Hi Jeff, thanks for your reply! I found the article here: http://www.simonecarletti.com/blog/2009/11/re-raise-a-ruby-exception-in-a-rails-rescue_from-statement/
And he mentions that re-raising does not work since rails won't catch it anymore.. has this been changed since? I generally thought there might be a better way, as usually re-raising exceptions is considered to be bad :) Thanks a lot, Christoph On Tuesday, 12 November 2013 19:07:00 UTC+1, Jeff Lewis wrote: > > 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' > ... > > Jeff > > On Tuesday, November 12, 2013 6:40:12 AM UTC-8, sol wrote: >> >> Hi there, >> >> I'm using Log4r in my rails projects.
