From e35b98e6f5c54330245645f2ed40d56c74538902 Mon Sep 17 00:00:00 2001 From: Jeremy Daer Date: Fri, 13 May 2016 17:43:48 -0700 Subject: Action Mailer: Declarative exception handling with `rescue_from`. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follows the same pattern as controllers and jobs. Exceptions raised in delivery jobs (enqueued by `#deliver_later`) are also delegated to the mailer's rescue_from handlers, so you can handle the DeserializationError raised by delivery jobs: ```ruby class MyMailer < ApplicationMailer rescue_from ActiveJob::DeserializationError do … end ``` ActiveSupport::Rescuable polish: * Add the `rescue_with_handler` class method so exceptions may be handled at the class level without requiring an instance. * Rationalize `exception.cause` handling. If no handler matches the exception, fall back to the handler that matches its cause. * Handle exceptions raised elsewhere. Pass `object: …` to execute the `rescue_from` handler (e.g. a method call or a block to instance_exec) against a different object. Defaults to `self`. --- activejob/lib/active_job/execution.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'activejob/lib/active_job') diff --git a/activejob/lib/active_job/execution.rb b/activejob/lib/active_job/execution.rb index 7c4151fc90..4e4acfc2c2 100644 --- a/activejob/lib/active_job/execution.rb +++ b/activejob/lib/active_job/execution.rb @@ -34,7 +34,7 @@ module ActiveJob perform(*arguments) end rescue => exception - rescue_with_handler(exception) || raise(exception) + rescue_with_handler(exception) || raise end def perform(*) -- cgit v1.2.3
