由于数据库的upload_to功能，有时不能满足每次上传灵活自定义的需求，
基于DEF的上传，有时不能满足基于CLASS的视图要求，
于是，只好慢慢用土法实现。
当然，首先，要使用上传功能时，form里的这个东东enctype="multipart/form-data"，必须加。
然后，关键实现如下：
class UploadView(FormView):
template_name = 'upload.html'
form_class = UploadFileForm
def form_invalid(self, form):
return self.render_to_response(RequestContext(self.request, {'form': form}))
def form_valid(self, form):
file_path = form.cleaned_data['file_path']#这里保存着我们要的东东哟
deployversion_upload_done(file_path)
return HttpResponseRedirect(reverse("list"))
def deployversion_upload_done(upload_file):
file_with_path = "这里可以传变量或自定义目录哟" + str(upload_file)
with open(file_with_path, 'wb+') as destination:
for chunk in upload_file.chunks():
destination.write(chunk)
