Hello Keegan, You may already have forgotten about your posting from last month - but I stumbled across the EXACT same error today, and figured out a way around it. The difficulty stems from you running under Windows XP, probably running InstantRails, right? I fairly quickly discovered that the reason things were not working according to the ActiveRBAC Manual was that the code for ActiveRBAC assumes that you are running under a LINUX system - or at least your file system follows the LINUX convention of /dir/some_other_dir/something_else/foo/bar... The offending code (at least so far for me) is a routine named realpath in the file InstantRails\ruby\lib\ruby\1.8\pathname.rb Since I am running InstantRails under Windows XP, I had to find a way around this issue to continue with exploring ActiveRBAC. I eventually got around this issue, but not by using the "rake db:migrate:engines" command. I have uploaded a batch file and 9 other supporting files in a ZIP file attached to this message. You need to: - download the ZIP file, - unzip the contents into the application directory for which you are trying to place the ActiveRBAC code - Open a Ruby console window - I open mine from the InstantRails application's "Manage Rails Applications..." dialog box - change into the unziped directory (_create_db) - run the command rbac_mysql_doit.bat This will populate a database named "rbac_test" with those tables needed for RBAC, plus the tables used in the "Articles" sample program listed within the ActiveRBAC Manual. This set of files is required because MySQL can not properly handle table creation and constraint creation at the same time. SO, I had to run eight different SQL command files in order to create all of the ActiveRBAC tables, then create the seven ActiveRBAC constraints. Also, this set of files creates a user "admin" with password "password" who has the role "Admin". This will at least allow you to continue along in the ActiveRBAC Manual's Articles example. Of course, for your own application, you will have to change the database table name listed in every rbac_mysql_X.sql file (where X=a, b, c, d, e, f, g, and h). Also, you will probably NOT need the database table "articles" created at the beginning of the rbac_mysql_a.sql file. Happy Programming!
