Hello, I need to ensure that when I update a record in a table, it must comply with these requirements: 1. Begin transaction - don't allow anyone else to write to that record/row. 2. Write and commit the updated record. 3. End transaction, allowing everyone to write to that record/row. 4. There can only be 1 transaction per record/row at the same time. 5. If anyone tries to write while a transaction is in place either receives an error or some kind of message that identifies that the record is being updated.
Does anyone know if web2py/DAL allow me to do/have this? I'm using SQLite and apparently it only does database lock (not record/row or even table). But I willing to accept that if I can follow the requirements above replacing record/row lock with database lock. Another option is to change the db backend to MySQL or PostgreSQL if only they would comply with the requirements above.
