Django模型查询中的OR运算符

Question

我正在尝试OR在Django filter()函数中使用运算符.现在我有

contactlist = Contact.objects.filter(last_name__icontains=request.POST['query'])

但我也想用名字搜索.例如:

contactlist = Contact.objects.filter(last_name__icontains=request.POST['query'] OR first_name__icontains=request.POST['query'])

有谁知道如何做到这一点？

Answer 1

Q对象

from django.db.models import Q

Contact.objects.filter(Q(last_name__icontains=request.POST['query']) | 
                               Q(first_name__icontains=request.POST['query']))

Answer 2

result = Contact.objects.filter(last_name__icontains=request.POST['query']) | Contact.objects.filter(first_name__icontains=request.POST['query'])
