I'm sorry if this is a stupid question, but in my schema.rb I have several tables like
create_table "messages", :force => true do |t|
t.integer "user_id", :null => false
t.string "message", :null => false
t.datetime "created_at", :null => false
A database schema represents the structure of the database, not the content of it.
If you want to access the content in your database, you would query it to do so. You can do that via command line clients (running
$ rails dbconsole will try to open one for the configured database) or graphical tools like Sequel Pro (for MySQL on Mac OS X).
You can also get this through your Rails application by running
$ rails console and then using the methods available through ActiveRecord (e.g.
User.where(:name => 'Billy').limit(5)).
