Render default template on MissingTemplate Errors

问题

How can I catch the ActionView::MissingTemplate errors in Rails?

For example, my PeopleController has an Index method, but it doesn't need a template. When someone browses to root_url/people they get the default static error template.

And that's not the only controller with the issue; I want all missing template errors to redirect the user to my custom view.

1. How to catch the exception?
2. How to render a view afterwards?

Rails version - 3.0.19

Thanks in advance!

Which says:

Use 'rescue_from' in ApplicationController:

class ApplicationController < ActionController::Base
  rescue_from ActionView::MissingTemplate do |exception|
    # use exception.path to extract the path information
    # This does not work for partials
  end
end
