Django admin form override stop required validation
I have a Django model with the following two fields. period_from = models.DateField(verbose_name='From') period_to = models.DateField(verbose_name='To') I created a model form to do a custom validation as follows. class AdminBillForm(ModelForm): class Meta: model = Bill exclude = () def clean_period_from(self): period_from = self.cleaned_data.get('period_from') if (period_from >= timezone.now().date()): raise ValidationError("'From' date cannot be a future date.") return period_from def clean_period_to(self): period_to = self.cleaned_data.get('period_to') if (period_to > timezone.now().date()): raise ValidationError("'To' date cannot be a future date.") return period_to def clean(self): cleaned_data = super(AdminBillForm, self).clean() period_from = cleaned_data.get('period_from') period_to = cleaned_data.get('period_to') if (period_from >= period_to): raise ValidationError("'From' date should not be beyond 'To' date.") Then I registered this form in the admin. @admin.register(Bill) class BillAdmin(admin.ModelAdmin): form = AdminBillForm However if I left the period_from field empty it gives me following error. '>=' not supported between instances of 'NoneType' and 'datetime.date' When I remove the custom form it works perfectly saying that the period_from is a required field. -

How to filter Django model Multipoint objects which are located in an envelop?
I have following model: from django.contrib.gis.db import models class Foo(models.Model): # some other fields multipoint = models.MultiPointField() I am going to filter Foo instances based on the multipoint field and get all the instances that their line is located inside an envelop.

uWSGI server sometimes hung up for unknown reasons
Problem I've operated Django + uWSGI apps for a year on AWS, and it was working well until two weeks ago, but I run into the problem that the specific uWSGI process sometimes hung up and rarely recover automatically. Strangely enough, I'm always running three uWSGI servers on the same EC2 instance, but only the specific (most accessed) process always hung up, and the rest two uWSGI processes never hung up and continue to respond to HTTP requests even during the error. Even though they work on the same hardware and network, and are connected to same MySQL/Redis server. uWSGI dumped the following "OSError: write error" message during it was stuck, (but I think the message doesn't seem the useful information...)

How to specify GROUP BY field in Dajngo ORM?

Django validate DateTime
I have booking API endpoint and i want to check each time user want booking hall if DateTime and hall that user want booking is available. I try this queryset in validate in Serializer to check if this time and hall is booking or not def validate(self, data): BookingModel.objects.filter(date_time__exact=data['date_time']).get(hall_id__iexact=data['hall']).exists() but it give this Error: BookingModel matching query does not exist.
