Django 表单未显示正确的字段

Question

让用户更改信息字段的 django 表单应该让他们更改用户名、电子邮件、姓名和 last_name，但它会显示他们的国籍、性别、应用程序分数和生日。

views.py

def  profileedit_view(request):
    if request.method== 'POST':
        form= PerfilEditadoForm(request.POST, instance = request.user)
        if form.is_valid():
            form.save()
            return redirect('login')
        else:
            form= PerfilEditadoForm(instance=request.user)
            args= {'form': form}
            return render(request, 'profileedit', args)

    form = UsuarioForm(request.POST or None)
    if form.is_valid():
        form.save()

    context = {
        'form': form
    }
    return render(request, "profileedit.html", context)

forms.py

class PerfilEditadoForm(UserChangeForm):
    class Meta:
        model = User
        fields= ('email', 'username', 'first_name', 'last_name')

profileedit.py

<form method="POST" action="#"> {% csrf_token %}
        <p>
        {{ form.as_ul }}
        <button class="btn btn-primary py-1 px-2" type="submit" > Save </button>
        </p>
        </form>

Answer 1

在forms.py 更改括号 - 使用 [] 而不是 ()

class PerfilEditadoForm(UserChangeForm):
    class Meta:
        model = User
        fields= ['email', 'username', 'first_name', 'last_name']

Answer 2

您的表单正在被 form = UsuarioForm(request.POST or None) 覆盖。假设您要显示的字段属于 PerfilEditadoForm，您应该将该行更改为 form = PerfilEditadoForm(request.POST or None).

我的建议是将该特定行移动到 if request.method== 'POST': 之前。像

def  profileedit_view(request):
    form= PerfilEditadoForm(request.POST or None)
    if request.method== 'POST':
        form.instance = request.user
        if form.is_valid():
            form.save()
            return redirect('login')
        else:
            form= PerfilEditadoForm(instance=request.user)
            args= {'form': form}
            return render(request, 'profileedit', args)

    context = {
        'form': form
    }
    return render(request, "profileedit.html", context)
