问题
I've got two models like below. The permission structure allows a Person to see any object that has a Group in common with them, so that if a Person is in Groups 1, 2, and 3, and an Object is shared with Groups 3, 4, 5, the Person can see it through Group 3.
class Person(models.Model):
groups = models.ManyToManyField(Group)
class Object(models.Model):
groups = models.ManyToManyField(Group)
The SearchIndex is like this:
class ObjectIndex(indexes.SearchIndex, indexes.Indexable):
groups = indexes.MultiValueField(null=True)
def prepare_groups(self, obj):
return [group.pk for group in obj.groups.all()] or None
So, what is the best way to create a SearchQuerySet
that allows me to take something like SearchQuerySet().models(Object).filter(groups=aperson.groups.all())
that is an OR on the groups instead of an AND?
回答1:
It looks like the correct way to do this is:
SearchQuerySet().models(Object).filter(groups__in=[g.id for g in aperson.groups.all()])
