Does anyone know how to disable a model’s callbacks?
I have a routine that increments a page_view counter for various model
objects in an after_filter in my ApplicationController. I call this:
increment_page_view()
Rather that checking through the trace array in each model callback for
“increment_page_view” I’d rather disable the callbacks from inside
increment_page_view() itself.
Seems like it should be possible, but don’t seem to be able to work it
out.
Anybody done this or have ideas on how to do it?
Thanks 
You shouldn’t do this from the filter in the controller. It’s skating on
the
edge of breaking MVC.
Make your own model
class MyBase < ActiveRecord::Base
def before_save
end
def before_update
end
def before_create
end
end
Then inherit any of your models from that.
If you wanted to do this from outside of the model (which I don’t think
is
good because you are tying models to controllers) you could experiment
with
disabling the callbacks on an instance of your model by using a module.
I
have not tested this at all… just writing this off the top of my head.
lib/disable_callbacks.rb
module DisableCallbacks
def before_save
end
def before_update
end
def before_create
end
end
environment.rb
require ‘disable_callbacks’
your controller’s filter
def increment_page_view
include DisableCallbacks
@my_model = MyModel.find :first
@my_model.extend DisableCallbacks
end
Does any of that make sense?
