SalatDAO

implicit manifest for ObjectType
implicit manifest for ID
implicit com.novus.salat.Context
Inner abstract class to facilitate working with child collections using a typed parent id - no cascading support will be offered, but you can override saves and deletes in the parent DAO to manually cascade children as you like.
Inner abstract class to facilitate working with child collections using a typed parent id - no cascading support will be offered, but you can override saves and deletes in the parent DAO to manually cascade children as you like.
Given parent class Foo and child class Bar:
case class Foo(_id: ObjectId, // etc ) case class Bar(_id: ObjectId, parentId: ObjectId, // this refers back to a parent in Foo collection // etc ) object FooDAO extends SalatDAO[Foo, ObjectId](collection = MongoConnection()("db")("fooCollection")) { // and here is a child DAO you can use within FooDAO to work with children of type Bar whose parentId field matches // the supplied parent id of an instance of Foo val bar = new ChildCollection[Bar, ObjectId](collection = MongoConnection()("db")("barCollection"), parentIdField = "parentId") { } }

Supplies the com.novus.salat.Grater from the implicit com.novus.salat.Context and ObjectType manifest
Supplies the com.novus.salat.Grater from the implicit com.novus.salat.Context and ObjectType manifest
com.novus.salat.Grater to serialize and deserialize ObjectType
If you are mixing and matching abstract and concrete DAOs, turn this on in the concrete DAOs to ensure that querying on a mixed collection will only yield results in the child collection.
