Iterate through to create a hash of hashes

Question

As the final result I need a hash like:

{items: {lorem: val1, dolor: val2}, {lorem: val1, dolor: val2}...}

eg a hash of hashes.

Put the problem is it should be created from iteration like this:

@result = []

@goods = {lorem: "ipsum", dolor: "sit"}

@items.each do |item|
  @goods.map do |k, v|
    if item.title == "ipsum"
      @result << [k, v]
    else
      @result << [k, item.title]
    end
  end
end

But this is not what I'm searching for, as @result is Array, and it's not 2-dimensional (as result i have [[foo, bar] [foo1,bar1]...])

I see how k could be converted to Hash key (k.to_sym), but my problem is to have Hash of hashes as the final output.

Ruby 1.9.3 (and Rails, but I believe this could be done without any Rails additions)

Many thanks.

Answer 1

The format of the expected result is not a valid Hash.

Instead of

{items: {lorem: val1, dolor: val2}, {lorem: val1, dolor: val2}...}

It should be like this

{items: [{lorem: val1, dolor: val2}, {lorem: val1, dolor: val2}]}

It's also not hard to get the result you want

@items = []
@goods = {lorem: "ipsum", dolor: "sit"}
@items << @goods
@result = {items: @items}
