Rails mapping array of hashes onto single hash

Question

I have an array of hashes like so:

 [{\"testPARAM1\"=>\"testVAL1\"}, {\"testPARAM2\"=>\"testVAL2\"}]

And I\'m trying to map this onto sin

Answer 1

Use #inject

hashes = [{"testPARAM1"=>"testVAL1"}, {"testPARAM2"=>"testVAL2"}]
merged = hashes.inject({}) { |aggregate, hash| aggregate.merge hash }
merged # => {"testPARAM1"=>"testVAL1", "testPARAM2"=>"testVAL2"}
