Meteor: Ausnahme in Rückruf von Asynchron-Funktion: onAfterAction

Question

Stilllegung Problem: Ich mag mit dem Brache-Code in einer Route eine Sammlung in dem onAfterAction Haken aktualisieren (Seiten = Name der Sammlung):

var document = pages.findOne({page: "stats"})._id; 
console.log(document); 
var counter = pages.findOne({_id: document}).counter + 1; 
console.log(counter); 
pages.update(document, { $set: { counter: counter },}); 

Und hier die ganze Route:

Router.route('/stats',{ 
     template: 'stats', 
     name: 'stats', 
     onBeforeAction: function(){ 
      //Ladeproblem muss noch gelöst werden 
      var currentUser = Meteor.userId(); 
      if(currentUser){ 
       this.next(); 
      } else { 
       Router.go('/'); 
      }  
     },onAfterAction: function(){ 
      var document = pages.findOne({page: "stats"})._id; 
      var counter = pages.findOne({_id: document}).counter + 1; 
pages.update(document, { $set: { counter: counter },}); 
     } 
    }); 

weiß jemand, was falsch ist oder was ich zu ändern, weil ich diesen Fehler bin:

Answer 1

Dies ist nur ein Verdacht, aber wenn Sie das Dokument ändern, das die aktuelle Route anzeigt, haben Sie möglicherweise eine Endlosschleife erstellt. Wenn Sie das Dokument ändern, wird die Route reaktiviert, und Sie erhöhen den Zähler und dann die Route wird erneut gerendert.

onAfterAction: function(){ 
    page.update({ page: "stats" },{ $inc: { counter: 1 }}) 
} 

:

Auch Ihre onAfterAction Haken ganz durch nur mit MongoDB der $inc (Erhöhung) Operator vereinfacht werden
