Posted in Articles has_many tags and tags has_many articles - best way to get tag names uniq

Hi there Nikodem,

First, a tiny nitpick with your naming—what you're calling ArticlesTag, I would rename to ArticleTag. It's just one tag for one article.

Now, to get all the tag names that've been assigned to at least one article, you can do something like:

Tag.joins(:article_tag).distinct.pluck(:name)
