angularjs - Angular directive for validation using two models -

-

After the "text" itemprop = "text">

using the new $ authenticator objection on ngModel, I in addition to an input data area in the input field in addition Validate the directivity works great in a checkbox if the checkbox (un) is checked before the user input, but if the user is input and then clicks on the checkbox, there is no verification Is not.

Is there a way to trigger the verification box, either the checkbox or input field changes?

The code looks like this: 

  app.directive ('denyMultiples', function () {return required: 'ngModel', scope: {denyMultipleCheck: '='}, Link: function (scope, element, attrs, ngModel) {ngModel $ validators.multiples = function (value). {{Value = value.split (',') (Array.isArray (value)! );} Return value.length & lt; 2 || scope.denyMultipleCheck;};}};}); // HTML & lt; Input name = "item" deny-multiples deny-multiples-check = "query.deny_multiples_check" ng-model = "item" & gt;    
 
 
 I use to determine whether it was able to meet ng required , Then the verifier should not be run or not  
  & lt; Input name = "item" denial-multiples denial-multiples-check = "query.deny_multiples_check" ng-required = "query.deny_multiples_check" ng model = "item" & gt; If the checkbox is checked, the $ validation will be run. Otherwise the check is ignored.

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
