An OData v4 query parser and Ecto query builder.

Parses OData query strings or full URIs and returns Ecto.Query structs ready to execute against your own repo.

Configuration

Map OData entity names to your Ecto schema modules in config/config.exs:

config :ex_odata4, schemas: %{
  "Orders" => MyApp.Orders,
  "Products" => MyApp.Products
}

Usage

Parse a full OData URI:

ExOdata4.parse_uri("/Orders?\$filter=Amount gt 1000&\$top=25")
|> MyApp.Repo.all()

Or parse a query string directly when you already know the entity name:

ExOdata4.get("Orders", "\$filter=Status eq 'active'&\$top=10")
|> MyApp.Repo.all()

Both functions return an %Ecto.Query{} — execute it with whichever repo and database adapter your application uses.
