Having trouble using playlist_add_items fn for AuthCodeSpotify. Cannot figure out 'items' type.

[ultrex22]

I'm having trouble figuring out what exactly I need to pass to this method. I have looked at the docs and examples and the source code. I think it wants a trait object but I'm unsure how to accomplish this. I have a Vec of TrackId's I was trying to pass in, but it's not happy, lol.

the error:

type mismatch resolving <&Vec<TrackId> as IntoIterator>::Item == &dyn PlayableId E0271
expected trait object dyn PlayableId, found struct TrackId
Note: expected reference &dyn PlayableId found reference &TrackId
Note: required by a bound in playlist_add_items

this is the code causing the issue:

async fn create_playlist(spotify: &AuthCodeSpotify, track_id_list: Vec) {
let id = UserId::from_id(USER_ID).expect("Error creating UserId");
let new_playlist = spotify
.user_playlist_create(&id, "test_list", Some(false), None, Some("test list"))
.await
.expect("error creating playlist");
spotify
.playlist_add_items(&new_playlist.id, &track_id_list, None)
.await
.expect("error adding items");
}

Any suggestions would be welcome. Thank you!

You need to convert TrackId to &dyn PlayableId with as. This is because you can also add episodes to a playlist, so the method has to be "generic". This seems to work:

async fn create_playlist(spotify: &AuthCodeSpotify, track_id_list: Vec<TrackId>) {
    let id = UserId::from_id(USER_ID).expect("Error creating UserId");
    let new_playlist = spotify
        .user_playlist_create(&id, "test_list", Some(false), None, Some("test list"))
        .await
        .expect("error creating playlist");
    let playable_id_list = track_id_list
        .iter()
        .map(|track| track as &dyn PlayableId);
    spotify
        .playlist_add_items(&new_playlist.id, playable_id_list, None)
        .await
        .expect("error adding items");
}

Note that track_id_list: Vec didn't specify a generic parameter for Vec either, I imagine that was Vec<TrackId>.

Oh thank you so much for replying and the suggestion of code. You are correct it was a vector of track IDs. I see what you've done in the code that makes sense I will give that a try. I think I can also probably do the conversion in the method where I'm creating the list initially but I'm not sure about that maybe I'll give it a try. Well I've been watching reading and studying rust and involved with it basically on a daily basis I have had very little personal time to sit down and actually code until very recent. So I know that a lot of the hurdles I'm running into are just inexperienced / beginner issues but I definitely appreciate the time and the response.

No worries, best of luck with your coding learning!

I have the basics of the program working now. Thank you!
Another question I should have asked before. Is there a way to add the year of release to the search method?

[marioortizmanero]

It seems like our link to the reference documentation was broken. Here's the new one: https://developer.spotify.com/documentation/web-api/reference/#/operations/search. It seems like the year parameter would work?

I've fixed this in #353.

Good evening. It took me a little bit to figure out what I was looking at in this email. Looks like coincidentally to my question you realized one of the links was not working properly or incorrect and you put the fix in or pull request for it I guess I should say. So then I read everything carefully again and I realized I was assuming something false regarding my program and the specific API for the search function. I see I can structure my query to include the additional filters one of them being year. For some reason in my head I was confusing the return type parameter of the search method with the string thinking I could only include certain things in the request string if that makes any sense at all. So I'm going to take a look at the link and try and put myself together a search query with the year. Thank you for the time and the effort and the response! Ron Brilhante
