Strange error...

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, Jej

Well, sorry to make noise! The solution is here: 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...
