title: Filtering Posts in Feed - Rails 4
body: <p>I'm working on a Rails app based on the railstutorial.org book/tutorial. I've added some attributes to my post so that a post has an offered pay and a date (in the future). </p>
  
  <p><strong>I'd like to filter the feed based on user selected filters such as posts where the pay is between x and y, and the date is before xyz, etc.</strong> 
  After searching online I considered scopes to accomplish this, but don't fully understand them and didn't find good documentation for them. 
  I need a way to temporarily store the filters the user selects and use them to query the database and return the correct posts. </p>
  
  <p>I've successfully gotten the information from the view to the controller, but am struggling finding a good way to store the filter settings in my application to use between controller actions. </p>
  
  <p>Does anyone have any suggestions on how to attack this issue? I'm not sure what code would be useful, but let me know and I can upload the files. Thanks!</p>
