SDL Web 8 - Content Model in DD4T 2 (.NET)

This is a personal reference guide which I use to remind myself the different types of attributes available in DD4T 2 that I can use for my models.

Basic

[ContentModel("basic", true)]
public class Basic : IViewModel
{
    [TextField(FieldName = "text_field")]
    public string TextField { get; set; }
 
    [RichTextField(FieldName = "rich_text_field")]
    public MvcHtmlString RichTextField { get; set; }
 
    [LinkedComponentField(FieldName = "linked_component_field", LinkedComponentTypes = new[] { typeof(GeneralContent) })]
    public IViewModel LinkedComponent { get; set; }
 
    [KeywordKeyField(FieldName ="keyword_key_field")]
    public string KeywordKeyField { get; set; }
 
    [MultimediaField(FieldName = "multimedia")]
    public IMultimedia Multimedia { get; set; }
 
    [TextField(FieldName = "text_field_bool", IsBooleanValue = true)]
    public bool BoolTextField { get; set; }
 
    [NumberField(FieldName = "number_field")]
    public double NumberField { get; set; }
 
    [DateField(FieldName = "date_field")]
    public DateTime DateField { get; set; }
 
    [ComponentId]
    public TcmUri ComponentId { get; set; }
}
 
[ContentModel("general_content", true)]
public class GeneralContent : IViewModel
{
    [TextField(FieldName = "text_field")]
    public string TextField { get; set; }
}

Embedded Schemas

[ContentModel("embedded_schemas",true)]
public class EmbeddedSchema : IViewModel
{
    [EmbeddedSchemaField(FieldName = "embedded_schema_field")]
    public EmbeddedSchemaItem EmbeddedSchemaItem { get; set; }
 
    [EmbeddedSchemaField(FieldName = "embedded_schema_field")]
    public List<EmbeddedSchemaItem> EmbeddedSchemaItems { get; set; }
}
 
[ContentModel("embedded_schema_item",true)]
public class EmbeddedSchemaItem : IViewModel
{
    [TextField(FieldName = "text_field")]
    public string TextField { get; set; }
}

Metadata

[ContentModel("basic", true)]
public class Basic : BasicMetadata
{
    [TextField(FieldName = "text_field")]
    public string TextField { get; set; }
}
 
[ContentModel("embedded_schema_item",true)]
public class BasicMetadata : IViewModel
{
    [TextField(FieldName = "text_field")]
    public string TextField { get; set; }
}

Extra

These attributes are available from the current version of DD4T 2. I’ve not used these yet so I’m keeping them here for future reference.
