Daniel's Odoo 10 Development Essentials is the realization of my wishes from these sessions; the companion book I wish I could have given to the participants, to kick-start their first contact with Odoo. Chapter after chapter, he walks you through the creation of your first Odoo app, following best practices at every step. Starting with a solid development environment, you'll soon feel comfortable with your Odoo system, and quickly shape up your typical app. From the model groundwork upwards, you'll learn about each layer, including the latest website features and the integration mechanisms for third-party systems. Most importantly, your journey will include quick references for most important API areas, and before you know it, you will grasp the fundamental design properties of Odoo—minimalism, modularity, extensibility, and scalability. Understanding this will be an invaluable asset for any task you set out to accomplish, and is what sets apart good Odoo developers. This updated edition is a great reference for more experienced developers as well, as it focuses on Odoo 9 and 10, introducing a smarter framework, modern conventions and tools, and the removal of the first Odoo API. The book also includes a wealth of pro tips, acquired through years of experience, that should make a seasoned Odoo developer out of you in no time, without the extra gray hair! Last but not least, Daniel has a natural talent for this, so I promise you'll truly enjoy the Odoo 10 Development Essentials ride!
