How to override field value display in Django admin change form
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_fieldThen:
self.instance.encode_some_field()
