Question

我正在尝试在Django中上传多个文件，并通过DropzoneJS将它们存储在系统中。我在request.FILES中的MultiValueDict字典中获取文件。但是，它看起来像：

<MultiValueDict: {u'file[1]': [<TemporaryUploadedFile: DSC07077.jpg (image/jpeg)>], u'file[0]': [<TemporaryUploadedFile: DSC06856.JPG (image/jpeg)>]}>

上传的文件不在同一个密钥中，因此我无法使用request.FILES.getlist（＆＃39; file＆＃39;），我不知道该怎么办。

我的观点功能是：

def upload_files(request):
    if request.method == 'POST':
    form = UploadFileForm(request.POST, request.FILES)
    print request.FILES
    if request.FILES:
        for f in request.FILES.getlist('file'):
            handle_uploaded_file(f)
        return HttpResponseRedirect('/swupdate/index/')


def handle_uploaded_file(f):
with open( settings.MEDIA_ROOT + f.name, 'wa') as destination:
    for chunk in f.chunks():
        destination.write(chunk)

我的表格：

class UploadFileForm(forms.Form):
file  = forms.FileField()

我的模板表单：

<form id="my-awesome-dropzone" class="dropzone" action='/index/upload_files/' method="post" enctype="multipart/form-data">
{% csrf_token %}
<!-- Now setup your input fields -->
<input type="email" name="username" />
<input type="password" name="password" />                                         
<div class="dropzone-previews"></div> <!-- this is were the previews should be shown. -->
<button id='SubmitAll' type="submit">Submit data and files!</button>
</form>

<script src="{% static 'js/dropzone.js' %}"></script>
<script type="text/javascript">
    Dropzone.options.myAwesomeDropzone = { // The camelized version of the ID of the form element

    // The configuration we've talked about above
    autoProcessQueue: false,
    uploadMultiple: true,
    parallelUploads: 100,
    maxFiles: 100,
    addRemoveLinks: true,


    // The setting up of the dropzone
    init: function() {
    var myDropzone = this;
    // First change the button to actually tell Dropzone to process the queue.
    this.element.querySelector("button[type=submit]").addEventListener("click",      function(e) {
    // Make sure that the form isn't actually being sent.
        e.preventDefault();
        e.stopPropagation();
        myDropzone.processQueue();
    });

    // Listen to the sendingmultiple event. In this case, it's the sendingmultiple event instead
    // of the sending event because uploadMultiple is set to true.
    this.on("sendingmultiple", function() {
    // Gets triggered when the form is actually being sent.
    // Hide the success button or the complete form.
    });
    this.on("successmultiple", function(files, response) {
    // Gets triggered when the files have successfully been sent.
    // Redirect user or notify of success.
    });
    this.on("errormultiple", function(files, response) {
    // Gets triggered when there was an error sending the files.
    // Maybe show form again, and notify user of error
    });
    }
    }
    </script>

非常感谢

我不确定为什么文件会以不同的键添加到dict中，但您可以执行以下操作：

for key in request.FILES:  # So each iteration, key will have the key of the dict

在您的代码中，您应该尝试：

# Your code ......
for key in request.FILES:
    handle_uploaded_file(request.FILES[key])
return HttpResponseRedirect('/swupdate/index/')
# ... Your code ...
