Activities of "Mohammad"

Thanks for the Explaination and refund.

the using statement worked.

Why do I need to do the using for Unitofwork for the repository to work? can you explain? Is this a workaround or an actual solution?

I am getting the same error even after adding [UnitOfWork]

Hi

I am using it in Custom Tenant Resolver.

 public class AccessTokenTenantResolver : HttpTenantResolveContributorBase
    {
        public override string Name => "AccessToken";



        protected override async Task<string> GetTenantIdOrNameFromHttpContextOrNullAsync(ITenantResolveContext context, HttpContext httpContext)
        {
           

            IClientCredentialRepository clientCredentialRepository = context.ServiceProvider.GetRequiredService<IClientCredentialRepository>();

            string accessCode = httpContext.Request.Headers["Authorization"];

            if (!string.IsNullOrEmpty(accessCode))
            {
                var token = accessCode.Split(" ")[1];
                var tokenHandler = new JwtSecurityTokenHandler();
                var tokens = tokenHandler.ReadJwtToken(token);
                var client_id = tokens.Claims.FirstOrDefault(x => x.Type == "client_id").Value;
                var scopes = tokens.Claims.FirstOrDefault(x => x.Type == "scope").Value;

                if (scopes.Contains("Scope"))
                {
                    var client = await clientCredentialRepository.SingleOrDefaultAsync(x => x.ClientId == client_id);

                    if (client == null)
                        return await Task.FromResult<string>(null);

                   
                    return await Task.FromResult(client.TenantId.Value.ToString());
                }
            }

            return await Task.FromResult("37fb7b60-0ba6-8109-70b1-a049e5f25575");
        }
    }

I am getting this error when I try to use a EF Core Repository which is resolved using ServiceProvider in CustomTenantResolver.

Hi Maliming

So what would you suggest in my case for Seperate database per tenant?

1. Should I inherit all entities with IMultiTenant? If I do this then I'll have to store the tenantid in each table? Which doesnt serve the purpose of having separate databases per tenant.

The entity inherits IMultiTenant which means it is multi-tenant, and will try to get the connection string of the tenant.

In v4.0 It was working without Inheriting IMultiTenant https://github.com/abpframework/abp/blob/rel-4.0/framework/src/Volo.Abp.EntityFrameworkCore/Volo/Abp/Domain/Repositories/EntityFrameworkCore/EfCoreRepository.cs

I think its a change that has been made in the new version?
