Question

In Ruby, I need to convert a string like this:

"keyA,valueA,keyB,valueB"

into a hash like this:

{"keyA"=>"valueA", "keyB"=>"valueB"}

I’m pretty sure this will involve the each_slice method and possibly the enumerable inject(), as described in “ruby string to hash conversion“.

but I have no idea how to bring these components together.

Answer 1

s = 'keyA,valueA,keyB,valueB'

Hash[*s.split(',')]
#=> { 'keyA' => 'valueA', 'keyB' => 'valueB' }
