update_all syntax?

[Amit Kumar]

Hi,

could someone shed light on the update_all syntax?

when i use Model.update_all(update, conditions) then mongoid adds conditions to the documents as attributes... :O

This updates EVERY document in the database:

Model.update_all(first_name: "Emmanuel")

This updates by conditions:

Model.where(last_name: "Zorg").and(:age.gt => 40).update_all(first_name: "Emmanuel")

update_all works with a single query or multiple queries???

It peforms a single $set with :multi => true operation under the covers.
