问题描述
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)**
