Question

I got my app working so that the user can only delete their own comments but now im trying to add a link to the site but i only want the creator of the comment to be able to see the link.

I tried doing

<% if current_user %>

but when i do that it shows up on all comments and not just the user. I can do

<% if current_user.admin %> 

and that restricts only the admin to be able to see the delete links. I’ve also tried

 <% if @comment.user_id == current_user.id %>

that doesent work either. How can i do it so that the comment creator can only see the comments?

heres my view

_comments.html.erb

  <div class="container">
  <% @comments.each do |comment| %>
  <div class="comment">
<div class="gravatar_border">
  <%= gravatar_for comment.user, size: '49' %>
</div>

<div class="user_info_comments">
  <b><%= comment.user.name %></b>
  <%= comment.created_at.strftime("%b. %d  %Y") %>
</div>

<div class="user_comments">
  <%= simple_format comment.content %> 
  <%= pluralize comment.reputation_value_for(:votes).to_i, "vote" %>
  <%= link_to "", vote_comment_path(comment, type: 'up'), method: "post", class: ' icon-thumbs-up' %>
  <%= link_to "", vote_comment_path(comment, type: 'down'), method: "post", class: ' icon-thumbs-down' %>
  <% if @comment.user_id == current_user.id %>
  <%= link_to 'delete', comment, method: :delete, confirm: 'you sure?' %>
  <% end %>
   </div>
  </div>
 <% end %>
 <br />
</div>

heres my controller

comments_controller.rb

  def destroy
      @comment = Comment.find(params[:id])
      if @comment.user_id == current_user.id
        @comment.destroy
        flash[:notice] = "comment deleted!"
      else
        flash[:error] = "not allowed"
      end
   redirect_to :back
 end
