I have a rails application running on a shared server. As I can’t
install gems on it, I was going to put my own lib on the server if it
couldn’t find the gem. My code was as follows (in the controller)
begin
require “rubygems”
require “payment”
rescue
$: << “/home/username/rubylib”
require “payment”
end
The problem is that the rescue doesn’t get processed. When it hits the
require at line 3, the app dies. I know that the code from line 5 ($: <<
…) works as I’ve tested it with irb as well as put it standalone in
the controller on the shared server. If the rescue were processed,
everything would be fine.
Does anyone know how to get a recovery in this situation?
Thanks in advance

Yes: you need:
rescue LoadError
rescue by itself only catches StandardError and its descendants.

If I remember correctly, gems and rails plugins have the same basic
structure (as far as loading goes) and you can unpack a gem into the
vendor/ directory. This would seem to be easier than what you’re
trying here…

A rescue clause without an explicit error class defaults to
StandardError. A failed require raises a LoadError, which is not a
subclass of StandardError. Change ‘rescue’ to ‘rescue LoadError’ and it
should work as expected.
