I have no idea why this is not working, I\'m learning rails and I\'m following a book it says to do it like this:
<%= form_for([@article,@article.comm
Change:
[@article,@article.comments.new ]
for
@article
I suggest you reading the API on the related section : http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html
