Explanation of polymorphic in rails

Rails
1

Hi,
Does someone know rails polymorphic very well and can explain me how I
can
do something similar than polymorphic and change dynamically the table
name
for a polymorphic attribute.
I know already that normally you need a have a “_type” attribute to
define
the table name, but I would like to define my own way to retrieve to
table
name. I was trying with table_name=“xxx” but it doesn’t works

thanks

The foo_type column references a class name, not a table name. I am not
aware of any alternative mechanism for controlling by how polymorphic
associations are loaded (perhaps a concrete example might clarify
things)
