# Reuse code with mixins If you need to interface with common Odoo features such as the chatter, you can rely on {doc}`mixins <../reference/backend/mixins>`. They are Odoo models exposing useful methods through inheritance. To learn and play with mixins, visit [this repository](https://github.com/tivisse/odoodays-2018/). This module for a plant nursery is training material developed for the OXP 2018. You don't need to code it on your side. But you can check the presentations in the {file}`/static/pdf` directory and play with the module to discover some magic features in Odoo.
