Question

I have the following code that should show the value for the display field in my view:

<% @product.options.each do |o| %>
<tr>
    <td class="option"> 
    <%= o.display %> 
    ...

But the o.display part doesn’t work for the very first option record. On all other options, it correctly prints the display value, but not on the very first one. I have verified in MySQL that a value exists for that particular option (Option 1):

mysql> select id,title,display from options;
+----+-----------------------------+---------+
| id | title                       | display |
+----+-----------------------------+---------+
|  1 | Option 1                    |       1 |
|  2 | Option 2                    |       2 |
|  3 | Option 3                    |       3 |
+----+-----------------------------+---------+

What am I doing wrong here?

More info:

If I add:

<%= debug o %>

before trying to print the display field, it not only shows debug information, but shows the display value properly. With no debugging, it won’t show the display value.

Answer 1

display is a method of the Object class in Ruby and this created a problem with ActiveRecord I guess. Maybe you could change the name of that field, it should be the simpler option.
