Is the ActionText call form nice in the model?

Question

Is it permissible to call ActionText from ActiveRecord?

def last_updated
  updated_at? ? "Updated #{ActionText::time_ago_in_words(updated_at)} ago" : "never updated"
end

Is there an argument against doing something like this? Should this be a helper method?

Answer 1

Yes. According to strict MVC teachings, this is a bad form and belongs to an assistant.

In theory: this particular piece of functionality is presentation-specific, so, according to the teachings of MVC, it refers to a view helper.

In practice: it really doesn't matter. I believe ActionText is parsed when loading the server / console. This means that the file does not need to be downloaded again. Also, calling a method directly rather than enabling an ActionText is probably better on the part of memory management.
