Question

In my datagrid I read from database dumped in json using tornado server
It looks like this if api/notes visited:
{"total": 0, "rows": "[]"}
(table is empty initially, user supposed to fill it…)
And ofcourse dataSource is:

   transport: {
      read: {
        url: '/api/notes/',
        dataType: 'json',
        type: 'GET',
      },


      parameterMap: function(options, operation) {
        var map = {};
        if (operation == 'read') {
            map.page = options.page;
            map.rows = options.take;
            map.sort = options.sort;
            if (map.sort) {
              map.sort = map.sort[0];
              if (map.sort) {
                var t = map.sort;
                map.sort = t.field;
                map.order = t.dir;
              }
            }

on page load i get Uncaught ReferenceError: uid is not defined

chrome dump:

Answer 1

The problem was that I fed client with unparsed json
Wrapping data in json.loads() did the trick
