django TemplateView 和表单

Question

我有一些问题要弄清楚新的 django View (模板 View )和表单如何工作我也找不到好的资源，官方文档没有解释我如何获取请求(我的意思是获取和发布)和新表单django View 类

谢谢

添加以便更好地解释

例如我有这个表格:

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    message = forms.CharField()
    sender = forms.EmailField()
    cc_myself = forms.BooleanField(required=False)

这是读取和打印表单的代码(老式方式):

def contact(request):
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...
            return HttpResponseRedirect('/thanks/') # Redirect after POST
    else:
        form = ContactForm() # An unbound form

    return render_to_response('contact.html', {
        'form': form,
    })

好吧，我的问题是如何用模板 View 做同样的事情谢谢

改用 FormView，即

from django.views.generic import TemplateView, FormView

from forms import ContactUsEmailForm


class ContactView(FormView):
    template_name = 'contact_us/contact_us.html'
    form_class = ContactUsEmailForm
    success_url = '.'

    def get_context_data(self, **kwargs):
        context = super(ContactView, self).get_context_data(**kwargs)
        #context["testing_out"] = "this is a new context var"
        return context

    def form_valid(self, form):
        # This method is called when valid form data has been POSTed.
        # It should return an HttpResponse.
        #form.send_email()
        #print "form is valid"
        return super(ContactView, self).form_valid(form)

更多关于 FormView in Django Docs

从技术上讲，也可以使用 TemplateView，只需覆盖 post 方法，因为默认情况下模板 View 不允许您发布到它:

class ContactUsView(TemplateView):
    template_name = 'contact_us/contact_us.html'

    def post(self, request, *args, **kwargs):
        context = self.get_context_data()
        if context["form"].is_valid():
            print 'yes done'
            #save your model
            #redirect

        return super(TemplateView, self).render_to_response(context)

    def get_context_data(self, **kwargs):
        context = super(ContactUsView, self).get_context_data(**kwargs)

        form = ContactUsEmailForm(self.request.POST or None)  # instance= None

        context["form"] = form
        #context["latest_article"] = latest_article

        return context

我认为 FormView 更有意义。
