...r_item_test.rb:31]: <-115.5> expected but was <-113.44>. 3 tests, 6 assertions, 1 failures, 0 errors So changing the amount on a transaction (RegisterItem) should change the current balance of an account. Here''s the relevent callbacks: REGISTER_ITEM UPDATE CALLBACKS: def before_update account.balance -= amount account.save end def after_update account.balance += amount account.save end So the idea is that before the transaction is updated i subtract the amount of the transaction back from the account, and then add the new amount back on. It looks like...

Hi, I''m doing a <model_name>.update(....) but I''m noticing that my before_update callback is not being called. If I do a find and then a save!, I notice that it is called. The problem with a find and save in my case is that I''m not able to set all my attributes in one shot by saving params["user"] and since I can''t do this, my overloaded equa...

In one of the models I perform some operation. For simplicity let''s assume that I populate column ''b'' with column ''a'' * 2. def before_update self.b = self.a * 2 end In my fixture I set values for a. first: id: 1 a: 10 Whe I run the test before_update is never invoked when rails populate the test table with the data from fixture. In development mode from the browser everything works fine. Any idea why in test the berfo...

Don''t know why, but cant seem to get this to work for me. I have a phone number field for an addressbook. In the addressbook model I have a before_update declaration that says the following: I''d like to be able to remove all special characters (just numbers please), but this doesn''t want to work for me. before_update :format_phone def format_phone self.phone = self.phone.to_s.gsub(/\D/, "") end The following wor...

Hi all, here is the challenge: I have this validation method, that basically prevents an object which billed = true to be updated: def before_update if read_attribute(:billed) errors.add_to_base(''This service has already been billed for'') end !read_attribute(:billed) end The above code does not work in case I do something like: object = Model.find(:first) object.billed = true object.save because in my...

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

How do I make this work? Thanks, Jack...

...moved from the system. I need to protect against this both when deleting a user and when editing a user as you can revoke a user''s administrator privileges via a form. User belongs_to :account. Account has_many :Users I was thinking that the best way to do this would involve either before_update and before_destroy or a validation. I think I know how to write the before_delete as that just involves knowing which user you are going to delete and checking if its account has more than one administrator. I am unsure how to write before_update as that requires not only knowing which use...

I want to include common auditing functionality in my models. This involves storing the changes made to a model in a seperate table : I have created the functions in an Audit module : module Audit before_update :before_changes after_update :after_changes def before_changes old=self.class.find(id).attributes @changes=[] attributes.each do |key, val| if val != old[key] change = Change.new(:primary_key_id=>id, :table=>self.class.table_name,...

Hi all, I''ve add :before_update event to my model Before updating a record I want to check if new attributes differ to old attr. My question is how to retrieve old attributes in :before_update event ? thanks -- gratis egold 1$ http://shegold.com/

...ormat? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where is the appropriate place to do the conversion from dollars to cents? I initially was thinking of doing the conversion in before_create or before_update, but again, it seems like the value is truncated as described above. Thanks. Ken

Hi I noticed that if in my code I use the following: Photo.update_all("title = ''Ruby rocks'' ", "id IN (#{@photo_ids})") All my objects are properly updated but none of the filters/callbacks are triggered. Is that what''s expected? I have a before_update filter set on the Photo class and it gets totally ignored, I guess the only way to solve this issue is to enumerate through the objects and update them one after the other :( Thanks, -Matt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscri...

...s that I also want the behaviour of the created_on and updated_on columns, that get modified automatically before saving. The problem is that I have my own "save" method and it does not work (remember this is not a real ActiveRecord model). I''ve tried to set the before_create and before_updated methods but they does not work (see code below). So… is there any way to do it automatically?

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

Hi, Very quickly, I''m having trouble calling my before_save ro before_update callbacks when I do something like User.update(id, params["user"]). I notice that Rails is calling after_save but for some reason it doesn''t call the before_save or before_update callbacks. Any thoughts would be appreciated. Thanks. -- Posted via http://www.ruby-forum...

Hi, I''m looking at ways to encrypt email addresses rather than storing them directly in the database. There are several ways that it could be done. I could make an Encrypter class and use before_update, etc. Or I could set up an updatable VIEW in mySql. (I guess triggers might be another possibility.) However, what I would really LIKE to do is use the handy AES_ENCRYPT and AES_DECRYPT functions in mySql. If I were doing this with straight sql, I would just use INSERT INTO myTable...

Neither @user or user is present, nor do I have any way to get the user_id. User is identified in my ApplicationController by a filter which is available in all my controllers. However, I have absol...

First off, I''m not trying to spec attachment_fu, I know it''s been tested. But, I added some code to that model that I do need to test. Basically, I need to somehow fulfill the "uploaded_data" property so I can actually run my tests(otherwise they fail because of validations). The "uploaded_data" field is what would grab the multipart data from form. Here
