[RUBY] I want to display the name of the poster of the comment

I want to display the name of the poster of the comment in the comment list when the three relations of User, Post, and Comment are as follows.


has_many :posts
has_many :comments


belongs_to :user
fas_many :comments


belongs_to :user
belongs_to :post


<p>List of comments</p>
<% @comments.each do |c| %>
    <a href="/users/#{c.user_id}"><%= c.user.name %></a>
    <%= c.content %>
<% end %>

Since the name of c.user.name becomes NoMethodError, the user information related to comment can be incorporated by adding the following line to posts.controller.


def show
   @comments = @post.comments.includes(:user).all
