Trouble passing variable

Rails
1

I have a <% @user.comments.each do |comment| %>

and inside it is

<%= form_for [???, Subcomment.new],:remote => true do |form| %>

What can I use at ??? to ensure that the current @user.comment is
passed to the controller?

If I use

<%= form_for [comment, Subcomment.new],:remote => true do |form| %>

I get

No route matches {:controller=>“subcomments”, :comment_id=>#<Comment
body: “Comments coming up twice”, user_id: 2, commenter: “gleb”, id:
nil>}

Ive attached the page with the full code

Is it possible to do it this way? If not how can it be done?

Here you should put the comment the subcomment is for, not Comment. If
you do that then you shouldn’t need a hidden_field with the
comment_id.

   <%= form_for [Comment, Subcomment.new],:remote => true do |form|

%>


<%= form.text_field :body %>

<% form.hidden_field :comment_id ,index[1] %>


<%= form.submit %>


<% end %>
<% end %>

It insists that comment_id = Comment

What is the correct way to do this?

If I do that I get this in the terminal.

Why won’t it pass the comment_id when saving?

Strike last posting , there was an error in the controller. All OK now.
Still don’t know why I got the error in my first post.

Because your routes are setup to pull comment_id from the URL.
