    """Project Model. 
    """ 
    name = models.CharField(unique=True, max_length=255) 
    manager = models.ForeignKey('Employee', blank=True, null=True) 
    project = models.Manager() 



class Employee(models.Model): 
    """ 
    Employee Model. 
    """ 
    first_name = models.CharField(max_length=255) 
    last_name = models.CharField(max_length=255) 
    email = models.CharField(
     unique=True, 
     max_length=255, 
     blank=True, 
     null=True) 
    projects = models.ManyToManyField('Project', blank=True) 
    employee = models.Manager()

私はこの問題を自分で持っていました。私はDjango 1.10から1.10.2にアップグレードしました。それは私のために修正されたようです。がんばろう。
