hi,
i''m trying to add a select box with the select method, but rails orders
it according to the name, while i needed ordered according to the value,
or just to work in the order i put it in.
this is my array:
@price_range = {"$100-$200" => "0", "$200-$300"
=> "1", "$300-$350" =>
"2", "$350-$500" => "3"}
and this is my view:
<% fields_for(@description) do |d| -%>
<%= d.select( :price_range, @price_range ) %>
<%end$>
i can''t figure out how to do this, it subtracts one number from the
other number (100 from 200) and then orders from lowest to highest,
which is not what I want.
any help is greatly appreciated,
thanks

It''s a hash, and hashes are unordered - or at the very least you can never rely on its ordering. Try this instead: <%= d.select(:price_range, @price_range.sort) %> Hope that works. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
