simple association question
I have two models, Donor and Contribution, and have has_many and
belongs_to set respectively.
My question is regarding creation of associated objects. I''ll let the
code speak:
me = Donor.find(1)
contribution = me.contributions.create do |e|
e.amount = 164.00
e.category = Category.find(1)
end
I thought this was valid, but it doesn''t work properly - it appears to

Can I tell if the associated record is new in a belongs_to save?
In a belongs_to association, is there a way to tell if the associated object
was newly created?
Hopefully this will explain my question:

Should counter_cache fields be saved in the database?
As far as I can tell, the counter_cache option on a belongs_to model
doesn''t actually save anything in the database. For example, I have
the following models:
class Parent < ActiveRecord::Base
has_many :children,
:conditions => "deleted_at IS NULL"
end
class Child < ActiveRecord::Base
belongs_to :parent, :counter_cache => true
end

Validation errors in has_one/belongs_to relationships.
I have two objects, QuoteInput and Insured.
QuoteInput has one Insured and Insured belongs to QuoteInput.
I don''t understand what I''m seeing.
I assign an Insured to a QuoteInput. The Insured object has invalid
data.
I call save! on the quote input. QuoteInput has no validations.
I expect two things to happen - 1) an exception should be thrown,

spec a replace_html with a partial
I wanted to use ARTS to add RJS in a behaviour driven way to my
application, but I''m having some trouble asserting a replace_html with
a partial.
I''ve created a pastie (http://pastie.caboo.se/60694) which contains
the RJS I want to spec, the spec which I already wrote and its failure
message.
I''m currently using RSpec-0.9.2

Setter that converts a float attribute to integer
Hi,
I have some problems with an application where I''m using custom
accessors to do currency conversions. In my model, I have a price
attribute in the database that stores the value in cents, to avoid
future problems with float arithmetic and round. But at the views, I
would like to show the price in euros, with decimal for the cents. So
I defined a new attribute called price_in_euros,

Save using Update
Hi,
I want to update an existing row in table "items" where items.id == 10
I tried this:
item = Item.new
item.f1 = ...
item.f2 = ...
...
item.id = 10
item.save
I got an error
Duplicate entry ... for key 10 : INSERT INTO items ...
How do I make item.save to use UPDATE instead of INSERT?

How to determine if an object has just been created
Is there a built-in way to determine if a model object has just been
created (ie. this object was the one that was originally persisted)? I
can''t see it anywhere in the AR code, but thought I''d check. I want
something like:
p = Person.create
p.original_instance? # true
Is this built-in or should I just patch AR?

update or alter cart
I want to modify and update the items in the Depot - "display_cart".
Since the cart is in a session, its a little hard to get at the data.
I just want to create a way to change quantities, prices and
recalculate.
Has someone done this, and could you point me to the right direction.
Thanks
