How to Develop an App in Odoo


If you’re looking to build a custom business app, Odoo is one of the best platforms out there. Known for its modular structure and open-source foundation, Odoo makes it easy to develop powerful, scalable applications tailored to your specific business needs. Whether you're an entrepreneur or a developer, understanding the process of Odoo development can help you create robust apps quickly and efficiently.

Let’s dive into a step-by-step guide on how to develop an app in Odoo.

Step 1: Set Up Your Odoo Development Environment

Before anything else, you need to set up your development environment. Start by installing the required dependencies like Python, PostgreSQL, and Git. Then download the Odoo source code from GitHub.

Create a virtual environment, install dependencies, and configure your database. This sets the foundation for smooth Odoo development work.

Step 2: Create a New Custom Module

In Odoo, apps are developed as modules. Navigate to the “addons” directory and create a new folder for your module. Inside this folder, create essential files like:

  • __manifest__.py: Defines the module's metadata (name, version, author, etc.)

  • __init__.py: Initializes the module

  • models/: A folder where you define the business logic using Python

  • views/: Contains XML files for UI design

  • security/: Manages access rights

This structure is the backbone of any custom Odoo app.

Step 3: Define Your Models

Within the models directory, create your Python file (e.g., models.py) and define your models using Odoo’s ORM (Object-Relational Mapping). For example, if you’re creating a “Task Management” app, define a task model with fields like title, deadline, and status.

Odoo’s ORM simplifies database interaction and lets you focus on building smart features instead of worrying about SQL queries.

Step 4: Design the User Interface

In the views folder, create XML files to build menus, forms, tree views, and actions. These files link your backend logic with the frontend, making your app usable via Odoo’s web interface.

Customize the UI to suit your users’ workflow. This is where Odoo development really shines — the framework allows full control over design and layout.

Step 5: Add Security and Access Rights

Every good app needs proper access control. Define roles, groups, and permissions in XML and CSV files inside the security folder. This ensures users only see and interact with features they’re authorized to use.

Step 6: Install and Test Your App

Once everything is set up, go to the Odoo dashboard, update the app list, and install your custom module. Test all features to ensure smooth functionality. Debug if necessary, and fine-tune the app based on real-world use.

Final Thoughts

Odoo development offers a flexible and efficient way to build custom apps for any industry. With a solid understanding of its framework and modular system, you can create feature-rich solutions that enhance your business operations. Ready to start building?
