[PyQt] persistent database connection

[Anil]

Hi,
I am populating my table view using a QSqlRelationalTableModel,
It all works well and the application is working- Untill someone leaves it 
open overnight and tries to view/update data next morning. The tabe view does 
not show anything, can't add/delete/update ,no error messages are produced. I 
suspect  connection to the database is getting timed out. How can  I prevent 
it from timing out or how to detect if the connection behind the model is down 
I tried 
"if  connection.open():"
before executing the Query, without success

Any help is much appreciated.
