Rails field not displayed in view

I have the following code in my show view.

<p>
  <strong>Average difference:</strong>
  <%= @prediction.average_difference %>
</p>

However, the field's value is not printed. What am I doing wrong?

Fire up rails console to check @prediction.average_difference if it shows up a value their in console it must show the same in the view as well.

Probably @average_difference attribute of @prediction is nil. In order to confirm that, you may write

<%= @prediction.average_difference || 'test_average_difference' %>

which should display test_average_difference.
