My mutation as follows
mutation createNotes($content:String!,$entityId:String!,$entityType:String!,$mentionUserId:String!
,$mentionUserType:String!) {
createNote( note: {
content: $content
entityId: $entityId,
entityType: $entityType
mentionedUserIds: [{
id: $mentionUserId
type: $mentionUserType
}]
} ) {
id
}
}

My mutation call from activity
val response = apolloClientNotes.mutation(
CreateNotesMutation(
content=content,
entityId = entityId,
entityType=notesEntity,
mentionUserId=mentionUserId,
mentionUserType=mentionUserType
)
).execute()

I need to pass the mentionedUserIds as array of objects, I don’t know how to pass.

Hi!

Instead of having your GraphQL mutation accepting a String! argument, make it accept a list of your input type. Then in its body, pass the list directly.

So, assuming the input type is named MentionUserId, something like:

mutation createNotes($content: String!, $entityId: String!, $entityType: String!, $mentionUserIds:[MentionUserId!]!) {
  createNote( note: {
    content: $content
    entityId: $entityId,
    entityType: $entityType
    mentionUserIds: $mentionUserIds
) {
  id
}

Hope this helps!

Hi Benoit,
How can I pass the list from the api call, as json? will that work?

val response = apolloClientNotes.mutation(
CreateNotesMutation(
content=content,
entityId = entityId,
entityType=notesEntity,
mentionUserIds = mentionUserIds
)
).execute()

mutation createNotes($content:String!,$entityId:String!,$entityType:String!,$user_array: [NoteMentionedUserDTO!]!) {
createNote( note: {
content: $content
entityId: $entityId,
entityType: $entityType
mentionedUserIds: $user_array
} ) {
id
}
}

my schema contains the following
type Mutation {
createNote(note: NoteCreateDTO!): Note!
updateNote(id: String!, note: NoteUpdateDTO!): Note!
deleteNote(id: String!): String!
createVendorNote(note: VendorNoteCreateDTO!): Note!
updateVendorNote(id: String!, note: VendorNoteUpdateDTO!): Note!
deleteVendorNote(id: String!, note: VendorNoteDeleteDTO!): String!
}

input NoteCreateDTO {
content: String!
entityType: String!
entityId: String!
mentionedUserIds: [NoteMentionedUserDTO!]
createdByType: String
redirectURL: String
}

input NoteMentionedUserDTO {
id: String!
type: String!
}

You should be able to pass a list of NoteMentionedUserDTO to the generated Mutation, something like:

val response = apolloClientNotes.mutation(
    CreateNotesMutation(
        content = "",
        entityId = "",
        entityType = "",
        user_array = listOf(
            NoteMentionedUserDTO(id="", type=""),
            NoteMentionedUserDTO(id="", type=""),
            // etc.
        )
    )
).execute()

Hope this helps!
