Create slugs from Ecto fields automatically

Install https://github.com/sobolevn/ecto_autoslug_field
Then:

defmodule NameSlug do
 use EctoAutoslugField.Slug, from: :name, to: :slug
end

defmodule User do
 use Ecto.Schema
 import Ecto.Changeset

 schema "users" do
 field :name, :string
 field :slug, NameSlug.Type
 end

 @required_fields ~w(name)
 @optional_fields ~w(slug)

 def changeset(model, params \\ :empty) do
 model
 |> cast(params, @required_fields, @optional_fields)
 |> NameSlug.maybe_generate_slug
 |> NameSlug.unique_constraint
 end
end
