yesterday I've udpated my spree version 1.2.0 to 1.2.3. It was very easy.
Just update my Gemfile to new versions, bundle update, install new
migrations and rake db:migrate. And its done.
But now spree/rails doesnt find a lot of standard paths:
there are errors like: undefined local variable or method
`new_user_session_path' for #<#<Class:0x007f9719a0a9f8>:0x007f971d901ff8>
If I comment out these files in my haml files, than spree started up. Other
paths are working.
rake:routes are looking good, the routes are here. For example:
new_user_session GET /user/sign_in(.:format)
