猫鼬Model.find不是函数吗?

花了数小时试图弄清楚这一点-我正在向我的应用程序添加一个新模型，但由于"TypeError:List.find不是一个函数"而失败.我还有另一个模型Items，它以相同的方式设置并且运行良好.路线似乎没有任何成功，但如果我将其连接到Item模型，它就会起作用.我是否错误地声明了架构?我需要用mongo或其他方式初始化模型吗?

Spent hours trying to figure this out - I'm adding a new Model to my app but it's failing with "TypeError: List.find is not a function". I have another model, Items, that is set up in the same way and is working fine. Things seem to be failing in the route but it works if I hook it up to the Item model. Am I declaring the Schema incorrectly? Do I need to init the model in mongo or something?

模型

var mongoose = require('mongoose'); var Schema = mongoose.Schema; var listSchema = new Schema({ name: { type: String, default: datestring + " List" } }); mongoose.exports = mongoose.model('List', listSchema);

路线

app.get('/lists', function (req, res, err) { List.find(function (err, docs){ //THIS IS WHAT'S FAILING res.json(docs); }); });

控制器

angular.module('pickUp').controller('ListsCtrl', ['$scope', '$http', 'ngDialog', 'lists', function($scope, $http, ngDialog, lists) { $scope.lists = lists.lists; }]);

工厂

angular.module('pickUp').factory('lists', ['$http', function($http){ var lists = { lists: [] }; lists.getAll = function(){ console.log("trying. . ."); $http.get('/lists').success(function(res){ angular.copy(res, lists.lists); }); }; return lists; }]);

config

$stateProvider .state('/', { url: '/', templateUrl: 'views/lists.html', controller: 'ListsCtrl', resolve: { listPromise: ['lists', function (lists){ return lists.getAll(); }]

推荐答案

您的模块导出不正确

var mongoose = require('mongoose'); var Schema = mongoose.Schema; var listSchema = new Schema({ name: { type: String, default: datestring + " List" } }); **mongoose.exports = mongoose.model('List', listSchema);** <!-- this is wrong -->

应该是

**module.exports = mongoose.model('List', listSchema)**
