API: Getting all posts in a topic


(Jay Pfaffman) #1

I’m working on a script that will evaluate participation in a discussion and produce a number based on how many messages they wrote, likes, and replies and such that will become students’ grade for “participating” in a discussion.

/t/blah/TOPIC_ID.json returns only 20 posts. Is there a way to get all of them, or will I need to do a request for all of them?

I looked a little at what gets passed to poll, but it wasn’t immediately apparent that I could somehow pass it something like a range or number of posts that I wanted.

Maybe the easiest way is to get the data I want from the data explorer plugin.

Now I’m thinking that it would be cool to write a plugin that showed people’s scores next to their profile pic in their posts in that topic.

When you GET /t/blah/TOPIC_ID.json the output will also contain a stream array that has all the id’s for the topic.

You then can call: /t/blah/TOPIC_ID/posts.json?post_ids[] and pass in all the ids from the stream array.

Thanks! And the problem with data explorer is that there is no way (that I can see quickly) to pass in the topic_id that I want.

Also its probably a good idea to still break up fetching all the posts into multiple requests rather than 1 big one. So if you have a topic with 100 posts. You should break it up into 5 smaller requests fetching 20 posts at a time.
