AttributeError: 'Context' object has no attribute 'has_tags'

[lucid]

After updating (Trac 12.2, DiscussionPlugin r9877) I get the following error when using the RecentTopics macro:

AttributeError: 'Context' object has no attribute 'has_tags'

Lastest revision is commit of unfinished work on TagPlugin support. Use some older revision for now.

Ok thanks for the information. Is there a known stable / preferred latest version? It might be a good idea to mention this on the wiki page under PluginVersions?

[Radek Bartoň]

Wiki page updated, thanks for provoking me to it :-).

You're welcome ;) Thanks for the update

Here is a small patch that fixes the issue, but I have no real idea if that's a smart one :

[Ryan J Ollos]

(In [12141]) Fixes #10461, Refs #8832: The components tracdiscussion.tags.DiscussionTags and tractags.api.TagSystem must be enabled in order for TagsPlugin support to be enabled. This is a workaround that will likely be improved on in #8832 as the tags module is redesigned.

[Ryan J Ollos]

The implementation of tags needs to be refactored/redesigned, but we can just fix this issue for now. Please report back if it is working after upgrading to the latest revision of the 0.11 branch.

Works well. Thanks.
