I think people will see clearlier your code if you use the forum code formater (Ctrl+Shift+C on selected text).
In my humble opinion, your code would gain also a lot of readability if you use Phoenix contexts. If you don’t already followed the official guide, please try it and you’ll find how Contexts are really useful.
Also the routing guide as well as phoenix generators like Context generator, html genrator may be helpful. The generators are good prototype tools to generate code that you can cheat on to write your own. ^^
