流星：異常在異步函數的回調：onAfterAction

休耕問題：我想在休耕代碼的路線來更新onAfterAction鉤集合（頁=收集的名稱）：流星：異常在異步函數的回調：onAfterAction

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 },});

這裏整個路線：

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 },}); 
     } 
    });

有誰知道什麼是錯的或者我已經改變，因爲我得到這個錯誤是什麼：

這只是一個懷疑，但如果您正在更改當前路線顯示的文檔，您可能已經創建了一個無限循環 - 更改文檔會導致路線被反應重新渲染，然後增加計數器，然後增加路線再次呈現，重複。

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

：

而且你onAfterAction鉤可以通過只使用MongoDB的$inc（增量）操作來簡化相當
