Hi this link is very helpful: <a class="postlink" href="https://www.aspnetzero.com/Documents/Extending-Existing-Entities#extending-non-abstract-entities">https://www.aspnetzero.com/Documents/Ex ... t-entities</a>

but i have the problem when extending AbpOrganizationUnits table

public class OrgChartExtend : OrganizationUnit
    {
        public virtual string DisplayCode { get; set; }
    }
public partial class Added_DisplayCode_To_OrganizationUnit : Migration
    {
        protected override void Up(MigrationBuilder migrationBuilder)
        {

            migrationBuilder.AddColumn< string > (name: "DisplayCode", table: "dbo.AbpOrganizationUnits", nullable: true, maxLength: 50);
        }

        protected override void Down(MigrationBuilder migrationBuilder)
        {
            migrationBuilder.DropColumn(name: "DisplayCode", table: "dbo.AbpOrganizationUnits");
        }
    }

and when i update this to the database error show this

    Hi,

    This is very strange. Can you check that if AbpOrganizationUnits table really exists on your DB or not ? Maybe it is deleted manually, is that possible ?

    Thanks.

    Hi i got work for create DisplayCode Field to the DB.

    i also update

    OrganizationUnitDto.cs Class

    [AutoMapFrom(typeof(OrganizationUnit))]
        public class OrganizationUnitDto : AuditedEntityDto<long>
        {
            public long? ParentId { get; set; }
    
            public string Code { get; set; }
    
            public string DisplayName { get; set; }
    
            public int MemberCount { get; set; }
    
            public string DisplayCode { get; set; }
        }
    

    then run nswag/refresh.bat file and also modify the angular side to display DisplayCode Field but when i run the page DisplayCode Field is empty

    i also check the service-proxies.ts file DisplayCode also show

    xport class OrganizationUnitDto { 
        parentId: number; 
        code: string; 
        displayName: string; 
        memberCount: number; 
        displayCode: string; 
        lastModificationTime: moment.Moment; 
        lastModifierUserId: number; 
        creationTime: moment.Moment; 
        creatorUserId: number; 
        id: number;
        constructor(data?: any) {
            if (data !== undefined) {
                this.parentId = data["parentId"] !== undefined ? data["parentId"] : null;
                this.code = data["code"] !== undefined ? data["code"] : null;
                this.displayName = data["displayName"] !== undefined ? data["displayName"] : null;
                this.memberCount = data["memberCount"] !== undefined ? data["memberCount"] : null;
                this.displayCode = data["displayCode"] !== undefined ? data["displayCode"] : null;
                this.lastModificationTime = data["lastModificationTime"] ? moment(data["lastModificationTime"].toString()) : null;
                this.lastModifierUserId = data["lastModifierUserId"] !== undefined ? data["lastModifierUserId"] : null;
                this.creationTime = data["creationTime"] ? moment(data["creationTime"].toString()) : null;
                this.creatorUserId = data["creatorUserId"] !== undefined ? data["creatorUserId"] : null;
                this.id = data["id"] !== undefined ? data["id"] : null;
            }
        }
    

    How can i solve this issue Thank you

    Hi,

    Can you change your AutoMapFrom attribute like this:

    [AutoMapFrom(typeof(OrganizationUnit), typeof(OrgChartExtend))]
    

    If you added DisplayCode field to database manually, it will create other problems in the future. If you did it manually, maybe we should fix it first.

    Thanks.

    How can i extend

    public class OrganizationUnit : FullAuditedEntity<long>, IMayHaveTenant
    {
      public OrganizationUnit(int? tenantId, string displayName, long? parentId = default(long?));
    }
    

    constructor to include my DisplayCode filed to be able to call , insert and update to the database

    and i also add this to the code but noting happen

    [AutoMapFrom(typeof(OrganizationUnit), typeof(OrgChartExtendCode))]
        public class OrganizationUnitDto : AuditedEntityDto<long>
        {
            public long? ParentId { get; set; }
    
            public string Code { get; set; }
    
            public string DisplayName { get; set; }
    
            public int MemberCount { get; set; }
    
            public string DisplayCode { get; set; }
        }

    hi

    I guess your connection string is different. Check that migration is being applied to the same database connection string
