我正在使用angularjs,结合mongolab,来创建一个基本的应用程序。
问题是,我试图更新日期(当我点击“editer”时),但是当我提交表单时,得到了错误:
TypeError: Object #<Resource> has no method 'update'
更新方法是定义的,所以我不理解错误,任何帮助?
答案 0 :(得分:2)
您可以稍微更改项目工厂:
评论后更新
angular.module('mongolab', ['ngResource']).
factory('Project', function($resource) {
var ProjectApi = $resource('https://api.mongolab.com/api/1/databases' +
'/villes/collections/universities/:id',
{apiKey: '7pcSaEmpVzZ90V6CVggeHa6Ys71uaZOA'}, {
update: {method: 'PUT'}
}
);
var Project = function(data) {
angular.extend(this, data);
};
Project.query = ProjectApi.query;
Project.get = ProjectApi.get;
Project.prototype.update = function(cb) {
return ProjectApi.update({id: this._id.$oid},
angular.extend(this, {_id: undefined}), cb);
};
Project.prototype.destroy = function(cb) {
return ProjectApi.remove({id: this._id.$oid}, cb);
};
return Project;
});
在EditCtrl
你做了一件奇怪的事情:
function EditCtrl($scope, $location, $routeParams, Project) {
var self = this;
// Project is already defined in arguments and it is a service
var Project = Project.instance();
}
调用Project.instance()
将返回没有任何update()方法的普通资源对象!查看Project factory中的代码。
同时更改EditCtrl中的代码:
function EditCtrl($scope, $location, $routeParams, Project) {
var self = this;
Project.get({id: $routeParams.projetId}, function(projet) {
self.original = projet;
$scope.projet = new Project(self.original);
});
$scope.save = function() {
$scope.projet.update(function() {
$location.path('/list');
});
};
}
最后你会让它发挥作用。
