python - Django 进度条

Question

我正在使用 Django 上传文件并使用

subprocess

The job takes roughly 15 seconds to run, and rather than having the user think the page is frozen, I'd like to show a progress bar.

I can figure out the AJAX to update the progress bar, but what I don't know how to do is return an HttpResponse while subprocess is running. Perhaps threading is the solution? I don't have any experience there. Can someone give me some guidance?

Here's the view:

def start_job(request):
    if request.method == 'POST':
        form = UploadForm(request.POST, request.FILES)
        if form.is_valid() and form.is_multipart():
            save_file(form.cleaned_data['file'])
            subprocess.call(["Kitchen.bat", "/file:job.kjb"])
            return HttpResponseRedirect('/success/')
    else:
        form = UploadForm()
    return render_to_response('template.html')
