How To Edit Odoo Source Code

How To Articles

Modifying the Odoo source code can be an effective approach to tailor and improve your Odoo installation to suit your individual business requirements. In this article, I will share my personal encounter and supply a detailed tutorial on how to modify the Odoo source code.

Introduction to Odoo Source Code

Odoo is an open-source ERP software that allows businesses to manage various aspects of their operations, such as sales, inventory, accounting, and more. The source code of Odoo is written in Python and is available for customization and modification.

Before diving into editing the source code, it’s essential to have a basic understanding of Python and Odoo’s architecture. Familiarize yourself with the Odoo framework, its modules, models, views, and controllers.

Step 1: Setting Up the Development Environment

The first step is to set up a development environment for working with Odoo source code. Here’s what you need to do:

  1. Install Python: Make sure you have Python installed on your system. You can download the latest version of Python from the official Python website.
  2. Install Odoo: Download the Odoo source code from the official Odoo website and follow the installation instructions for your operating system.
  3. Set Up a Virtual Environment: It’s a good practice to set up a virtual environment to isolate your development environment from your system’s Python installation. Use tools like virtualenv or conda to create a virtual environment.
  4. Install the Required Dependencies: Odoo has several dependencies that need to be installed. Use pip, the Python package manager, to install the required packages mentioned in the Odoo documentation.

Step 2: Understanding the Source Code Structure

Before making any changes to the Odoo source code, it’s essential to understand its structure. The source code is organized into modules, each with its specific functionality.

Modules are stored in the “addons” directory of your Odoo installation. Each module has its directory, which contains Python files, XML views, and other related files.

To find the module you want to edit, navigate to the relevant directory in the “addons” folder. Open the Python file containing the code you want to modify.

Step 3: Making Changes to the Source Code

Once you have identified the module and the specific Python file you want to edit, you can make changes according to your requirements. Here are some common scenarios:

  • Modifying Existing Code: You can edit the existing code to add new functionality, customize the behavior of an existing feature, or fix a bug. Locate the relevant function or method and make the necessary changes.
  • Adding New Functionality: If you want to add new functionality, you can create a new function or method within the appropriate class or module.
  • Modifying XML Views: Odoo uses XML files for defining the user interface. If you want to modify the way a view looks or add new elements, locate the XML file responsible for that view and make the necessary changes.

Remember to follow best practices while editing the source code, such as maintaining proper indentation, using meaningful variable names, and adding comments to explain your changes.

Step 4: Testing Your Changes

After making the required changes to the source code, it’s crucial to test your changes to ensure they work as expected and do not introduce any errors or issues.

Restart your Odoo server and navigate to the corresponding module or feature in your Odoo instance. Verify that your changes have been successfully applied and are functioning correctly.


Editing Odoo source code can be a powerful way to customize and extend the functionality of your Odoo instance. By following the steps outlined in this article, you can confidently make changes to the source code and tailor Odoo to meet your specific business requirements.
