使用用户 manyTomany 过滤对象 manyTomany

Question

I want to filter the model Foo by its manyTomany field bar with users bar .

Models

class User(models.Model):
  bar = models.ManyToManyField("Bar", verbose_name=_("Bar"), blank=True)

class Foo(models.Model):
  bar = models.ManyToManyField("Bar", verbose_name=_("Bar"), blank=True)

class Bar(models.Model):
  fubar = models.CharField()

with this

user = User.objects.get(id=user_id)

I want to gett all Foo's that have the same Bar's that the User has. I would like this to work:

bar = Foo.objects.filter(foo=user.foo)

but it doesn't work.

Answer 1

foos = Foo.objects.filter(bar__in=user.bar.all())
