Question

以下是我在views.py中的代码。我有一个正在创建和预填充的FormView，但是当我提交它时，它不会转到form_valid（），当它转到form_invalid（）时，它不会打印出任何错误。

非常感谢任何帮助。

views.py

class CleanTeamMainContactView(LoginRequiredMixin, FormView):
    template_name = "cleanteams/main_contact.html"
    form_class = EditCleanTeamMainContact
    success_url = "mycleancity/index.html"

    def get_initial(self, clean_team_member):
        initial = {}

        if clean_team_member:
            clean_team = clean_team_member.clean_team
            contact_user = clean_team.contact_user

            initial['contact_first_name'] = contact_user.first_name
            initial['contact_last_name'] = contact_user.last_name
            initial['contact_email'] = contact_user.email
            initial['contact_phone'] = clean_team.contact_phone
            initial['clean_ambassadors'] = clean_team.contact_user.id
            initial['clean_team_id'] = clean_team.id

        return initial

    # Initialize the form with initial values
    def get_form(self, form_class): 
        clean_team_member = self.request.user.profile.clean_team_member

        return form_class(
            clean_team=clean_team_member.clean_team,
            initial=self.get_initial(clean_team_member)
        )

    def form_invalid(self, form, **kwargs):
        context = self.get_context_data(**kwargs)
        context['form'] = form

        print form.errors
        return self.render_to_response(context)

    def form_valid(self, form):
        clean_team_id = form.cleaned_data['clean_team_id']

        try:
            clean_team_member =     CleanTeamMember.objects.get(user=self.request.user)
            clean_team_member.clean_team.update_main_contact(form.cleaned_data)
        except Exception, e:
            print e

        return HttpResponseRedirect(u'/clean-team/%s' %(clean_team_id))

我认为没有为表单提供数据的原因是因为您覆盖了get_form方法而没有将request.POST数据传递给它。我认为替代覆盖get_form_kwargs方法更合适，而不是覆盖该方法。

class CleanTeamMainContactView(LoginRequiredMixin, FormView):
    template_name = "cleanteams/main_contact.html"
    form_class = EditCleanTeamMainContact
    success_url = "mycleancity/index.html"

    def get_initial(self, clean_team_member):
        ...

    def get_form_kwargs(self):
        clean_team_member = self.request.user.profile.clean_team_member
        kwargs = {
            "initial": self.get_initial(clean_team_member),
            "clean_team": clean_team_member.clean_team
        }
        if self.request.method in ("POST", "PUT"):
            kwargs.update({
                "data": self.request.POST,
                "files": self.request.FILES
            })
        return kwargs

    def form_invalid(self, form, **kwargs):
        ...

    def form_valid(self, form):
        ...

这应该有望解决空form.data问题，但我不确定该表单是否仍然无效。

Django表单不提交，也没有抛出任何错误
