I’am not able to catch ActionController::NoMethodError so I can  
display a own error message site.

Can someone give me a peace of code to check it?

How do you catch such errors and ActiveRecord:… error to display a  
own error message site?

I’m not sure I understand you correctly (you state you’re “not able”  
to catch Exceptions) but rescue\_action/rescue\_action\_in\_public was  
made exactly for this:

> **[ActionController::Rescue](https://api.rubyonrails.org/classes/ActionController/Rescue.html)**
>
> This module is responsible for providing rescue\_from to controllers, wrapping actions to handle configured errors, and configuring when detailed exceptions must be shown.

Rails 2.0 adds rescue\_from to handle different exceptions with  
different handlers:

Can you give me please a example how to display a own error page  
when a ActionController:NoMethodError occurs?

Thanx
