Odoo 15 Development Essentials - Fifth Edition

Overview of this book

Odoo is fast becoming the reference open source platform for business applications thanks to the fact that it provides the infrastructure needed for developers to deliver software solutions for any business process quickly. Odoo's layered module approach makes it particularly effective for combining and extending features. This updated fifth edition is a tutorial-style introduction to essential Odoo development topics. The book starts by covering the development essentials for building business applications and takes you through Odoo installation and configuration, gradually transitioning from having no specific knowledge of Odoo to being ready for application development. You'll then learn how to develop your first Odoo application, while covering topics such as models and views. Later chapters will get you up to speed with using server APIs to add business logic, helping you lay a solid foundation for advanced topics. As you progress, you’ll get equipped to build and customize your applications and explore the new features available in Odoo 12 and beyond, such as in-memory ORM and computed writable fields. Finally, you’ll gain insights into building business logic and using the Odoo API to integrate with various applications. By the end of this book, you’ll be able to build business apps from scratch using the latest version of Odoo.

Managing Odoo databases

In the previous section, we learned how to create and initialize new Odoo databases from the command line. There are more commands worth knowing about to manage Odoo databases.

The Odoo server automatically creates the new PostgreSQL database for us. But we can also do that manually using the following command:

$ createdb MyDBName

This command can be used with the --template option to copy a database. The copied database can't have open connections for this to work. So, make sure that any Odoo instance using it has been stopped.

Tip

When running PostgreSQL in WSL, it may be the case that some operations display a message such as WARNING:  could not flush dirty data: Function not implemented. A workaround for this is to modify the PostgreSQL configuration file. For version 12, it should be at /etc/postgresql/12/main/postgresql.conf. Edit it at add two lines, fsync = off and data_sync_retry = true. Then, restart the PostgreSQL server...
