Hello RoR Developers,

I have tiny problem with sorting hash. I can not sort hash values.

i have hash which is created by yaml file. yaml file

template1: &nbsp;&nbsp;template\_of\_roster3: template\_of\_roster2 &nbsp;&nbsp;template\_of\_roster4: template\_of\_roster3

controller:

@get\_config=YAML.load(File.open("#{PATH\_IM}/.......yml")) &nbsp;&nbsp;&nbsp;&nbsp;@get\_config == Hash &nbsp;&nbsp;&nbsp;&nbsp;@enterprises==Hash @my\_hash=@get\_config["template1"]

and I use this hash in my selection like

view:

\<% &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;templateOptions = "" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@sites.each do |key,value| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;templateOptions = templateOptions + "\<option value=#{key}\>#{value}\</option\>" &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;%\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<%=select\_tag "templates", templateOptions,{'style' =\> 'width:100px' } %\>

in fact there is no problem here but when I update my hash like this @new\_hash={"new\_hash"=\>"new\_hash"} @my\_hash.update(@new\_hash)

it s sorted like, new\_hash template\_of\_roster2 template\_of\_roster3

but I want to see new\_hash at the last option. how can I do it? any idea.

thanks

By not using a hash. A hash just isn't ordered in ruby (in 1.9 they  
are ordered by the order of insertion). ActiveSupport also provides an  
OrderedHash class.
