php - Laravel populating the current class from its ID -

-

I am looking at creating a solution using the famous in Larval 4 such as 

  $ message_id = 123; $ Message = new message (); If (! $ Message-> loadFromId ($ message_id)) {message 'Failed to get message'; } And {return $ message-> Get ('body'); }   
 However I can not decide how to do this. I know that Larval Gas gives an example of return class to a 'search' method but it is not what I need. I want to be able to load the current class and want to return a boolean. I think there is a load method in Larval, for which relationship is required.  
 I think I can make a new method like 'LoadFrame ID', with a series of best ways I wanted. but I'm not sure. I think I will drag a 'relation' (whatever) from the database and will use it with the load method.  
 Can anyone help me with this?   
 
 
 This is the method for finding what you want:  
  $ Message_id = 123; $ Message = message: search ($ message_id); If (! $ Message) {return 'failed to receive message'; } And {return $ message-> Body; }

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
