用html和python处理文件提交 [英] Handling file submissions with html and python

问题描述

我正在尝试创建一个可以处理来自用户的视频文件上传的表单，但是我遇到了一些问题。我试图避免为此建立一个模型表单，因为我不会将文件保存到我的数据库长期。我只是想把它交给服务器，以便我可以把它提交给YouTube。我的html是：

I'm trying to create a form that will handle video file uploads from the user, but I'm running into a bunch of problems. I am trying to avoid building a model form for this because I won't be saving the file to my database long term. I just want to get it to the server so that I can submit it to youtube. The html I have is:

<form method='post' action='/new/' enctype="multi-part/form-data">{% csrf_token %}
    <input type='file' name='file' id='file'/>
    <input type='submit' />
</form>

然后视图会尝试处理文件，如下所示：

and then the view attempts to handle the file like so:

def create_video(request):
    if request.method == 'POST':
        video = request.POST['file']

        command=subprocess.Popen('youtube-upload --email=' + email + ' --password=' + password + '--title=' + title + ' --description=' + description + ' --category=Sports ' + video, stdout=subprocess.PIPE)

        vid = command.stdout.read()

        # do stuff to save video instance to database
        return show_video(request, video.id)
    else:
        form=Video()
    return render_to_response('create_video.html', RequestContext(request, locals()))

注意：youtube-upload是一个使用该给定命令将视频上传到youtube的python模块。

note: youtube-upload is a python module to upload videos to youtube with that given command.

所以对于初学者，当我从前端提交表单django发送消息说在< QueryDict：...

So for starters when I submit the form from the front end django sends a message saying "Key 'file' not found in <QueryDict:...

中找不到密钥文件，所以它会正确提交的其他视图正确处理文件？

and given that I fix the form so that it will submit properly is the rest of the view properly handling the file?

推荐答案

请求。 POST 不包含文件上传信息。您需要使用 request.FILES 。

request.POST doesn't contain file upload information. You need to use request.FILES.
