我的模型看起来像这样:
Person(model.Models):
name = model.CharField(max_length=32)
date_added = models.DateTimeField(auto_now_add=True)
Note(model.Models):
person = model.ForeignKey(Person)
action = model.CharField(max_length=32, default='call)
date_added = models.DateTimeField(auto_now_add=True)
owner = model.ForeignKey(User)
我的观点:
def get_working_persons(self):
relevant_actions = ['call', 'meeting', ...]
query = Q(action__in=relevant_note_actions) | Q(date_added__range=[fourteen_days_ago, now])
get_current_person_notes = Note.objects.filter(query).exclude(~Q(owner=request.user)).values('owner', 'action', 'person')
这将返回一个笔记列表,其中每个人都列出了所有笔记,这些笔记都发布在date_added__范围内。如何获得该日期范围内符合其他标准的每个人的最后一个注释?

将返回查询集的顶级对象 或
Note.objects.filter(query).exclude(~Q(owner=request.user)).values('owner', 'action', 'person').first()
将返回查询集的最后一个对象
或最新的字段名称
Note.objects.filter(query).exclude(~Q(owner=request.user)).values('owner', 'action', 'person').last()
