How to access current module in Elixir

Question

Let's say I have a module MyApp.User and it has the following method:

def update_some_counter(user) do
  from(u in MyApp.User , where: u.id == ^user.id)
  |> Repo.update_all(inc: [some_counter: 1])
end

Is there a way to change MyApp.User in the code above to some method that retrieves current module?

Answer 1

Patrick's answer is correct: you can use __MODULE__. However, I would advise all of your query functions in the model to receive the query as argument (see here: http://blog.drewolson.org/composable-queries-ecto/) and to not call the repository inside your model.

Leave the act of calling the repository, which is a side-effect, to the integration layer, like controllers and what not.

Answer 2

You can use __MODULE__, which will be replaced with the name of the enclosing module at compile time.
