Adapter not working with Ecto 2.2.x

[FrancisMurillo]

Hello,

I followed the directions in setting up an Api.Repo. Everytime I use Api.Repo.all(Api.Tick), I get the following error

** (KeyError) key :fields not found in: %{prefix: nil, preloads: [], select: %{assocs: [], postprocess: {:from, :any, {:source, :from}}, preprocess: [{:source, {"ticks", Api.Tick}, [id: :binary_id, buy: :decimal, sell: :decimal, inserted_at: :naive_datetime, updated_at: :naive_datetime]}], take: []}, sources: {{"ticks", Api.Tick}}}
    (rethinkdb_ecto) lib/rethinkdb_ecto.ex:162: RethinkDB.Ecto.execute/6
    (ecto) lib/ecto/repo/queryable.ex:133: Ecto.Repo.Queryable.execute/5
    (ecto) lib/ecto/repo/queryable.ex:37: Ecto.Repo.Queryable.all/4

Any idea how to resolve this would be great.

Can you give the version of Ecto you are using.

[FrancisMurillo]

@redrabbit My ecto version is 2.2.6.

Some changes between Ecto 2.1.x and 2.2.x break things for the RethinkDB adapter. I'm investigating this. Meanwhile, you could use Ecto 2.1.

Any news on this?

@renews, I did not find time to come with a fix for this. I will give it a try once I have a little spare time. Any kind of help (investigations, code-review, PRs) is very welcome.
