How do I get message id from Post Page?

On the Post Page, I would like to display a message based on the topic's age.

 

To do this, I first need to retrieve the ID of the topic message that is being replied to. The following didn't yield any results...

 

<#if page.context.thread??>
  <div>topicMessage: ${page.context.thread.topicMessage.uniqueId}</div>
</#if> 
<#if page.context.message??>
  <div>message: ${page.context.message.uniqueId}</div>
</#if>

How should I be retrieving the topic message ID from the Post Page?

    Because the message context object is not available on the post page, I found that you need to resort to other methods.

     

    The solution I implmented was to parse the request url with freemarker to grab both the board ID and message ID.  

     

    Here is the freemarker code...

      <#assign boardKey = "board-id">
  <#assign messageKey = "message-id">

  <#assign urlString = http.request.url>
  <#assign strCount = 0>
  <#list urlString?split("/") as subStr>
    <#if messagePos?? && strCount == messagePos>
      <#assign messageID = subStr>
    </#if>
    <#if boardPos?? && strCount == boardPos>
      <#assign boardID = subStr>
    </#if>

    <#assign strCount = strCount + 1>

    <#if subStr == boardKey>
      <#assign boardPos = strCount>
    </#if>
    <#if subStr == messageKey>
      <#assign messagePos = strCount>
    </#if>

  </#list>

  <#if boardID??>
      <div>Board ID: ${boardID}</div>
  </#if>
  <#if messageID??>
      <div>Message ID: ${messageID}</div>
  </#if>

    Hi dustin,

     

    Did you try below context variable to bring the UniqueId:-

    ${env.context.message.uniqueId}

    Hi dustin,

     

    I have tried most of the context variables for getting message id on replay page but no one is giving message id.

    As a work around you can retrieve the message id from URL manipulation [not good practice].

     

    Please replay if you get any better solution for this.

    Hi mahesh_revanwar,

     

    What I can see is the Id that we have from the url is board  specific, It is not the actual Id of the message to which we are replying.

     

    So I don't thing this would be right approach to fetch the Id from the url. We may use local storage or session storage to carry the message Id at reply page.

     

    Regards,

    Vishwajit Shinde.

    Hi vishwajit_shind,

     

    If we get the board specific message id using that id we can get unique id of the message.

     

    Try this call

    <baseURLofCommunity>/restapi/vc/boards/id/<board-id>/messages/id/<message-id>

    Amazed this object still isn't available on such an important page.

     

    Either way, I found this, albeit ugly, to be the least required code to get the unique id

     

    <#assign u = http.request.url/>
    <#assign msg_non_unique_id = u?substring(u?last_index_of("/") + 1, u?length)/>
    <#assign msg_unique_id = rest("/boards/id/${coreNode.id}/messages/id/${msg_non_unique_id}/id").value/>
