In this tutorial I am going to show you how to write binary field data into zip file and download it on Odoo button click event.

Write binary data into zip file and downlaod it on button click in odoo

Download zip file on button click in Odoo

The scenario is we have an attachment or file (in binary format) in our database (PostgreSQL) and we want to download that file or attachment in .zip or .rar extension on button click. To do that I am going to use python library named "zipfile". This is python standard library, so we don't need to install it explicitly.

      dear there is no difference, actually self.attachment is a binary field name nothing else...
      attachment = fields.Binary(string='Attachment')
