Ruby on Rails: reuse code across other multiple actions -


i have multiple actions within single controller , want reuse of codes in 1 of actions. decided put in model class method. unfortunately, returned variables can not accessed in view. here can see controller action (model method calling check_bibip_prices)

def sold_to_winner   @soldcars = soldcar.winner_username(params[:winnerusername]).order("auctioncarenddate desc").paginate(:page => params[:page], :per_page => 15)   @page_name = "cars sold to: " + params[:winnerusername]    render :index   authorize! :show, @soldcars    @car_buy_prices, @car_sell_prices, @car_status, @car_salesprice_background, @car_winnersalesprice_background = soldcar.check_bibip_prices(@soldcars) end

model can seen follows:

class soldcar < applicationrecord   belongs_to :bibipprice    scope :isongoingauction, ->(isongoingauction) { isongoingauction: isongoingauction }   scope :winner_username, ->(winnerusername) { where(winnerusername: winnerusername) }    def self.check_bibip_prices(soldcars)     @car_buy_prices = {}     @car_sell_prices = {}     @car_status = {}     @car_salesprice_background = {}     @car_winnersalesprice_background = {}      @soldcars.each |car|       if (car.paintbodydamage < 10) , (car.mechanicaldamage < 2)         @car_status[car.carid] = "excellent"         @car_buy_prices[car.carid] = car.bibipprice.dealer_price_three         @car_sell_prices[car.carid] = car.bibipprice.estimated_price_three       elsif (car.paintbodydamage < 18) , (car.mechanicaldamage < 5)         @car_status[car.carid] = "good"         @car_buy_prices[car.carid] = car.bibipprice.dealer_price_two         @car_sell_prices[car.carid] = car.bibipprice.estimated_price_two       else         @car_status[car.carid] = "fair"         @car_buy_prices[car.carid] = car.bibipprice.dealer_price_one         @car_sell_prices[car.carid] = car.bibipprice.estimated_price_one        end        if car.bibipprice.estimated_price_three > 0          if car.winnersalesprice > @car_sell_prices[car.carid]           @car_winnersalesprice_background[car.carid] = "pricealert"         elsif car.winnersalesprice > @car_buy_prices[car.carid]           @car_winnersalesprice_background[car.carid] = "pricesoso"         elsif car.winnersalesprice > 0           @car_winnersalesprice_background[car.carid] = "priceok"         end          if car.salesprice > @car_sell_prices[car.carid]           @car_salesprice_background[car.carid] = "pricealert"         elsif car.salesprice > @car_buy_prices[car.carid]           @car_salesprice_background[car.carid] = "pricesoso"         else           @car_salesprice_background[car.carid] = "priceok"         end       else         @car_salesprice_background[car.carid] = ""         @car_winnersalesprice_background[car.carid] = ""       end     end      return @soldcarscar_buy_prices, @soldcarscar_sell_prices, @soldcarscar_status, @soldcarscar_salesprice_background, @soldcarscar_winnersalesprice_background    end end

the problem instantiate variables after calling render method.

put render :index @ bottom of sold_to_winner method , should work:

def sold_to_winner   @soldcars = soldcar.winner_username(params[:winnerusername]).order("auctioncarenddate desc").paginate(:page => params[:page], :per_page => 15)   @page_name = "cars sold to: " + params[:winnerusername]   authorize! :show, @soldcars   @car_buy_prices, @car_sell_prices, @car_status, @car_salesprice_background, @car_winnersalesprice_background = soldcar.check_bibip_prices(@soldcars)   render :index end

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
