【问题描述】：

我想获取一天和一周内加入的用户总数，我尝试如下

member_in_day = User.objects.exclude(is_staff=True)\
    .annotate(day=TruncDay('date_joined')).values('date_joined') \
    .annotate(total_members=Count('date_joined')) \
    .order_by('-date_joined')
member_in_week = User.objects.exclude(is_staff=True)\
    .annotate(week=TruncWeek('date_joined')).values('date_joined') \
    .annotate(total_members=Count('date_joined')) \
    .order_by('-date_joined')

模型是用户，我得到的输出对于两个查询都是相同的，而不是一天它也给其他查询集。如何将今天的总数和本周的总数作为模板

<QuerySet [{'date_joined': datetime.datetime(2020, 12, 28, 16, 47, 40, 509134, tzinfo=<UTC>), 'total_members': 1}, {'date_joined': datetime.datetime(2020, 12, 23, 11, 8, 19, 241355, tzinfo=<UTC>), 'total_members': 1}, {'date_joined': datetime.datetime(2020, 12, 23, 11, 6, 14, 20673, tzinfo=<UTC>), 'total_members': 1}, {'date_joined': datetime.datetime(2020, 12, 22, 9, 25, 45, 14632, tzinfo=<UTC>), 'total_members': 1}, {'date_joined': datetime.datetime(2020, 12, 22, 9, 24, 25, 819750, tzinfo=<UTC>), 'total_members': 1}, {'date_joined': datetime.datetime(2020, 12, 20, 12, 7, 37, 59113, tzinfo=<UTC>), 'total_members': 1}]> members

【解决方案1】：

你不应该使用date_joined，而是在你截断之后使用day或week，所以：

member_in_day = User.objects.exclude(is_staff=True).values(
    day=TruncDay('date_joined')
).annotate(
    total_members=Count('date_joined')
).order_by('-day')

同members_in_week:

member_in_week = User.objects.exclude(is_staff=True).values(
    week=TruncWeek('date_joined')
).annotate(
    total_members=Count('date_joined')
).order_by('-week')

@Biju：你不：模板应该不关心业务逻辑，只关心渲染逻辑上，您应该在视图中执行此操作，并将其传递给模板。
), 'total_members': 1}, {'week': datetime .datetime(2020, 12, 21, 0, 0, tzinfo=), 'total_members': 4}, {'week': datetime.datetime(2020, 12, 14, 0, 0, tzinfo=), 'total_members': 1}]> 成员
), 'total_members': 1}, {'day': datetime .datetime(2020, 12, 23, 0, 0, tzinfo=), 'total_members': 2}, {'day': datetime.datetime(2020, 12, 22, 0, 0, tzinfo= >), 'total_members': 2}, {'day': datetime.datetime(2020, 12, 20, 0, 0, tzinfo=), 'total_members': 1}]> 成员
这是当前输出
@Biju：你可以遍历查询集，比如{% for item in myqs %}{{ item.week }}: {{item.total_members }}{% endfor %}。
