Django FormView不保存 [英] Django FormView Not Saving

问题描述

我的表单没有保存我需要的模型.我的表格:

My form isn't saving the models that I need it to. My form:

class RewardForm(forms.Form):
    quantity = forms.IntegerField(max_value=10, min_value=1, label=_('quantity'), initial=1)
    reward = forms.CharField(max_length=50, label=_('reward'))
    reward_denomination = forms.ModelChoiceField(queryset=Reward_Denomination.objects.all(), widget=forms.RadioSelect)

    def clean_reward(self):
        data = self.cleaned_data.get('reward')
        try:
            reward = Reward.objects.get(reward_name=data)
        except ObjectDoesNotExist:
            raise forms.ValidationError(_('Reward does not exist'), code='invalid')
        return data

    def clean_reward_denomination(self):
        data = self.cleaned_data.get('reward_denomination')
        try:
            denomination = Reward_Denomination.objects.get(denomination=data)
        except ObjectDoesNotExist:
            raise forms.ValidationError(_('Denomination does not exist'), code='invalid')
        return data

    def save(self, request, commit=True):
        user = request.user
        data = self.cleaned_data

        'try:
            post_reward = data['reward']
            post_denomination = data['reward_denomination']
            quantity = data['quantity']
        except LookupError:
            raise Http404

        reward = Reward.objects.get(reward_name=post_reward)
        denomination = Reward_Denomination.objects.get(denomination=post_denomination)
        user_points = Points.objects.filter(affiliate__id=user.id).aggregate(total_points=Sum('points'))
        user_points = user_points['total_points']

        try:
            total_cost = (quantity * denomination.cost)
        except ArithmeticError:
            raise Http404

        quote_price = -total_cost

        if user_points >= total_cost:
                reward_order = Points.objects.create(affiliate=user, points=quote_price, from_reward=True, from_offer=False)
                status_coded = 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, status_code=status_coded, quantity=quantity, reward=reward, price=total_cost)

        return reward_order

我的观点:

class Reward_Detail(DetailView):
    model = Reward
    slug_field = 'reward_slug'
    context_object_name = 'reward'
    template_name = 'omninectar/reward.html'


#Detail Stuff

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

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        return super(RedeemReward, self).post(request, *args, **kwargs)

    def get_success_url(self):
        return reverse('omni:reward_confirmation')

class RewardBeautify(View):
    def get(self, request, *args, **kwargs):
        view = Reward_Detail.as_view()
        return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        view = RedeemReward.as_view()
        return view(request, *args, **kwargs)

因此，我最初认为FormView将处理表单处理(验证，如果有效，则运行form.save()等).我正在追踪 FormView ，Django网站上的SingleObjectMixin 示例.尝试提交表单时，我没有收到任何错误，但是也没有创建任何对象.我试过定义一个运行save方法的form_valid方法，试过将它放在formview的post方法中，等等.有人可以发现错误吗?谢谢！

So I initially thought that the FormView would handle the form processing (validate, and, if valid, run form.save(), etc). I'm following the FormView, SingleObjectMixin example on the Django website. I don't receive any errors when I try and submit the form, but no objects are created either. I've tried defining a form_valid method that runs the save method, I've tried putting it inside the post method in the formview, etc. Can anyone spot the error/errors? Thanks!

推荐答案

我也是查看类的新手，而Django 1.6也存在几乎相同的问题.

I'm new to view classes too and I had almost the same problem with Django 1.6.

您应该添加

def form_valid(self, form):
    form.save()
    return super(RedeemReward, self).form_valid(form)

将

方法覆盖到您的RedeemReward类.这对我有用.

method overriding to your RedeemReward class. This worked for me.

如果查看Django源代码，您会发现FormView类继承链中没有保存表单.

If you look to Django source code, you will see that there is no form saving in FormView class inheritance chain.
