Python 通过Django formset上载多个文件-多值DictKeyError

试图制作一个能够处理多个文件上传并将其存储到标准位置的应用程序，但我遇到了一个问题。提交表单时，django在/pdfchecker处返回“MultiValueDictKeyError”/

“'docfile'”

forms.py

    from django import forms

class UploadPdf(forms.Form):
    docfile = forms.FileField(label='Browse')

class UploadPdfUrl(forms.Form):
    docurl = forms.URLField(label='Address')

modelys.py

    from django.db import models

class handle_UploadPdf(models.Model):
    docfile = models.FileField(upload_to='.')

views.py

def上传（请求）：

HTML模板：

<div class="f_unify">
        <form class="simpleform" action="" method="post" enctype="multipart/form-data">
            {{ formsetFile.management_form }}
            {% for form in formsetFile.forms %}
                        <fieldset class="mainfieldset">
                        <legend class="outer">
                        <span class="legendtext">Check by URI</span>

                        </legend>

                        {% csrf_token %}
            {{ formURL.as_table }} 

                        <input type="submit" value="Check" />

            <table class='no_error'>        
            {% csrf_token %}
            {{ formsetFile.as_p }}

            </table>

                $('#add_more').click(function() {
                    if(i < maxRows) {
                    cloneMore('div.table:last', 'service' + i++);
                    }
                    else {
                        alert('You can only upload 10 files per instance')
                        }
                })

            </script>


        </form>

在views.py中

request.FILES['docfile']

引发多值DictKeyError，其中

if request.method == 'POST':
    formsetFile = UploadPdfFormSet(request.POST, request.FILES)

    if formsetFile.is_valid():
        newdoc = handle_UploadPdf(docfile = request.FILES['docfile'])
        newdoc.save()

        return HttpResponse('yey')

此代码段不检查请求的文件是否包含文件“docfile”，因此它给出了多值错误。因此，如果您在前面检查request.FILES中是否有“docfile”，那么它将解决错误

if formsetFile.is_valid() and 'docfile' in request.FILES:
    newdoc = handle_UploadPdf(docfile = request.FILES['docfile'])
    newdoc.save()

因为如果request.FILES['docfile']不在request.FILES中，它就不会编译still@rajasimon不。我修好了。不记得是怎么回事。哈哈。请在你的代码应答中添加一些描述，欢迎使用SO！虽然这段代码可以回答这个问题，但提供关于它如何和/或为什么解决问题的附加上下文将提高答案的长期价值。请仔细阅读，不便之处，敬请谅解。非常感谢您为我提供的资源。

if request.method == 'POST':
    formsetFile = UploadPdfFormSet(request.POST, request.FILES)

    if formsetFile.is_valid():
        newdoc = handle_UploadPdf(docfile = request.FILES['docfile'])
        newdoc.save()

        return HttpResponse('yey')

if formsetFile.is_valid() and 'docfile' in request.FILES:
    newdoc = handle_UploadPdf(docfile = request.FILES['docfile'])
    newdoc.save()
