Django ManyToManyField Retrieving both objects error - django

Question

I implemented a ManyToManyField for a following feature which allows users to follow other users and if they follow other user .
They would able to retrieve their's objects.
This is my module
class Person(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=100, blank=True)
image = models.FileField(upload_to="images/",blank=True)
following = models.ManyToManyField('self', related_name='followers', symmetrical=False, blank=True, null=True)
birthday = models.DateField(blank=True,null=True)
def __unicode__(self):
return self.name
class Board(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=100)
created = models.DateTimeField(auto_now_add=True)
picture = models.OneToOneField('Picture',related_name='picture',blank=True,null=True)
def __unicode__(self):
return self.name
The problem is when a user is following 2 users . I am only able to retrieve a single user objects instead of both users.
For example I created 3 users , Jimmy , Sarah and Simon . Sarah is following Simon and Jimmy
Jimmy has a board called Jimmy's Math Board ,Jimmy English Board
Simon has a single board called Simon's Whiteboard
The problem is underneath
>>> from pet.models import *
>>> from django.contrib.auth.models import User
>>> user = User.objects.get(username='Sarah')
>>> person = Person.objects.get(user=user)
>>> sarah = Person.objects.get(user=user)
>>> sarah.following.all() # SARAH IS FOLLOWING JIMMY AND SIMON
[<Person: Jimmy>, <Person: Simon>]
>>> users = User.objects.filter(pk__in=sarah.following.all().values_list('user__pk',flat=True))
>>> users
[<User: Jimmy>, <User: Simon>] # I'm able to retrieve their users
>>> board = Board.objects.filter(user=users) # when I search for their boards , I only retrieve a single user . Jimmy's board not Simon
>>> board
[<Board: Jimmy's Math Board>, <Board: Jimmy English Board>]
>>> person = Person.objects.filter(user=users)
>>> person
[<Person: Jimmy>]
How Can I retrieve both of these users board?

Answer 1

Because board = Board.objects.filter(user=users) is filtering by user it expects one user to be provided. If you were to do something like board = Board.objects.filter(user__in=users) which uses the __in filter, the filtering will correctly use the list of user objects.
You could also use a flat list of id's instead of objects like so board = Board.objects.filter(user__in=sarah.following.all().values_list('user__pk',flat=T‌​rue))
