Ruby on Rails link_to route path while preserving original query string parameters

I have a URL like so http://example.com/?sort=pop

In my view I am using link_to category.name, categories_path(category)

How can I preserve any query string parameters that might already exist on the requesting URL?

So the final link URL would be http://example.com/categories/1?sort=pop

<%= link_to category.name, category_path(category,
  request.parameters.merge({:new_params => 42}) ) %>

This should link to the right path, preserve existing parameters and add any new params you might have.

Anthony's solution almost worked for me. However, it didn't like just having params as one of the passed through variables. Instead, I had to add params: or :params => to the link. It works just find for me now.

<%= link_to "XLS ", users_path(format: "xls", params: params) %>

<%= link_to category.name, category_path(category, params) %>

Should do the trick

Take care that the default route helper to access a specific Category is category_path. Singular since it's for only one category, makes sense!
