It could have been like this by design, but it's pretty common to want to invoke callbacks for atomic updates. A valid scenario is invalidating a cache (see https://github.com/dblock/mongoid-cached-json/issues/7).
If not invoking before_save/update on an inc is by design, maybe there should be a built-in callback for inc or similar atomic operations?
require 'spec_helper'

|
|
class Gadget
|
include Mongoid::Document
|
|
|
field :count, type: Integer
|
before_update :called
|
before_save :called
|
|
|
def callback_count
|
@callback_count
|
end
|
|
|
def called
|
@callback_count = @callback_count.to_i + 1
|
end
|
end
|
|
|
describe "inc" do
|
it "calls the callback" do
|
gadget = Gadget.create!
|
gadget.callback_count.should == 1 # before_save
|
gadget.update_attributes!({ count: 10 })
|
gadget.callback_count.should == 3 # before save and update
|
gadget.inc(:count, 1)
|
gadget.callback_count.should == 4
|
end
|
end
