Render custom 404 page in Rails 2
Tell the application controller how to handle exceptions, here a
Do this with the following line:
rescue_from ActiveRecord::RecordNotFound, :with => :render_404
This will call the method
render_404 whenever a
RecordNotFound error occurs (you could pass a
lambda instead of a symbol, too).
Now write this method:
def render_404 render 'errors/404', :status => '404' end
Finally create a 404 document
%h1 Record Not Found .error The record you requested could not be retrieved in my database.
Any 404 error that is caused by something not found in your Rails app will render a nice message using your default layout. Similarly, you may catch and handle any other error.
