在一頁中保存來自多個表單的數據

Question

我有一個頁面，有兩種形式。 用戶單擊編輯按鈕后，一個表單將顯示為彈出窗口。

我無法從單擊編輯按鈕后彈出的表單中保存信息。 不知道我做錯了什么。

這就是我的看法

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>

和編輯按鈕

                  <a href="#modal-update-credit-card" data-toggle="modal" class="btn btn-white btn-flat"><i class="fa fa-pencil fa-fw"></i> Edit</a>

這是我在網址中的內容

path('payment_view', teachers.payment_view, name='payment_view'),

更新

根據評論中的要求，這里是我刪除 commit=False 時的完整回溯

和表格

class TeacherSignUpForm(UserCreationForm):
    email = forms.EmailField(max_length=100)
    first_name = forms.CharField(max_length=100)
    last_name = forms.CharField(max_length=100)
    linkedin = forms.URLField(max_length=200)
    address = forms.CharField(max_length=500)
    billing_name = forms.CharField(max_length=200)
    account_num = forms.IntegerField()
    bank_name = forms.CharField(max_length=50)
    branch_code = forms.IntegerField()

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

    def save(self, commit=True):
        self.instance.is_teacher = True
        user = super(UserCreationForm, self).save(commit=False)
        user.email = self.cleaned_data['email']
        user.first_name = self.cleaned_data['first_name']
        user.last_name = self.cleaned_data['last_name']
        user.save()
        mentor = Mentor.objects.get_or_create(
            user=user,
            linkedin=self.cleaned_data['linkedin'],
            address=self.cleaned_data['address'],
            billing_name=self.cleaned_data['billing_name'],
            account_num=self.cleaned_data['account_num'],
            bank_name=self.cleaned_data['bank_name'],
            branch_code=self.cleaned_data['branch_code'],
        )
        return user
...
class MentorPaymentForm(forms.ModelForm):
    class Meta:
        model = Mentor
        fields = ('address', 'billing_name', 'account_num', 'bank_name', 'branch_code')

Answer 1

def save(self, commit=True):
        user = super(UserCreationForm, self).save(commit=False)
        user.is_teacher = True
        user.email = self.cleaned_data['email']
        user.first_name = self.cleaned_data['first_name']
        user.last_name = self.cleaned_data['last_name']

        mentor = Mentor.objects.get_or_create(
            user=user,
            linkedin=self.cleaned_data['linkedin'],
            address=self.cleaned_data['address'],
            billing_name=self.cleaned_data['billing_name'],
            account_num=self.cleaned_data['account_num'],
            bank_name=self.cleaned_data['bank_name'],
            branch_code=self.cleaned_data['branch_code'],
        )
        if commit:
            user.save()
        return user

user,mentor = form.save(commit=False)可以只是form.save()

Answer 2

我有一個包含 4 個表單的頁面，盡管從技術上講我將它用作 1 個唯一表單（基本 html），然后在“def post”中我處理 request.POST.dict()，根據外鍵，我把它放在它所屬的地方，但它是一個簡單的形式，不是模型形式或 django 形式。

另一方面，我建議您切換到CBV，它使您更輕松，FBV確實很乏味。
