If you’re doing a form post to a nested resource, like creating a comment under
/posts/1/comments/
with a route like
map.resources :posts do |post|
post.resources :comments
end
you have to account for that when you’re creating a form, you can’t just send it to the comment and hope everything will work out.
It took me a little time to find this, so I’m posting it in hopes of making someone else’s day easier. What I had to do was
form_for([@post,@comment])
and now everything is happy again.

I made an account just to reply to this and say “thanks” for solving this exact problem for me. This was the second result (after the Rails API) when I searched for “rails nested resources form”.
Perfect.
