Nested object mapping

[bednart]

Hi,

I would like to know if it is possible to configure Mapperly to map objects below. I would like to skip Actions object in target. I tried static mapper but it was not applied.

public sealed record Source
{
    public required ICollection<RewardItem> Rewards { get; init; }

    public sealed record RewardItem
    {
        public required string Id { get; init; }
        public Actions? Actions { get; init; }
    }

    public sealed record Actions
    {
        public CompleteActionUrl? Complete { get; init; }
    }

    public sealed record CompleteActionUrl
    {
        public required string Method { get; init; }
        public required string Url { get; init; }
    }
}

public sealed record Target
{
    public required ICollection<RewardItem> Rewards { get; init; }

    public sealed record RewardItem
    {
        public required string Id { get; init; }
        public CompleteActionUrl? Complete { get; init; }
    }

    public sealed record CompleteActionUrl
    {
        public required string Method { get; init; }
        public required string Url { get; init; }
    }
}

Here is a simple solution:

If you build it it shows expected errors with default mapper:

[Mapper]
public partial class ClaimedRewardsMappers
{
    public partial Target Map(Source output);
}

Thanks for help ;)

Add a private mapping method private partial Target.RewardItem Map(Source.RewardItem source); and ignore the actions on it [MapperIgnoreSource(nameof(source.Actions))], see docs.

Thanks for help. This is my final mapper which works ;)

[Mapper]
public partial class ClaimedRewardsMappers
{
    public partial Target Map(Source output);

    [MapperIgnoreSource(nameof(source.Actions))]
    [MapPropertyFromSource(nameof(Target.RewardItem.Complete), Use = nameof(MapComplete))]
    private partial Target.RewardItem Map(Source.RewardItem source);

    private static Target.CompleteActionUrl MapComplete(Source.RewardItem sourceItem)
        => new()
        {
            Method = sourceItem.Actions?.Complete?.Method ?? string.Empty,
            Url = sourceItem.Actions?.Complete?.Url ?? string.Empty
        };
}
