You’re welcome.
I’m glad my post helped you.

I’m trying to post the problems and the solutions in this blog.

Thanks. This helped me to.

I was seeing a similar NoMethodError with

@examples = example.find(:first)

in the controller, which resulted
in the following SQL (see your web server console output):

SELECT * FROM `examples` LIMIT 1

Apparently the corresponding “each” method in my views/index.html.erb file
(below) doesn’t work on a single record.

% @examples.each do |c| %>
‘show’ } %>

When I changed the contoller method to:

@examples = example.find(:all)

The LIMIT 1 was no longer in the SQL query:

SELECT * FROM `examples`

And “each” worked.

You’re welcome. It’s easy to fall into the trap hence I created this post.
