Question

Is there a simple way of remapping a hash in ruby the following way:

from:

{:name => 'foo', :value => 'bar'} 

to:

{'foo' => 'bar'} 

Preferably in a way that makes it simple to do this operation while iterating over an array of this type of hashes:

from:

[{:name => 'foo', :value => 'bar'}, {:name => 'foo2', :value => 'bar2'}] 

to:

{'foo' => 'bar', 'foo2' => 'bar2'} 

Thanks.

Answer 1

arr = [ {:name=>'foo', :value=>'bar'}, {:name=>'foo2', :value=>'bar2'}]  result = {} arr.each{|x| result[x[:name]] = x[:value]}  # result is now {'foo2'=>'bar2', 'foo'=>'bar'}
