Issue with Observers and has_one association...
Hey Guys,
I''m getting a peculiar bug working with Observers and has_one
associations. When a has_one association is invoked by an Observer it
always returns null. I looked in the development.log file and the SQL
for the has_one association isn''t even being executed. On the other
hand, when I replace the has_one association with just a hand crafted
method, it does get called

saving a has_one association question
Hiall,
Say I have
class User
has_one :community
end
class Community
belongs_to :user
end
Will the following work and both save user and community if validation
doesn''t fail?

Or do I have to do something like the following

if user.save
user.community = params[:community]

optional has_one association
Hi!
I have a has_one association which is used for extending an entity,
like:
class User < ActiveRecord::Base
has_one :user_ex
#name, email
end
class UserEx < ...
#country, city, street...
end
The UserEx entity is optional (there are users without extended info).
My problem is: if u is a User object which has no user_ex extension,
activerecord always tries to fetch the UserEx

after_create and has_one association bug?
Hello,
I''ve come across an issue that I''m sure is a bug when using after_create
with a has_one association, but I''m not 100% certain if I''m missing
something.
This is pretty much exactly the code I''m using. Two simple classes
(Account and Contact) and I create the contact after I create an account
(via after_create). I''m not passing in a

Help: A copy of ModelSecurity has been removed from the module tree but is still active!
Hi all, I''m posting this in the hope that someone who understands
rails dependencies can shed some light.
I''ve implemented a "ModelSecurity" module in the vein of Bruce Peren''s
old ModelSecurity plugin (http://rubyforge.org/projects/model-
security/).
My ModelSecurity module lives in $RAILS_ROOT/lib. It is automatically
included into ActiveRecord::Base by a

ModelSecurity for Rails by Bruce Perens
Modelsecurity aims to provide access control within the data model so
that it becomes easy & efficient to specify read or write access to
individual fields.
It has one of those "why didn''t I think of that?" designs which make a
lot of sense.
Has anyone else tried using the latest release of ModelSecurity? What
has been your experience?

Rails doesn't validate create_model or build_model (has_one association)

Experiences with ModelSecurity

plugin by Bruce Perens.

list however, I didn''t read much about it. Apart from it''s security

Anything but Aptana
Not trying to get into a "What''s a good IDE" here, BUT....On
Windows....RadRails never cut it. Under Aptana, it''s a terrible joke,
and I''m sick of losing so much time waiting not only for this thing to
initialize, but the hanging and crashing I go through is killing me.
Please, someone....point me to a decent, lightweight IDE. All i want
is syntax coloring.

can I fake has_one :through?
I''m having a difficult time wrapping my head around a set of models
and their associations and seeing how they map into Rails. I''ll try
to lay out my problem using the has_many and belongs_to structures. I
have a RuleSpace, a Rule, and a Subject.
A RuleSpace has_many Rules
A RulesSpace has_many Subjects through Rules
A Rule belongs_to (many) RuleSpaces

building and saving has_many and has_one relations
Hi,
I am very confused about an aspect of has_one and has_many relations,
with regard to using the build method, and saving the belongs_to side.
It''s a somewhat long post. so please bear with me :)
First let''s consider the has_one scenario. Let''s say I have a student
who must own exactly one car:
class Student
has_one(:car)
end
class Car
belongs_to(:student)
