DataMapper.auto_upgrade! Question
Raw
gistfile1.rb
# Departamento Version 1.0
class Departamento
include DataMapper::Resource
property :id, Serial
property :nombre, String, :index => true
end
# Then I run rackup with DataMapper.auto_upgrade!, which creates the tables with the structure above.
# What if I change something in the structure, eg.
# Departamento Version 1.0
class Departamento
include DataMapper::Resource
property :id, Serial
property :nombre, String, :index => true, :required => true
end
# Then I run rackup again. Will DataMapper.auto_upgrade!, run the proper SQL statements to change the column?

Great, this makes sense. It just wasn't clear enough in the getting started page.

I like your idea about inspecting the data and then allowing or not an auto_upgrade!

Thanks!
