python - 如何在django中制作表格的外观？

Question

我正在尝试制作一个表格，但它没有显示给我。相反，它给我错误 UnboundLocalError at/withdraw/local variable 'form' referenced before assignment 如何解决这个问题？

views.py

@login_required
def withdraw(request):
    if request.method == 'POST':
        form = Withdrawapayment(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, f'Your request has been submitted.')
            return redirect('balance')

    context = {'form': form}
    return render(request, 'nextone/withdraw.html', context)

模型.py

class WithdrawPayment(models.Model):
    payment = models.DecimalField(max_digits=100, decimal_places=2)

    class Meta:
        verbose_name_plural = 'Withdraw Payment'

表单.py

class Withdrawpayment(forms.ModelForm):
    class Meta:
        model = WithdrawPayment
        fields = ['payment']

您正在处理 POST 请求，因此请像这样更改您的 View :

@login_required
def withdraw(request):
    if request.method == 'POST':
        form = Withdrawapayment(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, f'Your request has been submitted.')
            return redirect('balance')
    else:
        form = Withdrawpayemnt()
    context = {'form': form}
    return render(request, 'nextone/withdraw.html', context)
