EctoMorph

EctoMorph morphs your Ecto capabilities into the s t r a t o s p h e r e !

Usually you have to do something like this:

defmodule Embed do
  use Ecto.Schema

  embedded_schema do
    field(:bar, :string)
  end
end

defmodule Test do
  use Ecto.Schema

  embedded_schema do
    field(:thing, :string)
    embeds_one(:embed, Embed)
  end

Ecto.Changeset.cast(%Test{}, %{"thing" => "foo", "embed" => %{"bar"=> "baz"}}, [:thing])
|> Ecto.Changeset.cast_embed(:embed)

Now we can do this:

EctoMorph.to_struct(%{"thing" => "foo", "embed" => %{"bar"=> "baz"}}, Test)

Or something like this:

with {:ok, %{status: 200, body: body}} <- HTTPoison.get("mygreatapi.co.uk") do
  Jason.decode!(body)
  |> EctoMorph.to_struct(User)
end
