Hello,

anybody have any clue why the following is happening: if i do “rake  
db:drop, rake db:create, rake db:migrate” everything is fine but if i  
do “rake RAILS\_ENV=testing db:drop”, then “rake RAILS\_ENV=testing  
db:create” & then “rake RAILS\_ENV=testing db:migrate” it fails on the  
migrate part, i get “Validation Failed: Group has already been taken”  
in the middle of the migration
