error-message

I am using Ruby on Rails 3.0.7 and I would like to use the pluralize method in a my model file in order to properly build custom error messages.

For example, I would like to do something like the following:

NAME_MIN_LENGHT = 2 # Is 2 but I plan to change that (maybe dynamically... if it is possible) in future development

validates :name,
  :length     => {
    :minimum        => NAME_MIN_LENGHT,
    :too_short      => "is too short (minimum is #{pluralize(NAME_MIN_LENGHT, "character")})",
  },

How can I do that? Is it advisable? Why?
