Question

我想创建一个凭证系统，并允许管理员创建多个具有不同值的凭证代码。

def randomString(stringLenght=8):
letters = string.ascii_letters + string.digits
return ''.join(random.sample(letters, stringLenght))


class VoucherCreateView(CreateView):
model = Voucher
form_class = VoucherCreateForm
template_name = 'voucher/VoucherCreateView.html'
success_url = reverse_lazy('voucher:voucher_create')

def form_valid(self, form):
    x = self.request.POST.get('value_x')
    x = int(x)
    for i in range(0, x):
        i = randomString()
        e = Voucher(voucher=i, money=self.request.POST['value_money'])
        e.save()
    return super(VoucherCreateView, self).form_valid(form)

Models.py：

class Voucher(models.Model):
voucher = models.CharField(max_length=8, unique=True)
money = models.SmallIntegerField(blank=True)
created = models.DateTimeField(auto_now_add=True)
used = models.BooleanField(default=False)

Forms.py：

class VoucherCreateForm(forms.ModelForm):
value_x = forms.IntegerField(required=True)
value_money = forms.IntegerField(required=True)

class Meta:
    model = Voucher
    fields = ['voucher', 'money']

我想使用请求将此添加到我的sql中。关于如何执行此操作的任何想法？

编辑// 解决方案如下，如果是这样的错误，则需要更改return super(VoucherCreateView, self).form_valid(form)，例如return HttpResponse('success')

您可以尝试使用django-bluk-create link

针对您的情况

def form_valid(self, form):
    x = self.request.POST.get('value_x')
    x = int(x)
    objs = [
        Voucher(voucher=randomString(), money=int('0' + self.request.POST['value_money']))
        for i in range(0, x)
    ]
    Voucher.objects.bulk_create(objs)
    return super(VoucherCreateView, self).form_valid(form)

如何向数据库发出多个请求？
