Ember：对store.query的响应预计是一个数组，但它是一个logging错误

我不断收到错误：

错误：断言失败：对store.query的响应预期是一个数组，但是它是单个logging。 请将您的响应封装在数组中，或使用store.queryRecord查询单个logging。

这是我的后端：

 router.route('/') .post(parseUrlencoded, parseJSON, function (request, response) { var advancedStanding = new models.AdvancedStandings(request.body.advancedStanding); advancedStanding.save(function (error) { if (error) response.send(error); response.json({advancedStanding: advancedStanding}); }); }) .get(parseUrlencoded, parseJSON, function (request, response) { //var l = parseInt(request.query.limit); //var o = parseInt(request.query.offset); var AdvancedStanding = request.query.filter; if (!AdvancedStanding) { models.AdvancedStandings.find(function (error, advancedStandings) { if (error) response.send(error); response.json({advancedStanding: advancedStandings}); }); //models.AdvancedStandings.paginate({}, { offset: o, limit: l }, // function (error, students) { // if (error) response.send(error); // response.json({advancedStanding: advancedStandings.docs}); // }); } else { // if (Student == "residency") models.AdvancedStandings.find({"studentInfo": AdvancedStanding.studentInfo}, function (error, advancedStandings) { if (error) response.send(error); console.log(advancedStandings); response.json({advancedStudent: advancedStandings}); }); } }); 

这是我的前端：

 showStudentData: function (index) { this.set('currentStudent', this.get('studentsRecords').objectAt(index)); this.set('studentPhoto', this.get('currentStudent').get('photo')); var date = this.get('currentStudent').get('DOB'); var datestring = date.toISOString().substring(0, 10); this.set('selectedDate', datestring); var self2 = this; this.get('store').query('advanced-standing',{filter:{studentInfo:'585df32e0bf2ba5ea6951592'}}) .then(function(records123){ console.log(records123); }); 

}

有什么想法，这是怎么回事？

谢谢。

Answer 1

query函数需要多个结果。 所以你需要使用queryRecord

 this.get('store').queryRecord('advanced-standing',{filter:{studentInfo:'585df32e0bf2ba5ea6951592'}}) .then(function(records123){ console.log(records123); }); 

或者将你的响应包装在数组中

 if (!AdvancedStanding) { models.AdvancedStandings.find(function (error, advancedStandings) { if (error) response.send(error); response.json([{advancedStanding: advancedStandings}]); // you were returning a single object // note the array is now wrapping your previous result }); //models.AdvancedStandings.paginate({}, { offset: o, limit: l }, // function (error, students) { // if (error) response.send(error); // response.json([{advancedStanding: advancedStandings.docs}]); // you were returning a single object // note the array is now wrapping your previous result // }); } else { // if (Student == "residency") models.AdvancedStandings.find({"studentInfo": AdvancedStanding.studentInfo}, function (error, advancedStandings) { if (error) response.send(error); console.log(advancedStandings); response.json([{advancedStudent: advancedStandings}]); // you were returning a single object // note the array is now wrapping your previous result }); }
