环回:将model.settings.validateUpsert覆盖为false [英] Loopback: model.settings.validateUpsert was overriden to false
问题描述
我有一个使用MongoDB的回送应用程序，如下所示，但是我的问题是关于终端上的消息(不是错误)，所以我的终端看起来像这样:
I have a loopback app with MongoDB as below, however my question is about a message on my terminal (not an error) so my terminal would look like this:
dishes settings.validateUpsert was overriden to false
Comments settings.validateUpsert was overriden to false
Web server listening at: http://localhost:3000
Browse your REST API at http://localhost:3000/explorer
我的应用程序文件夹的路径....>节点.
The path to my app folder....> node .
如您所见，服务器运行时没有错误.该消息是什么意思?我设法通过将TimeStamp设置为false来避免这种情况:
As you can see that the server runs without an error. What is the meaning of that message? I managed to avoid it by setting TimeStamp to false like this:
"mixins": {
"TimeStamp": true // => change this to false.
}
但是我不相信这种解决方案.
but I'm not convinced with this solution.
这是我的模特:

和script.js:
and script.js:
module.exports = function(app) {
var MongoDB = app.dataSources.MongoDB;
MongoDB.automigrate('Customer', function(err) {
if (err) throw (err);
var Customer = app.models.Customer;
Customer.create([
{username: 'Admin', email: 'admin@admin.com', password: 'abcdef'},
{username: 'muppala', email: 'muppala@ust.hk', password: 'abcdef'}
], function(err, users) {
if (err) throw (err);
var Role = app.models.Role;
var RoleMapping = app.models.RoleMapping;
Role.find({ name: 'admin' }, function(err, results) {
if (err) { throw err; }
if (results.length < 1) {
// now we know the DB doesn't have it already, so do the Role creation...
//create the admin role
Role.create({
name: 'admin'
}, function(err, role) {
if (err) throw (err);
//make admin
role.principals.create({
principalType: RoleMapping.USER,
principalId: users[0].id
}, function(err, principal) {
if (err) throw (err);
});
});
}
});
});
});
};
推荐答案
这是loopback-ds-timestamp-mixin的要求.
请参见 https://github.com/clarkbw/loopback-ds-timestamp-mixin/blob/master/es6/time-stamp.js#L25 .
如果validateUpsert是true，则混合显示警告:
If validateUpsert were true, the mixin shows a warn:
当打开验证并需要时间戳时，ModelName的Upserts将失败"
"Upserts for ModelName will fail when validation is turned on and time stamps are required"
更新
要隐藏此警告，请按以下方式设置TimeStamp混合:
UPDATE
To hide this warns, set the TimeStamp mixin like this:
...
"mixins": {
"TimeStamp": {
"required" : false,
"validateUpsert": true,
"silenceWarnings": false
}
},
...
