Django save_model文件尚未上传

Question

def save_model(self, request, obj, form, change):

在这个处理程序中我可以获取上传文件的名称，但文件本身尚未上传，所以我无法对其进行任何操作，可以有办法强制django上传该文件在这个save_model处理程序中？为了对它做一些操作

def save_model(self, request, obj, form, change):

    obj.save()
    super(FileAdmin, self).save_model(request, obj, form, change)
    //here i am getting the file name its there, but the file itself is not uploaded
