Atachment Category

This module adds a way to classify the documents stored in Odoo. You can create document categories, organise them in a parent/child tree, and assign one or more categories to any attachment.

Where it appears: - A new "Attachment Categories" menu lets you create and manage the category tree. - On the attachment form, a tags field lets you pick categories for a document. - The attachment list and search views also show the categories, so you can filter documents by category.

Business rules and automatic behaviour: - Category names are shown with their full path (for example "Parent/Child") based on the parent category. - Each category form shows a counter button with the number of attachments in that category, including attachments in its child categories; clicking it opens the list of those documents. - A category cannot be deleted while attachments still use it.

It touches the attachment model (ir.attachment) and introduces a new category model (ir.attachment.category). Access is granted to all internal users.
