python - 如何在提款时登录的管理页面添加用户名？

Question

我制作了一个表单来为用户提款提供一个选项。该数据保存在管理页面中，但问题是我也有 owner 变量，我希望它作为将要保存在管理页面中的 owner 用户名的数据量也应该保存在管理中，它显示了谁想要这个金额？

模型.py

from django.contrib.auth.models import User
class WithdrawPayment(models.Model):
    payment = models.CharField(max_length=100)
    owner = models.ForeignKey(User, on_delete=models.CASCADE)

    class Meta:
        verbose_name_plural = 'Withdraw Payment'

views.py

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

表单.py

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

像这样:

@login_required
def withdraw(request):
    form_class = WithdrawBalanceForm
    if request.method == 'POST':
        form = form_class(request.POST)
            obj = form.save(commit=False)
            obj.owner = request.user
            obj.save()
            messages.success(request, f'Your request has been submitted.')
            return redirect('index')
    else:
        form = form_class()
    context = {'form': form}
    return render(request, 'nextone/withdraw.html', context)

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