Float Thread sorting and order

I am using the fllowing REST Api to fetch the floating threads, i need them to be sorted and like the newest thread created to be on top. 

 

/restapi/vc/categories/id/CAT-ID/subscriptions/global/float/thread

 

Thanks

    If I understand correctly, you want to get a list of floated threads sorted by the date of the root post. In your sample code, it looks like you're sorting messages within a thread, rather than sorting the list of threads.

     

    Here's a quick example of sorting the list of floated threads (community-wide) by the date of the root post (most recent first):

    <#assign floated_threads = rest("/subscriptions/global/float/thread").subscriptions />
<#list floated_threads.subscription?sort_by(["target","messages","topic","post_time"])?reverse as subscription>
${subscription.target.messages.topic.id} - ${subscription.target.messages.topic.post_time} <br>
</#list>

     So basically I get the list of floated threads across the entire community, iterate through the list sorted in reverse order by post_time, and then output the id and date of the root post.

     

    I want to point out that in this case the sort_by is taking a sequence of 4 values which correspond to the names of the nested subvariables. For example, the post_time of the root post as I'm looping through the subscriptions is accessible via "subscription.target.messages.topic.id", so my parameter for "sort_by" is the sequence "["target","messages","topic","post_time"]"

     

    I hope this helps!

    Hi Gursimrat,

     

    I don't believe that particular REST API call supports any parameters for sorting; however, you should be able to sort the threads after the fact using the Freemarker "sort_by" built-in:

    http://freemarker.org/docs/ref_builtins_sequence.html#ref_builtin_sort_by

     

    Here's an example of how that works blogs:

    http://lithosphere.lithium.com/t5/developers-discussion/Sorting-blogs-by-alphabetical-order/m-p/38272#M647

     

    The approach should be similar for threads.

     

    I hope this helps!

      It is not working. I need to sort it based on "post_time" 

       

      My FTL Code

       

      <#assign floating_threads = rest("categories/id/10023/subscriptions/global/float/thread").subscriptions/>

<#list floating_threads.subscription as fth>
<#list fth.target.messages.linear.message?sort_by("post_time") as t> 
<li>
<a href="${t.@view_href}">${t.subject}</a>
</li>
</#list>
</#list>

      It returns the following xml 

       

      <subscription type="subscription" href="/subscriptions/global/id/411">

      Can you let me know where the problem is?
