How to get parent node in Capybara?

I'm working with many jQuery plugins, that often create DOM elements without id or other identification properties, and the only way to get them in Capybara (for clicking for example) - is to get their neighbor (another child of its ancestor) first. But I didn't find anywhere, does Capybara support such things for example: find('#some_button').parent.fill_in "Name:", :with => name ?
