        </strong>
        <br/>
        <%= comment.body %><br/>
        <%= link_to 'Delete Comment', comment, method: :delete %>

<% end %>

In /app/controllers/comments_controller.rb,

class CommentsController < ApplicationController
  def create
    @post = Post.find(params[:post_id])
    @comment = @post.comments.create!(params[:comment])
    redirect_to @post
  end

  def destroy
    @post = Post.find(params[:id])
    @comment = Comment.find(params[:id])
    if @comment.destroy
      redirect_to @post
    end
  end
end

In config/routes.rb,

QuickBlog::Application.routes.draw do
