Touching nested attributes


I'd like to suggest a patch for rails, but dont know what should I do
to be able to create tickets in lighthouse.

So the patch is about nested attributes. When we assign them, it would
be nice to `touch' the record itself. For example, it is useful when
you cache fragments with the cache key based on record's timestamps (<
% cache @thing do %> ... <% end %>), and in those fragment you render
some information about the associations of the record.

Here is the patch:

Can it be useful for you? Does it worth to be submitted in lighthouse?
How can I do it?



Hi Ivan,

The Contributing to Rails guide[1] is a good place to start.

Good luck.
