Herencia Templates Qweb
Algó muy útil y necesario para el desarrollo Odoo es la herencia, en mas de una ocasión esto nos ah salvado y ayudado para adaptar el Sistema, Qweb Reports no se queda atras e implementa la herencia de las Vistas que son las que generan nuestros Reportes, para elló utilizaremos la herramienta xml Xpath.
La forma de heredar es simple, utilizaremos el ID de la vista del reporte, tal cual lo hacemos con las Vistas de Formulatios y añadimos, modificamos ó reemplazamos un elemento.
Ejemplo Herencia Xpath en Qweb Reports
Vamos a heredar el reporte de Albaran y modificar el cuerpo del Reporte, por ejemplo añadimos una tabla para tener un espacio para firmar la entrada y salida de Almacen.
El codigo para añadir estas firmas es:
<table border="0" style="border-collapse:collapse;color:000000;width:100%" cellpadding="3" cellspacing="3">
<tr>
<td class="text-center" >________________________</td>
<td class="text-center" >________________________</td>
</tr>
<tr >
<td class="text-center" >
<strong>Nombre y Firma Entrega</strong>
</td>
<td class="text-center" >
<strong>Nombre y Firma Recepcion</strong>
</td>
</tr>
</table>
Heredamos la vista Qweb por medio del ID:
<template id="report_header_custom" inherit_id="stock.report_picking">
<xpath expr="//div[@class='page']" position="replace">
<div class="page">
Aquí va nuestro código .......
</div>
Al final así quedo mi nueva Vista para el Reporte de Albarán:
<!-- Template Final -->
