You are mixing up arrays and hashes. Below is an all hash example.
@prices = {
"amazon_new" => {
"image" => "imageurl.com",
"url" => "bookurl.com",
"price" => 45.55
},
"amazon_used" => {
"image" => "2ndImageUrl.com",
"url" => "2ndbookurl.com",
"price" => 67.45
}
}
@prices.each_pair do |type, data|
puts "#{type} : #{data[''image'']}"
end
and here is an array / hash example
@prices = [
{
"image" => "imageurl.com",
"url" => "bookurl.com",
"price" => 45.55
},
{
"image" => "2ndImageUrl.com",
"url" => "2ndbookurl.com",
"price" => 67.45
}
]
@prices.each do |data|
puts data[''image'']
end
