Warum Rails 4 meine Sicht rendern, wenn ich redirect_to in einem response_to Block verwende

Question

Also innerhalb der response_to blockiert die bedingte if stockUpdated and stock != {} schlägt fehl und der else Block läuft (Ich habe dies mit byebug getestet). Also sollte der Server umleiten, aber stattdessen rendert es. Eine andere seltsame Sache ist, dass seit der Wiedergabe der flash.now[:alert] -'...' funktionieren sollte, aber das auch nicht in der Ansicht angezeigt wird (nimm mein Wort dafür).

Controller:

respond_to do |format| 
     if stockUpdated and stock != {} 
      format.js 
      format.html { 
       redirect_to user_path(@user), 
       notice: "#{stock.symbol} has been added to your portfolio!" 
      } 
     else 
      flash.now[:alert] = "We could not add that stock to your portfolio." 
      format.html{redirect_to user_path(@user)} 
     end 
    end 

Server:

Sie sollten and return nach der Umleitung hinzufügen:

respond_to do |format| 
    if stockUpdated and stock != {} 
    format.js 
    format.html { 
     redirect_to user_path(@user), notice: "#{stock.symbol} has been added to your portfolio!" 
    } 
    else 
    format.html{ 
     redirect_to user_path(@user), flash: {alert: "We could not add that stock to your portfolio."} and return 
    } 
    end 
end
