Money library usage?
Hi,
I''m obviously doing something stupid, but I''m trying to figure out how
the Money library (http://dist.leetsoft.com/api/money/) is supposed to
work. I have a Product model and I want to have an attribute in my
model called "price" and I want it to accept Money objects.
So I have this in my Product model.
class Product < ActiveRecord::Base

How to use validation with aggregation (composed_of)?
At the risk of being banned for posting the same question twice, I
thought I''d try once more with a question for the title rather than a
statement (on the basis that perhaps questions get answered and
statements ignored ;-) )
ActiveRecord supports composed_of for value objects which is
fantastic but one thing that it doesn''t seem to support (or at least

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

Incorrect composed_of I think
I am trying to use composed_of in my model, but I not succeeding.
With the code I pasted below, I cannot perform this action in the console:
property = Property.new(1, "px")
I get NameError: uninitialized constant Property when I try to perform
that action. It''s not finding my class I made I suppose. The Property
class is in the same file as the Element class, element.rb.

I''m using composed_of in one of my models, and I''d like to validate

unused composed_of bits
I implemented a Temperature model for my application. It is pretty basic,
composed of a temperature, a unit and some conversion methods. In my app model
I decided to store temperature values in Fahrenheit, so there is no need to
remember the units between invocations. I am having a little trouble composing
my app model.
A little bit of my temperature class:

Aggregation: problem with uninitialized composed_of object
Hi,
I''m getting this error:
>> p = Plan.new

TypeError: wrong argument type String (expected Fixnum)
Apparently this happens because the aggregation isn''t initialized.
Here''s the code:

Authentication design/ideas
Hi all,
I''m using acts_as_authenticated for the front end facing part of my
site. I have a model called Customer. I now want to protect the admin

Store/product stock design question
Hi all,
I''m having trouble figuring out how to handle stock levels in a new
store I''m building. When products are entered into the admin of the
store, they have a stock number associated with them.
What I''m not sure about, is how I go about maintaining this stock
level. Take this scenario:

TimeZone, TZInfo, daylight savings, and composed_of
Does anyone know the best way to track time zone information. There doesn''t
seem to be much documentation on this. So far it seems like a simple db
field like
create table accounts (
id int unsigned not null auto_increment,
name varchar(50) not null,
time_zone varchar(50) not null,
...
primary key (id)
)
and a class like

I am using file_column for some image uploading. I want to have all
the images stored under one root which I have managed by setting the

So, my images get uploaded to:

Does Amazon.com blocks scraping?
Hi there
Does anyone know if Amazon.com has any sort of server side script that tries
to block scraping activities? I first noticed that if I didn?t change the
agent alias, it would fetch a page exactly like the normal one, but without
the intial search field(maybe a silly way to prevent scraping). Then after
it, I changed to some other alias, and submit a search. I got the result

Validating numericality based on related attribute value?
I have a price attribute in my model which I need to validate as a
positive number if the attribute price_terms.requires_value is equal to
''Y'', otherwise price can be blank or zero. Price_terms is a select list
which my model table belongs_to.
How do I do this? - I tried doing this:
