问题 I'm working my way through the django tutorial for version 1.8 and I am getting an error that I am stuck on and can't seem to figure out.

Hourly grouping of rows using Django

由 别等时光非礼了梦想. 提交于 2019-12-07 23:19:10
问题 I have been trying to group the results of table into Hourly format using DateTimeField . SQL: SELECT strftime('%H', created_on), count(*) FROM users_test GROUP BY strftime('%H', created_on); This query works fine, but the corresponding Django query does not. Django queries I've tried: Test.objects.extra({'hour': 'strftime("%%H", created_on)'}).values('hour').annotate(count=Count('id')) # SELECT (strftime("%H", created_on)) AS "hour", COUNT("users_test"."id") AS "count" FROM "users_test"

Django DurationField default

Ok. Maybe we should pass integer? pause = DurationField(default=int(timedelta(minutes=20).total_seconds())) or: pause =

Django 1.8 and MongoDB?

由 只愿长相守 提交于 2019-12-07 09:11:43
问题 This question is already asked on StackOverflow, The asked questions date back to 2013, Its 2015 now and Django has grown up fast. What is the situation of using mongodb with Django 1.8 as of 2015? Does Django support Monogodb out of the box (with db adapters)? or another distribution like django-nonrel should be used? 回答1: just my thoughts and somewhat subjective and opinionated but I would say it does not work very well. I quickly disbanded the idea of trying to run Django with MongoDB,
