Question

我的Django表单应该创建并将几个不同的模型实例保存到数据库中。但是，当我检查管理员时，没有任何关于这种情况的提示。我一直在调整表格，但似乎没用。理想情况下，此表单将检查用户是否有足够的积分用于他想要的奖励，如果他有，则会创建必要的对象并扣除必要的积分。但是，虽然我进入了成功页面，但没有创建任何对象并将其保存到数据库中。

形式：

class Get_Reward(forms.Form):
    quantity = forms.IntegerField(label=_('Quantity'), error_messages={'invalid':'Must be a valid number'})
    reward_name = forms.CharField(max_length=50, widget=forms.HiddenInput(), label=_('Reward Name'), error_messages={'invalid':'Invalid reward'})
    def clean_quantity(self):
        return self.cleaned_data['quantity']
    def clean_reward_name(self):

        try:
            existing_reward = Reward.objects.get(reward_name=self.cleaned_data['reward_name'])
        except ObjectDoesNotExist:
            raise forms.ValidationError(_("The reward you requested does not exist."))
        return self.cleaned_data['reward_name']
    def save(self, request, *args, **kwargs):
        """
        Save all of the required data.
        """
        user = request.user
        user_points = Points.object.filter(affiliate__id=user.id).annotate(total_points=Sum('points'))
        user_points = user_points.total_points
        error_message = {'lookuperror':'You need to provide a valid quantity', 
                         'insufficient_points':"You don't have enough points for this purchase."}
        form = Get_Rewards(request.POST)
        try:
            quantity = form.cleaned_data['quantity']
            reward_name = form.cleaned_data['reward_name']
            rewards = Reward.objects.get(reward_name=reward_name)
        except LookupError:
            raise Http404
        try:
            points_cost = -(rewards.reward_cost * quantity)
        except ArithmeticError:
            raise Http404
        quote_price = -(points_cost)
        if user_points >= quote_price:
            reward_order = Points.objects.create(affiliate=user, reward=rewards, points=points_cost, from_reward=True, from_offer=False, from_referral=False)
            status_cost = Status_Code.objects.create(short_name="Pending", name="The order is currently being reviewed", description="The order is in queue")
            redeem_order = Redeem.objects.create(affiliate=user, reward=rewards, status_code=status_code)
            redeem_details = Redeem_Details.objects.create(redeem=redeem_order, quantity=quantity, quote_price=quote_price)
            """
            reward_order = Points(affiliate=user, reward=reward, points=points_cost, from_reward=True, from_offer=False, from_referral=False)
            reward_order.save()
            status_code = Status_Code(short_name="Pending", name="The order is currently being reviewed", description="The order is in queue")
            status_code.save()
            redeem_order = Redeem(affiliate=user, reward=rewards, status_code=status_code)
            redeem_order.save()
            redeem_details = Redeem_Details(redeem=redeem_order, quantity=quantity, quote_price=quote_price)
            redeem_details.save()
            """
            return HttpResponseRedirect(reverse('yum:reward_confirmation', args=(redeem_details.redeem_code,)))
        else:
            return render(request, 'yum_affiliates/reward.html', {'error_message':error_message['insufficient_points']})

查看：

class RedeemReward(SingleObjectMixin, FormView):
    template_name = 'yum_affiliates/reward.html'
    slug_field = 'reward_slug'
    form_class = Get_Reward
    model = Reward

    def post(self, request, *args, **kwargs):
        if not request.user.is_authenticated():
            return HttpResponseForbidden()
        self.object = self.get_object()
        return super(RedeemReward, self).post(request, *args, **kwargs)

    def get_success_url(self):
        return reverse('yum:reward_confirmation', args=(self.object.reward_slug, self.object.reward_code))

Django表格不保存
