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)
