  Hello,

  For this, you can override the following CreateFilterExpression method in the MyAppDbContext class in the MyApp.EntityFrameworkCore project of your application as follows:

  protected override Expression<Func<TEntity, bool>>? CreateFilterExpression<TEntity>(ModelBuilder modelBuilder)
      {
          Expression<Func<TEntity, bool>> expression = null;
  
          if (typeof(ISoftDelete).IsAssignableFrom(typeof(TEntity)))
          {
              var softDeleteColumnName = modelBuilder.Entity<TEntity>().Metadata.FindProperty(nameof(ISoftDelete.IsDeleted))?.GetColumnName() ?? "IsDeleted";
              expression = e => !IsSoftDeleteFilterEnabled || !EF.Property<bool>(e, softDeleteColumnName);
              if (UseDbFunction())
              {
                  expression = e => AbpEfCoreDataFilterDbFunctionMethods.SoftDeleteFilter(((ISoftDelete)e).IsDeleted, true);
                  modelBuilder.ConfigureSoftDeleteDbFunction(AbpEfCoreDataFilterDbFunctionMethods.SoftDeleteFilterMethodInfo, this.GetService<AbpEfCoreCurrentDbContext>());
              }
          }
  
          if (typeof(IMultiTenant).IsAssignableFrom(typeof(TEntity)) && typeof(TEntity) != typeof(LanguageText))
          {
              var multiTenantColumnName = modelBuilder.Entity<TEntity>().Metadata.FindProperty(nameof(IMultiTenant.TenantId))?.GetColumnName() ?? "TenantId";
              Expression<Func<TEntity, bool>> multiTenantFilter = e => !IsMultiTenantFilterEnabled || EF.Property<Guid>(e, multiTenantColumnName) == CurrentTenantId;
              if (UseDbFunction())
              {
                  multiTenantFilter = e => AbpEfCoreDataFilterDbFunctionMethods.MultiTenantFilter(((IMultiTenant)e).TenantId, CurrentTenantId, true);
                  modelBuilder.ConfigureMultiTenantDbFunction(AbpEfCoreDataFilterDbFunctionMethods.MultiTenantFilterMethodInfo, this.GetService<AbpEfCoreCurrentDbContext>());
              }
              expression = expression == null ? multiTenantFilter : QueryFilterExpressionHelper.CombineExpressions(expression, multiTenantFilter);
          }
          
          return expression;
      }
  

  Then you need to replace the LanguageManagementDbContext from DI Container as in the picture below:

  Hi berkansasmaz,

  I've done the following as you mentioned, however the text in tenants are still different from what' we've set in host

  Changed host text (Recommended Realplays --changed to--> Your Recommended Realplays)

  old default value in en.json

  However, despite implementing code you provided, the tenant still sees different (old) text:

  After some testing, i did notice that language texts that do not have a base value in that language will cascade fine.

  I set value of Deutsch translation to "Guten Tag" in host, that seems to cascade to tenant fine. There is no value for HomePage:Title2 in the de-DE.json

  • When text is defined in en.json, it does not cascade down to tenant (even when updated by host)
  • When text is not defined in languagexxx.json file, and updated in GUI by host, it will cascade to tenants

  Hi,

  I think I misunderstood you at first. I understand your question better now. Can you add the following code to your Domain project and try again?

  [Dependency(ServiceLifetime.Singleton, ReplaceServices = true)]
  [ExposeServices(typeof(DynamicResourceLocalizer), typeof(IDynamicResourceLocalizer))]
  public class MyDynamicResourceLocalizer : DynamicResourceLocalizer
  {
      private readonly ICurrentTenant _currentTenant;
      
      public MyDynamicResourceLocalizer(IServiceScopeFactory serviceScopeFactory, IDistributedCache<LanguageTextCacheItem> cache, ICurrentTenant currentTenant) : base(serviceScopeFactory, cache)
      {
          _currentTenant = currentTenant;
      }
  
      public override LocalizedString GetOrNull(LocalizationResourceBase resource, string cultureName, string name)
      {
          using (_currentTenant.Change(null))
          {
              return base.GetOrNull(resource, cultureName, name);
          }
      }
  
      protected override LanguageTextCacheItem GetCacheItem(LocalizationResourceBase resource, string cultureName)
      {
          using (_currentTenant.Change(null))
          {
              return base.GetCacheItem(resource, cultureName);
          }
      }
  
      protected override Task<LanguageTextCacheItem> GetCacheItemAsync(LocalizationResourceBase resource, string cultureName)
      {
          using (_currentTenant.Change(null))
          {
              return base.GetCacheItemAsync(resource, cultureName);
          }
      }
  }

  Hi berkansasmaz

  Thank you, i've made both changes described

  • add MyDynamicResourceLocalizer
  • override the following CreateFilterExpression method in the MyAppDbContext (discussed earlier)

  and it works now. Really appreciate the support!

  Just an FYI, I think this ticket might be related to this other ticket which i saw: https://abp.io/support/questions/8916/Text-templates-Language-texts-for-all-tenants

  It might be worth linking that ticket here as this seems to solve the issue requested by the author (at least the part about language texts)
