I want this field to be saved encrypted in the db, but appear
unencrypted everywhere else:
class EncryptedCharField(models.CharField):
__metaclass__ = models.SubfieldBase
def save_form_data(self, instance, data):
setattr(instance, self.name, encrypt(data))
#def get_prep_value(self, value):
# return encrypt(data)
def value_from_object(self, obj):
return decrypt(getattr(obj, self.attname))
#def to_python(self, value):
# return decrypt(value)
class MyModel(models.Model):
secret = EncryptedCharField(max_length=100)
When this field is used in modelforms it works just fine: it is shown
with its decrypted length and saved encrypted. However when secret
is accessed, such as:
object = MyModel.objects.get()
