如何在Django queryset中执行AND条件？

Question

I want to write a Django query equivalent to this SQL query:

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

In Django , i have a list for example :

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

How to construct the Djagno queryset filter?

Answer 1

Use the Q operator:

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

UPDATE

I have answered the question, but given your second, expanded question on how to obtain the combination

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%')

this should work:

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)
