In this tutorial, you will be creating your custom settings in Odoo and I will be showing you how to do this. This will lay a foundation for you when planning on developing your own module.
While creating your custom settings in Odoo, there are some things you need to do to achieve this.
I have created a video for you to explain in details, how you should achieve this.
I hope you learnt a lot from this. You can also check out How to Add Chatter to a Model in Odoo.
Feel free to share and comment. I promise to share the second part, which I will be talking about using fields and making sure inputted data are saved.
