better_errors is not working with Routing Error in Rails ?

[wangyandongnx]

It works great except that the default routing error page will be displayed instead of better_errors's page. Is this the right behavior?

That's the whole point of it. If you are looking to only make it available in your development. Consider grouping it under development in your gem file.

This seems like desired behaviour to me. AFAIK, routing errors like this in Rails are not 'true' errors, but rather a nicer 404 error page formatted like the Rails exception page. Please correct me if I'm wrong here.

In any case, the Rails routing error page seems more useful than Better Errors for this case, so I don't intend to fix or otherwise work around this.
