我收到此错误,我发现许多帖子都有相同的消息,但它似乎永远不符合我的情况,而且我没有经理解决它。
基本上,一切都没问题,直到我尝试制作1张表格来创建和更新“汽车”。对象
以下是我的应用程序的演示文稿(从此模板构建:https://github.com/linnovate/mean):
/public/js/config.js:
[...]
.state('edit car', {
url: '/cars/:carId/edit',
templateUrl: 'views/cars/edit.html'
})
.state('create car', {
url: '/cars/create',
templateUrl: 'views/cars/edit.html'
})
/public/js/services/mycars.js(真的不知道用于...的服务):
//Cars service used for car REST endpoint
angular.module('mean.mycars').factory('Cars', ['$resource', function($resource) {
return $resource('cars/:carId', {
carId: '@_id'
}, {
update: {
method: 'PUT'
}
});
}]);
公共/ JS /控制器/ mycars.js:
angular.module('mean.mycars').controller('MyCarsController', ['$scope', '$http', '$stateParams', '$location', 'Global', 'Cars',
function ($scope, $http, $stateParams, $location, Global, Cars) {
$scope.findOneOrCreate = function () {
// create a new car
var car = new Cars({
id : null,
marque: this.marque,
modele: this.modele,
desc: this.desc
});
// put new car in scope
$scope.car = car;
// if there is a param, search for the car (mode update)
if ($stateParams.carId !== null){
Cars.get({
carId: $stateParams.carId
}, function(carTmp) {
// put the result in scope
$scope.car = carTmp;
});
}
};
$scope.createOrUpdate = function () {
var car = $scope.car;
if (car.id !== null) {
// update
if (!car.updated) {
car.updated = [];
}
car.updated.push(new Date().getTime());
car.$update(function () {
$location.path('cars/' + car._id);
});
}
else {
//Create
car.$save(function (response) {
$location.path('cars/' + response._id);
});
}
};
最后我的观点是:edit.html:
<section data-ng-controller="MyCarsController" data-ng-init="findOneOrCreate()">
<form class="form-horizontal col-md-6" role="form" data-ng-submit="createOrUpdate()">
<div class="form-group">
<label for="title" class="col-md-2 control-label">Title</label>
<div class="col-md-10">
<input type="text" class="form-control" data-ng-model="car.modele" id="title" placeholder="Title" required>
</div>
</div>
<div class="form-group">
<label for="content" class="col-md-2 control-label">Content</label>
<div class="col-md-10">
<textarea data-ng-model="car.marque" id="content" cols="30" rows="10" placeholder="Content" class="form-control" required></textarea>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</div>
</form>
</section>
编辑以添加信息: Web服务应该只返回一辆汽车(但不确定是否这样),这里是:
exports.car = function(req, res, next, id) {
Car.load(id, function(err, car) {
if (err) return next(err);
if (!car) return next(new Error('Failed to load car ' + id));
req.car = car;
next();
});
};
exports.create = function(req, res) {
var car = new Car(req.body);
car.user = req.user;
car.save(function(err) {
if (err) {
return res.send('users/signup', {
errors: err.errors,
car: car
});
} else {
res.jsonp(car);
}
});
};
exports.update = function(req, res) {
var car = req.car;
car = _.extend(car, req.body);
car.save(function(err) {
if (err) {
return res.send('users/signup', {
errors: err.errors,
car: car
});
} else {
res.jsonp(car);
}
});
};
当我转到/ cars / create时出现错误消息,而不是当我转到/ cars /:carsId / edit:
Error: [$resource:badcfg] Error in resource configuration. Expected response to contain an object but got an array
http://errors.angularjs.org/1.2.15/$resource/badcfg?p0=object&p1=array
答案 0 :(得分:29)
您的网络服务是否返回了数组? get方法只需要返回一个对象,如果你要返回一些东西,则与PUT请求相同。如果您期望多次,则需要在mycars.js中的服务方法中指定isArray: true
。请参阅此处的示例:http://docs.angularjs.org/api/ngResource/service/$resource
