I checked the ApplicationHelper class containing
But how do I dynamically set the tags in topic view. I used serialiser to insert
excerpt inside topic, but it had no effect on meta tags.
add_to_serializer :topic_view_ , :excerpt do # add custom fields to topic view excerpt end
If you can even point me to relevant code, it would be helpful, as I am not sure how to use
applicationhelper inside topic serialiser.
