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 D. 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,

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

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

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}

def self.select_fill
@filler = []
1.upto(100) do |count|
@filler << count
end
end
Why not like this:
model:
LINE_QTY = (1…100).to_a
