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.

## 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() ++
