Question

我正在尝试标记出勤率。但我无法获得代码。我的提交应该将每个学生的输入发送到数据库。欢迎任何以更好方式执行此操作的建议。我的models.py如下它有Employee，Mentor和Student，下面是可以更改值的模型。

class ClassName(models.Model):
 class_name = models.CharField(max_length=20)
 class_date=models.DateField(blank=True, null=True)
 Mentor= models.ForeignKey(Mentor, related_name='class_mentor')
 student = models.ManyToManyField(Student, related_name='class_student')
 attendance = models.BooleanField(default=True)

 def __str__(self):
    return str(self.class_name)

Views.py ：这只是为了显示markattendance 页面。我无法弄清楚如何获取值并将值发布到数据库。现在，我正在从学生表中获取学生值。我想我应该创建类名表格并展示学生。我收到内部服务器错误。def markattendance(request): students = Student.objects.all() return render(request, 'home/markattendance.html', {'students': students})

markattendance.html ：点击提交时，应标记出勤率。

{% extends 'home/index.html' %}
