geocorrect's Issues

Web: 500 on all the 404 Urls

Problem
So when you visit any URL like http://localhost:5000/fawfawf

The function show_map
Assumes it as venue_id and tries to fetch data but SQLite database returns nothing Hence resulting in 500 due to UnboundLocalError in get_map_obj function because fetch_data
does not have any checks(error return code) when the data is not in SQLite database

Solution
Take care of No Data condition and return error codes or trigger 404
