I have the following controller:
public class ModuleController : Controller
{
// GET: Modulo
public ActionResult GetModules()
{
return PartialView(Module.GetModulesForUser(ClaimsPrincipal.Current.Identities.First().Name));
}
}
and this returns the modules for a user
/// <summary>
/// Gets the modules activated for a user
/// </summary>
/// <returns>List of modules for the selected user</returns>
public static Tuple<string, List<Modulo>> GetModulesForUser(string identityname)
{
// It needs to be cached for every user because every user can have different modules enabled.
var cachekeyname = "ApplicationModulesPerUser|" + identityname;
var cache = CacheConnectionHelper.Connection.GetDatabase();
Tuple<string, List<Modulo>> modulosPorUsuarioDeDirectorioActivo;
//get object from cache
string modulosUsuariosString = cache.StringGet(cachekeyname);
//string modulosUsuariosString;
if (!string.IsNullOrEmpty(modulosUsuariosString))
{
modulosPorUsuarioDeDirectorioActivo = JsonConvert.DeserializeObject<Tuple<string, List<Modulo>>>(modulosUsuariosString);
return modulosPorUsuarioDeDirectorioActivo;
}
var extPropLookupNameModulos = $"extension_{SettingsHelper.ClientId.Replace("-", "")}_{"Modulos"}";
var client = AuthenticationHelper.GetActiveDirectoryClient();
var user = client.Users.GetByObjectId(identityname).ExecuteAsync().Result;
var userFetcher = (User)user;
var unitOfWork = new UnitOfWork();
var keyvaluepairModulos = userFetcher.GetExtendedProperties().FirstOrDefault(prop => prop.Key == extPropLookupNameModulos);
var idsModulos = keyvaluepairModulos.Value.ToString().Split(',');
var listaModulos= idsModulos.Select(idModulo => unitOfWork.ModuloRepository.GetById(Convert.ToInt32(idModulo))).ToList();
modulosPorUsuarioDeDirectorioActivo = new Tuple<string, List<Modulo>> ( identityname, listaModulos);
//convert object to json string
modulosUsuariosString = JsonConvert.SerializeObject(modulosPorUsuarioDeDirectorioActivo);
//save string in cache
cache.StringSet(cachekeyname, modulosUsuariosString, TimeSpan.FromMinutes(SettingsHelper.CacheModuleNames));
return modulosPorUsuarioDeDirectorioActivo;
}
However I need in the partial view to be able to access the Tuple and then render it.
model Tuple<string,List<xx.Models.GlobalAdmin.Models.Modulo>;
@foreach (var module in Model.Modules)
{
<i class="fa @(@module.ClaseFontAwesome)" title="@module.Nombre"></i>
}
However I get this error:
You can access to components of tuple by the Item1
, ...ItemN
properties.
Try this:
@foreach (var module in Model.Item2)
Tuple does not have a parameterless constructor which might be what's causing this issue. Why don't you create a single viewmodel that has a string and a list and pass it to the view? Ref MVC Custom ViewModel and auto binding
