Locations module: Implement the backend service

After Locations module: Implement the view model class of the Locations module web service, you need to create the backend service. To do so:

1. In Visual Studio, in the LocationsModule project, open the context menu of the folder Web and click Services.
   Click Add » Class.
2. Name the class file LocationsBackendService.cs and click Add.
3. Open the file LocationsBackendService.cs.
4. Add the following using statements:
   • using Telerik.Sitefinity.Modules;
   • using LocationsModule.Model;
   • using LocationsModule.Web.Services.Data;
   • using LocationsModule.Data;
   • using Telerik.Sitefinity.Modules.GenericContent;
5. Make the LocationsBackendService class inherit the ContentServiceBase<LocationItem, LocationItemViewModel, LocationsManager> class:
   public class LocationsBackendService : ContentServiceBase<LocationItem, LocationItemViewModel, LocationsManager>

   {

   }
6. Implement the abstract members of the ContentServiceBase in the following way:
   public override IQueryable<LocationItem> GetChildContentItems(Guid parentId, string providerName)

   {

       throw new NotImplementedException();

   }

    

   public override LocationItem GetContentItem(Guid id, string providerName)

   {

       return this.GetManager(providerName).GetLocation(id);

   }

    

   public override IQueryable<LocationItem> GetContentItems(string providerName)

   {

       return this.GetManager(providerName).GetLocations();

   }

    

   public override LocationsManager GetManager(string providerName)

   {

       return LocationsManager.GetManager(providerName);

   }

    

   public override LocationItem GetParentContentItem(Guid id, string providerName)

   {

       throw new NotImplementedException();

   }

    

   public override IEnumerable<LocationItemViewModel> GetViewModelList(IEnumerable<LocationItem> contentList, ContentDataProviderBase dataProvider)

   {

       var list = new List<LocationItemViewModel>();

    

       foreach (var location in contentList)

           list.Add(new LocationItemViewModel(location, dataProvider));

    

       return list;

   }
