Rest API call issues for Labels in Forums

Hi Lithium Support,

 

I'm currently working on customized page to show forum threads filtered by a Label but I've come across a strange issue that the call returns the full list of threads in a topic regardless of what label text is passed. Take for example a Rest Call made to this Lithosphere topic:

 

http://lithosphere.lithium.com/restapi/vc/boards/id/lisupport/threads/for/labels/text/nonexistantlabel/recent/

 

Which returns the same threads if I use the following call:

 

http://lithosphere.lithium.com/restapi/vc/boards/id/lisupport/threads/for/labels/text/recent/

 

Whereas similar API calls for category of type Blogs and Ideas work ok. For example:

 

http://lithosphere.lithium.com/restapi/vc/boards/id/scienceofsocial/threads/for/labels/text/Engagement/recent

 

Returns at least 3 threads

 

http://lithosphere.lithium.com/restapi/vc/boards/id/scienceofsocial/threads/for/labels/text/nonexistantlabel/recent/count

 

As expected, this doesn't return any threads.

 

Is there a special REST parameter that Forums require to be filtered by a Label?

    You are correct, there is a bug with filtering forum threads based on labels. This is due to a lot of special handling of search based legacy code. 

     

    However, are you sure that you need the entire thread? It sounds like you are making a list of the topics (root messages) with specific labels. If this is the case, you can filter boards/topics on labels (notice the filters in the blue box at the top).

     

    Let me know if you need a list which includes the entire thread instead of just a list of root messages and we will continue to look for another way.

    That's funny I've got a very similar problem just now...For me it works perfectly if a bord is a tkb, but not for a forum.

    I will look deeper into that tomorrow...I'm tired.

    I've got the same problem here and it's still not working for me. It's really confusing...and hard to explain but I will try.

     

    To simplify, I've got a categorie. Whithin this categorie I get all the labels with :

    server_url/restapi/vc/categories/id/${cat.id}/labels/labels?restapi.response_style=view

     

    Unitil there no problem, I've got 3 labels.

    Then I want to get the threads for those labels by board

     


    For this I use 

    server_url/restapi/vc/boards/id/${myBoardId}/threads/for/labels/id/${label.id}/recent/

     

    And there is the problem.I checked with count, and if 'myBoardId' is a tkb, I've got the good count for any label ID. But if 'myBoardId' is a forum I always get 1 when I should have 1, 0 and 0. And it's always the same board wich is return no matter the label ID. How can the same board be return for 3 differents label ?

     

    I can't figure out the problem.I'm not sur if I'm missing something or if it's just a bug.

     

    Can someone help me on this ?

    Have you tried using the topics argument instead of threads, like so? 

     

    server_url/restapi/vc/boards/id/${myBoardId}/topics/for/labels/id/${label.id}/recent/

    Wow, it works with topics.

    I don't understand why it's not with threads, is that a bad practice to use it ?

     

    Anyway, thanks a lot !
