Undefined Method for `topic_comment_path`

After I make a comment for any particular post and submit the comment via the Create action to add the comment to the database, I get the error Undefined Method for topic_comment_path. From the error, it looks like the route path is not picking up the local variable comment that I am looping through(@post.comments.each do |comment|) in the show.html.erb file? When I refresh the page, and go back and check the post I see the number of comments has increased due to the post being created. But I can't view the comment after I create it on the Posts#show view. Can anyone offer any assistance?

From Show.html.erb file

<% if @post.comments.present? %> 

<h1>Comments</h1>
<% @post.comments.each do |comment| %>
  <div class="media">
    <div class="media-left">
    <%= image_tag(comment.user.avatar.small.url, class: "media-object") if comment.user.avatar? %>
  </div>
<div class="media-body">
    <small>
      <%= comment.user.name %> commented <%= time_ago_in_words(comment.created_at) %> ago
      <% if policy(comment).destroy? %>
        | <%= link_to "Delete", [@topic, @post, comment], method: :delete %>
      <% end %>
    </small>
    <p><%= comment.body %></p>
</div>
  </div>

<% end %>

From routes.rb file

Rails.application.routes.draw do


get 'comments/create'

devise_for :users


#the resources method lets you restrict which RESTful routes you want
resources :users, only: [:update] #creates new action users#update
resources :topics do
resources :posts, except: [:index] do
  resource :summaries, only: [:create, :show]
  resource :comments, only: [:create, :destroy]
end

end

get 'about' => 'welcome#about'

root to: 'welcome#index'
end
