Just tried to get up and running with Ruby on Rails as it looks very slick. Anyway first problem I had was apparently a common one but with various solutions. The error was
error Before updating scaffolding from new DB schema, try creating a table for your model (Product)
Anyway, the solution was to gem install mysql (choosing the latest) and then copying libmySQL.dll to windows/system32
So now I’m back on track :)
