Ok so I am trying to read a hash of arrays and I seem to be getting a
cannot convert string to integer error. Here is my code:
<% @information[‘food’][‘servings’].each do |servings| %>
<% servings[‘serving’].each do |serving| %>
<%= serving[‘name’] %>
<% end %>
<% end %>
Here is what the hash looks like:
@parsed_response={“food”=>{“name”=>“Chicken: Breast Quarters,
rotisserie, no skin or wing (Boston Market)”,
“id”=>“42e5699f-79cd-436c-965b-90850b26a278”,
“servings”=>{“serving”=>[{“name”=>“serving (4.9 oz)”,
“nutrients”=>{“calcium”=>nil, “satfat”=>“1”, “fat”=>“4”, “carb”=>“2”,
“fiber”=>“0”, “sugar”=>“1”, “protein”=>“33”, “sodium”=>“480”,
“cholesterol”=>“85”, “calories”=>“170”}}, {“name”=>“oz”,
“nutrients”=>{“calcium”=>nil, “satfat”=>“0.2025”, “fat”=>“0.81”,
“carb”=>“0.405”, “fiber”=>“0”, “sugar”=>“0.2025”, “protein”=>“6.6825”,
“sodium”=>“97.2”, “cholesterol”=>“17.2125”, “calories”=>“34.425”}},
{“name”=>“g”, “nutrients”=>{“calcium”=>nil,
“satfat”=>“0.00714285714286”, “fat”=>“0.0285714285714”,
“carb”=>“0.0142857142857”, “fiber”=>“0”, “sugar”=>“0.00714285714286”,
“protein”=>“0.235714285714”, “sodium”=>“3.42857142857”,
“cholesterol”=>“0.607142857143”, “calories”=>“1.21428571429”}}]}}},
@response=#<Net::HTTPOK 200 OK readbody=true>,
@headers={“expires”=>[“0”], “last-modified”=>[“Fri, 27 Aug 2010 07:30:52
GMT”], “connection”=>[“close”], “content-type”=>[“application/xml”],
“date”=>[“Fri, 27 Aug 2010 07:30:52 GMT”], “server”=>[“Apache”],

Many thanks,
