DataSource.groovy

// You'll need configuration like this to get MongoDB up and running with Grails on AppFog
// This config will also work locally

grails {
    def vcap = System.env.VCAP_SERVICES
    def credentials = vcap ? grails.converters.JSON.parse(vcap)["mongodb-1.8"][0]["credentials"] : null
    mongo {
        host = credentials ? credentials.hostname : "localhost"
        port = credentials ? credentials.port : "27017"
        username = credentials ? credentials.username : null
        password = credentials ? credentials.password : null
        databaseName = credentials ? credentials.db : "your-localhost-db-name"
