Settings View Source Quick CRUD

We can define quickly a CRUD for a table using SurrealEx.HTTP.Table.

The configuration requires the following arguments:

• conn: a SurrealEx connector.
• table: CRUD Table

configuration-example

Configuration example

defmodule SurrealExTest.CRUDHttp.TableTest do
  use ExUnit.Case

  defmodule Conn do
    use SurrealEx.Conn
  end

  defmodule TableBook do
    use SurrealEx.HTTP.Table,
      conn: SurrealExTest.CRUDHttp.TableTest.Conn,
      table: "book"

      # It will allow you use the following methods:
      #
      # get(id) 
      # create(obj)
      # put(id, obj)
      # update(id, obj)
      # delete(id)
      
  end
