Batch tagging through console

Something quick that I think will work. Might want to verify against a couple of records first before uncommenting the line to add the tag. tag = Tag.find_by(name: 'soundcloud') category = Category.find_by(name: 'music') Topic.where(category: category).each do |topic| if topic.first_post.raw =~ /<your keyword here>/ puts topic.first_post.raw # topic.tags << tag end end
