This module allows downloading multiple attachments as a zip file.
This also provide a helper class IrAttachmentActionDownloadMixin to be used by developer to add action method on models.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets users select several attachments in Odoo and download them together as a single ZIP file. It also gives developers a reusable helper so any record can offer a 'download all attachments' action.
This module adds a way to grab many documents at once instead of downloading them one by one.
On the Attachments screen (the ir.attachment list), a new server action called "Download" appears in the Actions menu. When you select one or more attachments and run it, Odoo checks that the selection contains only binary files; if not, it shows an error saying that only binary attachments are allowed. Otherwise it opens a download of a ZIP file named "attachments.zip" containing all the selected files. Each file keeps its own name inside the ZIP, and Odoo verifies you have read access to every attachment before packing it.
For developers, the module provides a reusable helper (a mixin) that can be added to any model. When used, it offers an action that looks at the attachments linked to the selected records: if none are found, a warning notification appears; if exactly one is found, that single file downloads directly; if several are found, they are bundled into a ZIP. The list of attachments to include can be customised by other modules.
No new menus or settings are added; the feature is reached through the standard attachment list and through buttons or actions added by modules that use the helper.

For developer
You can reuse the IrAttachmentActionDownloadMixin on your favorite models:
from odoo import models
class StockPicking(models.Model): _name = "stock.picking" _inherit = ["stock.picking", "ir.attachment.action_download"]
Then you can add an action button on list view line or on the action button (when multiple lines are selected) to download all files:
stock.picking.tree download attachments stock.picking
Download attachments
list code
action = records.action_download_attachments()
