DB Context

A DB Context will store the ModelContext's data into a relational database. The Slick library is used to map to the underlying DB.

The quickest way to make a ModelContext for the DB is to use the Vasat macro annotation @DBAuto

@JSONModel // Makes the mode have a JSON representation
case class Article(
    name:String,
    category:String,
    author:Ref[Author],
    datePosted:Date,
    active:Boolean
) extends PublicACL

@DBAuto // generates the ModelContext
class ArticleRepo extends DBContext[Article,SlickBaseTable]

Internally this macro will define the slick Table as well as mappings to and from the Model definition to the slick table.

Behind the scenes the macro populates a DBModelContext and a SlickSearchable which allow for both search and read/write/delete.

Without the macro, a ModelContext mapping to the DB can be achived, but will require many lines of code and a knowledge of Slick.
