please reference this question and answer https://support.abp.io/QA/Questions/3634/How-to-use-extra-properites-in-IQueryable

I'm trying to do the same thing, but in a module on a second dbContext. in the primary app module I have this and then I can access the extra property,

    ObjectExtensionManager.Instance.Modules()
                          .ConfigureIdentity(identity =>
                           {
                               identity.ConfigureRole(role =>
                               {
                                   role.AddOrUpdateProperty<string>("Code", property =>
                                   {
                                       property.Attributes.Add(new RequiredAttribute());

                                       property.Attributes.Add(new StringLengthAttribute(10)
                                       {
                                           MinimumLength = 1
                                       });
                                   });
                               });
                           });
                           

however in the module I get this error

System.InvalidOperationException: Translation of 'EF.Property<string>(EntityShaperExpression: Volo.Abp.Identity.IdentityRole ValueBufferExpression: ProjectionBindingExpression: EmptyProjectionMember IsNullable: False , "Code")' failed. Either the query source is not an entity type, or the specified property does not exist on the entity type.

please advise. Thank

    now, this is not the same error. my is

    Volo.Abp.Identity.IdentityRole ValueBufferExpression: ProjectionBindingExpression: EmptyProjectionMember IsNullable: False , "Code")' failed. Either the query source is not an entity type, or the specified property does not exist on the entity type.

    Yes, this is not the same error, but there are errors of similar logic. In the startup app module, StartupModuleDbContext is configured according to the new property. Still, since this configuration is not done in the dependent module, the dependent module ModuleDbContext does not know about the newly added property. In order for it to work as you said, this configuration must be done in the module.


    I may not have fully understood the problem. So if you think my observations are wrong, please provide more details.
