ruby on rails - How to replace object with coffee script? -

-

I am creating a user notification system and there is a problem, I do not know how to refresh my @activities on my header layout I'm:

application_controller.rb 

  before_filter: activity def track_activity (user, trackable, action = param [: action], author = current_user) activity . Create! Users: User, Trackable: Trackable, Action: Action, Author: Author PrivatePub.publish_to ("/ Message / New", Good: Activity) End DIF Activity if signed_in? @activities = current_user.activities.includes (: author,: trackable) .order (created_at :: desc) end-of-end   
 layout / _header.html.erb  
  & lt; Div class = "user-notification" & gt; & Lt; One class = "FA-FA-life-ring FA-LG" href = "javascript: zero (0);" tabindex = "1" & gt; & Lt; / A & gt; & Lt; div class = "activity activity_open" id = "activity" & gt; & Lt;% @ activities.each do | Activity | & Gt%; & Lt;% = link_to activity.user.name, activity.user% & gt; & Lt;% = render "activities / # {activity.trackable_type.underscore} / # {activity.action}", activity: activity% & gt; & Lt;% end% & gt; & lt;% = subscribe_to "/ message / new"%> & Lt; / Div & gt; & Lt; / Div & gt;   
 javascripts / messages.js.coffee  
  Privatepubs subscriptions "/ messages / new", (data, channel) - & gt; Warning $ ("#Activity") Attachments ("& lt;% = data.cool = @ activities%>");   
 But the alert shows  [object object]   
 How can I update @activities? help please!   
 
 
 You can not access the example variable in the coffeespace script. If you have to do something partially updated, you can put the eddie code in the view directory corresponding to the action in the file and it can give the same name as the action.  
 So if the name of the controller is Fu and the action is named bar, you need a file called 'bar.jes' inside 'Controllers / Foo /' in which it has append code. If you need, you can call the coffee script function from that file, but you can not access the frequency variable directly from the coffeizet file.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
