I have the following data structure, and I'm attempting to remove an item from the 'artists' array.
[
{
"id": "56b26eeb4a876400011369e9",
"name": "Ewan Valentine",
"email": "ewan@test.com",
"artists": [
"56b26f334a876400011369ea",
"56b2702881318d0001dd1441",
"56b2746fdf1d7e0001faaa92",
],
"user_location": "Manchester, UK"
}
]
Here's my function...
// Remove artist from user
func (repo *UserRepo) RemoveArtist(userId string, artistId string) error {
change := bson.M{"artists": bson.M{"$pull": bson.ObjectIdHex(artistId)}}
fmt.Println(userId)
err := repo.collection.UpdateId(bson.ObjectIdHex(userId), change)
return err
}
I'm getting the following error:
{
"_message": {
"Err": "The dollar ($) prefixed field '$pull' in 'artists.$pull' is not valid for storage.",
"Code": 52,
"N": 0,
"Waited": 0,
"FSyncFiles": 0,
"WTimeout": false,
"UpdatedExisting": false,
"UpsertedId": null
}
}
