Comment

#'Company' is a related name as a parameter, it allows to squizz the _set
class User(models.Model):
    username = models.CharField(max_length=100, unique=True)
    companies = models.ManyToManyField('Company', blank=True)

class Company(models.Model):
    name = models.CharField(max_length=255)
    
#So, to get all the companies associated with a User, we can do :
User.companies.all()

#But the reverse is a bit tricky. 
#That is, how to get all users associated with a company.
#Very easy. Get the reverse relationship using _set
company.user_set.all()
#will return a QuerySet of User objects that belong to a particular company. 
#By default you use modelname_set to reverse the relationship, 
#but you can override this be providing a related_name 
#as a parameter when defining the model, i.e.
