Odoo 13 压缩表单中的所有二进制字段并下载它

如何解决Odoo 13 压缩表单中的所有二进制字段并下载它

我有一个表单视图，其中有 5 个二进制字段，即 4 个是图像，1 个是音频。我需要压缩这些字段，用户应该能够从树视图中为选定的记录下载它，可能是通过单击按钮或操作下拉列表中的新选项。有没有可能的解决方案？任何帮助，将不胜感激。提前致谢。

我在表单视图中使用了两个按钮进行了尝试，一个用于生成 zip，一个用于下载，但我需要从树视图中下载相同的多个记录。

crop_stage = request.env['crop.stage'].sudo().search([('id','=',self.id)])

    for rec in crop_stage:

        shutil.make_archive(src_path,'zip',src_path)

        print('End')
