使用formview django中的表单呈现附加信息

from django import forms

class AdditionalInfoForm(forms.Form):
    additional_info = forms.CharField(label='Additional Info', max_length=100)

from django.views.generic.edit import FormView

class AdditionalInfoView(FormView):
    template_name = 'additional_info.html'
    form_class = AdditionalInfoForm
    success_url = '/success/'

    def form_valid(self, form):
        # 处理表单提交成功的逻辑
        additional_info = form.cleaned_data['additional_info']
        # 进行附加信息的处理
        return super().form_valid(form)

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>

{% if additional_info %}
  <p>Additional Info: {{ additional_info }}</p>
{% endif %}

from django.urls import path
from .views import AdditionalInfoView

urlpatterns = [
    path('additional-info/', AdditionalInfoView.as_view(), name='additional_info'),
]
