class MyUserManager(BaseUserManager): 
    def create_user(self, name, skills, password=None): 

     if not name: 
      raise ValueError('Users must have a unique name ') 

     user = self.model(
      name=self.name, 
      skills=skills, 
     ) 
     user.set_password(password) 
     user.save(using=self._db) 
     return user 

    def create_superuser(self, name, skills, password): 
     """ 
     Creates and saves a superuser with the given email, date of 
     birth and password. 
     """ 
     user = self.create_user(
      name, 
      password=password, 
      skills=skills, 
     ) 
     user.is_admin = True 
     user.save(using=self._db) 
     return user 


class Freelancer(AbstractBaseUser, PermissionsMixin): 
    name = models.CharField(max_length=20, unique='true') 
    Password = models.CharField(max_length=20) 
    field_of_interest = models.CharField(max_length=200) 
    skills = models.TextField() 
    experience = models.TextField() 

    USERNAME_FIELD = 'name' 
    REQUIRED_FIELDS = ['skills'] 

    class Meta: 
     verbose_name = _('user') 
     verbose_name_plural = _('users') 

    def get_absolute_url(self): 
     return "https://stackoverflow.com/users/%s/" % urlquote(self.name) 

    def get_short_name(self): 
     return self.name 

    def get_full_name(self): 
     return self.name 

    def __str__(self): # __unicode__ on Python 2 
     return self.name 
    # 
    # def has_perm(self, perm, obj=None): 
    #  # "Does the user have a specific permission?" 
    #  # # Simplest possible answer: Yes, always 
    #  return True 

    def has_module_perms(self, applabel): 
     # "Does the user have permissions to view the app `app_label`?" 
     # Simplest possible answer: Yes, always 
     return True 

    # @property 
    # def is_staff(self): 
    #  # "Is the user a member of staff?" 
    #  # "Simplest possible answer: All admins are staf" 
    #  return self.is_admin 

，這就是我得到
