similar to: When after_save isn't after the save....

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`,

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

Hey guys, Firstly, I''m new to the list and great work with backgroundrb, it''s sweet!!! I''ve just started noticing an issue and i''m wondering if there is a standard fix.

Can someone explain why a instance variable cannot be changed through an association under rspec/factory_girl? An example is in this gist<https://gist.github.com/2484336> .

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

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 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

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

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

I want to write a function that after an ActiveRecord saves successfully, can show me what the before and after values of a particular column are. Is this possible without creating a separate object before modifying the current one? -John

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

I''ve got a web-app currently partially working. The user uploads a .txt, .docx or .doc file to the server. Currently the model handles those files, saves some metadata (the extention and orig filename) then saves the file to the hard drive. Next it converts the doc and docx files to plain text and saves the output to a txt file. My problem is I want to copy the plain text contents of

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

We''re migrating a Rails 2.3.x application to Rails 3 and RSpec 2.x. In Rails 2.3.x we were using https://github.com/freelancing-god/after_commit to provide after_commit functionality (now provided by Rails 3). The plugin version of after_commit came with some helpers to make testing with `use_transactional_fixtures = true` work. From: https://github.com/freelancing-god/after_commit

Hi All, Is there a way to filter / modify the output of a model class before it''s returned to controller/view that''s calling it?

If I wanted to update an attribute with calling any validation or any of the before_save and after_save hooks, how would I go about doing this? Supposed the update_attribute method calls the before and after save methods. Thanks for your help. -- Posted via http://www.ruby-forum.com/.

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.

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/.

Hello! Sometime ago I ran across a webpage where someone had identified the full callback sequence for an object lifecycle including AASM with it''s :enter and :exit and whatnot callbacks. Unfortunately, I can''t find it and searches don''t seem to help. Does anyone have a reference to a page that shows the callback sequence with Acts As State Machine (the gem)? I think
