Rails and Service Oriented Architecture (SOA): any downsides?
Hey folks,
I like what I''m reading about improved performance via Service
Oriented Architecture for my Rails app. Stepping in that direction
will require some code reorganization, though. Has anyone regretted
the time invested in Rails SOA or suffered any other drawbacks that
might -- from a business perspective -- have disinclined them from
going SOA?

what is a session stored via the active_record_store option unique to?
Hi,
After a bunch of snooping in AWDWR and Railsguides I can''t reach a
good understanding to the following question: What is a session stored
via the active_record_store option unique to? In other words, how does
rails bind the user to their session under the active_record_store
option?
This concern has arisen in the following way...

Unknown column 'quotes.organisation_id' in 'where clause': SELECT * FROM `quotes` WHERE (`quotes`.organisation_id = 1036)
Hi,
I have a small app that needs to keep track of quotes, and
organisations. An organisation can either be the unit who finally
receives the goods (the end_user) or and intermediary (customer) (and in
some cases both)
An Organisation will (hopefully :) ) have many quotes; and a quote
can belong to an organisation, either as a customer or as an end_user or
both.
So the quotes table

Deep nested associations on the same Model
This could be a lot simpler than I think and I''m just missing something
obvious!
I''m working on a creative collaboration app whereby one user could
submit a Story and this can then be forked by another user and worked on
seperately. To acheive this I have a has_many association within the
same Story model as such:

tips on how to write a controller test for models associated with currently logged in user
I have a controller test here:
http://gist.github.com/275616, which works fine when account is an
independent model, however I want:
an account to be a property of user, ( and created and associated when
a user is)
when the user goes to /account/edit it should on edit the account of
the logged in user -
I can make rails do this, but I''m utterly baffled how I should alter

Altering the accessor of an association collection
I want to be able to do something like this (for example):
class Person < ActiveRecord::Base
has_many :friends
def friends(living_in = :uk)
# filter based on parameters here
end
end
Is there any way I can redefine the accessor for an association whilst
still being able to get the values? Basically, I''m looking for an
equivilent of read_attribute() for associations.

Advice on data design idea
I''m about to embark on a project and am seeking advice on my approach.

checked out different nested set, ancestral, acts_as_tree, acyclic
plugins but feel they don''t exactly fit.
So I am about to roll my own simple solution. Any feedback as to
whether this looks good is appreciated.

Join Tables
I just have a few questions about join tables. From my understanding
the following applies (correct me if I''m wrong):
1.Join tables are always named with the names of the two associated
tables, in alphabetical order, separated by an underscore.
2.The foreign key fields are named with the name of the table they are
referencing, with _id appended.
3.The foreign key is referencing a

validates_uniqueness_of across multiple rows?
Ok, that''s not the best subject line, but I couldn''t think of a
concise way to describe what I''m trying to do.
I''ve got two models. Grouping simply contains an id and a few other
attributes (e.g. rating). A grouping can contain many elements which
are stored the Element model.
A set of elements is tied together by a grouping_id. An element can

I''d like to make a demo version of my app available, but I''m not ready

validating both sides of a has_one relationship breaks pickle/machinist tests
A lot has been posted about validation issues with associations,
however, I don''t see this issue addressed specifically.
ex:
class Foo
has_one :schedule, :dependent => :destroy
validates_presence_of :schedule
class Schedule
belongs_to :foo
validates_presence_of :foo_id
this creates a circular dependency that breaks test frameworks like
pickle and machinist.

database design question: building features
I am trying to decide between two different database architectures for
