As far as I can tell there's no 'preferred' way to do this instead of using overwrite_params and this is extrememly usefuly in situations where it's hard to know exactly which parameters will be set in a view (for instance filtering a few of multiple options using query string params).
Ditto. I've returns to a small rails app after a while to discover overwite_params is deprecated, and I havn't found out why yet. Presumably the workaround is to DIY and take everything from request.params replacing the bits you want to.
(for instance filtering a few of multiple options using query string params).
Yes exactly what I use it for.
Will this work ok?
instead of: <!-- <%= link_to 'All', url_for(:overwrite_params => {:listing_type => nil}) %> --> this: <%= link_to 'All', url_for( request.params.merge({ :listing_type => nil}) ) %>
