Pointing to same node from different nodes

Users Dgraph
1 
type Customer {
    id: ID!
    personal_name: Name 
    father_name: Name 
    phone: [Phone] 
}

type Name {
    id: ID!
    first_name: String!
    last_name: String!
    middle_name: String
    full_name: String!
}




type Phone {
    id:  ID!
    number: String 
}

if the customer have same phone number it should point to same node but for me new nodes are getting created.

Hey @Deepak_Sharma,

Can you please share the mutation that you’re trying?

{
	
  "set":[
				{
					"dgraph.type":"Customer",
  				"personal_name":{
            "first_name": "Deepak",
            "last_name": "Sharma",
            "middle_name": "",
            "full_name": "Deepak Sharma"
					},
          "phone":{
						"number":"9513351889"
          	}
        },
				{
				"dgraph.type":"Customer",
  				"personal_name":{
            "first_name": "Deepak1",
            "last_name": "Sharma1",
            "middle_name": "",
            "full_name": "Deepak1 Sharma1"
        },
          "phone":{
						"number":"9513351889"
          	}
				}
		]	  
}

@matthewmcneely the motive is if the phone number already exits it should create edge to that type should not create a new node. can you help me with this

Right. The issue here is that the phone predicate is a simple list, people often confuse them for sets, but they are “stupid” arrays. Have a look at this thread for some discussion and a possible solution: How can I append element to array wiht graphql - #4 by matthewmcneely
