流星模板助手物種不一致

Question

我有用於示出學校用反應性變種schoolFindQuery

Template.schoolCompareCenterList.helpers({ 
    schools(){ 
    console.log("schoolFindQuery is :" + schoolFindQuery); 
     let school = Schools.find(JSON.parse(schoolFindQuery), {limit : 20}); 
     console.log("school count is : " + school.count()); 

     return school; 
} 
}) 

和schoolFindQuery反應變量與按鈕點擊改變模板幫手，用按鈕點擊訂閱新資料被更新，用戶界面是相應地改變。奇怪的是，當訂閱返回數據沒有問題時，但是每當訂閱返回任何數據時，在此之後，助手代碼將不會重新運行訂閱更改（即使我可以看到流星玩具的訂閱），並且ui不顯示任何數據。 我的訂閱代碼如下，提前

this.autorun(function() { 


if(subscription) 
    subscription.stop() 


//This reactive variables set by buttons and by the ghelp of reactivty subscription rerun 
    query = "{" 
    if(_sTy__.get() != 0 && _sTy__ != null) 
     query += "\"schoolType.schoolT\" : \"" + _sTy__.get()+ "\"," 
    if (_sTy2__.get() != 0 && _sTy2__ != null) 
     query += "\"schoolType.schoolTT\" : \""+ _sTy2__.get() +"\"," 
    if(regexSchoolName.get() != 0 && regexSchoolName.get() != null) 
     query += "\"schoolName\" : {\"$regex\": \".*" + regexSchoolName.get() + ".*\", \"$options\": \"i\"}," 

    query += "\"haveSchoolDetailInfo\" : true}" 

    subscription = Meteor.subscribe("schoolCompare.infinite.publish", query, 20, 0); 
    schoolFindQuery = query;}) 

感謝。

，我建議你看看這個教程這也解釋了Session變量，無快譯通和無功：https://blog.meteor.com/the-meteor-chef-reactive-dict-reactive-vars-and-session-variables-971584515a27#.undr5c1f0
