Ruby on Rails
Tuesday, January 26, 2016
I'm pretty new to ruby as well but I think the problem is that the Rails router doesn't know what to do with a POST request to "/home/new". I think you just have to add this line to routes.rb:
post 'home/new', to: 'home#new'
Like I said I'm a newbie myself so I'd love it if someone could correct me if I'm wrong or let me know if I got it all.

Hello all, I'm new to ruby and I am having trouble with adding new data
(name, height, weight, etc). Everytime I try to save my data, I get
this error:
No route matches [POST] "/home/new"

Request

I am able to view index and enter the information, but when I submit, I
get this problem. Any help would be appreciated! Thank you
