Clear db with mongoid3

mongoid, mongoid3

Solution

Output of `rake -T`

rake db:drop           # Drops all the collections for the database for the current Rails.env
..
rake db:mongoid:drop   # Drops the database for the current Rails.env
rake db:mongoid:purge  # Drop all collections except the system collections
..
rake db:purge          # Drop all collections except the system collections

Problem

I like to perform a set up before each time I run a unit test and clear my mongo db, how do I do it with mongoid? I found some links about it while googling but nothing seemed to work.
