Rails: Better understanding dynamic scopes -


this "dynamic" scope:

  def all_games(conditions = {})     scope = games.includes(:stats).scoped {}     scope = scope.where sport_position_id: conditions[:sport_position_id] unless conditions[:sport_position_id].nil?     scope = scope.where sport_id: conditions[:sport_id] unless conditions[:sport_id].nil?     scope = scope.where team: conditions[:team]     scope.order(:date)   end

the method above in module included user model.

so access in code, so:

u = user.find(1) u.all_games(sport_position_id: params[:sport_position_id], sport_id: current_sport.id, team: params[:team])

when doing google searching dynamic scopes, came across ryan bate's railscast on anonymous scopes (http://railscasts.com/episodes/112-anonymous-scopes). modified since using rails 3, wondering, if on right path when comes writing dynamic scopes?

i find myself writing dynamic scopes because of nature of complex api's writing.
