1. Go to *Settings \> Technical \> Database Structure \> Attachments*
and select some files.
2. Go to *Actions \> Download* and a zip file containing the selected
files will be downloaded.
\## 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:
<odoo>
<!--
add a button on list view to download all attachement present
on the given transfert
-->
<record id="vpicktree" model="ir.ui.view">
<field name="inherit_id" ref="stock.vpicktree"/>
<field name="name">stock.picking.tree download attachments</field>
<field name="model">stock.picking</field>
<field name="arch" type="xml">
<field name="json_popover" position="after">
<button name="action_download_attachments"
type="object"
icon="fa-download"
string="Download attachment(s)"
aria-label="Download Proof documents"
class="float-right"/>
</field>
</field>
</record>
<!--
Add "Download attachments" item in the Action menu when
multiple records are selected
-->
<record id="action_download_picking_attachements" model="ir.actions.server">
<field name="name">Download attachments</field>
<field name="model_id" ref="stock.model_stock_picking"/>
<field name="binding_model_id" ref="stock.model_stock_picking"/>
<field name="binding_view_types">list</field>
<field name="state">code</field>
<field name="code">
action = records.action_download_attachments()
</field>
</record>
</odoo>
> [!NOTE]
> Even you will be able to generate a zip file with multiple document
> with the same name it's advice to overwrite \_compute_zip_file_name to
> improve the name. When a slash (/) is present in the path it will
> create a directory. This example will create a directory per
> stock.picking using its name:
>
> class IrAttachment(models.Model):
> _inherit = "ir.attachment"
>
> def _compute_zip_file_name(self):
> self.ensure_one()
> if self.res_model and self.res_model == "stock.picking":
> return (
> self.env[self.res_model]
> .browse(self.res_id)
> .display_name.replace("/", "-")
> + "/"
> + self.name
> )
> return super()._compute_zip_file_name()
