Change the way parameter lists are handled internally Instead of trying to guess if a query key is a list (to strip the index number, since Rails expects list IDs without index number), we prefix the key name with the index when dealing with lists. E.g.: [0]ids: "one" [1]ids: "two" will be sent as ids[]=one&ids[]=two It makes it more reliable and let us differenciate between arrays and objects (objects are untouched and sent as-is).
