create record and associate it to another record in one request

[bilouw]

Hi,

Let's say i want to create a Post and associate it to an already created Comment. (in my example, Comment belongs_to Post and Post has_one Comment)
This is what i'm doing:

let post = new Post({ comment: new Comment})
post.comment.id = commentIdToAssociate
post.save({ with: 'comment.id' })

This code will create a new comment associated to the post with method: "create".
I don't want to create this comment, i want to associate it to my post (method: "update")

I want this kind of body:

"relationships": {
	"comment": {
		"data": {
			"id": "64520319-03be-4c29-b86b-199c1038ba23",
			"type": " comments",
			"method": "update"
		}
	},
}

How can i do that ?

Thanks.

Try this:

let comment = new Comment({ id: "123" })
comment.isPersisted = true
let post = new Post({ comment })
post.save({ with: 'comment.id' })

Just what i needed ! I did not understand that i should use isPersisted attributes to specify that the record already exist in DB.

Thanks for your help !

Also: Graphiti & Spraypaint are great tools to develop !
