Hi Christoph,
All you need to do is re-raise the exception after you're done using it in
your rescue_from, so something along the lines of:
$ cat ./app/controllers/foo_controller.rb
...
rescue_from Exception do |e|
# do something with e before re-raising it ...
Rails.logger.debug("TEST: before re-raising ... e=#{e.inspect}")
raise e
end
...
def testfoo
x = 'bar' if 1/0
....
end
....
$ curl -sLi http://foo.localhost/testfoo
...
$ cat ./log/development.log
...
[c55f5] TEST: before re-raising ... e=#<ZeroDivisionError: divided by 0>
[c55f5] Completed 500 Internal Server Error in 17ms
[c55f5]
ZeroDivisionError (divided by 0):
app/controllers/foo_controller.rb:89:in `/'
app/controllers/foo_controller.rb:89:in `testfoo'
...
