BlogFunctions.GetDocumentTags() Not Working

Keith Donnell asked on July 29, 2015 16:16

The following code in my transformation is not displaying a list of tag links, as expected:

<%# Eval("DocumentTags") %>
<%# IfEmpty(Eval("DocumentTags"),"","Filed under: " + BlogFunctions.GetDocumentTags(Eval("DocumentTagGroupID"), Eval("DocumentTags"), "/Expert-Insights/Categories/Infrastructure/System-Center")) %>

The first Eval spits out "angry birds", cats, dogs, which is what I have set in the DocumentTags field for testing. DocumentTagGroupID is null/empty, and we do not need to limit to a specific set of tags.

So what am I doing wrong?

Also, are there any other helper methods I can use to simply get a list of the tags? I'm assuming based on the overloads of GetDocumentTags() that there is no way to control the markup that is returned.

Any help is greatly appreciated.

Your parent page needs to be assigned to a group. Tags belong to a group. So if you assign a tag group to your master page, then it will work fine. If you don't want to assign it to the whole site then just do the node you want the group to be assigned to. Fix is to simply add a group.

@Brenden - Thank you. Based on the documentation, tag groups come off as being optional. Adding the group and assigning it to the top-level blog node did the trick.

The second part of my question is still unanswered, however. As I expected, GetDocumentTags() generated a comma-separated list of links, however our design requires an unordered list, with no commas. How can I go about adjusting the markup?

This may be considered a hack, but I was able to figure out how to customize the markup.

I had to create a query:

select top 10 T.TagName, T.TagGroupID from View_CONTENT_BlogPost_Joined V
INNER JOIN CMS_DocumentTag DT ON V.DocumentID = DT.DocumentID

Then I created a "Repeater with custom query" web part and assigned the query, and set the where clause as:

V.DocumentID = {% CurrentDocument.DocumentID |(user)zbynekh|(hash)c8b27ab3e464c38c111b172ed3b8dbf72979ebe942aea889be9ae7a4adf9c526%}

and then created and set the transformation.

I hope this helps someone out in the future.

Keith you could also use the Replace() method like so vs. another query and nested repeater. Just find the commas and replace them with html elements.

    <%# BlogFunctions.GetDocumentTags(Eval("DocumentTagGroupID"), Eval("DocumentTags"), "/Expert-Insights/Categories/Infrastructure/System-Center").Replace(',', "</li><li>") %>

Hi Brenden,

Thanks for this help, your answer helped me. Is there any way to add '#' at the begining of each DocumentTag?

e.g I should get #angry brids, #happy monkeys..

Thanks, Chetan
