How To Process Server Side Parameter Sent From Jquery Datatables Using Flask?

I am having some issues in processing the parameters sent by jquery datatables 1.10 when server side processing is enabled. I initialized the datatable in the javascript side like

Solution 1:

Get DataTable to send json

ajax: {
    url: "/api/data_table",
    type: "POST",
    data: function ( args ) {
      return { "args": JSON.stringify( args ) };
    }
},

In flask, parse the json

args = json.loads(request.values.get("args"))
columns = args.get("columns")

Solution 2:

You can use this little nifty package that I found https://github.com/bernii/querystring-parser

from querystring_parser import parser
args = parser.parse(request.query_string)
print args['columns']
