Question

我在/ accounts / upload_save /出现错误，AttributeError 'WSGIRequest'对象没有属性'cleaning_data'。我正在制作文件上传系统。如果我选择文件并放入“发送”按钮，所选图像将被发送到模型。但是现在，当我选择图像并放入“发送”时“按钮，错误发生了。我在views.py中写道

@login_required
@csrf_exempt
def upload_save(request):
    form = UserImageForm(request.POST, request.FILES)
    if request.method == "POST" and form.is_valid():
            data = form.save(commit=False)
            data.user = request.user
            data.image = request.cleaned_data['image']
            data.save()
            return render(request, 'photo.html')

    else:
        form = UserImageForm()
        return render(request, 'profile.html', {'form': form})

index.html中的

<main>
    <div class="detailimg col-xs-8">
        <div class="relative_ele">

            <div class="container" id="photoform">
                {% if form.errors %}　
                <div class="alert alert-danger" role="alert">
                    　<p>At least 1 picture should be selected</p>　　
                </div>
                {% endif %}

                <form action="/accounts/upload_save/" method="POST" enctype="multipart/form-data">
                    {% csrf_token %}
                    <div class="input-group">
                        <label class="input-group-btn" style="width: 80px;">
                            <span class="file_select btn-lg">
                                File Select1
                                <input type="file" name="image">
                            </span>
                        </label>
                        <input type="text" class="form-control" readonly="">　　
                    </div>
                    <div class="input-group">
                        <label class="input-group-btn" style="width: 80px;">
                            <span class="btn-lg file_select">
                            File Select2
                            <input type="file" name="image2">
                            </span>
                        </label>
                        <input type="text" class="form-control" readonly="">　　
                    </div>
                    <div class="form-group">
                        <input type="hidden" value="{{ p_id }}" name="p_id" class="form-control">
                    </div>
                    <div class="col-xs-offset-2">
                        <div class="form-group">
                            <input type="submit" value="SEND" class="form-control">
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</main>

我真的不明白为什么会发生这种错误。我在views.py中重写了

@login_required
@csrf_exempt
def upload_save(request):
    if request.method == "POST":
        form = UserImageForm(request.POST, request.FILES)
        if form.is_valid():
            data = form.save(commit=False)
            data.user = request.user
            data.image = form.cleaned_data['image']
            data.save()
        else:
            print(form.errors)
    else:
        form = UserImageForm()

    return render(request, 'registration/photo.html', {'form': form})

但同样的错误发生。我该如何解决这个问题？我的代码中的WSGIRequest是哪一点？

Answer 1

request.cleaned_data['image']无效，您应该在第二个示例中使用form.cleaned_data。

如果你得到相同的AttributeError，那么你还没有重新启动服务器并仍在运行旧代码。

您可能根本不需要data.image = form.cleaned_data['image']行。模型表单将负责设置图像字段。使用commit=False保存后，您只需要更改表单中未包含的字段。

if request.method == "POST" and form.is_valid():
        data = form.save(commit=False)
        data.user = request.user
        data.save()

/ accounts / upload_save /'WSGIRequest'对象的AttributeError没有属性'cleaning_data'
