application, and save it to a User database table. However, when I try to
save the user (i.e. add a line to the User table) the Ruby console just
returns false, with no explanation. Using *create *instead of *save *does
the same. I have tried deleting the database and doing the migration again,
but got the same result. How can I obtain more diagnostic on why the save
to database is failing?
Here a transcript from the console:
Loading development environment (Rails 3.2.9)
irb(main):001:0> user= User.new screen_name: "ginopino", real_name: "Gino
Pilotino", password: "foobar", password_confirmation: "foobar"
=> #<User id: nil, screen_name: "ginopino", real_name: "Gino Pilotino",
created_at: nil, updated_at: nil, password_digest:

←[1m←[35m (0.0ms)←[0m rollback transaction
