This module is a technical module with the purpose of easing the export
of image thumbnails to a search engine index.
When you export images to an index, you may want to ensure that the
images are exported in a format and size that is suitable for the
application that will consume the index.
This module depends on the
fs_image_thumdbnail
module. This last one provides a method and a mixin used to generate
thumbnails from a FSImageValue object.
As specified, this module will not add any new features by itself once
installed. As a developer, you can depend on this module to benefit from
a set of specialized methods that can be used to get and generate
thumbnails from an image you want to index.
Behind the scenes, this module extend the se.indexable.recor model
by adding 2 new methods:
- _get_or_create_thumbnails_for_multi_images: This method is used
to get or create thumbnails for a set of images.
- _get_or_create_thumbnails_for_image: This method is used to get
or create thumbnails for a single image.
Thanks to these methods, you can easily generate thumbnails for images
stored into odoo through three different ways:
- A relational field referencing record inheriting from
fs.image.relation.mixin.
- An odoo’s Image field.
- An FSImage field.
The sizes of the thumbnails generated by these methods are configured
through the creation of a new record into the se.thumbnail.size
model. This model allows you to define the size of thumbnails by search
engine backend, model and field. For example, you can define that you
want to generate thumbnails of size 100x100 for all the images
stored into the product.template model and the image field when
you export them to the opensearch_xyz backend. In this way, you can
easily define different thumbnail sizes for different search engine
backends, models and fields according to your needs.
Thumbnails are always retrieved and generated for one image and a
specific base_name. The base name is used as a key to identify the
thumbnails from an image related to a usage and also as base name for
the file name of the thumbnails generated. By default, the base_name
is computed from the display name of the record that contains the image
to ensure a good SEO. To avoid problems with special characters, the
base_name is normalized before being used.
Here is an example of how to use these methods:
from odoo import models, fields
from odoo.addons.fs_imeage.fields import FSImage
class ProductImageRelation(models.Model):
_name = "product.image.relation"
_inherit = ["fs.image.relation.mixin"]
name = fields.Char(required=True)
product_id = fields.Many2one(
"product.product",
required=True,
ondelete="cascade",
)
class ProductProduct(models.Model):
_name = "product.product"
_inherit = ["se.indexable.record", "product.product"]
name = fields.Char(required=True)
image = fields.Image(required=True)
image_ids = fields.One2many(
"product.image.relation",
"product_id",
string="Images",
)
fs_image = FSImage(required=True)
# A creation is always done for a given se.index record.
index = self.env["se.index"].browse(1)
product = self.env["product.product"].browse(1)
# Get or create thumbnails for a single image
for (thumbnail_size, thumbnail) in product._get_or_create_thumbnails_for_image(
index,
field_name="image",
):
# Do something with the thumbnail
print(f"Thumbnail for image with size {thumbnail_size.display_name} "
"is available at url {thumbnail.image.url}")
# Get or create thumbnails for a single image
for (thumbnail_size, thumbnail) in product._get_or_create_thumbnails_for_image(
index,
field_name="fs_image",
):
# Do something with the thumbnail
print(f"Thumbnail for fs_image with size {thumbnail_size.display_name} "
"is available at url {thumbnail.image.url}")
# Get or create thumbnails for a set of images
thumbnails_by_image = product._get_or_create_thumbnails_for_multi_images(
index,
field_name="image_ids",
)
for (image, thumbnails) in thumbnails_by_image.items():
for (thumbnail_size, thumbnail) in thumbnails:
# Do something with the thumbnail
print(f"Thumbnail for image {image.name} with size "
"{thumbnail_size.display_name} is available at url "
"{thumbnail.image.url}")
