Overriding depth in Django models

Question

From this question I had the idea to redefine depth in my Django models. I took a snippet of code from this question and put it in my model with the following signature:

def __deepcopy__(self, *args, **kwargs):

However, I want to be able to pass the parameters "field" and "value", but this does not work. When I call:

deepcopy(s1, field='foo',value='bar')

with parameters trying to extract from the method body using kwargs ['field'] and kwargs ['value'], I get the following error:

File "<stdin>", line 1, in <module>
TypeError: deepcopy() got an unexpected keyword argument 'field'

By the way, I assume that I need to import the deepcopy method to use it in general, which I do with:

from copy import deepcopy

There is some mistake in my understanding, thanks in advance for the explanation.
