Class Method Details

.sql_type_for(field) ⇒ Object

When detecting types, ActiveRecord expects strings in a certain format. In 4.2, these strings are converted to ActiveRecord::Type::Value objects using the type_map (see #initialize_type_map). Prior to 4.2, the sql_type could be coerced to a certain ActiveRecord type in Column#simplified_type.
