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,

/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

%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}

Why not like this:

model:  
LINE\_QTY = (1…100).to\_a
