Rails datatables ajax json 414 request URI too large

Question

So I've tried the Railscasts tutorial, as well as the one for the ajax-datatables-rails gem. I'm creating a list of clients from a database--not users. I believe I've narrowed it down to the fact that when using the GET method via Datatables' sServerMethod, I receive a 414 with "Request-URI too large". When I use the POST method, I simply get null values for all attributes except id which makes sense since the POST json is used for creating a client. Any help is greatly appreciated!

Here is my code and diagnostics response:

// custom.js    
$("#datatable").dataTable({
        "bJQueryUI": true,
        "sPaginationType": "full_numbers",
        "bProcessing": true,
        "bServerSide": true,
        "sAjaxSource": $('#datatable').data('source'),
    });

Response:

http://127.0.0.1:3001/clients.json
Request-URI Too Large

Answer 1

Managed to fix the error by installing the gem thin.

Add this line to your Gemfile if you are having this issue:

gem 'thin'
