undefined method 'answers' for nil:NilClass #316

Closed mjthompsgb closed 12 years ago

mjthompsgb commented 12 years ago

I get the error "undefined method 'answers' for nil:NilClass" when trying to run "rake surveyor FILE=surveys/kitchen_sink_survey.rb" . I previously had this working on a different rails app but for some reason it won't work on this app. Everything is identical except it is just a fresh install of the server. I have searched and searched to find an answer with no luck. Please help me figure this out.

Thanks Matt

Can you verify some information on your environment? Specifically: surveyor gem version, rails version, ruby version, and OS you're deploying too (or deployment platform if you're using Heroku/Engine Yard, etc.)?

Also, does the entire survey import, or does it stop on a particular question? When you do the import it outputs the questions/answers to the command line, and the last one that shows up is where the import process choked.

Hi Matt,

Which version of surveyor/rails/ruby are you using? Also, can you run rake surveyor FILE=surveys/kitchen_sink_survey.rb --trace and post the full backtrace?

Thanks, John

Thanks for getting back to me so quickly. I should of known to put that stuff in after reading all the other issues I read but forgot.

Surveyor version: 0.22.0 Rails version: 3.1.4 Ruby version: 1.9.2 OS: Red Hat Enterprise Linux Server release 6.2 (Santiago)

I am running Rails on Nginx server with Unicorn. I am also using RVM.

It has an undefined method error for any survey I attempt to import but here is the exact output of running the import on the default kitchen_sink_survey that comes with Surveyor.

The error is essentially the same for any survey I try to import but the undefined method is different for each.

Let me know if you need any more info or want me to try something.

Thanks again. Matt

It appears to be aborting at the spot in the survey file where Grids are used. Line 161 or around there.

mjthompsgb commented 12 years ago

I am not sure what was wrong with my previous server setup and the Surveyor install but I reinstalled everything that had to do with RoR and reinstalled Surveyor and now it works. Wasn't a surveyor issue though so that is good. Thanks for taking anytime you did to look into it though.

Thanks Matt
