Adding custom settings options

In Odoo, you can provide optional features through the Settings options. The user can enable or disable this option at any time. We will illustrate how to create Settings options in this recipe.

Getting ready

In previous recipes, we have added buttons so that non-librarian users can borrow and return books.

In this recipe, we will use the same my_library module from the previous recipes.

       <record id="group_self_borrow" model="res.groups">
