Question

class SomeBaseClass(models.Model):
    CHOICES_1 = (
     (1, '1'),
     (2, '2'),
     (3, '3'),
     (4, '4'),
     )
    ONETIME = 'OT'
    WEEKLY = 'WK'
    BIWEEKLY = 'BW'
    MONTHLY = 'MN'
    BIMONTHLY = 'BM'
    YEARLY = 'YR'
    CHOICES_2 = (
        (ONETIME, 'One Time'),
        (WEEKLY, 'Weekly'),
        (BIWEEKLY, 'Bi-Weekly'),
        (MONTHLY, 'Monthly'),
        (BIMONTHLY, 'Bi-Monthly'),
        (YEARLY, 'Yearly'),
    )
    CHOICES_3 = (
         (0,'0'),
         (1,'1'),
         (2,'2'),
         (3,'3'),
         (4,'4'),
         (5,'5'),
         (10,'10'),
    )
    field1 = models.CharField(max_length=10)
    field2 = models.DateTimeField(auto_now_add=True) 
    field3 = models.DateField()
    field4 = models.TimeField()
    field5 = models.SmallIntegerField(choices=CHOICES_1)
    field6 = models.CharField(max_length=2,choices=CHOICES_2)
    field7 = models.SmallIntegerField(choices=CHOICES_3)
    field8 = models.CharField(max_length=80)
    field9 = models.TextField(max_length=300)
    class Meta:
        abstract = True

class SomeDerivedClass(SomeBaseClass):
    field10 = models.DateTimeField()
    field11 = models.ForeignKey(Business, blank=True)


class SomeDerivedClassForm(forms.ModelForm):
    class Meta:
        model = SomeDerivedClass
        exclude = ['field2']
        exclude = ['field10']
        exclude = ['field11']

当＆＃34; SomeDerivedClassForm＆＃34;即使我已将其设置为排除，现场10也会显示在网站上。在此之前，我在基类中有field11，那时field10没有以渲染的形式显示，但是field11即使被排除在外也显示出来。我意识到我的代码中必定有一些错误，但是我没看到它是什么您是否需要做一些特殊的事情来使用派生类的表单？

Answer 1

我不确定这是那么简单。

在您的代码中，不是在此处，每次要向其添加字段时，都会覆盖exclude列表。

 exclude = ['field2']
 exclude = ['field10']
 exclude = ['field11']

写：

 exclude = ['field2', 'field10', 'field11']

Django，抽象模型类+派生模型＆amp;表格“排除”字段问题
