after_filter for exceptions
Is there something similar to an after_filter that still runs if the action raises an exception?
I'm using an external logger (since I'm on Heroku); the response headers are filtered and logged in the after_filter. If an exception is raised, the filter doesn't run, and I don't have a log of the response header data.
If I try to hook into log_error or rescue_action_in_public, the response header won't be complete (since the actual render is called after these).
Is there another function that I can override that will be called at the equivalent time to an after_filter, but always run regardless of whether an exception is thrown?
Thanks!

Вы можете использовать around_filter и перехватывать исключения. Например,
# in a controller
around_filter :catch_exceptions
def catch_exceptions
yield
rescue ActiveRecord::RecordNotFound
permission_denied_response # gives a stock error page
end
Вы можете добавить around_filter в класс контроллера application.rb или в класс отдельного контроллера.
