[Question] Insert multiple objects at once with variables

Hey, thx for the awesome project!

I’m a hasura / graphql beginner and like to ask, if it is possible to insert multiple objects at once with graphql-request using variables and how it should look like.

I was able to successful insert a single entity like that:

  import { request } from 'graphql-request'
  const variables = { id: 123, name: "test" }
  const gql = `mutation insert_test(
    $id: Int!
    $name: String! 
  ) {
    insert_test(
      objects: {
        id: $id,
        name: $name
      }
    ) {
      returning {
        id
      }
    }
  }`
  const res = await request(HASURA_URL_GRAPHQL, gql, variables)

But when changing the variables to an array i got an error.

  import { request } from 'graphql-request'
  const variables = [{ id: 123, name: "test" }, { id: 456, name: "test1" }]
  const gql = `mutation insert_test(
    $id: Int!
    $name: String! 
  ) {
    insert_test(
      objects: {
        id: $id,
        name: $name
      }
    ) {
      returning {
        id
      }
    }
  }`
  const res = await request(HASURA_URL_GRAPHQL, gql, variables)

Can someone give me a hint into the right direction here? Thx in advance!

@divramod You can change your variables input to be the object type and it should be fine after that:

 import { request } from 'graphql-request'
  const variables = [{ id: 123, name: "test" }, { id: 456, name: "test1" }]
  const gql = `mutation insert_test($objects: [test_insert_input!]!)
  ) {
    insert_test(
      objects: $objects
    ) {
      returning {
        id
      }
    }
  }`
  const res = await request(HASURA_URL_GRAPHQL, gql, variables)

To get the exact type name there (test_insert_input) you can use the “docs” tab on the hasura graphiql console 😃

Sure.

Here is a piece of code that let me achieve it.

The query: const INSERT_TAGS = gql mutation MyMutation($objects: [tag_insert_input!]!) { insert_tag(objects: $objects) { returning { id name user_id } } } ;

The code to run the query: function InsertNewTags(tags, curator_id) { return client .mutate({ mutation: INSERT_TAGS, variables: { objects: tags, }, }) .catch((error) => { console.log(error); }); }

In the tags parameter of the above function an array of objects is passed. tags = [{ name: values.selTags[a], user_id: values.curator_id },{ name: values.selTags[a], user_id: values.curator_id }]

I hope this helps.
