MongoDAO
Info
MongoDAO is the core of this framework. The DAO Pattern simplifies database usage.
The MongoDAO object holds a reference to a MongoCollection and adds functions for easy collection handling.
Features
- MongoDAO Base (Drop, Index, Count)
- MongoDAO CRUD (Create, Insert, Delete)
- MongoDAO Search (Search, Distinct, Aggregate)
Usage
A DatabaseProvider is needed.
scala
val provider = DatabaseProvider.fromPath("dev.mongocamp")Create DAO
WARNING
Since Version 3.0.0 with Scala 3 support, we use Circe for automatic case class conversion. In the most cases, you can use the generic auto import. More Information about Circe can be found here.
A Type Parameter is used for automatic Document to Class conversion.
