python sqlite Error IntegrityError: UNIQUE constraint failed: table_area1.user_name
This error is caused by the fact that when you were building the table, you set the key to be UNIQUE. When a user with the same name appears, the user will report

for example you insert something with id 1
and then you insert something with id 1 because you can only have one field with id 1 so you get an error here
