ng-repeat不从数据库绑定

我有一个1页的应用程序,它应该显示数据库中的对象列表。我使用ng-repeat创建一个模板来绑定db中数组的数据。因为我是Angular的新手所以任何帮助都会很棒。我的代码如下:

SERVER.JS

var express = require('express');
var app = express();
var mongojs = require('mongojs');
var db = mongojs('eventlist', ['eventlist']);
var bodyParser = require('body-parser');


app.use(express.static(__dirname + "/public"));
app.use(bodyParser.json());

app.get('/eventlist', function (req, res) {
  console.log("i received a get request")

  db.eventlist.find(function(err, docs){
    console.log(docs);
    res.json(docs);
  });
});


app.post('/eventlist', function (req, res){
  console.log(req.body);
  db.eventlist.insert(req.body, function (err, doc) {
    res.json(doc);
  });
});

app.delete('/eventlist/:id', function(req, res){
  var id = req.params.id;
  console.log(id);
  db.eventlist.remove({_id: mongojs.ObjectID(id)}, function (err, doc) {
    res.json(doc);
  });
});

app.get('/eventlist/:id', function (req, res) {
  var id = req.params.id;
  console.log(id);
  db.eventlist.findOne({_id: mongojs.ObjectId(id)}, function (err, doc) {
    res.json(doc);
  });
});

app.put('/eventlist/:id', function (req, res) {
  var id = req.params.id;
  console.log(req.body.name);
  db.eventlist.findAndModify({
    query: {_id: mongojs.ObjectId(id)},
    update: {$set: {name: req.body.name, startDate: req.body.startDate, price: req.body.price, location: req.body.location}},
    new: true}, function (err, doc) {
      res.json(doc);
    }
  );
});


app.listen(4000);
console.log("Server running on port 4000");

将其更改为 response.data

var refresh = function(){
  $http.get('/eventlist/').then(function(response) {   
    $scope.eventlist = response.data;
    $scope.event = null;
  });
};
