Steps to reproduce the issue:

Hi,

A solution is created by using ABP Suite and upgraded to V8.3.0 via ABP Suite user interface.

Product entity is created.

2 user is created and assigned to registereduser role.

user1 is created a record into the Product entity via auto-generated page in .Web app.

It is needed to filter the records based on CreatorId .

A service method is created in the ProductsAppService.Extended.cs as follows :

    public async Task&lt;List&lt;Product&gt;> GetMyProductListAsync()
    {
        using (_dataFilter.Enable&lt;IMustHaveCreator&gt;())
        {
            return await _productRepository.GetListAsync();            
        }
    }

I couldn't find an appropriate usage of this implementation.

I will be very appreciated if anyone has a sample code or any advice.

Thanks

You can try:

... IRepository<Product, Guid> _productRepository;

public async Task<List<Product>> GetMyProductListAsync()
{
    using (_dataFilter.Enable<IMustHaveCreator>())
    {
        return await _productRepository.GetListAsync(x => x.CreatorId == CurrentUser.Id);            
    }
}

Thank you for a quick reply. If a parameter is used, data filtering doesn't affect to the result that means there is no need to use data filter implementation. Maybe I couldn't understand very well the use-cases of this concept. Does it effective only for dbcontext level?

You can try:

... IRepository<Product, Guid> _productRepository; 
 
public async Task<List<Product>> GetMyProductListAsync() 
{ 
    using (_dataFilter.Enable<IMustHaveCreator>()) 
    { 
        return await _productRepository.GetListAsync(x => x.CreatorId == CurrentUser.Id);             
    } 
}
