Description

It is easy to provide pages with lots of dynamic content using a variety of techniques including SQL, Reporting Add-on,   Scaffolding Add-on, Metadata Add-on, and  and other add-ons. Pages can always reflect the latest information (smile)! However, in some cases, it would be nice to have a snapshot of the page and its dynamic content at various points in time. This is possible with just a little bit of additional work and the run macro.

Dependencies

Run macro - used to capture the content in an attachment

Optional dependencies

In order to provide a better user experience for viewing the archived data, the following add-ons can be used

  1. Composition Add-on - deck and card macros
  2. Scripting for Confluence - groovy macro to automatically create decks/cards from the attachments
  3. HTML - used to display the captured HTML in a nice way on a Confluence page

Steps

  1. Create your main page
  2. On the main page, add the run macro surrounding the content that needs to be archived similar to the following

    No Format
    titleExample main page
    {run:exportFile=Example - Archive^example-$current_time.html
    |titleExport=Save page snapshot
    |exportVersion=replace
    |attachmentComment=Example-archive-$current_time
    |dateFormat=yyyy.MM.dd
    |autoRun=true
    |hideRun=true}
    
    {sql-query:datasource=testDS}
    select * from address
    {sql-query}
    
    {run}
  3. Create another page with the name equal to the original page suffixed by " - archive", suggest making it a child page of the main page. A simple alternative is to just use the attachments macro on this page - not as nice, but provides access to the data as straight html.

    No Format
    titleExample - archive page
    {composition-setup}{composition-setup} 
    
    {archive-deck} 
Tip
titleHow to archive charts

Charts can be handled by saving each chart as an attachment by adding some parameters to the chart macro similar to the following:

No Format
{chart:...
|attachment=Example - Archive^example-$current_time.png
|attachmentVersion=replace}

  • Output format wiki
