Question

假设我有这本词典

mydict['number'] = {23,24,25}
mydict['name'] = {"john","mike","kaff"}
mydict['area'] = {"london", "usa", "japan"}

我已经有了查询集qs

但我希望根据上面的dictionary内容进行额外的过滤，例如

qs.filter (where number __icontains in 23,24,25)

和qs.filter (where name __icontains in john, mike, kaff)依此类推

编辑：

这是我尝试但粗略的

query_list = []

for key1 in mydict.iteritems():
  for myval in  mydict[key1]:
    qry = qry + Q(myval__icontains= myval) |
query_list.append(qry)

queryset = Student.objects.filter(reduce(operator.and_, query_list))

Answer 1

我会将参数与filter个Q对象组合起来。 https://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects

Answer 2

您可以尝试这种方法：

for k, v in mydict:
    qs.filter('%s__icontains' % k=v)

如何根据Django中的字典及其键进行Q过滤搜索
