让用户 post 评论和在页面上加载评论时出错

Question

我收到以下错误：

syntax error, unexpected keyword_end, expecting end-of-input

这是我的 Comments_controller 文件，

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

    redirect_to @posts

  end

  def destroy
  end

  end
end

这是HTML使用它，

<h1><%= @post.title %></h1>

<%= @post.text %>
<h2>Comments</h2>

<% @post.comments.each do |comment| %>
    <p><%= comment.text %></p>
    <p><%= time_ago_in_words comment.created_at %> ago </p>
<% end %>

<%= form_for [@post, @post.comments.build] do |f| %>
    <p><%= f.text_area :text, :size => "40x10" %></p>
    <p><%= f.submit "Post Comment" %></p>
<% end %>

<p>
<%= link_to "Back", posts_path %>
|
<%= link_to "Edit", edit_post_path(@post) %> 
|
<%= link_to "Delete", @post, method: :delete, data: { confirm: 'Are you sure?' } %>
</p>

因此，当用户 post 的评论或当用户尝试加载评论页面时，会发生此错误。

Answer 1

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

 end
end
