Hi qinglau ,

 

Let me just clarify my understanding. You would like to display 4 blog topics  and exclude featured blog article from it. If my understanding is correct , this might be of help.

 

<#assign featuredThreadId = rest("/blogs/id/cs_blog/threads/featured").threads.thread.id />
<#assign blogList = rest("/blogs/id/cs_blog/topics").node_message_context />
<#assign counter = 0 />

<#assign limit = 4 />
<ul>
<#list blogList.message as blog>

<#if blog.id!=featuredThreadId && (counter< limit-1)>
<#assign counter = counter?number +1/>

<li>${counter} ${blog.subject} <br/></li>
</#if>
</#list>
</ul>

 

The above snippet is under the assumption , there would be only one featured article. If there might be more than one , we would have to change the code a bit. 

Since I have initialized the counter as 0 , I have checked for limit-1 .

You can improvise on this.

 

Hope that helps.

 

Thanks,

Sam

    Hi Guys, 

     

    thank you for the replying. During few days testing, i found out that two main issues in my current solutions. 

     

    1. When i am build the list of articles via my REST API call: 

     

             <#assign AllblogArticles = rest("${rootPath}/topics?restapi_response.style=view").node_message_context />

     

    The limit of this REST API call is 25 articles. Since we have more than 25 articles in our blog.

     

    2.  Next step, i create an new array  and stores all the articles into an array

     

     <#assign articles=[]>

     


    <#list AllblogArticles.message as msg> <#if msg.id!=featuredID> <#assign articles = articles + [ msg ] /> </#if> </#list>

     

    If there are plenty of users accessing our blog, we will have memory issues. 

     

    Still looking for a better way. 

     

    Cheers,
    Qing
