Drop down list ?
Hi Gurus, I''m trying to tackle a drop down list. I have category and
item dbs, and they''re wired up with category has_many :items and item
belongs_to :category, and an item has a category_id. I have this code
in my new/edit.html.erb for item:
<%= f.collection_select :category_id,
Category.find_main, :id, :header, {}, :multiple => false %>
And a pretty drop down list

number_to_currency not working since 2.1.1
Back in 2.1.1 everything was sweet:
Loading development environment (Rails 2.3.3)
>> include ActionView::Helpers::NumberHelper
=> Object
>> number_to_currency(12.3)
>> "$12.30"
Then I upgraded to 2.3.2 and:
Loading development environment (Rails 2.3.3)
>> include ActionView::Helpers::NumberHelper
=> Object
>> number_to_currency(12.3)
>> 12.3

number_to_currency inside model
I was wondering if this is possible.
I have a model (Item) that contains products. These products have prices
that I''d like to format using number_to_currency. Rather than doing this
several times inside the view, I thought it might be nice to do it once
inside the model.
The item table has an field called regular_price which holds a currency
amount. I would like to do something

Cannot use view helpers in RJS helpers
Any ideas why I would get an error in a RJS helper on view helpers
such as number_to_currency.
Example:
# my_template.rjs
page.help_me
# my_helper for my_controller
def help_me
number_to_currency(10)
end
I have also tired page.number_to_currency but that doesn''t work either.
Cheers,

bryce benton wrote:
> number_to_currency(1234567890.506) => $1,234,567,890.51
BTW agile book does mention this ..
will this number_to_currency(x) be internationalized ? or i can set it
to Indonesian for example (or to any other languages rather than just
English) ?

uniqueness validation perplexity
I want to write a validate routine to check to enforce that a position
must be unique in a category. (In another category, it doesn''t have
to and shouldn''t need to be unique.) I write this code which works
happily for new items:
def position_in_category_not_unique
@items = Item.find( :all, :conditions => [ "category_id = ? AND

Doubt with symbols in Rails
I was trying to write a wrapper for number_to_currency to return
currency in pounds. I used a helper class to do this.
def number_to_pounds(amt)
number_to_currency(amt, :unit => "£")
end
This works fine, but I am trying to understand why I can''t use a
symbol to pass the values. I thought symbols were like pointers. (you
now know I am a newbie).

number_to_currency() helper == non DRY == could be improved
Hi all,
Apologies in advance if I got this one wrong, I''m still just a
newbie ;-)
Going through the Apple ADC RoR tutorial it suddenly occurred to me
that the ''number_to_currency()'' helper method was not DRY streamlined.
Scenario::
The "number_to_currency()" methods options hash works great when I
need to dynamically display different currencies when I

I''m trying to use number_to_currency in one of my models, but i''m
getting the
following error:

Formatting Data in rhtml
Is there a simple way to format your data in the .rhtml file?
I come from a PHP/Smarty background, and in the templates, I''ve used
what is called "modifiers" to format data.
{$price|currency_format} # displays in currency format
{$description|truncate:"100"} # Truncates the description after 100
characters
It seems like the template (rhtml) would be the ideal
