Hi Izma,

In standard Odoo QWeb → wkhtmltopdf, you can’t reliably know final page numbers while rendering the same template (pagination happens only after wkhtmltopdf lays out the whole HTML, and your sections are dynamic).

Best-practice options:

1. Prefer PDF bookmarks instead of printed page numbers

   Use real headings (<h1>…</h1>, <h2>…</h2>) so the PDF viewer shows a clickable TOC (most users use this anyway). This avoids the “dynamic pages” problem entirely.

2. If you must print page numbers in the TOC: do a 2-pass / post-process approach

   • Pass 1: Render the PDF without the TOC.

   • Compute pages per section: split/measure pages (PyPDF2/pikepdf), track where each section starts.

   • Pass 2: Render a TOC page with the computed page numbers and prepend/merge it with the original PDF.

That’s the only robust way in Odoo when sections can expand/contract. Trying to do it “in pure QWeb” will always break for some data because pagination is not deterministic until PDF generation finishes.

I hope it works. Still, if you face any issue, then please feel free to contact: santosh.sekwadia@zehntech.com
