Scopes

Influxer metrics support scopes of two types: default and named (just like ActiveRecord).

class VisitsMetrics < Influxer::Metrics
  default_scope, -> { time(:hour) }
  scope :by_user, ->(id) { where(user: id) if id.present? } 
end

# default scope
VisitsMetrics.all #=> select * from visits group by time(1h)

# named scope
VisitsMetrics.by_user(1) #=> select * from visits group by time(1h) where user_id=1

# unscoped
VisitsMetrics.unscoped.by_user(1).time(:day) #=> select * from visits group by time(1d) where user_id=1
