When saving, how can you check if a field has changed?

Question

In my model I have :

class Alias(MyBaseModel):
    remote_image = models.URLField(max_length=500, null=True, help_text=\"A URL that is downloaded and cached          


        

Answer 1

This works for me in Django 1.8

def clean(self):
    if self.cleaned_data['name'] != self.initial['name']:
        # Do something
