Answer 1

As per the clarification in the comments, I will also answer. My solution is much the same as Зелёный's, but it takes dynamic attribute setting into account

mashie.products.each do |product|
  product.extend Hashie::Extensions::DeepFetch

  i%[name sale_price currency].each do |attribute|
    value = product.deep_fetch attribute { 'not found' }
    product.send("#{attribute}=", value)
  end

  @products << product
end

Answer 2

I not sure about right syntax in product.price = product.deep_fetch(attribute, { 'not found' }):

mashie.products.each do |product|
  product.extend Hashie::Extensions::DeepFetch

  i%[name sale_price currency].each do |attribute|
    product.price = product.deep_fetch attribute { 'not found' }
  end

  @products << product
end
