Creating Custom Reports - Mastering Odoo 9 Development Part 8
Section 8: Odoo uses a powerful reporting engine that allows you to create custom reports from within Odoo. In this video you learn how to create an Odoo report template, call the report for a menu, and learn how to use qWeb to loop through datasets to report information. Even better, you can build on these fundamentals and be prepared for more advanced web interfaces.
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="o.name"/>
</div>
</t>
</t>
</t>
</template>
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.
| <template> | The template tag is the main wrapper for your report. |
| t-call | 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. |
| t-foreach | 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". |
| t-field | Use t-field to specify the field from the dataset you wish to display on the report. |

Understanding Odoo Class Master Courses
With this new course we will be better identifying our more important video courses that we release on Odoo Class. These courses are foundation courses that have many hours of content to teach you the fundamentals of Odoo. Like our Odoo 9 Essentials course, this course provides you the fundamentals you need for developing Odoo 9 Applications. Future Odoo developer videos and courses will build on these essential Odoo developer topics.
Get Started Learning to Develop Odoo Applications
The entire purpose of this video course is to give you everything you need to get started developing applications in Odoo. Even if you don't have Odoo running on your computer... we have you covered and show you how to install a virtual Ubuntu Desktop right on your Windows machine. See step by step how to install Odoo with source code from git hub. See behind the scenes of the Odoo application and peek into how the Odoo framework fits together.
