How To Develop Odoo Module

How To Articles

Today, I am eager to disclose my own journey and knowledge regarding the creation of an Odoo module. Being a developer who has had significant experience with Odoo, I have recognized its strength and flexibility in constructing tailored business programs. In this piece, I will walk you through the steps and offer valuable insights on developing an Odoo module.

What is Odoo?

Before we dive into the development process, let’s briefly discuss what Odoo is. Odoo is an open-source ERP (Enterprise Resource Planning) software that offers a suite of business applications for various sectors, including CRM, e-commerce, inventory management, and more. It provides a modular structure that allows developers to extend its functionality by creating custom modules.

Getting Started

To begin developing an Odoo module, you first need to have a development environment set up. I recommend using a Virtual Machine or Docker to ensure a clean and isolated environment. Once you have your development environment ready, you can proceed with the following steps:

  1. Create a new directory for your module, preferably within the Odoo addons directory.
  2. Inside your module directory, create a manifest file with the extension “.manifest”. This file serves as the entry point for your module and provides essential information about it, such as the module name, version, and dependencies.
  3. Next, create a Python file with the same name as your module. This file will contain the main code for your module.
  4. In your module’s Python file, define a class that inherits from the “odoo.models.Model” class. This class will represent your custom model and will define its fields, methods, and behaviors.
  5. Within your model class, define the necessary fields using Odoo’s field types, such as “CharField” for a text field or “IntegerField” for an integer field.
  6. Implement the desired methods in your model class. Odoo provides a variety of methods that you can override to customize the behavior of your module, such as “create”, “write”, and “unlink”.
  7. Once you have defined your model and its associated methods, don’t forget to add your module to the Odoo database by updating the manifest file with the appropriate XML code.

Testing and Refining

After completing the initial development of your Odoo module, it’s crucial to thoroughly test it to ensure its functionality and compatibility with other modules. Odoo provides a testing framework that allows you to write automated tests for your module. By writing comprehensive test cases, you can catch any potential bugs or issues early on and make necessary refinements to your code.

Community and Documentation

The Odoo community is vast and supportive, making it an excellent resource for developers. If you encounter any difficulties during the development process or have questions about specific features, don’t hesitate to reach out to the community for help. The official Odoo documentation is also a valuable source of information and provides detailed explanations, tutorials, and examples to help you develop your Odoo module effectively.


Developing an Odoo module can be a challenging yet rewarding experience. By following the steps outlined in this article and leveraging the resources available in the Odoo community, you can create powerful and customized business applications tailored to your specific needs. Remember to test your module thoroughly and continuously refine it based on user feedback. Happy coding!
