Django 中不同角色的权限

Question

I am creating an authentication system for my Django web-app. This is my model:

class Student(models.Model):
    name = models.CharField(max_length=300)

    def __str__(self):
        return self.name

class Teacher(models.Model):
    name = models.CharField(max_length=300)
    total_earnings = models.IntegerField(default="0")
    month_earnings = models.IntegerField(default="0")

    def __str__(self):
        return self.name

class Clase(models.Model):
    name = models.CharField(max_length=300)
    counter = models.IntegerField(default="6")
    language = models.CharField(max_length=10,choices=LANGUAGE_CHOICES, default='english')
    students = models.ManyToManyField(Student)
    teachers = models.ManyToManyField(Teacher)

    def __str__(self):
        return self.name

I want to give different permissions and features to teachers and students, but I have no clue on how. Any ideas? Thanks!

Answer 1

You can use the default authentication and permission mechanism of Django. You just need to extend User model.

   class Teacher(User):
        name = models.CharField(max_length=300)
        total_earnings = models.IntegerField(default="0")
        month_earnings = models.IntegerField(default="0")

   class Student(User):
       name = models.CharField(max_length=300)

You can then create a Student and Teacher object with appropriate permissions as the same as User . It will also create an User object. Then, you can access permission as you access on User instance.

     teacher.get_all_permissions() # returns permissions of a teacher
     student.get_all_permissions() # returns permissions of a student
