How can I check the last letter of a string?

Question

I have the following code:

<%= "#{@resource.first_name.capitalize} " + "#{@resource.last_name.capitalize}" + "'s Area" %>

which prints stuff like:

Tom Byrne's Area, or Mark Kelly's Area

It would be really cool though if I could avoid things like:

Jean Collins's Area, or Paul Harris's Area

and use the correct grammar like:

Jean Collins' Area, or Paul Harris' Area

Anybody know how I could write some code that would write "'s Area" if the last letter of last_name is not "s", and write "' Area" if it is "s"?

Answer 1

To get the last character of a string: str[-1].

You might look if someone else has done this, since there are several special cases. A quick google search yielded the possessive gem.
