inheritance_column()
Instance Public methods
Defines the name of the table column which will store the class name on
single-table inheritance situations.
The default inheritance column name is type, which means
it's a reserved word inside Active Record. To be able to use single-table
inheritance with another column name, or to use the column
type in your own model for something else, you can set
inheritance_column:
self.inheritance_column = 'zoink'
