Optimistic locking library for Django
Project description
django-concurrency is a optimistic locking library for Django 1.4.
It works adding a VersionField to the model, each time a model is successfully saved the VersionNumber is incremented.
How it works
sample code:
from concurrency.fields import IntegerVersionField
class ConcurrentModel( models.Model ):
version = IntegerVersionField( )
Now if if you try:
a = ConcurrentModel.objects.get(pk=1) b = ConcurrentModel.objects.get(pk=1) a.save() b.save()
you will get a RecordModifedError on b.save()
