无法使用nodejs在mongodb中插入或创建

Question

为什么我无法使用nodejs在mongodb中创建。 我可以使用mongo shell插入数据。 但是如果我使用带有mongoose的nodejs插入数据。有一个错误。

    { MongoError: not authorized on node-angular to execute command { insert: "users", documents: [ { firstName: "Angelo", lastName: "Castillo", password: "password", email: "asdad@gmail.com", _id: ObjectId('59d
70936284aad66d4d1207b'), messages: [], __v: 0 } ], ordered: false }

  code: 13,
  codeName: 'Unauthorized' }

这是我在node-angular db中的用户。

> show users
{
        "_id" : "node-angular.nodeangular",
        "user" : "nodeangular",
        "db" : "node-angular",
        "roles" : [
                {
                        "role" : "dbOwner",
                        "db" : "node-angular"
                },
                {
                        "role" : "readWrite",
                        "db" : "node-angular"
                }
        ]
}
