Testimonials module: Create the fluent mappings

After you Testimonials module: Create the data model class, you need to create the specific metadata source. To do so:

1. In Visual Studio, in Solution Explorer, open the context menu of the Data folder and click Add » Class...
2. In the Name input field, enter TestimonialsFluentMetaDataSource.
3. Open the file TestimonialsFluentMetaDataSource.cs and add the following namespaces:
   using System.Collections.Generic;

   using Telerik.OpenAccess.Metadata.Fluent;
4. Change the class definition to:
   public class TestimonialsFluentMetaDataSource : FluentMetadataSource

   {

    

   }
5. Create the MapTestimonialsTable method by pasting the following code:
   private MappingConfiguration<Testimonial> MapTestimonialsTable()

   {

       // map to table

       var tableMapping = new MappingConfiguration<Testimonial>();

       tableMapping.MapType().ToTable("sf_testimonials");

    

       // map properties

       tableMapping.HasProperty(t => t.Id).IsIdentity(Telerik.OpenAccess.Metadata.KeyGenerator.Guid);

       tableMapping.HasProperty(t => t.Name).HasLength(255).IsNotNullable();

       tableMapping.HasProperty(t => t.Summary).HasLength(255).IsNotNullable();

       tableMapping.HasProperty(t => t.Text).HasColumnType("varchar(max)");

       tableMapping.HasProperty(t => t.Rating).IsNotNullable();

       tableMapping.HasProperty(t => t.DatePosted).IsNotNullable();

       tableMapping.HasProperty(t => t.Published).IsNotNullable();

       tableMapping.HasProperty(t => t.UrlName).IsNotNullable();

    

       return tableMapping;

   }
6. Override the FluentMetadataSource methods by pasting the following code:
   protected override IList<MappingConfiguration> PrepareMapping()

   {

       var mappings = new List<MappingConfiguration>();

       var testimonialMapping = MapTestimonialsTable();

       mappings.Add(testimonialMapping);

       return mappings;

   }

You inherit from FluentMetadataSource and reuse the functionality in the method. In addition, you override the PrepareMapping method. The MapTestimonialsTable method maps the testimonial class to a database table.
