How do I fetch all records which belong to a user and show only the records with distinct name?
Question
Tagmap.where(user_id: current_user.id).uniq(:name)
This query doesn't seem to work. It still fetches all the records belonging to that user only.

您可以使用group by SQL查询。
Tagmap.where(user_id: current_user.id).group(:name)
