Allow multiple images for database objects

Project description

Beta License: AGPL-3 OCA/server-tools Translate me on Weblate Try me on Runboat

This module extends the functionality of any model to support multiple images (a gallery) attached to it and allow you to manage them.

Table of contents


This module adds abstract models to work on. Its sole purpose is to serve as base for other modules that implement galleries, so if you install this one manually you will notice no change. You should install any other module based on this one and this will get installed automatically.


To manage all stored images, you need to:

  • Go to Settings > Technical > Multi images.

… but you probably prefer to manage them from the forms supplied by submodules that inherit this behavior.


To develop a module based on this one:

  • See module product_multi_image as an example.

  • You have to inherit model base_multi_image.owner to the model that needs the gallery:

    class MyOwner(models.Model):
        _name = ""
        _inherit = ["", "base_multi_image.owner"]
        # If you need this, you will need ``pre_init_hook_for_submodules`` and
          ``uninstall_hook_for_submodules`` as detailed below.
        old_image_field = fields.Binary(related="image_main", store=False)
  • Somewhere in the owner view, add:

            'default_owner_model': '',
            'default_owner_id': id,
  • If the model you are extending already had an image field, and you want to trick Odoo to make those images to multi-image mode, you will need to make use of the provided ~.hooks.pre_init_hook_for_submodules and ~.hooks.uninstall_hook_for_submodules, like the product_multi_image module does:

        from odoo.addons.base_multi_image.hooks import (
    except ImportError:
    def pre_init_hook(cr):
        """Transform single into multi images."""
        pre_init_hook_for_submodules(cr, "product.template", "image")
        pre_init_hook_for_submodules(cr, "product.product", "image_variant")
    def uninstall_hook(cr, registry):
        """Remove multi images for models that no longer use them."""
        uninstall_hook_for_submodules(cr, registry, "product.template")
        uninstall_hook_for_submodules(cr, registry, "product.product")

Known issues / Roadmap

  • OS file storage mode for images is meant to provide a path where Odoo has read access and the image is already found, not for making the module store images there. It would be nice to add that feature though.
