get_slice_from_storage - NotImplementedError()

[robintema]

Hi,
I try to build a notification system and I want to use feedly for it.
I have created a simple demo to test how the library works. The use case looks like this:
love = Love()
feed = MyNotificationFeedly()
feed.add_love(love)

I have followed this example: https://feedly.readthedocs.org/en/latest/notification_systems.html

However add_love() throws an exception which is raised in feedly/storage/base.py:270

I have checked the code and it seems that the get_slice_from_storage() is not implemented. I was just wondering how does the notification system work on Fashiolista if a such simple demo is not working for me locally.
Could you please help me?

Hi!

The code is pointing to the base storage implementation (expected would be Redis or Cassandra)
It seems there is a typo in the notification tutorial.
Instead of subclassing NotificationFeed, please subclass RedisNotificationFeed.
(Basically the same thing, except that it's setup to use Redis as a storage backend.)

We should raise a better error message when using Feedly like this.

PS.
If I may ask, what are you building using Feedly?

I've added issues #40 and #41

Thanks for the quick response. I have to build a facebook like notification system for a social learning site.

Thanks again.
