Waffle.Ecto.Definition (waffle_ecto v0.0.12)

Provides a set of functions to ease integration with Waffle and Ecto.

In particular:

  • Definition of a custom Ecto Type responsible for storing the images
  • URL generation with a cache-busting timestamp query parameter

example

 Example 

defmodule MyApp.Uploaders.AvatarUploader do
  use Waffle.Definition
  use Waffle.Ecto.Definition

  # ...
end

url-generation

 URL generation

Both public and signed urls will include the timestamp for cache busting, and are retrieved the exact same way as using Waffle directly.
