You left out some critical code from the original question -- your
Javascript sends each post request twice:
function send_data(id){
$.post("{{=URL('contest','flip_contest_status')}}", {id: id} );
$.post("{{=URL('contest','flip_contest_status')}}", {id: id} )
.done(function(data) {
window.location.replace("{{URL('contest','configure')}}");
});
}
If you delete that first $.post line, everything seems to work fine. One
other problem, though:
def flip_contest_status():
id = request.post_vars.id
row = db(db.contest.id == 13).select(db.contest.running, db.contest.name
).first()
You probably forgot to revert after debugging, but above you have
hard-coded and id of 13 into the query.
