通过TemplateView保存表单

# views.py
from django.views.generic import TemplateView
from myapp.forms import MyForm
from myapp.models import MyModel

class MyView(TemplateView):
    template_name = 'my_template.html'
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['form'] = MyForm()  # 在上下文中传递表单对象给模板
        return context
    
    def post(self, request, *args, **kwargs):
        form = MyForm(request.POST)
        if form.is_valid():
            # 表单验证通过，保存数据到数据库
            data = form.cleaned_data
            MyModel.objects.create(**data)
            return self.form_valid(form)
        else:
            # 表单验证失败，重新渲染模板，并将错误信息传递给模板
            return self.form_invalid(form)

<!-- my_template.html -->
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">提交</button>
</form>
{% if messages %}
  {% for message in messages %}
    <p>{{ message }}</p>
  {% endfor %}
{% endif %}
