View cause of rollback error in rails console

Question

I'm trying to update a record through the rails console and am getting a rollback error:

Project.find(118).update_attributes(:featured=>true)
  Project Load (2.6ms)  SELECT "projects".* FROM "projects" WHERE "projects"."id" = $1 LIMIT 1  [["id", 118]]
   (2.8ms)  BEGIN
   (1.3ms)  ROLLBACK
=> false

How can I view the source of the error? I'm able to update the attribute for other records, so I'd like to inspect why this particular record isn't working.

Your Project instance is probably invalid. To see what error prevented it from saving, you can type:

project = Project.find 118
project.assign_attributes(featured: true)
project.valid?
project.errors.full_messages
