Hi,

Friend when you create any "new" object usign UserSkill or any class
class
which is associated with ActiveRecords.. then it auto create one hash
with all attributes of user_skills(or any relevant) table.. this is due
to ORM feature of the Rails..

Second thing, that all values seems to nil in that hash.. this is
because it provide you blank hash.. to do process or to assign required
values to
the attributes..

nil is just because as we know ruby has greate feature of NilClass to
avoid exceptions on nil values..

I dont know is this answer of your question or not.

Good luck ;)
