Comment (by yoongkang):
Yep. I have a pull request on GitHub, but basically the method should take
a dictionary where the keys are the names of the field, and the values are
the updated field values.
This code snippet should do the trick:
{{{
def assign_attributes(self, values_dict):
keys = values_dict.keys()
fields = [f.name for f in self._meta.get_fields()]
for k in keys:
if k in fields:
setattr(self, k, values_dict[k])
}}}
There is a similar method in Rails which I'm used to using:
