alias __type_to_sql_enum type_to_sql

#type_to_sql(type, limit = nil, precision = nil, scale = nil) ⇒ Object

Add enumeration support for schema statement creation. This will have to be adapted for every adapter if the type requires anything by a list of allowed values. The overrides the standard type_to_sql method and chains back to the default. This could be done on a per adapter basis, but is generalized here.

will generate enum(‘a’, ‘b’, ‘c’) for :limit => [:a, :b, :c]
