Python 我想将表单的复选框值保存到Django数据库中

我在Django Web应用程序中使用表单，表单由复选框组成，但当复选框标记为true且表单已提交时，数据库中不会标记复选框更改

这是my models.py我的帮助模型没有将复选框值发送到数据库

# Create your models here.

class Contact(models.Model):
    name = models.CharField(max_length=122)
    email = models.CharField(max_length=122)
    phone = models.CharField(max_length=12)
    desc = models.TextField()
    date = models.DateField()
    def __str__(self):
        return self.name


class Help(models.Model):
    name = models.CharField(max_length=122)
    address = models.TextField()
    phone = models.CharField(max_length=12)
    bed = models.BooleanField("bed",default=False)
    oxygen = models.BooleanField("oxygen",default=False)
    plasma = models.BooleanField("plasma",default=False)
    date = models.DateField()

    def __str__(self):
        return self.name

这是我的观点
