Newbie question: Populating a selection list with numbers

Rails
1

Hi,

What is a nice, easy, one-line method of populating a selection list
with numbers in rails?

So far I can populate an array with the numbers I want using a loop:

<% opts = []
26.times do |x|
opts << [x, x]
end
-%>

and then use the opts array for the options in the select helper.

But is there a better way?

Thanks for any suggestions,
Richard

i just learned this

<% opts = Array.new(26) {|x| [x,x]} %>

perhaps it could be used this way too? (not positive)

<%= select ‘talent’, ‘age’, Array.new(26) {|x| [x,x]} %>

hope this helps,
Oliver

Here’s how I do it. . .

<%= select_tag :choice, options_for_select(0…30, @params[:choice]) %>

Thanks Oliver, that worked a treat!

(Using the method inside the select-tag helper function)

It’s probably still not quite what you’re after, but you can shorten
your code to:

 (1..26).collect {|x| [x, x] }

and put that directly inside the call to select.
