I am working through the official Getting Started with Rails tutorial
I am stuck on section 8.4 Generating a Controller. It suggests there
that this definition:
@post = Post.find(params[:post_id])
@comments = @post.comments
S ould be used in com ents_controller.rb. Surely that would make
http://localhost:3000/comments work, but it gives the error
Couldn’t find Post without an ID. That suggests a problem with the first
line of the definition. However that is what it says I should use in the
tutorial so I looked at post.rb and comment.rb and they are as directed.
Also checked routes.rb but all seems to be correct. Incidentally the
works fine and displays comments which I have to enter with the terminal
as http://localhost:3000/comments/new gives the same error.
I have been tearing my hair out with this for 3 days. Can somebody
please point out what I am doing wrong.
