you can check this document to know how to add a custom filter.

https://abp.io/docs/latest/framework/infrastructure/data-filtering

I have already gone through the documentation when i try to keep the below code in dbcontext getting no suitable method to overload error on CreateFilterExpression method

protected bool IsBranchFilterEnabled => DataFilter?.IsEnabled<IBranchEntity>() ?? false;

protected int? CurrentBranchId => BranchContext?.CurrentBranchId; 

protected override bool ShouldFilterEntity<TEntity>(IMutableEntityType entityType)
{
    if (typeof(IBranchEntity).IsAssignableFrom(typeof(TEntity)))
    {
        return true; // Apply filter to all entities implementing IBranchEntity
    }

    return base.ShouldFilterEntity<TEntity>(entityType);
}

protected override Expression<Func<TEntity, bool>> CreateFilterExpression<TEntity>(ModelBuilder modelBuilder)
{
    var expression = base.CreateFilterExpression<TEntity>(modelBuilder);

    if (typeof(IBranchEntity).IsAssignableFrom(typeof(TEntity)))
    {
        // Build the filter for BranchId
        Expression<Func<TEntity, bool>> branchFilter = e =>
            !IsBranchFilterEnabled || 
            (EF.Property<int?>(e, "BranchId") == CurrentBranchId || EF.Property<int?>(e, "BranchId") == null);

        // Combine the new filter with existing filters
        expression = expression == null ? branchFilter : QueryFilterExpressionHelper.CombineExpressions(expression, branchFilter);
    }

    return expression;
}

• Steps to reproduce the issue:

I need to create a custom filter to filter my entity based on BranchId. The BranchId will be received as a List<long> from the request headers or parameters. Here's the approach I followed:

1. Created IBranchEntity Interface:

   • Placed this interface in the Domain.Shared folder.
   • It includes a BranchId property, which I inherited in the relevant entity.

2. Defined IBranchContext Interface:

   • This interface includes a CurrentBranchId property to store the branch ID.
   • Implemented the interface in a BranchContext class in the Http.Host project with the necessary logic.
     

3. Entity Framework Filtering Logic:

   • Created a file in the EntityFramework folder to define filtering logic for entities.
     

4. Service Registration:

   • Registered the IBranchContext in the HostModule.cs under the ConfigureServices method as follows:

     context.Services.AddHttpContextAccessor();
     context.Services.AddScoped<IBranchContext, BranchContext>();
     

5. Database Context Changes:

   • Updated the ClinicServiceDbContext constructor to accept the IBranchContext.

     private readonly IBranchContext _branchContext;
     
     public ClinicServiceDbContext(
         DbContextOptions<ClinicServiceDbContext> options,
         IBranchContext branchContext
     ) : base(options)
     {
         _branchContext = branchContext;
     }
     
     protected override void OnModelCreating(ModelBuilder builder)
     {
          base.OnModelCreating(builder);
     
          builder.ConfigureClinicService();
     
          builder.ConfigureBranchFilterForEntities(_branchContext);
     }
     

After implementing the above, the filter is correctly identifying entities with the BranchFilter when the application is initially loaded. However, it is not being triggered for subsequent requests.
