Summary

We created a new module from the start, covering the most frequently used elements in a module: models, the three basic types of views (form, list, and search), business logic in model methods, and access security. We also learned about security access control, including record rules, and how to create web pages using web controllers and QWeb templates.

In the process, we got familiar with the module development process, which involves module upgrades and application server restarts to make the gradual changes effective in Odoo.

Always remember, when adding model fields, an upgrade is needed. When changing Python code, including the manifest file, a restart is needed. When changing XML or CSV files, an upgrade is needed; also, when in doubt, do both: restart the server and upgrade the modules.

In the next chapter, you will go deeper into models, and explore everything they have for us.
