render default template when requested template is missing in Rails

Question

For a plugin I want to hack the following feature into Rails:

When a (partial) template does not exist (regardless of the format) I want to render a default template

Answer 1

Solution 2:

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

Drawback: does not work for partials.
