Get all hash in array, ruby on rails

Question

Can I get all hash in array like this:

a = [[[{id => "1", com => "abcd"}],[{id => "2", com => "rty"},{id => "3", com => "mnq"},...]], "products"]

I want to get hash only like this :

b = [{id => "1", com => "abcd"},{id => "2", com => "rty"},{id => "3", com => "mnq"},...]

Please! tell me how to do that in ruby on rails :)

For this you can use the #flatten or #flatten! methods found for Array's in Ruby

So just use

a.flatten

and the result will be what is shown in b

As the last element of a is not a hash, it appears you need an additional step: a.flatten.select { |obj| obj.is_a? Hash }.
