Django創建CreateView所需的布爾字段

Question

我有一個模型，需要用戶在繼續之前選中復選框。 如果未選中該復選框，則瀏覽器不應允許用戶繼續提交表單（簡單，對吧？）

我正在使用CreateView來處理此模型，但它不起作用-可以在不勾選復選框的情況下提交表單（ patient_agreement BooleanField）。

如何使此CreateView CBV需要此復選框？

這是我的模型：

class Patient(models.Model):

    name = models.CharField(max_length=30, blank=False, verbose_name=_('Name'))
    surname = models.CharField(max_length=70, blank=False, verbose_name=_("Surname"))
    patient_agreement = models.BooleanField(
          blank=False,
          verbose_name=_("Patient has been notified about GDPR and his right to his data"),
          help_text=_("Mark only if you have informed the patient about his rights in the GDPR context"),

    )

這是我的觀點：

class NewPatientFormView(LoginRequiredMixin, CreateView):
    model = Patient
    fields = ['name', 'surname','patient_agreement']

    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.created_by_user = self.request.user
        # self.object.save()
        return super().form_valid(form)

如何在提交表單之前選中所需的復選框？

我的建議是為表單中的字段添加自定義驗證方法，該方法要求它等於True才能通過驗證。

## forms.py

class PatientForm(Form):

...

    def clean_patient_agreement(self):
        pa_value = self.cleaned_data.get('patient_agreement',False)

        ## Return value if True (checked)
        if pa_value:
            return pa_value

        ## Raise exception if not checked
        raise ValidationError('Must check patient agreement box to proceed')
