我有这些型号:
def Foo(Models.model):
size = models.IntegerField()
# other fields
def is_active(self):
if check_condition:
return True
else:
return False
def Bar(Models.model):
foo = models.ForeignKey("Foo")
# other fields
现在,我想查询具有活动FOO的条形图:
Bar.objects.filter(foo.is_active())
我收到错误,如
SyntaxError at /
('non-keyword arg after keyword arg'
我怎样才能做到这一点呢?
