How do I retrieve a model instance from the database without a model
instance?
For example from the doc[1] it has:
product = Product.objects.get(name='Venezuelan Beaver Cheese')
I want something like getInstance( 'Product', 'Venezuelan Beaver
Cheese' )
Here are the details of what I'm doing. I have multiple form models
that are all handled by the same post processing class. I'm using
django-celery to do the processing.
I want to do something like this in my view:
dbSave = form.save()
processTask.delay('Product', dbSave.pk)
Then in the task:
class processTask(Task):
def run(self, modelName, pk):
instance = getInstance( modelName, pk )
….
>From what I've read about django-celery, I shouldn't pass class
instances to the task so I need a way to pass/retrieve this info via
basic datatypes.
