Question

我有一个上传表单，允许用户上传照片，word文档或两者。我需要逻辑方面的帮助，以便只要他们有一张照片或选择上传的文件，表格就有效，上传也会有效。当我同时拥有照片和文档时，它总是有效，但当它只是一张照片或文档时，它似乎随机工作。这是我目前的代码：

def upload(request):
"""
Uploads document/photo

"""

if request.method == 'POST':

    form1 = DocumentForm(request.POST, request.FILES)
    form2 = PhotoForm(request.POST, request.FILES)
    if form1.is_valid() and form2.is_valid() :
        post1 = Document(user = request.user, document= form1.cleaned_data['document'], title = form1.cleaned_data['title'])
        post1.save()
        post2 = Photo(user = request.user, alias = request.user.username, img = form2.cleaned_data['img'], title = "")
        post2.save()
        return HttpResponse(template.Template('''
                    <html><head><title>Uploaded</title></head> <body>
                    <h1>Uploaded</h1>
                    </body></html>
                    '''
                    ).render( template.Context({}))
                )

    elif form1.is_valid():
            post1 = Document(user = request.user, document = form1.cleaned_data['document'], title = form1.cleaned_data['title'])
            post1.save()

            return HttpResponse(template.Template('''
                        <html><head><title>Uploaded</title></head> <body>
                        <h1>Uploaded</h1>
                        </body></html>
                        '''
                        ).render( template.Context({}))
                    )

    else:
        if form2.is_valid():
            post2 = Photo(user = request.user, alias = request.user.username, img = form2.cleaned_data['img'], title = "")
            post2.save()
            return HttpResponse(template.Template('''
                    <html><head><title>Uploaded</title></head> <body>
                    <h1>Uploaded</h1>
                    </body></html>
                    '''
                    ).render( template.Context({}))
                )


else:  
    form1 = DocumentForm() 
    form2 = PhotoForm()
return render_to_response('upload.html', {'form1': form1, 'form2':form2 }, context_instance=RequestContext(request))

我知道必须有更好的方法。任何帮助将不胜感激。感谢

你真的需要两种不同的形式吗？看起来你可能只想要一个带有两个文件字段的表单。

if request.method == 'POST':

    form = DocumentAndPhotoForm(request.POST, request.FILES)
    if form.is_valid():
        if form.cleaned_data.get('document'):

            post1 = Document(user = request.user, document= form1.cleaned_data['document'], title = form1.cleaned_data['title'])
            post1.save()

        if form.cleaned_data.get('img'):
            post2 = Photo(user = request.user, alias = request.user.username, img = form2.cleaned_data['img'], title = "")
            post2.save()


        return HttpResponse(template.Template('''
                <html><head><title>Uploaded</title></head> <body>
                <h1>Uploaded</h1>
                </body></html>
                '''
                ).render( template.Context({}))
            )

return render_to_response('upload.html', {'form': form },      context_instance=RequestContext(request))

DocumentAndPhotoForm上的文件字段需要传入null=True and blank=True个参数。

Django：在同一表单上上传照片和word文档无法正常工作
