我有一个称为服务的模型
/**

module.exports = {

studioId:{
model:"Studios"
},
bookedServices:{
collection: 'BookedServices',
via: 'serviceId'
},
timings:{
collection: 'Timings',
via: 'serviceId'
}
},
};
这是我添加服务的操作文件。
由于某种原因，等待Services.create无法正常工作，并且由于未定义serviceRecord，因此返回此badRequest错误。但是当我转而使用此处是exec的promises时，我看到正在创建记录，但是作为exec中第二个参数的结果也未定义。
由于我不得不将studioId推入服务，因此我别无选择，只能在制作记录时将其包括在内，尽管这也显示badRequest，但它会将记录放入数据库中。
如果有人能告诉我问题的原因，将不胜感激。我检查了要放入Service模型中的参数类型，它们确实匹配，serviceName是字符串，creditCost和price是数字。

这是另一个称为Timings的api，甚至有同样的问题。在创建新文档的过程中我做错了什么吗？

在控制器中，错误和结果的控制台日志语句由于某种原因未定义返回。
该如何解决？任何帮助将不胜感激。

如documentation for Waterline's create method中所述，如果要复制新创建的记录，则需要链接.fetch()方法或.meta({ fetch: true })
应该执行以下操作：
let serviceRecord = await Services.create({
nameService: newNameService,
creditCost,
price
}).fetch();
sails.log.info(serviceRecord);

在新版本的Sails中，您需要添加.fetch()才能在使用.create()时发回记录
来自docs的示例：
var newUser = await User.create({ fullName: 'Alice McBailey' }).fetch();
