Question

I am attempting to access hash data in sinatra:

require 'rubygems'
require 'sinatra'

class List 
   def self.items
   return items = {

   :something1 =>  { :attribute1 => "somestring1", :attribute2 => "somestring2" },
   :something2 =>  { :attribute1 => "somestring3", :attribute2 => "somestring4" }

   }
   end
end

list = List.items

get '/' do
   list.each do |name, meta|
      "#{name}<br>#{meta[:attribute1]}<br>#{meta[:attribute2]}<br><br>"
   end
end

I expected sinatra to print the hash data of each hash. However, it printed just the hashes instead (probably because I called list.each). The console prints the expected result when I use puts.

To clarify, the desired result is:

something1
somestring1
somestring2

something2
somestring3
somestring4

How do I make sinatra print just the variables?

Thanks!

Use map instead of each, and then join the result to return a string:

get '/' do
  list.map do |name, meta|
    "#{name}<br>#{meta[:attribute1]}<br>#{meta[:attribute2]}<br><br>"
  end.join
end

each returns the array you call it on. map will return a new array, transforming each entry in the Enumerable according to your block.
