流星允许Upsert?

标签: collections meteor upsert

尝试插入集合时在控制台中出现此错误:

“更新失败:访问被拒绝。限制集合中不允许进行Upsert。”

以下是我指定的允许规则:

if (Meteor.isClient) {
    Meteor.subscribe('customers');
}

customers = Customers

if (Meteor.isServer) {

Meteor.publish('customers', function() {
    return customers.find();
});

customers.allow({

    insert: function (document) {
        return true;
    },
    update: function () {
        return true;
    },
    remove: function () {
        return true;
    }

    });

}

这是upsert部分:

Customer.prototype.create = function ( name, address, phone, cell, email, website, contact, shipping ) {

var attr = {
    name : name, 
    address : address, 
    phone : phone,
    cell : cell,
    email : email,
    website : website,
    contact : contact,
    shipping : shipping
};

Customers.upsert( Customers.maybeFindOne( attr )._id, attr );

    return new Customer( attr );
};

这是a choice the development team

建议的解决方案是编写一个包装upsert的方法。这使得服务器请求来自服务器代码,而客户端代码仅运行延迟补偿。例如:

//shared code
Meteor.methods({
  customersUpsert: function( id, doc ){
     Customers.upsert( id, doc );
  }
});

//called from client
Meteor.call( 'customersUpsert', Customers.maybeFindOne( attr )._id, attr );

这是我使用的解决方法(使用下划线默认功能):

_upsert: function(selector, document) {
  if (this.collection.findOne(selector) != null) {
    this.collection.update(selector, {
      $set: document
    });
  } else {
    this.collection.insert(_.defaults({
      _id: selector
    }, document));
  }
}

假设selector是对象ID。
