Hi all,
Im writing a financial web application with Django and postgresql.
This application needs a lot of database transactions.
The Django Transactions Documentation is a little bit unclear for me,
so i have a some questions.
1. Using the transaction middleware, when is BEGIN TRANSACTION called?
2. Is it possible to have more than one
django.db.transaction.commit_on_success functions in a view?
3. Whats the default isolation level? (using postgresql)
4. How can I change the transaction isolation level (READ COMMITTED /
SERIALIZABLE)?
Is the following possible?
---
from django.db import transaction
@transaction.commit_manually
def viewfunc(request):
cursor = transaction.connection.cursor()
cursor.execute("SET TRANSACTION ISOLATION LEVEL SERIALIZABLE")
...
transaction.commit()
---
5. How handels djange a serialization error?
How can i catch the serialization error?
Thanks
Andreas
