Hello All, I followed steps to install Rspec as in the link pasted below. http://www.pmamediagroup.com/2009/04/tutorial-install-rspec-rails-factory-girl/ I have jRuby on Rails installed on my machine.Hence all commands need to be run with jruby -S extension. However when I run the jruby -S rake spec command,I get the following error as shown below. ************************************************************************************************************************ C:\Rspec Test>jruby -S rake spec --trace (in C:/Rspec Test) ** Invoke spec (first_time) ** Invoke db:test:prepare (first_time) ** Invoke db:abort_if_pending_migrations (first_time) ** Invoke environment (first_time) ** Execute environment db pool warmup starting......................

commenting all lines having drop_database statement in them. Another thing is that the database already has tables and by using the tutorial I have just added another table for the bank-account. Kindly let me know what exactly needs to be done in this case Thanks & Regards Chandrika -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
