Compare with:

inheritance_column()

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'
