How to re-index a new RemoteImage of an item

[Sludge Vohaul 22]

Hi,

 

I want to programatically add a new backdrop image to an item and have it shown in the UI.

I have a problem to identify the image I've added, in order to re-index it to the first position.

 

That's what I do:

I add the image by providing it's type (e.g. backdrop) and it's URL:

var args = new Dictionary<string, string>
{
  {"Type", imageType.ToString()},
  {"ImageUrl", imageUrl.AbsoluteUri}
};

var url = client.GetApiUrl($"Items/{movieId}/RemoteImages/Download");
await client.PostAsync<EmptyRequestResult>(url, args)

There is no return value available. As an item can have multiple backdrop images, all I know is, that it has been appended to an internal list of backdrop images.

 

So in order to show the image in the UI, I have to move it to the first position of the backdrop list (index=0).

Therefore I need to get it's current index in the list:

var url = client.GetApiUrl($"Items/{movieId}/Images");
var imageInfos = await client.GetAsync<List<ImageInfo>>(url);
var lastBackdropIndex = imageInfos.Count(x => x.ImageType == ImageType.Backdrop) - 1;

After that, I have to move the image to index=0:

// Do not reindex if it's the only image (or no image at all).
if (lastBackdropIndex <= 0) return;

var args = new Dictionary<string, string>
{
  {"NewIndex", "0"}
};

var url = client.GetApiUrl($"Items/{movieId}/Images/{imageType}/{lastBackdropIndex}/Index");
await client.PostAsync<EmptyRequestResult>(url, args);

This seems to work, but, is based on the assumption, that the last image in the list is the one I have added. What if several users added an image in a small time frame? If I took the last one in the list it might not be "my" image.

 

How do I identify the image I have added, so that I don't have to assume "my" image is the last in the list?

You can't currently. It's something we'd have to add to the api. For now the best you can do is just make that assumption.

Ok, thanks for the info.
