I think it could be good to add resolver tests for this.

Since it's a library that depends on Ecto, this is acceptable, but it's possible that it could have a different behaviour since we're not actually firing any query explicitly here. (Related to #1)

It could be possible to not have to use an additional use_loader? option if permit_phoenix/controller.ex allows differentiating between nil and a function at plug level. (line 365)


with {_, true} <-
{:pre_auth, authorized?(subject, authorization_module, resource_module, action)},
resource <- meta[:loader].(params_for_loader),

If in permit_phoenix the loader/1 function is defined as such:

def loader(resolution_context) do
  case unquote(opts)[:loader] do
    nil -> nil
    loader -> {:loader, unquote(__MODULE__).loader(resolution_context, unquote(opts))}
  end
end

you could check here whether loader was not given at all, or it returned nil
