Mongomapper remove a collection

remove_collection.md

You have a collection of objects in you MongoDB like this here:

class Student
  include MongoMapper::Document
  key :name, String, :required => true
  key :firstname, String, :required => true
  key :course, String
end

To clean up your database you can either do this:

Student.all.each { |s| s.destroy }

or, and this is possibly a lot faster:

Student.collection.remove
