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:  
template\_of\_roster3: template\_of\_roster2  
template\_of\_roster4: template\_of\_roster3

controller:

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

and I use this hash in my selection like

view:

\<%  
templateOptions = “”  
@sites.each do |key,value|  
templateOptions = templateOptions + “#{value}”  
end  
%\>  
\<%=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.

I think you have to do something like this

\<%  
templateOptions = “”  
@sites.sort {|key,value| value[1]\<=\>key[1]}.each do |  
v|  
templateOptions = templateOptions + “#{v[1]}”  
end  
%\>  
\<%=select\_tag “templates”, templateOptions,{‘style’ =\>  
‘width:100px’ } %\>

try it out
