Question

当我使用addSomething函数创建额外的关联时，Sequelize会更新标记关联的id字段为NULL的每个现有关联，然后使用关联的id再次重新更新它们中的每一个。为什么他们会这样做，更重要的是，我怎么能阻止它呢？

number.addCall(call).success(function(call){
  console.log("addCall");
});

和控制台输出：

addCall

它需要做的就是更新ONE记录，变量“call”代表的记录。一旦有数千个或更多的呼叫与一个号码相关联，这最终会破坏数据库。

原来这是1.6.0之前的版本中的一个问题，包括beta。更新到1.6.0使其表现符合预期。

Sequelize似乎正在更新添加的每个相关记录？
