Data Access Object - dao

Dao is a recreation of the B.E.E (back end enginee) in elixir.

The idea is to compose organic queries that self describe the reponse structure of the data from a database

How it works

• Compose a query using maps

query = %{
  students: %{
    class_room: %{},
    _w: { :name, :contains_ignore_case,  "mike" }
  }
}

• Pass the query to a dao function

results = Dao.get(query)

• Internally the query is converted into an sql statement

SELECT school_app.students.name as mdmd FROM `school_app.students` LEFT JOIN kkffl to gkgk WHERE `school_app.students.name` like '%mike%'

• The query is executed and the results are formated according to the structure of the query

case results do
  {:ok, data } -> IO.inspect( data )
  {:error, errors } -> IO.inspect( errors )
end

• The data inspected above will be like this

%{
  students: [
    %{
      id: 1,
      name: "mike nyola",
      class_room_id: 5,
      class_room: %{
        id: 5,
        name: "grade 6"
      }
    },
    %{
      id: 5,
      name: "mike tyler",
      class_room_id: 5,
      class_room: %{
        id: 5,
        name: "grade 6"
      }
    }
  ]
}
