Question

view:

<% @post.comments.each do |comment| %>
  <p>
    <b>Comment:</b>
    <%= comment.content %>
  </p>
  <p>
    <b>Commenter</b>
    <%= link_to comment.user.username, comment.user %>
  </p>
  <p>
    <b>Link</b>
    <%= link_to "Show Post Comment", [@post, :comment] %>
  </p>
<% end %>

contoller:

class CommentsController < ApplicationController
  def show
    @comment = Comment.find(params[:id])
  end

etc…

route:

Sandbox3Devise::Application.routes.draw do         
  resources :posts do
    resources :comments
  end

etc…

If I click <%= link_to "Show Post Comment", [@post, :comment] %> of a post with id 48
I get this:

http://localhost:3000/posts/48/comments/48

Any suggestions to fix this?

Answer 1

If you want to link to a single comment, use

<%= link_to "Show Post Comment", [@post, comment] %>

:comment is a symbol, not a reference to comment.
