Hello Dep,


_inherits means you can access all the fields from existing class but in database, there is create a new table for it.

For Ex:-

In your custom class hotel_room_amenities_type, you can access all the fields from the product.category but in database there is create new table for your class.

In your custom class, you may give the many2one fields for existing models is compulsory.


_inherit means you extend the existing model.


Thanks,

Thanks.....
