Comment section not displaying - ruby-on-rails

Question

I am working on my first rails application and I am attempting to add a comment section. The comments will fall under each topic. I am seeing comments that are being generated but I am not able to get it configured so that I can input my own comments. I will list below the changes I have made to my code as instructed by my assignment.
Heres a change to my app/models/comment.rb
class Comment < ActiveRecord::Base
belongs_to :post
belongs_to :user
validates :body, length: { minimum: 5 }
validates :body, presence: true
validates :user_id, presence: true
end
Heres my app/models/user.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable
has_many :posts
has_many :comments
mount_uploader :avatar, AvatarUploader
def admin?
role == 'admin'
end
def moderator?
role == 'moderator'
end
end
I have to also update db/seeds.rb
# Create Comments
100.times do
Comment.create!(
# user: users.sample, # we have not yet associated Users with Comments
post: posts.sample,
user: users.sample,
body: Faker::Lorem.paragraph
)
end
Updated my config/routes.rb
resources :comments, only: [:create]
Updated my app/controllers/comments_controller.rb
class CommentsController < ApplicationController
def create
#post = Post.find(params[:post_id])
#comment = current_user.comments.new(comment_params)
#comment.post = #post
#new_comment = Comment.new
authorize #comment
end
end
The final adjustments I made was to app/views/comments/_form.html.erb
<% if current_user %>
<h4>Add a comment:</h4>
<%= form_for [#post, #post.comments.build], remote: true do |f| %>
<%= f.label :body %>
<%= f.text_field :body %>
<%= f.submit %>
<% end %>
<% end %>
I hope that this is sufficient enough for some type of a response as to what I may be missing. I do not get an error, the box that I am looking for to create a comment just does not appear. Here is an example of what I am trying to accomplish:

edit:
Here is the app/views/posts/show.html.erb
<h1><%= markdown #post.title %></h1>
<div class="row">
<div class="col-md-8">
<small>
<%= image_tag(#post.user.avatar.tiny.url) if #post.user.avatar? %>
submitted <%= time_ago_in_words(#post.created_at) %> ago by
<%= #post.user.name %>
</small>
<p><%= markdown #post.body %></p>
<p><%= image_tag(#post.image_url) if #post.image? %></p>
</div>
<div class="col-md-4">
<% if policy(#post).edit? %>
<%= link_to "Edit", edit_topic_post_path(#topic, #post), class: 'btn btn-success' %>
<% end %>
</div>
</div>
