The latest version of Spree does this remotely - the undefined `set_preference 'method for nil: NilClass

Question

Everything works fine on my local. I installed everything correctly on the server, and when I run rake db:bootstrap or rake db:migrate , I get the following:

 rake aborted! undefined method `set_preference' for nil:NilClass /home/chrisisraw/webapps/rails/gems/gems/activesupport-3.0.5/lib/active_support/whiny_nil.rb:48:in `method_missing'

Has anyone understood this?

Answer 1

Well, it looks like in my extension I had this:

 Spree::Config.set(:stylesheets => 'screen') 

But since it was installed twice? Not sure ... but if I delete it, everything will work fine, since the "screen" is already set in the default settings.

Then I needed to make sure that I completed my migrations with the end: RAILS_ENV='production'

And we are golden!

Answer 2

You do not need to delete the initializers / initializers / whatever.rb files, just check if the spree instance exists:

 if Spree::Config.instance Spree::Config.set(:stylesheets => 'screen') end 

Answer 3

I had the same error after http://osdir.com/ml/spree-user/2009-11/msg00248.html and setting the preference to disable SSL in the initializers/prefs.rb . Removing it allowed me to complete my migration.

It was on my development machine.

Answer 4

I had the same problem with rvm. Compared to a clean gemset that really worked, the problem was that the problematic gems were BOTH in the kit and in the gem catalog. So the possible work is to create a new gemset and run the package.

Answer 5

Follow these steps:

one: Comment everything in "config / initializers / spree_config.rb"

two: run:

 bundle exec rake db:migrate 

three: Uncomment config / initializers / spree_config.rb

four: Run:

 bundle exec rake db:bootstrap
