我正在使用下面的代码尝试从 Neo4jClient 调用 TimeTree。
其他简单的调用工作,但这个只是什么都不做。没有错误,也没有新的时间对象。
public class Trip
{
public long Id { get; set; }
public string Name { get; set; }
}
public class UUID
{
public long Value { get; set; }
}
public class TimeStamp
{
//public long Id { get; set; }
//public string Name { get; set; }
public long time { get; set; }
}
public class User
{
public long Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public string Email { get; set; }
}
class Program
{
static void Main(string[] args)
{
var client = new Neo4jClient.GraphClient(new Uri("http://localhost:7474/db/data"), "neo4j", "password");
client.Connect();
client.Cypher
.Match("(n)")
.DetachDelete("n")
.ExecuteWithoutResults();
var newUser = new User { Id = 456, Name = "Jim" };
client.Cypher
.Create("(user:User {newUser})")
.WithParam("newUser", newUser)
.ExecuteWithoutResults();
var newTrip = new Trip { Id = 001, Name = "Antibes" };
client.Cypher
.Match("(traveller:User)")
.Where((User traveller) => traveller.Id == 456)
.Create("(traveller)-[:TRAVELLING]->(travelling:Trip {newTrip})")
.WithParam("newTrip", newTrip)
.ExecuteWithoutResults();
var tstamp = client.Cypher
.Match("(trip:Trip)")
.Where((Trip trip) => trip.Name == "Antibes")
.With("trip AS tripToLink")
.Call("ga.timetree.events.attach({ node: 'tripToLink', time: 1483828451000, relationshipType: \"ARRIVING_ON\"})")
.Yield("node")
.Return(node => new { TimeStamp = node.As<TimeStamp>() });
以下在 Shell 中确实有效:
MATCH (trip:Trip)
WHERE trip.Name = "Antibes"
WITH trip
CALL ga.timetree.events.attach({node: trip, time: 1483828451000 , relationshipType: "ARRIVING_ON"})
YIELD node RETURN node
