Not sure if that's what you're trying to achieve but
@awarenesses[0].positionawarenesses.select { |pa| pa.position_id == 12
}.first.level
might do the job.

Given that positionawarenesses has its own properties, you could also
pull this out into its own model. If nothing else, this would create a
very efficient query.
class PositionAwareness < ActiveRecord::Base
:belongs_to :awareness
:belongs_to :position
def self.find_by_position_id_and_awareness_id(position_id,
awareness_id)
find(
:all,
:conditions => [
"position_id = ? and awareness_id = ?",
position_id,
awareness_id
]
)
end
end
And in your controller:
PositionAwareness.find_by_position_id_and_awareness_id(12,
@awarenesses[0].id)
