Any suggestions?
It should be [i] not (i) but a much more railsy way is params[:transport][:transports_transits_attributes].each do |attr| # do something with attr[:city] end However, I have to say that you seem to be doing rather unusual things which, when I find myself in such a situation, usually means I am tackling something in the wrong way. Can I ask why are you parsing the params in the first place rather than using them to build objects in the usual way?
