I'm following this tutorial: http://friendlyorm.com/
I'm using InstantRails to run MySQL locally. To run Ruby and Rails, I'm using normal Windows installations.
When I run Friendly.create_tables! I only get an empty Array returned: => [] and no tables are created in my 'friendly_development' database.
Author of Friendly here.
You'll have to require all of your models before calling Friendly.create_tables! Otherwise, there's no way for Friendly to know which models exist. In a future revision, I'll automatically preload all your models.
