If you’re talking about this plugin and not polls:
- A user can only submit one rating per topic. Once you’ve submitted your rating, you can still post in the topic, but the rating controls will not appear in the composer again.
- Rating controls will appear in:
- Topics in a category with ratings enabled
- Topics with a ratings tag
As @cpradio said, this plugin uses both
PostCustomFields, however I can’t see any reason why moving a topic from one category to another would affect the ratings control visibility logic. The logic for deciding whether to show the ratings controls in the composer is dependent on
CategoryCustomFields which are not being migrated in this case.
Topic and post custom fields are used to store ratings and average ratings, not to decide whether to show rating controls.
