Question

我正在尝试在django应用程序中创建配置文件更新，我在浏览器中收到以下错误

local variable 'form' referenced before assignment

任何帮助将不胜感激。我现在很困惑。以下是我的views.py。感谢

View.py

def update_profile(request):
    if request.method == 'POST':
        form = UpdateProfile(request.POST or None, instance=request.user)
        profile_form = ProfileEditForm(data = request.POST or None,instance=request.user,files=request.FILES)

        if form.is_valid() and profile_form.is_valid():
            form.save()
            profile_form.save()
            return redirect('profiles')
    else:
        form = UpdateProfile(instance=request.user)
        profile_form = ProfileEditForm(instance=request.user)
    context = {
        "form": form,
        "profile_form": profile_form,
    }
    template = 'edit.html'
    return render(request, template, context)

form.py

class UpdateProfile(forms.ModelForm):
    username = forms.CharField(required=True)
    email = forms.EmailField(required=True)
    first_name = forms.CharField(required=False)
    last_name = forms.CharField(required=False)

    class Meta:
        model = User
        fields = ['first_name', 'last_name', 'username', 'email']

class ProfileEditForm(forms.ModelForm):

    class Meta:
        model = Profile
        fields = ('date_of_birth', 'photo')

将根据要求提供其他代码。

试试这个：

def update_profile(request):
    form = UpdateProfile()
    if request.method == 'POST':
        form = UpdateProfile(data = request.POST or None, instance=request.user)
        profile_form = ProfileEditForm(data = request.POST or None,instance=request.user,files=request.FILES)

        if form.is_valid() and profile_form.is_valid():
            form.save()
            profile_form.save()
            return redirect('profiles')
    else:
        form = UpdateProfile(instance=request.user)
        profile_form = ProfileEditForm(instance=request.user)
    context = {
        "form": form,
        "profile_form": profile_form,
    }
    template = 'edit.html'
    return render(request, template, context)
