Neo4j 日期时间验证错误

Question

I'm trying to update a field with datetime datatype for Neo4j instance running locally. I'm using neode with NodeJs v12.5.0 and Neo4j Version: 3.5.7 community edition running via docker.

My model snippet:

module.exports = {
...
"fieldName": "datetime"
...
}

My code snippet:

...
user.update({
    id: 'someid',
    fieldName: new Date()
})
...

But joi seems to be throwing this error: Error [ValidationError]: child "fieldName" fails because ["fieldName" must be an instance of "DateTime"]

Any help is appreciated.

Answer 1

It's in the driver try this.

const neo4j = require('neo4j-driver')
const getDateTime = d => {
  return neo4j.default.types.DateTime.fromStandardDate(d); // Example: d = new Date();
}

And use getDateTime function to get Datetime format.

Answer 2

maybe because it should be new Date(). Because it's not actually creating a new instance by calling the constructor and is instead a reference to the constructor.
