title: Django Query: How to find all posts from people you follow
body: <p>I'm currently building a website with the Django Framework. I want on the homepage of my website to display all posts made by people the user is following. Here are the classes for Profile, Story and Follow:</p>
  
  <pre><code>class Profile(AbstractBaseUser, PermissionsMixin):
     email = models.EmailField(unique=True)
     first_name = models.CharField(max_length=30, null=True)
     last_name = models.CharField(max_length=30, null=True)
  
  class Follow(models.Model):
     following = models.ForeignKey('Profile', on_delete=models.CASCADE, related_name="following")
     follower = models.ForeignKey('Profile', on_delete=models.CASCADE, related_name="follower")
     follow_time = models.DateTimeField(auto_now=True)
  
  class Story(models.Model):
     author = models.ForeignKey('accounts.Profile', on_delete=models.CASCADE, related_name="author")
     title = models.CharField(max_length=50)
     content = models.TextField(max_length=10000)
  </code></pre>
  
  <p>As you can see Follow uses two Foreign Keys to represent the following and the follower. Is there a way to query all stories from people the user is following?</p>
  
  <p>I really don't know what to filter. Or is this maybe a job for aggregation? If someone could help me, that would be awesome!</p>
  
  <pre><code>following_feed = Story.object.filter(???).order_by('-creation_date')
  </code></pre>
