similar to: Something as after_successful_validation?

Le''s say that I have a table called people and the column middle_name is nullable. If the user enters say blank or empty space then in the database it is recorded as empty space. I would like in all my models all empty spaces to be recorded as null. I guess I can write a plugin which will do so for all the models but I''m sure something like that should already be existing.I

Hello ! I posted a simple template to show how to add ''act_as_whatever'' to ActiveRecord. I think this might be useful to others as there are some trickery ruby things in this file. Here is the template : http://textsnippets.com/posts/show/384 Gaspard Bucher -- Posted via http://www.ruby-forum.com/.

Hi plugin-authors. So this is a little bit of take two on this question, but why can''t I access a singleton on the model calling my plugin? The crux of the full plugin below is: #logger.info self.class.to_s new_copy = self.class.new( @copyable_attributes ) the logger spits out "Datatype", but I get an error from rails saying: undefined method `datatype'' for

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`,

Quick question: Given a basic plugin... how can I access an object that I instantiated in the acts_as method from an instance method? Probably some sort of accessor... but where? def self.included(base) base.extend ClassMethods end module ClassMethods def acts_as_test object = Object.new ## This object needs to be accessible from the Instance Methods end include

Hi, Just wondering when one would use "include" over "extend"? Both seem to bring in methods to the class no? The context is I''m just trying to understand why both are used with the acts_as_audited plugin: Full extract from plugin (used within here): ================================================== # Copyright (c) 2006 Brandon Keepers # # Permission is hereby

I''m using Restful Authentication, and the code to create a user is pretty straight forward - there is a before_save action and a before_create action: before_save :encrypt_password before_create :make_activation_code But for some reason when I try to create a user programmatically in the controller like this: User.new(:email =>

I am having a problem finding the best way to make a "before_save :encrypt_password" conditional. I have to at times update user model attributes but each time I do this the password is reencrypted because of the above. I need to differentiate between when the user is first logging in and the password does need to be encrypted, and when they are already logged in and the

Hi. I have to convert the contents of all columns to uppercase before creating a row. Is there an easy way to accomplish this so I don''t have to go one column at a time and upcase! it? Thanks.

Is there a way to get the MIME extension of a file_column field? Here''s what I want to do (look for comment in before_save method): class ProductFile < ActiveRecord::Base belongs_to :product file_column :file_name def before_save self.file_type = # something that returns the MIME type (e.g. image/jpeg) end end TIA

So I have a database of orders more or less.(it is currently in the process of being upgraded to mysql with a rails fronted, from OLD Paradox database) On one page I made a ''create new order'' system. This allows me to put in the due date and other info. However I wanted to put in the default value of ''0000-00-00'' for the shipped date, as it hasn''t

Hi all, I have a multi model form (Project with many tasks) and I want to prevent a task from being saved to the DB if it is empty ie. if there is no i/p for that task from the user. I tried the following class Task < ActiveRecord::Base before_save :check_if_empty ... def check_if_empty self.destroy if description.blank? end but i get this TypeError in ProjectsController#create

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

Is it will known and accepted that before_save triggers should return true? I didn''t notice this before but now I see it in the documentation. Here is what I''m doing in my model: def before_save if self.has_album? self.visible = self.album.visible? end end That results in the expected result when album.visible? is true - but not when it is false. To make it

Hello there, I''m currently building a plugin, for which I need a before_save callback. The method I want to call is in module InstanceMethods, but when I add a before_save foo, foo, as defined as an InstanceMethod, never gets called. This is the first plugin I''m building, after only two weeks of fiddling with Ruby and Rails, so if anyone is kind enough to help me out.... :)

I am trying to write a plugin, ''acts_as_commentable'', for my models - Image, Book, Music and so on, I do not want to use polymorphic association, so very model should have its own comment class. Here is my code acts_as_commentable.rb module Commentable def self.included(base) base.extend(ClassMethods) end module ClassMethods def

We all know that acts_as_tree gives us ability to set up data in a tree-like structure and use methods like ''parent'', ''children'' and so on. Something I''m completely stuck on. Observe. class Page < ActiveRecord::Base acts_as_tree def before_save raise self.parent.to_yaml end end Well, you''d think that it should show

Greetings, This, I hope, is a simply answered question. Based on Agile Web Development with Rails (depot application), I''m developing a single table application for contact info. There is only an admin side to this, so there''s always authentication. Part of the info record (member) is changed_by and changed_at which I automatically want updated. Changed_at looks after

I am sitting with the Agile book on my desk and scratching my head at the discussion on aggregation - perhaps that isn''t what I need. I have a db called clients. fields include - first_name middle_initial last_name I want to combine them all into one name element in a list view. I can add/edit the fields separately but in the list view, I only want the one combo field. Is there a
