Thanks for a great tutorial. However, I ran into the following error after I had finished building the comments. What could be wrong? I am using Rails version 2.3.4.
post_comment_url failed to generate from {:action=>"show", :post_id=>#<Post id: 1, title: "11", body: "body1", created_at: "2009-11-13 16:42:33", updated_at: "2009-11-13 16:42:33">, :id=>#<Comment id: nil, commenter: "boo", body: "boo", post_id: 1, created_at: nil, updated_at:
, :controller=>"comments"}, expected:
{:action=>"show", :controller=>"comments"}, diff: {:post_id=>#<Post id: 1, title: "11", body: "body1", created_at: "2009-11-13 16:42:33", updated_at: "2009-11-13 16:42:33">, :id=>#<Comment id: nil, commenter: "boo", body: "boo", post_id: 1, created_at: nil, updated_at: nil>}
