Hi, I was wondering if anyone else was having the same problem as me. I''ve recently started moving some appplications to start using migrations for the schema updates. The problem I''m having is when I have a blob field in the schema, it gets defined as so: t.column "permission_file", :binary When I run rake migrate I get the following error: rake aborted! undefined method `string_to_binary'' for ActiveRecord::ConnectionAdapters::ColumnDefinition:Class Removing this in the migration script stops the error occurring. The database is MySql 4.1 and I''m running the latest release of Rails from gems on OS X 10.4. What am I doing wrong? Any help would be greatly appreciated. Cheers Jonathan
