如何在Course序列化程序中获取status_id？状态更新为>>

已删除状态-choices1-不需要它我的模特：

class Course(models.Model):
    name = models.CharField(max_length=255)

class Status(models.Model):

    COURSE_STATUS = (
        ('DONE', 'Done'),
        ('IN PROGRESS', 'In progress')
    )

    course_status = models.CharField(max_length=9, 
                                     choices=COURSE_STATUS,  
                                     default='DONE')
    course = models.ForeignKey(Course, 
                               on_delete=models.CASCADE,
                               related_name="courses")
    user = models.ForeignKey(settings.AUTH_USER_MODEL,
                             on_delete=models.CASCADE, 
                             related_name="students")

    class Meta:
        verbose_name_plural = 'Statuses'
        verbose_name = 'Status'
        unique_together = ('user', 'course')
我的序列化器：

class CourseSerializer(serializers.ModelSerializer):
    class Meta:
        model = Course
        fields = ['name']
