Hi, Thanks you very much for the informative answer! It clears all the questions I had in my mind. Because I have some idea to build a tool to draw the model (UML) --> Generate Django Model code --> and then we can deploy it to db. Moreover I was thinking that if it possible to customize (edit existing methods, add new methods..) the generated database api it would be good.
