What is the best way to create a drop down where there is no backend
model to get the values from?
I am currently using:
<%= f.select(:year_made, ((1980..Time.now.year).collect {|p| [ p, p
]}).reverse, {:prompt=>"Select a Year"}) %>
but this gives me issues when I am trying to edit the info as the
currently saved value from the database is lost when edit action is
called.

Man i always post my questions wrong, My dropdown will contain date range from 1980 to current year where as the db will only contain the saved years say 2000. -- Posted via http://www.ruby-forum.com/.

Well with this code,
<%= f.select(:year_made, ((1980..Time.now.year).collect {|p| [ p, p
]}).reverse, {:prompt=>"Select a Year"}) %>
it does not seem to work and that makes me wonder what is wrong with
this code?

What does generated html of the select look like? (View, Page Source or similar in your browser) Have you checked that year_made contains the previous value. Possibly put <%= @object.year_made %> in the form to check. Colin

I wonder whether it is expecting an integer as all my uses have always been with an id value. Any other ideas anyone? Colin
Well it turns out that it was a string vs integer issue. I have my
fields in db as string and the code was generating a integer so that
caused issues at edit time.
I made the following change and now it seems to work.
<%= f.select(:year_made, ((1980..Time.now.year).collect {|p| [ p.to_s,
p.to_s ]}).reverse, {:prompt=>"Select a Year"}) %>
Does anyone else have a better idea on how to do this?

No. This is the right way to do it. Data type matches are necessary for functionality, you can''t ignore those.

Presumably it would also work if, instead, the type of year_made were changed to integer. Arguably this might be a more aesthetically pleasing solution.

I agree with you on that. And will think about converting to integer, I do have two more drop downs with similar values but they do have one or more string values so they do require to be strings but the year_made does not. -- Posted via http://www.ruby-forum.com/.
Back again with another question.
For the drop down below
<%= f.select(:year_imported, ((1980..Time.now.year).collect {|p| [
p.to_s, p.to_s ]}).reverse, :prompt=>"Select a Year") %>
I also want this to contain a value, "Local" as the first one in the
list. What is the best way to do this?

Hi,
What essentially you are doing here is creating an array. So you can prepend
"Local" in the array like this
((1980..Time.now.year).collect {|p| [p.to_s, p.to_s ]}).reverse.unshift
"Local"
I will also suggest you move out this array creation, and put it as a helper
method.
