Odoo provides the developer with out-of-the-box modularity. Its powerful framework helps the developer to build projects very quickly. There are various characters in the Odoo ecosystem that you should be familiar with before starting your journey of becoming a successful Odoo developer.
Odoo ecosystem
Odoo editions
Odoo comes with two editions. The first is the Community Edition, which is open source, and the second is the Enterprise Edition, which has licensing fees. Unlike other software vendors, Odoo Enterprise Edition is just a bunch of advance applications that adds extra features/apps in the Community Edition. Basically, Enterprise Edition runs on top of the Community Edition. The Community Edition comes under the Lesser General Public License v3.0 (LGPLv3) license and comes with all of the basic Enterprise resource planning (ERP) applications, such as sale, Customer Relationship Management (CRM), invoicing, purchase, website builder, and so on. Alternatively, Enterprise Edition comes with the Odoo Enterprise Edition License, which is a proprietary license. Odoo Enterprise Edition comes with advanced features such as full accounting, studio, Voice over Internet Protocol (VoIP), mobile responsive design, e-sign, marketing automation, and delivery and banking integrations. Enterprise Edition also provides you with unlimited bugfixes. The following diagram shows that Enterprise Edition depends on the Community Edition, which is why you need Community Edition to use Enterprise Edition:
You can see a full comparison of both editions here: https://www.odoo.com/page/editions.
Odoo has the largest number of community developers, which is why you will find a large number of third-party apps (modules) on the app store. Most of the free apps use an Affero General Public License version 3 (AGPLv3). You cannot use the proprietary license on your app if your application has dependencies on such apps. Apps with an Odoo proprietary license can be developed only on modules that have LGPL or other proprietary licenses.
Git repositories
The whole code base of Odoo is hosted on GitHub. You can post bugs/issues for stable versions here. You can also propose a new feature by submitting Pull Requests (PR). There are several repositories in Odoo; see the following table for more information:
| Repositories | Purpose |
| https://github.com/odoo/odoo | This is the Community Edition of Odoo. It's available publicly. |
| https://github.com/odoo/enterprise | This is the Enterprise Edition of Odoo. It's available to official Odoo partners only. |
| https://github.com/odoo-dev/odoo | This is an Ongoing development repository. It's available publicly. |
Every year, Odoo releases one major (Long Term Support (LTS)) version and a few minor versions. Minor versions are mostly used in Odoo's online SaaS service, meaning that Odoo SaaS users get early access to these features. Major version branches have names such as 12.0, 11.0, and 10.0, while minor version branches have names such as saas-12.1, saas-11.1, and saas-11.2 on GitHub. The master branch is under development and is subject to change at any time. Consequently, it is advisable not to use this for production, since it might break down your database.
Runbot
Runbot is Odoo's automated testing environment. This pulls the latest branches from Odoo's Git repositories and creates the builds for the last four commits. Here, you can test all stable and in-development branches. You can even play with the Enterprise Edition and its development branches.
Every build has a different background color, which indicates the status of the test cases. A green background color means that all of the test cases run successfully and you can test that branch, while a red background color means that some test cases have failed on this branch and some features might be broken on that build. You can view the logs for all test cases, which show exactly what happens during installation. Every build has two databases. The all database has all of the modules installed on it, while the base database only has base Odoo modules installed. Every build is installed with basic demo data, and therefore you can test it quickly without extra configurations.
You can access runbot with from the following URL: http://runbot.odoo.com/runbot.
The following credentials can be used to access any runbot build:
- Login ID: admin Password: admin
- Login ID:demo Password: demo
- Login ID: portal Password: portal
This is a public testing environment, so sometimes it is possible that other users are using/testing the same branch that you are testing.
Odoo app store
Odoo launched the app store a few years back, and this was an instant success. Right now, there are over 15,000 different apps hosted there. In the app store, you will find lots of free and paid applications for different versions. This includes specific solutions for different business verticals, such as education, food industries, and medicine. It also includes apps that extend/add new features to existing Odoo applications. The app store also provides numerous beautiful themes for the Odoo website builder. In Chapter 4, Creating Odoo Add-On Modules, we will look at how you can set pricing and currency for your custom module.
You can access the Odoo app store via the following URL: https://www.odoo.com/apps.
Odoo community association
Odoo Community Association (OCA) is a non-profit organization that develops/manages community-based Odoo modules. All OCA modules are open source and maintained by Odoo community members. Under the OCA's GitHub account, you will find multiple repositories for different Odoo applications. Apart from Odoo modules, it also contains various tools, a migration library, accounting localizations, and so on.
Here is the URL for OCA's official GitHub account: https://github.com/OCA.
Official Odoo help forum
Odoo has a very powerful framework, and tons of things can be achieved just by using/activating options or by following specific patterns. Consequently, if you run into some technical issues or if you are not sure about some complex cases, then you can post your query on Odoo's official help forum. Lots of developers are active on this forum, including some official Odoo employees.
