slick-mongo-light

Slick-style cross-library MongoDB query builder.

http://cvogt.org/slick-mongo-light

This is an early version. Expect gaps and breakages. PRs welcome.

slick-mongo-light is a project by one of Slick's core developers, but not actually technically related to the Slick database library. It is however inspired by it and allows Slick-style query building compatible with Casbah, ReactiveMongo, PlayJson and easy to integrate with others. slick-mongo-light is NOT type-safe.

Currently only supported are conditions. All supported operators can be seen here: http://cvogt.org/slick-mongo-light/api/0.2/#org.cvogt.slick_mongo_light.Implicits$$MongoExpressionExtensions

SBT settings (don't forget to include one supported Mongo client library):

libraryDependencies += "org.cvogt" %% "slick-mongo-light" % "0.2"

Getting started:

import org.cvogt.slick_mongo_light.Implicits._
import org.cvogt.slick_mongo_light.dialect.Casbah._ // or another dialect

// compare a top-level field
col.find(m"someField" === 1)

// compare a nested field
col.find(m"someField.nestedField" === 1)

// compare multiple nested fields
col.find(m"someField" -> {
  m"nestedField1" === 1 && m"nestedField2" === "foo"
})

// embed ordinary mongo queries
col.find(m"someField" -> {
  m"nestedField1" === 1 && MongoDBObject("nestedField2" -> MongoDBObject("$eq" -> "foo"))
})

// check existence in a list
col.find(m"someField" in List(1,2,3))

// more examples
col.find(m"someField".exists)

import org.cvogt.slick_mongo_light.expressions.Type
col.find(m"someField".isOfType(Type.Boolean))

col.find(m"someField" > org.joda.time.DateTime)
