Mastering Essential Odoo Development Skills

In this section explore Odoo's report engine and ability to produce PDF files. We begin by looking at an overview of Odoo's reporting engine and learn how to navigate Odoo's source code to find examples of Odoo report templates and menus. 

Some installations of Odoo have issues with having the correct version of Odoo's print engine Wkhtmltopdf that converts Odoo qWeb templates into a PDF file. In this video you will learn how to patch Odoo to handle changes with the reporting engine.

Finally we look at how to loop through Odoo models and data sets to create more complex reports in Odoo.

Steps to creating a custom report in Odoo

If you are new to reporting in Odoo then this course will certainly help you understand the basics and framework for creating a report in Odoo. From a development perspective the first steps are to understand the models that you need to pull data from. In our video example we demonstrate how to pull data from the product model that you have developed with your own custom fields.  

After you know the models you need to reference you can use the qWeb code to display the fields you need on your report. 

Creating a custom Odoo Report  

Source code from the video tutorial

Creating a custom report in Odoo is much like creating any other view. Use the <template> keyword to wrap your report. The <t> tag is used to separate elements in your report.

Here is a code example that you can use to help you get started. The video tutorial above walks you through developing the custom report and integrating it with a menu in Odoo step by step.

<template id= "product.nutrition">
    <t t-call="report.html_container">
         <t t-foreach="docs" t-as = "o">
             <t t-call ="report.external_layout">
                 <div class="page" >
                     <div class="oe_structure" />
                     <h1>Nutrition Report</h1>
                     <h2>Product Name: <span t-field=""/>

Understanding the qWeb Tags and attributes

Each tag in qweb is used by the engine to process the report. Here are some of the more important tags we are using to build our custom report.


The template tag is the main wrapper for your report. 
The t-call attribute tell the qweb engine to call another report template and process it. This is the main mechanism to create sub-reports. To create complex reports in Odoo you will need to use t-call so that you can process multiple datasets.
The t-foreach attribute loops through the data structure you provide. In this example the dataset is "docs". Each record is then placed into the variable specified in t-as. In this case the variable is  "o".
Use t-field to specify the field from the dataset you wish to display on the report.
