Develope an Odoo module
When developing an Odoo module the best way to get started is by adopting the OCA and Odoo S.A. best practices.
In this guide we give an overview of the practices.
Guidelines
Odoo S.A. provides a coding guideline https://www.odoo.com/documentation/16.0/de/contributing/development/coding_guidelines.html. The guide provides answers on how to almost every aspect of dveloping an Odoo module.
However, this guide is superseded by the OCA guidelines https://github.com/OCA/odoo-community.org/blob/master/website/Contribution/CONTRIBUTING.rst.
Repositories
The OCA organizes their modules into multiple collections / repositories. Visit https://github.com/OCA/ to get an overview.
A good example is the https://github.com/OCA/sale-workflow repo. It contains all sale related modules of the OCA.
Branches
For each Odoo version there is a git branch (..., 13.0, 14.0, 15.0, 16.0, ...). Modules are migrated between these branches for each major release.
Template
The OCA modules are bootstraped from https://github.com/OCA/oca-addons-repo-template. It uses Copier to scaffold a new module structure.
Odoo Linting
The Copier template ships a pre-commit configuration, that uses pylint for linting. Pylint is extended with https://github.com/OCA/pylint-odoo.
Python Linting
The template ships with a lot more quality tools. The config files for these tools are stored in the root of each repo and branch. Here is an example https://github.com/OCA/sale-workflow/blob/16.0.
The most important quality tools are:
