I assisted in looking into a Rails issue earlier with a friend. After making some modifications to some Ruby code he had an issue receiving exception emails which were generated by Rails. The rails plugin being used to accomplish this is called exception_notification and resolving the problem was simple. As you will see below instead of upgrading the entire plugin a couple lines in one ruby file were modified, the web server restarted, and the exceptions again started functioning properly. Below I display more of the error and the modifications made to resolve the error.

Rails Exception Notification Plugin Error Details:
If you receive a similar error it more than likely means that you need to upgrade the Rails exception_notification plugin. It appears that this error typically is associated with upgrading Rails to 2.1 and not upgrading the exception notification plugin however in this case Rails had been upgraded to version 2.1 long ago and the exception notification plugin had been working fine for some time so I am not sure specifically why this is the case but instead I only know how to resolve the issue.
Resolve Rails Exception Notification Plugin Error:
To resolve the error you will need to modify the exception_notifier_helper.rb located from the root of your Ruby project in the “vendor/plugins/exception_notification/lib/” directory. The modifications will be made to line 70 and line 76 of the file.
Modify Line 70 Of exception_notifier_helper.rb:
- -exclude_raw_post_parameters? ? @controller.filter_parameters(parameters) : parameters
- +exclude_raw_post_parameters? ? @controller.send!(:filter_parameters, parameters) : parameters
Modify Line 76 Of exception_notifier_helper.rb:
- -return @controller.filter_parameters({env_key => env_value}).values[0]
- +return @controller.send!(:filter_parameters, {env_key => env_value}).values[0]

I made the changes as you have suggested. But now getting the error ActionView::TemplateError (undefined method `send!’
Hello San,
It sounds as if maybe you made the modification to line 70 and possibly not to line 76. Double check the changes made to line 70 and 76 to verify they are correct but if they are and you continue to have issues it sounds as if you may have something else wrong that is outside the scope of this article.
Thanks.
