Calling hashes from another hash

Rails
1

I am trying to get this going where i have this build array and then I
have an array of hashes named after the items in the build. Depending
upon what is in the array, I want to read the arrays of hashes. I
wrote
this simple script, but does not work. Any solns
build = [ "log " ,
“top” ]

log = [

 { 'where'                    =>  '/home/des/blocks/where.rb'},
 { 'when'                     =>  '/home/des/blocks/when.rb'},
 { 'bank'                     =>  '/home/des/blocks/bank.rb'}

]
top = [

 { 'where'                    =>  '/home/top/blocks/where.rb'},
 { 'when'                     =>  '/home/top/blocks/when.rb'},
 { 'bank'                     =>  '/home/top/blocks/bank.rb'}

]

build.each{ |bu|
puts bu
bu.each{ |files|
puts files

}}

So you want to iterate over the build array and then do something with
the local variable named by the items in that array. There’s not
really a nice way of doing that - I would reorganise your data (eg why
have two local variables log and top rather than a hash with keys log
and top ?

Try:

build.each do |pu|
eval(bu).each do |files|
…
end
end
