Document Share Public
This app allows users to share the documents attached along with Odoo records via a public URL. The screen shows a sale order record with two attachments.
At the bottom of the record, in the chatter area, will appear the new link “Attachment Link”.
The Action will open a pop up where users can see the list of attachments related to the record(sale order).
Clicking on the link against selected document will open a new window with public URL of the attachment(document).
The URL, from any browser, will open the document directly.
Please refer link to the module in Odoo Apps.
