使用save_FOO方法时会让你输入一个文件名的。upload_to只是设置了目录，没有文件名。

看db-api的文档：

save_FOO_file(filename, raw_contents)

For every FileField, the object will have a save_FOO_file() method,
where FOO is the name of the field. This saves the given file to the
filesystem, using the given filename. If a file with the given
filename already exists, Django adds an underscore to the end of the
filename (but before the extension) until the filename is available.
