best way to add "created_by" entries to all tables???
Hi,
I want to automate somewhat the addition of created_by/updated_by fields
on my models (i.e. to include username). What''s the best/recommended
way to do this? Would it be to:
a) Find out how to extend the ActiveRecord::Base itself (I haven''t
extended a class before yet)
b) Use a plugin type approach where you have to add a tag manually to
each model file which then

help me understand association attributes
I have a model with a belongs_to association. The first model is called
Thing and the associated model is User. I''m attempting to assign the user to
the thing.
To accomplish this I used a before_save method, like this:
class Thing < ActiveRecord::Base
belongs_to :created_by, :class_name => "User", :foreign_key =>
"created_by_user_id"

How to write manage created_on and created_by via mixin?
Hi!
Definite newbie here - I''m working through this like-hate relationship with
Ruby and Rails right now... sometimes things work really well (like blobs
seem to rock) but other times, I dunno! :-)
Anyway, I''d like put in create and update user timestamps on all my primary
domain tables and allow them to be updated automatically by ActiveRecord.

this can only happen if a valid suberb is associated with it, and which
mechanisms of the below are supposed to do this?

before_create is after_validatation :on => :create , when it should be before_validation :on => :create
In ActiveRecord''s callbacks, methods within a before_create callback
are called after the validation, but before the model is created.
This was an intentional design decision, but I think it was the wrong
one. What do you think?
When I think of before_create, I think of before_validation :foo, :on
=> :create, but, by default, before_create is synonymous with
after_validation :foo,

DB trigger vs before_create
Hello everyone,
I''m having trouble figuring out which approach is better.
I have the following tables: products, orders and line_items.
Every time an Order is placed, the quantity field in the products
table has to be updated for each LineItem in the Order. One option is
to use DB triggers which is not as portable as using before_create in
the Order model. But with before_create I cannot

before_create firing twice on a save - RC2
I have a unit test which fails using Rails 1.2RC2, because a method marked
by the before_create filter is firing twice when my ActiveRecord is saved.
Is a before_create filter supposed to cause multiple invocations? We have
assumed it is called once, and only once, when the object is created, in our
code (but we unit tested it to make certain).
This is one of three issues I have with my unit

before_create question
I have the following models: User, Registration, Event.
User has_many Registration, Event has_many Registration, and
Registration belongs_to User and Registration. So far, so good.
There''s a registration deadline on a Event though, a few days before
the Event occurs.
So, I have this:

before_create return value breaking object.save: rails bug?
I know that usually when people say ''i think i found a bug in
rails/ruby'' they''ve done something dumb. I''m wondering if this is the
case here, but this does seem like a genuine rails bug to me.
In my user model i have a few different before_create callbacks. In one
of them, if it happens to return false (just because the last statement

a problem with before_create and validations
I stumble across some strange problem.
I have a model with a virtual attribute file_contents that is a string.
The model has validates_format_of :file_contents, :on => create, :unless
=> no_contents? (The method that returns file_contents.nil?)
Then, I have a before_create callback, where I get my model''s title and
description by parsing file_contents, and do write_attribute for

Comparing polymorphic property to same object fails
I''ve got a polymorphic association on one table. I assign to it in the
controller.
This is handling invitations of users to tasks in a task management
application. If the user issuing the invitation is the user being
invited (ie the user assigned themselves to a task), I want to
activate the invitation immediately in the model.
The trouble is that this:
