500 Internal Server Error

Question

I'm following the tutorial here: http://guides.rubyonrails.org/getting_started.html

Everything was working fine until I tried "8.1 Rendering Partial Collections" I started getting this error message:

500 Internal Server Error

If you are the administrator of this website, then please read this web application's log file and/or the web server's log file to find out what went wrong.

In the development log file I have:

<p>
  <b>Name:</b>
  ');@output_buffer.append= ( @post.name );@output_buffer.safe_concat('
');@output_buffer.safe_concat('</p>

What's wrong?

Please help.

EDIT: views/posts/show.html.erb:

<p class="notice"><%= notice %></p>
 
<p>
  <b>Name:</b>
  <%= @post.name %>
</p>
 
<p>
  <b>Title:</b>
  <%= @post.title %>
</p>
 
<p>
  <b>Content:</b>
  <%= @post.content %>
</p>
 
<h2>Comments</h2>
<%= render :partial => "comments/comment",
           :collection => @post.comments %>
 
<h2>Add a comment:</h2>
<%= render "comments/form" %>
 
<br />
 
<%= link_to 'Edit Post', edit_post_path(@post) %> |
<%= link_to 'Back to Posts', posts_path %> |

EDIT 2:

Here’s views/comments/_comment.html.erb

<p>
  <b>Commenter:</b>
  <%= comment.commenter %>
</p>
 
<p>
  <b>Comment:</b>
  <%= comment.body %>
</p>

If I remove the following the app runs:

<%= render :partial => "comments/comment",
           :collection => @post.comments %>

However, if I change the content of _comment.html.erb to blablabla it still show the same error.

Answer 1

"syntax error, unexpected tASSOC, expecting ')'"

You appear to be missing a closing parenthesis somewhere. Without seeing the surrounding code that's the best we can do.

Edit: by "surrounding code" I mean surrounding views/posts/show.html.erb:20.
