QUESTION
I'm trying to setup stream-framework the one here not the newer getstream. I've setup the Redis server and the environment properly, the issue I'm facing is in creating the activities for a user.
I've been trying to create activities, following the documentation to add an activity but it gives me an error message as follows:
...ANSWER
Answered 2021-May-29 at 15:41The documentation is inconsistent. The verb you pass to the activity should be (an instance of?*) a subclass of stream_framework.verbs.base.Verb. Check out this documentation page on custom verbs and the tests for this class.
The following should fix the error you posted:
QUESTION
I'm running across an extremely strange bug while using GetStream: i'm running a script to migrate over 200k activities (previously used an internal stream-framework fork) and I'm running across a really bizarre issue.
The problem is this: I'm setting the 'time' field to a custom value (usually in the past). Now: these activities are being ordered wrong by the API.
Although the activities being added have correct, ISO8601 UTC times in the past, the oldest ones are coming back on top of the feed (mixed with only a couple of new activities).
This is really odd and I'm at the end of my wits -- this seems like an issue on Stream's end.
Thoughts? Below is a screenshot of the issue.
...ANSWER
Answered 2020-Jul-10 at 14:30Surprisingly, it works as expected because API considers last n operations to build the feed. After retrieving these operations, they are ordered according to time. That's why if you add old activities, they are the only operations to build the feed.
Workaround to this is that adding activities in reverse order such that insert old activities first and new activities last then you will be able to read the new ones.
Moreover, if you are importing a lot of activities, you might consider import feature.

Install Stream-Framework
You can use Stream-Framework like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
