+
+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.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Usage
+=====
+
+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()

+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="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"

+                </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>
+        </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 (
