Different results when order is changed.

[instasck]

I get wired behaver:

While changing the order of AND conditions:

I get this user appear.
While user have both many_to_many "he" and "ar"

This is the code I changed:

class FollowerLangField(StrField):
    name = 'language'
    model = Follower

    # def get_lookup_name(self):
    #     print(f'language__id')
    #     return 'language__id'

    # def get_lookup_value(self, value):
    #     lang_id = Language.objects.filter(code_name=value).first().id
    #     print(f'lang_id {lang_id}')
    #     return lang_id

    def get_lookup(self, path, operator, value):
        _search = 'language__id' #'__'.join(path + [self.get_lookup_name()])
        _op, invert = self.get_operator(operator)
        _value = Language.objects.filter(code_name=value).first().id
        print('debug get_lookup:',_search, _op, invert, _value)
        if operator == '!=':
            q = models.Q(**{'%s%s' % (_search, _op): _value})
        else:
            q = models.Q(**{'%s%s' % (_search, _op): _value})
        return ~q if invert else q


...
model:
class Follower(models.Model):
    language = models.ManyToManyField(
            "instagram_data.Language", verbose_name=_("language_code_name"), blank=True)


class Language(models.Model):
    code_name = models.CharField(max_length=6, null=True, blank=True)

    def __str__(self):
        return self.code_name

It seems to ignore the second "language" condition.

Y?
