Relationship Create

The GraphQL API examples below use the example schema described in the Relationships section of the book. The unique IDs for nodes and relationships in the examples below may differ than other sections and chapters of the book.

• Between Existing Nodes
• From an Existing to a New Node

Between Existing Nodes

The GraphQL query below creates a new membership relationship between two existing nodes, adding alistair@example.com to the Warpforge projct.

mutation {
  OrganizationMembersCreate(
    input: {
      MATCH: { name: { EQ: "Warpforge" } }
      CREATE: {
        joinDate: "2022-01-28",
        dst: { User: { EXISTING: { email: { EQ: "alistair@example.com" } } } }
      }
    }
  ) {
    id
    joinDate
    src {
      id
      name
    }
    dst {
      ... on User {
        id
        email
      }
    }
  }
}

The output is as follows.

{
  "data": {
    "OrganizationMembersCreate": [
      {
        "id": "21173765-b2a3-4bb1-bfa7-5787ef17d6a8",
        "joinDate": "2022-01-28",
        "src": {
          "id": "85faa40f-04a8-4f0a-ae44-804604b4ef4c",
          "name": "Warpforge"
        },
        "dst": {
          "id": "de5e58cd-eb5e-4bf8-8a7a-9656999f4013",
          "email": "alistair@example.com"
        }
      }
    ]
  }
}

From an Existing to a New Node

The GraphQL below creates a new membership relationship from an existing organization to a newly created user.

mutation {
  OrganizationMembersCreate(
    input: {
      MATCH: { name: { EQ: "Warpforge" } }
      CREATE: {
        joinDate: "2022-01-28",
        dst: { User: { NEW: { email: "constantine@example.com" } } }
      }
    }
  ) {
    id
    joinDate
    src {
      id
      name
    }
    dst {
      ... on User {
        id
        email
      }
    }
  }
}

The output is as follows.

{
  "data": {
    "OrganizationMembersCreate": [
      {
        "id": "3ab33be6-16a3-4e50-87b5-3bb7d195ea54",
        "joinDate": "2022-01-28",
        "src": {
          "id": "85faa40f-04a8-4f0a-ae44-804604b4ef4c",
          "name": "Warpforge"
        },
        "dst": {
          "id": "c2b71308-2fd7-4d43-b037-30ec473e90a5",
          "email": "constantine@example.com"
        }
      }
    ]
  }
}
