Flask: sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked

[pythonpaul32]

Hi,

I am trying to update a database table and I keep getting this error:

'sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked'

None of the solutions online have helped and I am more confused than ever. Any help here would be greatly appreciated. Otherwise, I will have to remake the db.

Some will tell you that sqlite is not concurrent, however it is fully ACID compliant an can handle up to 50,000 inserts per second.
You should use transaction processing.
