I have a model which contains a user, each user is associated to a club, a club can contain many teams, pitches etc. I want to know how I should design my models so that I can display/edit information on teams/pitches based on the user logged in and the club associated to that user. My ClubInfo model contains a foreign key associated to the user, where as my other models (Team/Pitch) have foreign keys associated to the ClubInfo not the user. 

```
class ClubInfo(models.Model):

user = models.OneToOneField(User, on_delete=models.CASCADE)
club_name = models.CharField(max_length=50, default='')
club_logo = models.ImageField(upload_to='profile_pics', blank=True)
club_address1 = models.CharField(max_length=30)
club_address2 = models.CharField(max_length=30, default='')
club_address3 = models.CharField(max_length=30, default='')
club_town = models.CharField(max_length=30)
club_county = models.CharField(max_length=30)
club_country = models.CharField(max_length=30)

def __str__(self):
    return self.club_name

class Player(models.Model):

club_name = models.ForeignKey(ClubInfo, to_field='id', on_delete=models.CASCADE, unique=True)

class Pitch(models.Model):
club_name = models.ForeignKey(ClubInfo, to_field='id', on_delete=models.CASCADE, unique=True)

def __str__(self):
    return self.pitch_name
