title: Getting actual data of model
body: <p>Suppose I've some model already and after some time I'll changing some field of this model in another function.</p>
  
  <p>Is there any nice way to get the actual data(state) of the model from DB without using standard '<code>MyRepo.get(MyModel, model.id)</code>' ?</p>
  
  <pre><code>case MyModel.create(attr) do
    {:ok, model} -&gt;
      ...some code...
      # here model will update
      Task.start(fn -&gt; Model.do_some(model) end)
      # here I need model with actual data from DB
      {:reply, {:ok, ModelView.render("show.json", model: model)}, socket}
    {:error, message} -&gt;
      ...some code...
  end
  </code></pre>
  
  <p>P.s. the model can have some preloaded association</p>
