Keeping attributes of two models in sync
Hi, I have a Product and a corresponding Keyword (1:1 via belongs_to and has_one). I want to ensure, that two attributes (:name) of the two models alway stay in sync. What''s the easiest way to accomplish that? I did play around with before_/after_save hooks and with AR::Observers but in the end I''d always get infinite recursion... Thanks, Timo

Determine if attributes changed?
Is there a way to determine if attributes were changed? Let''s say in the before_save or after_save method? Thanks for your help.

When after_save isn't after the save....
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

after_save -- stack level too deep
Hi all, I''m running into a brick wall trying to figure out my problem here. I have a model that has a boolean property called "paid". I''d like to add the following to my model: def after_save self.amount == self.splits.sum(:amount) ? self.update_attribute (:paid, true) : self.update_attribute(:paid, false) end The problem is, when I do this I get an error that

How to skip password validation when updating other fields?
Besides the hashed password, which is saved to db, I have two password-attributes in my User model: attr_accessor :password, :password_confirmation I have validations on these attributes, and I need them to work both on create and update, since I have pages for changing and resetting the password. Now when I want to update just the user''s login name, I guess I have the next

Suggestion: `before_save on: :create` should either work or raise an exception
There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

callback executed like after_save but after transaction
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. In the following situation this is fine: # MyModel def after_save `/usr/local/bin/update_models -i #{self.id}` end # controller

How do I stop a column being updated by model.save?
One of my models has a column that is updated very frequently from a separate process, so it is important that when a record is saved in rails, this column should be left alone. In the update method of the controller I have: @record = MyModel.find(params[:id]) @record.update_attributes(params[:my_model]) params[:my_model] doesn''t have a reference to the column I''m talking

Validation question
Hi all, Is there a way to invoke validations at times other than save, create and update? I know that I can do this by writing my own validation checks using errors.add_[blah], but I''d like to leverage the existing validation code. What I have is two sets of fields in a record, set A and set B. Both sets must be validated on record create. However, the trouble is that after

update_attribute and validations
Just in case it saves someone else the several hours of insanity I just went through, update_attributes will not save unless the model validations are satisfied, but update_attribute (the singular form) will save the attribute to the database even if the model validations would fail! This appears to be a feature, not a bug (http://api.rubyonrails.com/classes/ActiveRecord/Base.html) although

after_(read|find) callback?
I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

calling save in after_create hook
Scenario: I''m creating an image file upload service for my web site. As well as saving the actual file I also need to create a database record for the file. I would like to name the file after the record id, but I also need to save some attributes of the image (width/height/mime_type etc) which I can''t discover until after the file is created. The Problem: 1) The id is not

Very strange after_save problem. Please help.
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

Consequences of overriding update_attribute to force validation?
I know the debate of whether this should validate has been rehashed many times. My question is, what are the consequences of overriding this method to force validation? Will this break fundamental things? Will it break plugins? Is there a reason not to have a strict validation option? In my code I will never use this as I consider it a terribly broken method, but some gems use it and in one case

after_save deletes is an exception is raised?
Does after_save in a model delete if an exception is raised in there? I simply did def after_save raise ''hmmm'' end and it raised the exception but there was nothing in the database. I removed that entire method and its in the database. Is this correct? Thank You, Ben Johnson E: bjohnson@contuitive.com -------------- next part -------------- An HTML attachment was
