Overwriting OrganizationUnit table... #9903 | Support Center

murat.yuceer created 4 years ago

Hi,

I have a table that named Organization which inherited from OrganizationUnit that uses by ABP.

public sealed class Organization : OrganizationUnit
    {
        //some codes..
    }

And i had overwrite the table name by adding following configuration below :

namespace Kuys.EntityFrameworkCore.EntityFrameworkCore.Configurations.Organization.Organizations
{
    public class OrganizationUnitConfiguration : IEntityTypeConfiguration<OrganizationUnit>
    {
        public void Configure(EntityTypeBuilder<OrganizationUnit> builder)
        {
            builder.ToTable("Organizations", SchemaNames.Organization);
        }
    }
}

However, since when i upgrade my abp version to latest (core 5), i'm getting the following error messages on update-database operation.

System.InvalidOperationException: To change the IDENTITY property of a column, the column needs to be dropped and recreated.

Do you have any suggestion to solve this problem?
