Rails assoication

In rails :

I Need to save every activity of any model which are associated with One Model.

For example:

I have a User model that is associated with some others model.Then if any updatio开发者_StackOverflow社区n ,insertion or select query fire on those models,It will be save as a activity in activity_log model, this table has a foreign key of user id .

Please give me idea how it can be possible without writing a function in ApplicationController

Thanks in advance for any guidance.

i don't know much about it, but i think you can use "active record callbacks". here is the link http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html

There are a few existing solutions that you can build on:

• Activity
• acts_as_protocolable
• activity_stream
