Sorting blogs by alphabetical order

Hi there,       I'm using a REST API call like this       /restapi/vc/boards/style/blog/nested/       in order to iterate through a list and populate a component with links  for such blogs. Is ...

Hi Adam,

 

     The built in is working just fine. I'm now facing a REST API call issue.

 

     I'm trying to retrieve certain Community's blog list with

 

          <#assign global_blogsCount = rest('boards/style/blog/nested/count').value/>  

 

     However, when I try to use this value for a very simple calculation such as

 

          <#assign leftColumnEnd = (global_blogsCount/2) />

 

     I get the following error.

 

          Expression global_blogsCount is not numerical

 

     Could you please advice?

 

Gracias,

Luis

As far as freemarker is concerned, the value you're getting back is a string. So if you want to use it as a number, you need to convert it. There's a "number" built-in that can be used with strings. For example:

 

<#assign global_blogsCount = rest('boards/style/blog/nested/count').value?number />

 In case you're curious, you can find a full listing of the available freemarker built-ins here:

http://freemarker.sourceforge.net/docs/ref_builtins.html

 

I hope this helps!

    Thanks Adam,

     

         That worked out the issue. Could you please point out what's wrong on this snippet?

     

         <#if (global_blogsCount % 2) == 1)>

              <#assign leftColumnEnd = (leftColumnEnd?int) + 1 />
         <#/if>
         <#list global_blogs.board?sort_by("title") as blog>
              <#if gblogIdx != 0>
                   <#if (gblogIdx == (leftColumnEnd + 1) >
                        <#assign blogMenuContentAlpha = blogMenuContentAlpha + '</div><div class="hp-sub-nav-row blog-list-right">' />
                   <#/if>

              </#if>
               <#assign blogMenuContentAlpha = blogMenuContentAlpha + '<div class="hp-nav-col"><ul><li><a href="${blog.@view_href}">${blog.title}</a></li></ul></div>' /> <#assign gblogIdx = gblogIdx + 1 />
         </#list>

     

          Lines in bold are breaking my code

     

    Gracias,

    Luis

      It looks like the second bolded line of code has an unmatched parenthesis, so that could be one issue. Does fixing that resolve everything? If not, could you reply back with the details of the error message you're receiving?

        Thanks Adam

         

             In addition to that, there were another syntax errors. Will keep debugging
