confirming that a model instance was correctly created from POST params
I''m wondering whether I''m wasting my time trying to verify that an addition I''ve made to legacy code is in fact setting a new attribute on a model.
Substruct''s (http://dev.subimage.com/projects/substruct) OrderHelper contains this method:
1 def create_order_from_post
2 @use_separate_shipping_address = params[:use_separate_shipping_address]

Aggregating two objects of the same type
I would like to have a customer that has references to two addresses,
a billing address and a shipping address. In a non-rails environment
I would have two keys in the customers table, billing_address_id and
shipping_address_id to reference the addresses. It appears that
ActiveRecord expects the parent id to reside in the child table,
regardless of whether the relationship is one-to-one or

one-to-one relationship confusion
Hello,
I posted a similar email, earlier in the week, but I still must not be
getting it.
I have a customer that aggregates two addresses; a shipping address
and a billing address. Addresses can also be referenced by other
objects in a similar way, so I would really like to avoid putting the
keys referencing the customer or other objects in the addresses table.
Addresses are exclusively

Please Help with single table inheritance relationships
I''ve been searching the web, wikis, and more, and I haven''t turned up
examples of how to have multiple entities in a single-table inheritance
related to anything.
I have an addresses table, but multiple entities can have Addresses:
both Person (which has 2 addresses) and Retailer. I''ve been told that I
need to use single-table inheritance, and this was my attempt:

Should controllers be "smart"?
I''m working on a small project with a friend, and one of the things we
needed to do was send off an email whenever someone signs up an
account. His implementation was pretty simple - throw a
deliver_welcome call inside the controller after the signup. I''m sure
that this is a pretty common thing to do.
The problem, in my mind, was that the app now became tied to two

Does mock_model''s :null_object option work?
Please understand in the following that I am making relatively minor changes to legacy (non-TDD/BDD) code in Substruct and don''t have the time to refactor nicely right now. I''m just trying to get past the untested/un-speced cruft quickly to write the spec for my new code, so I''m looking for expediency over prettiness.

Am I wrong or is fields_for not working right in Rails 2.2.2
I may be totally wrong about what the fields_for method is supposed to
do, but for some reason I thought using it scoped an object around an
association.
For example, I have a User class and when you''re creating a new user I
want to use fields_for to add a BillingAddress to the user like so:
<%- fields_for :billing_address do |billing_address_form| -%>
<%= render :partial

save without commit ?
How do I get ''save'' to execute without commit?
I have tried:
ActiveRecord::Base.connection.begin_db_transaction
# do some stuff that doesn''t issue a database COMMIT statement
# then:
@myObject.save
# this issues a COMMIT but it shouldn''t! Shouldn''t it wait until I''ve
called:

dynamic setting of username and password in database.yml
Hello
I''ve now read a lot about application-level authentication in Rails, but
I need to do database-level authentication.
The reason is that my database needs to have the current_user (database
current_user, not current_user defined in an ActiveRecord Model) set to
execute triggers for automatically updating audit tables. So it is not
enough to have a session check against a User

composed_of, aggregate object isn't saved
I am relatively new to rails and I cannot figure out what is going on
here. I am using the composed_of method in an ActiveRecord class to
create two aggregate properties: shipping_address and billing_address.
The object properties are getting populated from the form and validation
is working - no problem. When I call order.save, though, everything is
being saved except the address fields. I am not

Namespace & Organisation Conventions
Hi All
I wanted a little advice on the convention for namespace usage and
organisation of code.
I originally used PHP and often had an "admin" backend that performed the
various admin tasks with users, and data
Then I had a front-end often situated at the root that had user services.
I''m trying to emulate this in Rails but feel I''m missing a significant point

ActiveRecord in Rails 2.1.0 misbehaving for Aggregate Attr.
I am not sure if this is a bug in ActiveRecord or is this the intended
behavior. If it is then it does not make sense to me.
In a nutshell: If you change an aggregate object attribute created via
composed_of method (see Agile Web Development - Second Edition Chapter
17 page 313 onwards) and then save the model, the change to the model
(composite attribute specifically) will not be saved UNLESS

autosave no longer a valid option for belongs_to?
The Rails API doc (api.rubyonrails.org) says that :autosave is still a
valid option for belongs_to in the latest version of Rails. However, a
look at the activerecord/lib/active_record/associations.rb (line 1590)
reveals that it is not in the @@valid_keys_for_belongs_to_association
array. I also noticed that it''s not in the ActiveRecord API doc
(ar.rubyonrails.org).
