Question

我想保存SelfTaught（＆＃39;自学＆＃39;作为附图）的值，但是它提醒选择列表中的项目，我有模型和表单的部分代码如下：

class Course(models.Model):
    teacher = models.ForeignKey(
        User,
        on_delete=models.CASCADE, null=True,
        related_name="+"
    )

teacher = forms.ModelChoiceField(queryset=User.objects.filter(is_teacher=True),
                                empty_label='SeltTaught',label='Teacher' )

Answer 1

尝试添加required=False，如下所示，默认为True


teacher = forms.ModelChoiceField(queryset=User.objects.filter(is_teacher=True),
                                empty_label='SeltTaught',label='Teacher',required=True)

如何使用empty_lable保存ForeignKey的ModelChoiceField？ - Django
