Hoping someone might be able to shed some light on what is wrong with
this. I am storing a list of 5 Objects in my datastore as a pickle in
a blob field and then trying to unpickle them and loop over them in my
template.
In my model I have declared a field:
negative_pages = db.Blob
Then I write my data to the field with:
self.negative_pages = pickle.dumps(self.pages.order('score').fetch(5))
And finally I declared a property to unpickle the data for use in the
template:
def display_negative_pages(self):
return pickle.loads(str(self.negative_pages))
In my template I am using {% for page in object.display_negative_pages
%} to loop over the objects
When I test it out using the shell everything works as I want it to
perfectly. However when I try and view the template one of two things
happens. If I try and load the pickle with pickle.loads(str
(self.negative_pages)) I get an error "Caught an exception while
rendering: '<'" from the pickle load. If I use pickle.loads
(self.negative_pages) I get an empty list returned.
So the question is what should I be looking at to resolve this? Why
would it work in the shell and not the template? Something Unicode
related?
Thanks
Adam
