dev_to_prod.js

// For a collection "things" that has multiple documents of the form:
// { "_id" : ObjectId("4e5c47d1b0207a1ad3000001"),
//   "filename" :  "uploads/development/user/4dbf2b0ab0207a2e8a000001/avatar/avatar.png",
//   "other_data" : "foo"
// }, etc.
// we want to replace "development" in "filename" with "production".
// Run via mongo shell:
db.things.find().forEach(function(e) {
  var parts = e.filename.split('development');
  e.filename = parts[0] + 'production' + parts[1];
  db.things.save(e);
});
