Djangoでの毎日の新規ユーザー数のリストの作成

Question

日々のユーザー登録数のリストを作成したいと思います。以下は私がこれをやっている方法ですが、最も論理的な方法ですか？日の範囲については

daily_users = User.objects.filter(date_joined__day=datetime.today().day).count() 

：一日のために

users = User.objects.all() 
oldest_user_date = users.order_by('date_joined')[0].date_joined 
day_difference = (datetime.now() - oldest_user_date).days 

historical_user_signups_per_day = [] 
while day_difference > 0: 
    days_user_signups = users.filter(date_joined__gt=datetime.now()-timedelta(days=day_difference+1), date_joined__lt=datetime.now()-timedelta(days=day_difference)).count() 
    daily_count = { 
     'count': days_user_signups, 
     'date': datetime.now()-timedelta(days=day_difference) 
    } 
    historical_user_signups_per_day.append(daily_count) 
    day_difference -= 1 

Answer 1

users = User.objects.all() 
count_by_day = [{'count':users.filter(date_joined__day=x.day).count(), \ 
       'date':x} \ 
        for x in User.objects.dates('date_joined','days')] 

Answer 2

当日の新しいユーザー数を見つけるために：これは素晴らしいです

def get_curr_day_new_user_count(): 
    from datetime import date 
    from django.contrib.auth.models import User 

    today = date.today() 
    return User.objects.filter(date_joined__contains=today).count()
