I know you can override the save() method in a model, but is it
possible to do it when you try to get a row or rows from a db? I have
data like this '\xFF\x00\x00\x00\xFE'... that I need to store in a
MySQL db.
When I was trying to save it I was getting an error. Now I override
the __save__ method and encode the data right before it's saved. This
works out fine, it's just that now I need to always code in the
decode('string-escape') every time I need to access the data. Is it
possible to override a method so when I use the A.objects.get /
filter / all methods it will automatically decode for me. Can I just
override a method like __get__ / __filter__ and just call the
superclass? I don't want to go down this road only to discover in a
couple of months that it's breaking something on the back end.
(How I'm doing it now )
class A(model):
encoded_data = models.TextField(max_length=4000)
def __save__(self):
encoded_data = self.encoded_data.encode('string-escape')
super(A, self).save(*args, **kwargs)
data = '\xFF\x00\x00\x00\xFE' #-- similar to this
aObject = A()
aObject.encoded_data = data
aObject.save()
anotherObject = A.objects.get(id=1)
decoded_data = anotherObject.encoded_data
decoded_data = decoded.data.decode('string-escape')
