如何在Django queryset中執行AND條件？

Question

我想編寫一個與此SQL查詢等效的Django查詢：

SELECT * FROM user WHERE name LIKE '%danny%' AND name LIKE '%jack%' AND name LIKE '%peter%' ...

在Django ，我有一個列表，例如：

lst=['danny','jack','peter']

如何構造Djagno queryset過濾器？

Answer 1

使用Q運算符：

queryargs = [Q(name__contains=i) for i in lst]
queryset = User.objects.filter(*queryargs)

我已經回答了這個問題，但是考慮到您的第二個擴展問題，即如何獲得組合

SELECT * FROM user WHERE (name LIKE '%danny%' AND name LIKE '%jack%' AND name LIKE '%peter%') OR (family LIKE '%danny%' AND family LIKE '%jack%' AND family LIKE '%peter%')

這應該工作：

from django.db.models import Q

qname = Q()
for i in lst:
    qname &= Q(name__contains=i)

qfamily = Q()
for i in lst:
    qfamily &= Q(family__contains=i)

queryset = Data.objects.filter(qname | qfamily)
