Spree 's latest version does this on remote - undefined method `set_preference' for nil:NilClass

Question

Everything works perfect on my local. I installed everything appropriately on the server, and when I run rake db:bootstrap or rake db:migrate, I get this :

rake aborted!
undefined method `set_preference' for nil:NilClass

Anyone figure this out?

Answer 1

You don't have to remove your initializers files initializers/whatever.rb, just test whether spree instance exists :

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

Answer 2

Ok it looks like in my extension I had this:

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

But since this was set twice? Not sure.. but if I deleted it, everything works perfectly since 'screen' is already set in the default preferences.

Then I had to make sure I ran my migrations with the ending : RAILS_ENV='production'

And we're golden!
