In Rails console: I was wondering if you could list/examine what databases/objects are available to you. Yes I know you can see using other tools, just curious if you can inspect them inside the Rails console. thanks.

Its a start, it can list:
models = Dir.new("#{RAILS_ROOT}/app/models").entries
Looking some more...

You are probably seeking:
ActiveRecord::Base.connection.tables
and
ActiveRecord::Base.connection.table_structure("projects")
You should probably wrap them in shorter syntax inside your .irbrc.

Thanks, the first one works like I want. But the second one doesn't - hunted for something similar but no luck.

ActiveRecord::Base.connection.columns("foos") should also work, but it returns column objects, .map{|c| [c.name, c.type] } on the end fixes that.
