我在调查表单中有9个隐藏的单选按钮，每个按钮都附有可见图像。这个想法是用户应该在移动到调查的下一页之前选择其中一个图像。然后，应用程序将存储提交图像的名称。
如果可能，我想强制forms.HiddenInput，以便用户 选择其中一个图片，然后才能进入下一页
我知道这听起来有点像一个愚蠢的问题，但有人知道这是否可行以及如何做到这一点？感谢
forms.py
class SurveyFormDV4(forms.ModelForm):
class Meta:
model = Person
fields = ['DV_positive']
widgets = {'DV_positive' : forms.HiddenInput}
models.py
class Person(models.Model):
....
....
DV_positive = models.CharField(null=True, max_length=100, blank=True)
def __unicode__(self):
return self
注意：如果我没有在此处传递blank=True，那么我是否会选择不选择的页面。

elif step == 22:
context.update({'first_image' : images[0],
'second_image' : images[1],
