ruby - Rails before_filter different arguments -

-

i have controller actions use 1 method different arguments. can refactor somehow use before_filter?

  def usd_cash     transaction_currency("usd cash")   end    def usd_bank     transaction_currency("usd bank")   end    def rub_bank     transaction_currency("rub bank")   end    private    def transaction_currency(currency)     @transactions = transaction.where(location: "#{currency}")   end

you use metaprogramming, not readable have:

%i(   usd_cash   usd_bank   rub_bank ).each |method|   define_method method     transaction_currency(method.to_s.split('_').instance_eval {first.upcase + ' ' + last})   end end
