I have added a new property to User class,

public List<ClaimedPosts> ClaimedPosts { get; set; }

Below is the class for claimed points class


public class ClaimedPosts : FullAuditedEntity<long>
    {
        public long UserId { get; set; }

        public string PostId { get; set; }

        [ForeignKey("UserId")]
        public User User { get; set; }
    }

When i try to save related data to the claimed posts it gives the below error,

Abp.Domain.Uow.AbpDbConcurrencyException
  HResult=0x80131500
  Message=Database operation expected to affect 1 row(s) but actually affected 0 row(s). Data may have been modified or deleted since entities were loaded. See http://go.microsoft.com/fwlink/?LinkId=527962 for information on understanding and handling optimistic concurrency exceptions.

    I added the above claimed posts class and added it as a list property in user class. A user can have many claimed posts. I tried to add a list to the user claimed posts property and it threw the error

    Sorry i cannot share the code.

    I managed to insert a record like below, but i am not sure if it is the correct approach,

    User user = await UserManager.GetUserByIdAsync(AbpSession.UserId.Value);

            List&lt;Point.ClaimedPosts&gt; claimedPosts = new List&lt;Point.ClaimedPosts&gt;();
        foreach (var post in posts)
        {
            await _claimPostRepository.InsertAsync(new Point.ClaimedPosts { UserId = user.Id, PostId = post.PostId });
        }
