Hi all,

I get a really strange error… I have 2 simple models:

class Membre \< ActiveRecord::Base  
has\_one :adhesion  
end

class Adhesion \< ActiveRecord::Base  
belongs\_to :membre  
end

The relation works well in the console. I can find a Membre and get  
its Adhesion, or find an Adhesion and get the Member.

Now in a controler/view… If I find like this:

@adhesion = Adhesion.find\_by\_membre\_id(id)

I can use @adhesion in the view without any problem.

But if I do:  
@adhesion = Membre.find(id).adhesion (what is more clean and logical)

I get an error in the view, as soon as I try to read any field/method  
of @adhesion.

What confuses me is that in both cases, the content of @adhesion is  
the same in the view:

#\<Adhesion id: 1, membre\_id: 51, type: nil, date\_adhesion: nil,  
date\_expiration: nil, created\_at: “2009-01-06 14:21:06”, updated\_at:  
“2009-01-06 14:21:06”\>

#\<Adhesion id: 1, membre\_id: 51, type: nil, date\_adhesion: nil,  
date\_expiration: nil, created\_at: “2009-01-06 14:21:06”, updated\_at:  
“2009-01-06 14:21:06”\>

The failing view:

\<%= @adhesion.inspect %\>  
\<%=  
if @adhesion.date\_adhesion.nil? # line 9 is here #  
“You don’t have adhesion.”  
%\>

The error:  
You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occurred while evaluating nil.include?

Any idea welcome!

Read you,

Well, sorry to make noise! The solution is here:  
[http://www.railsformers.com/article/activerecord-timezone-settings-bug](http://www.railsformers.com/article/activerecord-timezone-settings-bug)

It seems to be a bug. I just added

config.active\_record.default\_timezone = :utc

in my env.rb…
