Rails - saving search query / result

Question

I have a search page that finds candidates. On this page, you can view the click to find additional information about the candidate. When on the candidate’s submission you can click “Change” or perform a number of other actions that will also return the candidates submission to you.

My problem is with the submission of candidates. I need to add a button to return to the search results. I initially thought about using a JS button with a history of -1, but since the user can perform other actions from within the view, this will not work.

I’m still completely new to rails, so I’m not sure of my capabilities ... I think this is some kind of caching of results, and then maybe a hidden field to track the location of the cache (do not think that this is the best solution, since tracking hidden value may become unavailable!)

Thanks, Alex

Answer 1

I would probably use a session variable to store this information.

First, make sure that your form on the search page is a GET operation, so that the search data is in the query string. Then in your search action, you can grab the request URL and save it in the session:

session[:search_results] = request.url

, , " " :

link_to "Back to search results", session[:search_results]
