DMS — LibreOffice Preview

+ +

Beta License: LGPL-3 OCA/dms Translate me on Weblate Try me on Runboat

+

Adds in-browser preview of office file formats (Word, Excel, PowerPoint, +OpenDocument, RTF) to OCA DMS by converting them to PDF on the server +with a headless LibreOffice subprocess. The converted PDF is cached as a +child ir.attachment of the source dms.file and served via the +existing side-pane preview registry (dms.preview_handlers), so the +browser’s native PDF viewer renders the result with no new UI code.

+

Without this module, office files in DMS fall back to a download-only +card. Install this module on any deployment where LibreOffice can be +installed system-wide and you don’t need full in-browser editing (use +dms_onlyoffice for that).

+

Table of contents

+ +
+

Installation

+
+

System dependencies

+

LibreOffice must be installed on the Odoo server. On Debian / Ubuntu:

+
+apt-get install libreoffice fonts-noto fonts-liberation
+
+

The fonts-noto and fonts-liberation packages are recommended +even if your container already has a font set — headless LibreOffice +falls back to ugly substitutes when common fonts are missing, which +produces unreadable PDFs for typical office documents.

+

Once LibreOffice is on the PATH, install this module as usual. The +preview is lazy: nothing converts until the first time a user opens an +office file in the DMS side-pane. Subsequent opens of the same file +(same write_date) hit the ir.attachment cache.

+
+
+
+

Usage

+

No configuration required. With LibreOffice on the server and this +module installed, opening any office file (.doc{x}, .odt, +.xls{x}, .ods, .ppt{x}, .odp, .rtf) from the DMS +kanban or list view shows the rendered PDF in the side-pane preview.

+

The first open takes 1–5 seconds (LibreOffice conversion); subsequent +opens hit the cached attachment and feel instant. If the source file +changes (new content, new name, etc.), the cache invalidates and the +next open triggers a fresh conversion.

+

If LibreOffice fails to convert a file (corrupt source, unusual format +variation), the side-pane shows a brief error message. The original file +is always downloadable via the side-pane toolbar’s Download button +regardless of preview success.

+
