Some of the approaches and assumptions here may not be correct if you have more professional Odoo experience than I do. Take it as a war story, not a best practice guide.</p> </blockquote> <h2 id="tldr" class="anchor-link"><a href="#tldr">TL;DR</a></h2> <p>Odoo 18&rsquo;s core <code>hr_attendance</code> module works fine. The overtime computation, the unique constraint, the <code>_update_overtime()</code> logic — all correct. The problem? A third-party custom module that overrides <code>create()</code> and <code>write()</code> on <code>hr.attendance</code> <strong>without understanding the side effects</strong>. It triggers <code>_update_overtime()</code> multiple times for the same day, causing a duplicate key violation. Your attendance record gets rolled back. The employee&rsquo;s scan vanishes.</p>
