active_record postgresql adapter problem
Instead of using numeric I created the field "unit_price" as PostgreSQL
type money. Now when I try and add a row I get the following. How do I
override AR default behaviour to cast numeric post data to money, or am
I forced to only support database types that active_record knows about?

validate unless, LoginGenerator difficulty
I apologize if this is a very simple question; I''ve searched the forums,
wiki, Google, and Agile Web Development with Rails to no avail.
Is there a way to put conditional validation in the model? For
instance, if I want to limit items a user can add unless the user is an
admin? My current code is:

Year cost optimisation
Hi,
I have a data file with all our purchases from last year,
it contains the unit price, count, and total dollars spend.
Now I'm looking for some way to "classify" all our purchases to find out
which purchases are the best ones to find cheaper alternatives.
for example: if we only buy 1 item of a product which costs 5 dollar, we
maybe can find a cheaper product of 4.5 dollar, but

validates_uniqueness_of: passing a method to :scope
I was wondering if anybody knows an easy way to pass a method name as
the scope option to a validates_uniqueness_of validation on a AR model?
For example, I have nested models a bit like:
class Survey
has_many :areas
end
class Area
belongs_to :survey
has_many :questions, :order => ''position''

Where to place a global function
Hi all,
I have a little function called format_price(price) that simply formats the
argument as a dollar sign, dollar amount, dot and penny amount. Then, in
a .rhtml file, I could do this:
<%= format_price(item.unit_price * item.quantity) %>
But where do I put the format_price() function definition? The app couldn''t
find it in app/controllers/application.rb. Where do I put it

validates_uniqueness_of and MySQL enum type
I tried to check validates_uniqueness_of for a MySql enum type column
with a scope given, like this:
validates_uniqueness_of :phone_type, :scope => :user_id

validates_uniqueness_of :title
so let''s say I have the :title "Title 1" already in the database with
the :category of "1"
then if i wanted to enter the :title "Title 1" in the database again BUT
