Python 在一个页面中保存多个表单中的数据

我有一个页面有两种形式。一个表单在用户单击编辑按钮后显示为弹出窗口

我无法保存单击“编辑”按钮后弹出的表单中的信息。不知道我做错了什么

这就是我的看法

def payment_view(request):
    form = MentorPaymentForm()
    if request.method == 'POST':
        form = MentorPaymentForm(request.POST, request.FILES, instance=request.user)
        if form.is_valid():
            user,mentor = form.save(commit=False)
            return redirect('teachers:payment_view')
    else:
        form = MentorPaymentForm(instance=request.user)
    return render(request, 'classroom/teachers/app-instructor-billing.html', {'form': form})

我的模板：

<form id="billing_details", method="post">
                        {% csrf_token %}
                          <label class="col-md-2 control-label">Account Number</label>
                          <div class="form-group form-control-material">
                            {{ form.account_num }}
                          </div>
                          <label for="bankname" class="col-md-2 control-label">Bank Name</label>
                          <div class="form-group form-control-material" id="bankname">
                            {{ form.bank_name }}
                          </div>
                          <label for="acc_num" class="col-md-2 control-label">Branch Code</label>
                          <div class="form-group form-control-material">
                            {{ form.branch_code }}
                          </div>
                          <button type="submit" class="btn btn-success paper-shadow relative" data-z="0.5" data-hover-z="1" data-animated data-dismiss="modal">Update Payment Details</button>
                        </form>

更新

正如在这里的评论中所要求的，当我删除commit=False时，将进行完整的回溯

    class Meta(UserCreationForm.Meta):
        model = User
        fields = ('email', 'username', 'first_name', 'last_name')

    def save(self, commit=True):

user，mentor=form.save（commit=False）

可以是

form.save（）

我有一个包含4个表单的页面，虽然从技术上讲，我将其用作一个唯一表单（基本html），然后在“def post”中处理请求。post.dict（），我根据外键设置了手动验证，并将其保存在它所属的位置，但它是一个简单的表单，不是modelform或django表单

另一方面，我建议您切换到CBV，这会使您的工作更轻松，实际上FBV很乏味。

表单是否相互关联？为什么不使用javascript单独发送请求呢？它们是相关的。什么意思？

user，mentor=form.save（commit=False）

commit=False将获取一个模型对象，但它不会将其保存到db，您需要调用user.save（）或mentor.save（）。。无论您在这里遇到什么情况，都需要这样做。您可以使用ajax提交第二个表单，类似于此链接[并使用drf在服务器端保存对象。如果需要某种外键，您可以首先保存第一个表单，并在表单的隐藏字段中使用js设置fk。@MahsaMonavari getting page在链接上不存在
