You shouldn't be thinking about controllers here at all.

Since the data that has to be processed is in the Micropost, why not
have the hashtag creation method there?

If you invoke that method on a callback like before_save, then you'll
be able to edit the post and have the hashtags updated each time.

Alternatively you could use a "factory" class to build the hashtags
with the Micropost as the input.

HTH!
