Storage.Attachment (PhoenixContribStorage v0.1.0)

Provides macros for adding file attachments to Ecto schemas.

This module allows you to easily add file attachment functionality to your Ecto schemas, similar to Rails ActiveStorage.

Usage

defmodule MyApp.User do
  use Ecto.Schema
  use Storage.Attachment

  schema "users" do
    field :name, :string
    has_one_attached :avatar
    has_many_attached :documents
  end
end

This will add virtual fields and helper functions for managing attachments.
