Attachment Url

Use attachment URL and upload data to external storage

The module allows to use url in Binary fields (e.g. in product images). It provides the possibility for uploading files to external storage (ftp, s3, some web server, etc) and uses url instead of transfer binary data between odoo server and client that, in turn, allows to reduce the load on server.
E.g., for uploading files to S3 you can use our module ir_attachment_s3: https://apps.odoo.com/apps/modules/11.0/ir_attachment_s3/

How it works

As an example go to Sales → Products menu and open or create new item. Upload any image to the product.


  • Go to Settings → Database Structure → Attachments menu.
  • Add custom filter: Resource Field is set
  • Switch to list view and open the created attachment items: image_small, image_medium, image

In the form that appears change 'Type' to URL and set url in the 'Url' field. As a result you can see related image in your product.

ir_attachment_url_fields context

In order to store urls instead of binary data in binary fields, you can use ir_attachment_url_fields context. For example, you need to create ir.ui.menu record which has web_icon_data fields, defined as Binary field. To store url to web_icon_data field you need to define context ir_attachment_url_fields="ir.ui.menu.web_icon_data" and set value of the field. See test cases as detailed examples.

In order to store multiple fields as urls, define context like this ir_attachment_url_fields="model.name.field1,another.model.name.field2".
