Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I am migrating a database with thousands of products. Trying to export large numbers of images using the Odoo web interface is not possible due to resource limits on the server.
How can I export the external ids and the product images directly from the Odoo database?
Looking at openerp/osv/orm.py in _get_external_ids() we can see that the external ids are stored in "ir_model_data" and can be tied to the models using "ir_model_data"."model" and "ir_model_data"."res_id". So to dump product external ids and images to a CSV:
copy (select "ir_model_data"."module" || '.' || "ir_model_data"."name" as "id", encode("product_product"."image",'base64') as "image" from "product_product" left join "ir_model_data" on (("ir_model_data"."model" = 'product.product') and ("product_product"."id" = "ir_model_data"."res_id")) where ("product_product"."image" is not null)) to '/tmp/product.product.images.csv' with csv header;
Or to pipe data from the source server to another server, connect from the remote server to the source database using psql:
\copy (select "ir_model_data"."module" || '.' || "ir_model_data"."name" as "id", encode("product_product"."image",'base64') as "image" from "product_product" left join "ir_model_data" on (("ir_model_data"."model" = 'product.product') and ("product_product"."id" = "ir_model_data"."res_id")) where ("product_product"."image" is not null)) to 'product.product.images.csv' with csv header;
Alternatively, I suppose it would be possible to:
But exporting the external id directly, as described above, would in many cases be preferable.
Another alternative would be to script oerplib to stream data from an old database to a new database.
Hi, i know this is kind of an old post but i would like to know where did you found the binaries for the images, im performing a similar export from odoo 12 and the interface export of images is broken
i used some similar queries to yours in this post but to no avail, there are no images in product_templates or product_product.
after some research i found out that for odoo 12 images are saved in ir_attachement in the field: datas_fname.
so i got this query
Select "id", "res_name", "datas_fname" from ir_attachment WHERE res_model = 'product.template' and "datas_fname" is not null;
and the result is this sample:
https://docs.google.com/spreadsheets/u/7/d/1QR_HTSiYxUXOSl-2nS0MaDY7QHRMbux-43RhbB1eYak/edit?usp=sharing
there are no binaries in this table.
i made:
Select * from ir_attachment WHERE res_model = 'product.template' and res_field = 'image' and 'db_datas' is not null
to check all the fields from the table and got this other data set.
https://docs.google.com/spreadsheets/d/1g1zZrTLu56MU7S5O5nzg-QQtsLa8QaE7jflddnRb9Wo/edit?usp=sharing
where i got: no binaries at all
where di you got the binaries for your export?
kindly thank you very much.
Apologies for my ignorance but the where do you run the copy instruction? On a terminal, on postgresql, on python?
From a terminal, run psql to access your PostgreSQL database, then run the \copy command from psql. And of course test before you do anything in a production environment.
