How to generate Time based One Time Password(OTP) with Django
I am generating a random string as OTP using the following code - from django.utils.crypto import get_random_string otp = get_random_string(6, allowed_chars='0123456789') The problem with this is due to SMS delivery issues people request for a lot of OTPs and then when they arrive together they have no idea which one is currently valid.

override __str__(self) of a model from an imported app
I'm facing the following situation: I have a django project, which uses an outside app [App1]. Within App1, it has the following structure: abstract class 'Base': class Base(models.Model): """ Base model with boilerplate for all models. """ name = models.CharField(max_length=200, db_index=True) alternate_names = models.TextField(null=True, blank=True, default='') .............. .............. class Meta: abstract = True def __str__(self): display_name = getattr(self, 'display_name', None) if display_name: return display_name return self.name abstract class based on 'Base', called 'AbstractClassA': class AbstractClassA(Base): display_name = models.CharField(max_length=200) .... .... class Meta(Base.Meta): abstract = True def get_display_name(self): .... .... return .... The non abstract class class ClassA(AbstractClassA) Now, when I do a query in my view for this ClassA, for example: qs = ClassA.objects.filter(Q(name__icontains=query_term)....) return qs I feed this qs into another outside app (autocomplete), so that when I type in 'xxxx' on my web form, the form would give me suggestions on available matches in the DB, based on this qs. This all works great, the only thing is, the list of potential matches shown to me is the default representation of the ClassA objects, which I traced back to def __str__(self): display_name = getattr(self, 'display_name', None) if display_name: return display_name return self.name defined in the base abstract model … -

Djanog extract field form html
I have a html page that returns data in a form. The forms is a multiple choice checkbox field with "name=states1". When I run print(vars(self)) in my forms.py I see that the data is there ['MD', 'WV', 'WY'] (see below) however, when I try to extract it with print(self.data['states1']) I just get 'WY' and print(len(self.data['states1'])) returns 2. {'instance': <AA: AAobject>, '_validate_unique': False, 'is_bound': True, 'data': <QueryDict: {'csrfmiddlewaretoken': ['AAAAA']: ['1'], 'states1': ['MD', 'WV', 'WY'], 'states': [''], 'price': ['2.00'], 'user': ['1', '1']}>, ...
