To append a tag to every topic on a forum, first ensure the tag is used on at least one topic. Then run the following (replacing `testing` with the name of the tag)

```plaintext
tag = Tag.find_by(name: 'testing')

Topic.where(archetype: 'regular').find_each do |topic|
 if topic.tags.exclude?(tag)
   topic.tags << tag
 end
end

```

To append a tag to every topic on the forum _that does not have any tags already_, first ensure the tag is used on at least one topic. Then run the following (replacing `testing` with the name of the tag)

```plaintext
tag = Tag.find_by(name: 'testing')

Topic.where(archetype: 'regular').find_each do |topic|
  if topic.tags.count == 0
    topic.tags << tag
  end
end

```
