Dear all,
I am a new "Ruby/Ruby on Rails" programmer. I am not sure this is the correct forum for my question. If this is not the correct forum, please indicate me a more appropriate one.
When my application implements a URL, an array, @session, is used in several methods of a first controller. The application redirects to another page, making a second controller being invoked. This controller does not use the array. When the method of the second controller ends, a layout is implicitly rendered. The layout has the following code:
...
<body>
<% if @session.length == 0 then %>
...
I got the following error message when trying to implement the URL: undefined method `length' for nil:NilClass.
What should I do in order to the array be recognized by the second controller?
Regards,
António.
