similar to: does after_save get called if failed save?

How to update attribute(s) and save a record instance without triggering the hooks: after_save, after_create, after_update? I know it''s possible with Record.update() but this is dynamic. Only receive the instance, without knowing its class (thus cannot call the class method update()). Or is there a way of knowing the class and calling the class method? Thank you. -- Posted via

Having one to many connection (for example post has many comments), what is the most efficient way of saving all comments when post is saved. Using after_save on Post would introduce the n+1 problem. Is there any way of saving the whole structure at once? -- Posted via http://www.ruby-forum.com/.

Hi, AFAIK after_create is called after_save if the entry does not exist in the DB. Is there a way to tell if a specific model is new or not in after_save? I have to do something like: def after_save add_to_history ''save'' end def after_create add_to_history ''create'' end However after_save is called when creating too. -- cheers, M.

I have a Production model, which represents a farmer''s crop. After create (via after_save) I call a method that creates one or more Supply models, which represent a week of anticipated product harvest. After each of those are created, a class method gets called that tries to match each new Supply with outstanding orders for the same time period. If a match is made, a transaction (an

I''m trying to add some code for my ActiveRecord class so that it is executed whenever an object is updated, this code is a seperate process that reads from the same table represented by my model class so when it runs it needs the database to be up to date.

I try to understand the following issue : - when creating a new User record, I use an UserObserver to trap the before_save call back and send an email def after_create(user) UserNotifier.deliver_signup_notification(user) end - Once created a user can ask for a password reset, which is also trapped by the UserOberver def after_save(user) UserNotifier.deliver_reset_password(user) if

Hi, there must be something wrong somewhere in my unit test because there''s a model I can''t have any callback executed on.

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to

I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

class User < AR end user = User.new Let''s say that I have a user instance with me. After this record is saved I want an after_save callback which would print the id of the record. The only catch is that I am not allowed to change the User class. How can I accomplish my goal? Is that even possible to add an after_save callback on a particular instance object. Any metaprogramming

It appears that when after_save is triggered, associations such as habtm haven''t been populated yet. Each association can have an :after_add callback, but my code needs to access multiple associations. Is there an explicit reason why after_save isn''t triggered after all of the associations have been populated? --~--~---------~--~----~------------~-------~--~----~ You received
