class MyModelForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(MyModelForm, self).__init__(*args, **kwargs)
self.initial['some_field'] = some_encoding_method(self.instance.some_field)
class MyModelAdmin(admin.ModelAdmin):
form = MyModelForm
...
Where, some_encoding_method
would be something you’ve set up to determine the spacing/indentation or some other 3rd-party functionality you’re borrowing on. However, if you write your own method, it would be better to put it on the model, itself, and then call it through the instance:
class MyModel(models.Model):
...
def encode_some_field(self):
# do something with self.some_field
return encoded_some_field
Then:
self.instance.encode_some_field()
