ruby on rails - Scope conditionals for count? -

-

how can scope work multiple .count?

scope :level_5, -> { (self.accomplished.key.count > 4) && (self.accomplished.adventure.count > 2) && (self.accomplished.health.count > 2) && (self.accomplished.work.count > 2) }

i've tried:

scope :level_5, -> { self.accomplished.key.count > 4, self.accomplished.adventure.count > 2, self.accomplished.health.count > 2), (self.accomplished.work.count > 2) }

or

scope :level_5, -> { accomplished.where(key.count > 4, adventure.count > 2, health.count > 2, work.count > 2) }

or

scope :level_5, -> { "user.accomplished.key.count > 4" && "user.accomplished.adventure.count > 2" && "user.accomplished.health.count > 2" && "user.accomplished.work.count > 2" }

it used conditionals if :level_5 trigger x.
