title: Django json strategy?
body: <p>I am using wunderground's json api to query for weather conditions on my site. The api gives me a nice json object with all the neccesary data, but I am limited to a number of calls per day. What would be the preferred way to store this data?</p>
  
  <p>I was thinking to dump the json to a file, and check for it's timestamp: if it's say older than 60 minutes, then fetch the new one and overwrite, if it  is not, read the file from the disk. I wouldn't create a database table just to store weather data that I don't essentially need. Is there some clever Django way of caching this process or should I do it manually?</p>
