POHow to access JSON from a rails @variable?
text
Body
copied!<p>In rails I'm calling an API that returns JSON:</p> <pre><code>{"observations":{"realtime_start":"2012-12-27","realtime_end":"2012-12-27","observation_start":"1776-07-04","observation_end":"9999-12-31","units":"pca","output_type":"1","file_type":"xml","order_by":"observation_date","sort_order":"asc","count":"263","offset":"0","limit":"100000","observation":[{"realtime_start":"2012-12-27","realtime_end":"2012-12-27","date":"1947-01-01","value":"."},{"realtime_start":"2012-12-27","realtime_end":"2012-12-27","date":"1947-04-01","value":"-0.60853"} </code></pre> <p>In a controller I'm passing the JSON into an instance variable:</p> <pre><code># Send the http request response = Net::HTTP.get_response(uri) # captures the http response test = response.body #converts the http response hash from xml to json show_info = Hash.from_xml(test).to_json @it = show_info </code></pre> <p>Finally I render out the instance variable in a view:</p> <pre><code><script> x = "<%= @it %>" </script> </code></pre> <p>If I type x enter in the console, the json pops up formatted a bit differently which may be my problem.. </p> <pre><code> "{&quot;observations&quot;:{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;observation_start&quot;:&quot;1776-07-04&quot;,&quot;observation_end&quot;:&quot;9999-12-31&quot;,&quot;units&quot;:&quot;pca&quot;,&quot;output_type&quot;:&quot;1&quot;,&quot;file_type&quot;:&quot;xml&quot;,&quot;order_by&quot;:&quot;observation_date&quot;,&quot;sort_order&quot;:&quot;asc&quot;,&quot;count&quot;:&quot;263&quot;,&quot;offset&quot;:&quot;0&quot;,&quot;limit&quot;:&quot;100000&quot;,&quot;observation&quot;:[{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2010-10-01&quot;,&quot;value&quot;:&quot;2.39307&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2011-01-01&quot;,&quot;value&quot;:&quot;0.07892&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2011-04-01&quot;,&quot;value&quot;:&quot;2.47721&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2011-07-01&quot;,&quot;value&quot;:&quot;1.27864&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2011-10-01&quot;,&quot;value&quot;:&quot;4.09234&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2012-01-01&quot;,&quot;value&quot;:&quot;1.96053&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2012-04-01&quot;,&quot;value&quot;:&quot;1.25266&quot;},{&quot;realtime_start&quot;:&quot;2012-12-27&quot;,&quot;realtime_end&quot;:&quot;2012-12-27&quot;,&quot;date&quot;:&quot;2012-07-01&quot;,&quot;value&quot;:&quot;3.10599&quot;}]}}" </code></pre> <p>My question is how do I access one of the key value pairs? Do I need to parse it in javascript? Is there a way to do this through dot notation?</p>
