Rails - Apr 2006 - select_tag - populating options

Hello,

I want to a select tag, where you can choose a number between 1 and 100.

My inital code is based on the examples from Agile Web Development with 
Rails, and looks like this:

view:
<%= options = [["Select number of lines", ""]] +
RfqLines::LINE_QTY
select("rfq_line", "line_qty", options) %>

model:
    LINE_QTY = select_fill

    def self.select_fill
        @filler = []
        1.upto(100) do |count|
            @filler << count
        end
    end


Obviously it is not working, and I''m sure there is some easy way of 
doing it..

Many thanks in advance,

/mich

this works:

<%= select("rfq_line", "line_qty", @options) %>

don''t forget the ''@''

Hmm, it still does not work - I am seeing the following error:

undefined local variable or method `select_fill'' for RfqLines:Class

this will definitely work:

<%= select("person", "name", %w{Peter Paul Mary}) %>

the error should come from other parts of your code

Yes, I am aware that it would work - but initial question was regarding 
auto population of the options, so I do not have to write:

%w{ 1 2 3 4 5 6 7 ...... 100}

%w{a b c} can be easily replaced with an instance variable @options.

Why not like this:

model:
LINE_QTY = (1..100).to_a
