Again, the controller is returning a *relation*, rather than the actual
results. Try changing:
@people_skill = PeopleSkill.select('skill').where("{person_id => @person.id}")
to
@people_skill = PeopleSkill.select('skill').where("{person_id =>
@person.id}").all
Essentially this tells rails you are finished building the query and are
prepared for results - it will trigger a query against database.
I still can't help feeling you are experiencing these issues because you are
starting to swim upstream against the rails conventions. When things seem
difficult, there is usually some ruby voodoo missing. Knowing how to work
ruby and rails magic involves learning all the spells.
If you are still having difficulty, please post you model logic as well -
especially the relationships between the objects (belongs_to, has_many, etc)
