@make_num = (1..50).entries

something like?

<%= f.collection_select(:make_num, @make_num.collect {|c| [c, c]}) %>

i get wrong number of arguments (2 for 4)

thanks!

<%= f.select “make_num”, 1…50 %>

great thanks!! sometimes things are just too easy.

I think that'd be something like:

  <%= f.select(:level, 1..200, {:prompt=> "N/A"}) %>

(Not sure if those curly braces are necessary, but they shouldn't hurt...)

Hmmm--that's different I think. With :prompt, the string you give isn't actually stored in the db--it'll get translated to a null. You can use the very same call in your edit view, and again nulls should be translated into the prompt value. But if you really want to store "N/A" in the db, you'll have to do something like:

# In your model, say: class MyModel < ActiveRecord::Base   ALLOWABLE_LEVELS = (1..200).to_a << "N/A" end

# and then: <%= f.select(:level, MyModel::ALLOWABLE_LEVELS) %>

Mind you, your level field will have to accept strings if you do this...

HTH,

thanks again roy that helps. the only thing is that edit shows the prompt N/A only if the value is already null.

if i set the level to 3 and then edit. there is no more N/A to chose from.

but yea i would want the value to be stored as NULL when selecting N/A.
