## 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()
