hello,

i'm newbie of rubby an rails.
i'm using ruby version 1.8.7 and rails version 2.3.2.

I just downloaded this sample source code and tried to use.

I got this error

NoMethodError in Articles#index

Showing app/views/articles/index.html.erb where line #12 raised:

You have a nil object when you didn't expect it!
The error occurred while evaluating nil.strftime

Extracted source (around line #12):

9:
10: <% calendar_for @articles, :year => @date.year, :month => @date.month do |calendar| %>
11: <%= calendar.head('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday') %>
12: <% calendar.day(:day_method => :published_on) do |date, articles| %>
13: <%= date.day %>
14:
15: <% for article in articles %>
