Ar - rollback on staging/production - whats causing it?

hi,

i;m using a easy feedback plugin which works just fine - locally.

uploading the app to staging production gives me this:

/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:214:in
rollback_active_record_state!' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:196:insave’
/home/tom/ror/fooapp.com/staging/releases/20110517122608/app/controllers/feedbacks_controller.rb:21:in
`create’

the create method is basically this:

def create
@feedback = Feedback.new(params[:feedback])
if logged_in?
@feedback.user_id = current_user.id
end

if @feedback.valid?
    FeedbackMailer.deliver_feedback(@feedback) if 

!@feedback.email.blank?
@feedback.save
render :status => :created, :text => ‘

Thank you for your
feedback!


else
@error_message = “Please enter your
#{@feedback.subject.to_s.downcase}”
render :action => ‘new’, :status => :unprocessable_entity
end

end

validation is only on one field, which has a value in the params-hash.
model-validations etc are all the same - locally vs server

any ideas?

Well, that’s the top of the stack-trace but the actual exception and its
message is?

Well, since the code in your action looks simple enough and since we
know
the error is raised on the @feedback.save call, then I’d focus on why it
can’t save. The upshot is that we need more info to help you. What were
the
values submitted to the action (in the params hash) by the request that
failed? What was the actual exception and error message (it’s nice you
provided stack trace but we need this too). What is this validation’s
code,
the one you said the model has “on one field”? What else might be
different
in your environment between your development and staging production?
Does it
succeed in production mode on your dev workstation, meaning the problem
is
specific to where it’s deployed, not the mode? Or, does it always fail
in
production, regardless of where it’s deployed?

Etc.

hi,

here are the missing info:

The clue is in the error message. At the above line you are
presumably calling delete, though that seems a bit odd in create. The
object you are calling delete on is nil.

hi

think the best is to use debugger and see what happening here

yes and no - im not calling delete ‘manually’ nor do i have coded it
into the create method. to me it seems the rollback is doing this, as
far as i can trace back the code.
anyhow - thx
