot.Accounts.User do
  use Ecto.Schema
  import Ecto.Changeset

  schema "users" do
    field :admin, :boolean, default: false
    field :banner_image, :string
    field :bio, :string
    field :editor, :boolean, default: false
    field :email, :string
    field :first_name, :string
    field :host, :boolean, default: false
    field :last_name, :string
    field :location, :string
    field :profile_image, :string
    field :seller, :boolean, default: false
    field :slug, :string
    field :snowflake, :string
    field :tagline, :string
    field :username, :string
    field :website, :string

    timestamps()
  end

  @doc false
  def changeset(user, attrs) do
    user
    |> cast(attrs, [:username, :first_name, :last_name, :slug, :email, :bio, :location, :website, :profile_image, :banner_image, :tagline, :snowflake, :admin, :editor, :host, :seller])
    |> validate_required([:username, :first_name, :last_name, :slug, :email, :bio, :location, :website, :profile_image, :banner_image, :tagline, :snowflake, :admin, :editor, :host, :seller])
  end
end

Notice also I added a Snowflake ID field and that will be the next post.

I've skipped the steps from the Phoenix framework docs.
