todos.json() returns a list of dictionaries, each one being a row. in js terms, it's an array of objects.
skimming through handsontable docs <http://handsontable.com/demo/datasources.html>, you can use an array of objects to populate the table, but if you want your own headers (and possibly in order) you should specify not only "data" but also "colheaders" (if you want headers not to be "A", "B", "C", etc) and "columns". you can "forge" a "columns" array easily, with all the fields in the correct order (needs to be put in json if you pass it on the view) [{'data': f} for f in db.todo.fields] On Wednesday, April 8, 2015 at 11:03:02 PM UTC+2, Tom Campbell wrote: > > I have a query result named todos I am loading into a Handsontable in the > view.
