Put your code on github. It could be a good oportunity to you train git, and for us, is an easier way to know what the context of your problem...

Does it not look natural to add a photo to an user? so... looks more natural a route like :user/photo/add translated to user_photo_add(@user) On Tue, Mar 4, 2014 at 6:04 AM, Colin Law <[email protected]> wrote: > On 3 March 2014 19:57, Alfredo Barrero <[email protected]> wrote: > > Good night everyone, > > > > My name is Alfredo Barrero and I'm getting started with RoR.
