nil object in create_time_zone_conversion_attribute?

Happily coding away in a Rails 2.2.2 Bort based-app, when I suddenly
start getting this error after a few requests:

NoMethodError (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?):
    /opt/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/
active_record/attribute_methods.rb:142:in
`create_time_zone_conversion_attribute?''
    /opt/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/
active_record/attribute_methods.rb:75:in `define_attribute_methods''

This only appears if I authenticate to the application.  I can make a
couple of requests, then i start getting the above error.  While I
don''t think I''ve made any changes to cause something like
this, when
you''re so far removed from the low-level bits of the framework,
it''s
hard to tell.

I''ve searched the net, and while I''ve found a few hits on
this, there
are no solutions to be found.

Anyone have any suggestions?

Re: nil object in create_time_zone_conversion_attribute?

Some further information....

This issue is apparently caused by not passing enough parameters to
the route helpers when you have nested resources.  For example, I have
a gallery, which has a nested image resource.  When generating links
in the view, I called the helper, but I didn''t pass an array with both
the gallery and the image, only the image.

The first time presenting the view would work; the second, I would get
the stack trace, and from that point on the mongrel instance is
hooped, and would not serve any content.  It would have to be
restarted.

I''ve fixed the view, and the problem is now resolved.

However, I''m concerned about being able to crash mongrel hard this
way.....

I was getting similar errors I started using Rails.cache w/ Rails 2.2.2. 
I''m
using Webrick, not Mongrel.  I gave up and went back to using my homegrown
caching.  With you information about not enough parameters, I may go back and
try again.

I went back and looked hard at my code that was crashing.  I was missing a
parameter to a yield statement.  So Rails appears to be brittle around this
issue.  And maybe Mongrel more brittle than Webrick.

Thanks for the hint.  It is always nice to get rid of code that I have to
maintain in favor of builtin stuff that someone else maintains.

Re: nil object in create_time_zone_conversion_attribute?

I just ran into this problem in an action that had nothing to do with
a view (the action was just rendering a status code).

Any chance you are assigning an AR class to a variable, and then
calling methods on that variable like so:

saved_class = User  # User is AR
saved_class.create(whatever)

When I changed that to this:

saved_class = :User
Object.const_get(saved_class).create(whatever)

everyone was happy.


I''ve love to track down why this is happening in my case -- but no
time.  Plus, that''s the way thoughtbot does it in factory_girl, so
it''s gotta be right :-)

Good luck.

Re: nil object in create_time_zone_conversion_attribute?

I''m getting the same error and a bit baffled.

For me it''s happening when I''ve cached an array of
ActiveRecord objects
with Rails.cache and try to read them back. If I''m dealing with an
array
of integers it works fine.

Note that this is only happening on my development machine with whatever 
Rails'' default caching mechanism is. In production, with Memcached,
it''s
fine, so I just ended up installing Memcached on my development machine 
and it worked fine.

That was exactly my experience, except that I''m a bit of a n00b with
RoR
(though not other development) and figured I must be doing something 
wrong. Hours and hours later I finally realized that, no, Rails.cache in 
2.2.2 (at least) is failing to either store or retrieve ActiveRecord 
objects.

Five minutes after reading this I had memcached installed locally and 
all my problems were solved.

I had the same problem, and same solution.  But I just recently upgraded 
to 2.3.2 and everything seems to work fine.  I suppose whatever it was 
got fixed?

I just upgraded to 2.3.2 on Windows 7 and am getting the error.  Using 
file system gives a different error Unable to create directory, and 
memcached won''t install.  Not sure what to do.

I''ve seen this problem in 2.3.2 and now in 2.3.3.  The above mentioned
solution does not resolve this issue for me.

Either of you filed a bug report?  With a sandbox app and tests?
