After_save in plugin

Dear list,
I am trying to override an after_save callback declared in main app
using plugin.
The main model class is:

class WorkHours < ActiveRecord::Base
@after_save_call_back_called=0
after_save :after_save_call_back
def after_save_call_back
logger.debug “after save called”
@after_save_call_back_called=1
end
end

And in my plugin (in the lib directory) :

module WorkHoursPatch

cattr_accessor

def self.included(base) # :nodoc:
base.logger.debug “inlcuded called”
base.extend(ClassMethods)
base.send(:include, InstanceMethods)
base.after_save.delete_if{
|callback| callback.method == :after_save_call_back
}
base.send(:after_save, :after_save_call_back_patched)
end

module ClassMethods

end

module InstanceMethods
def after_save_call_back_patched
logger.debug “overriden after save called”
@after_save_call_back_called=1
end

Wraps the association to get the Deliverable subject. Needed for

the

Query and filtering

def is_new

unless self.is_new.nil?

return self.is_new

end

return false;

end

end
end

Add module to Issue

WorkHours.send(:include, WorkHoursPatch)

The init.rb says
require ‘work_hours_patch’

All this should work and running the console I an see the old plugin
being deleted and the new one added.

Please help!
I am spending on this days!

I think your issue may be a mixup with class instance and instance
variables.

However, what’s the issue you are having with all this? Are you getting
any
error messages?

Thanks Tom ,
I have actually figured out the problem.
Seems like since the lib of the plugin is not reloaded on every request
but the main app is .The plugin override works for first request but the
original methods are restored the next one.
The solution that worked for me was wrapping our monkey-patch in a
callback.
