Documentation and help with i18n

[goravbhootra]

Hi @liveforeverx,

Thank you for the fantastic library and amazing implementation of Dlex.Node. I am working on developing a LMS prototype - my first attempt at using a Graph database. I had to dig into Dlex code to understand the implementation. I intend to add documentation and may be a sample repo for anybody else wanting to use the library. I have done the following:

• Implemented a Grepo module similar to Repo.ex for making calls to Dgraph. I may be using postgres in the project as well and hence, retained Repo for the purpose.
• added Grepo to supervision tree.
• implemented a the model (Course.ex) using Dlex.Node and the context (Courses.ex).
• got CRUD action to work with a html view.
• i18n feature in model - this is where I need help at the moment.
• define associations in the models - needs update in Dlex for supporting [:uid] added in Dgraph v 1.1
• define unique constraints on fields.

defmodule Lms.Courses.Course do
  use Dlex.Node
  @derive {Phoenix.Param, key: :uid}

  import Ecto.Changeset

  schema "courses" do
    field(:title, :string, index: ["term"])
    field(:description, :string)
    field(:duration_allowed, :integer)
   ...

how do I use title@en or other locales in this context?

any pointers to the pending items would be great help.

Best,
Gorav
