[rspec-users] class variables different between spec and runtime?
Hello Folks,
This gist http://gist.github.com/261791 has an example user.rb, user_spec.rb
At runtime, this snippet fails
u = User.find(123)
u.update_with_profile({...})
The error occurred while evaluating nil.select):
app/models/user.rb:6:in `moderator_fields''
app/models/user.rb:118:in `update_with_profile''
The spec passes all-green.
Could you tell me how this might be ?
Thanks,
Peter Fitzgibbons

In development mode, classes can get reloaded, which wipes out class (and class instance) variables. In most deployment scenarios requests from a single user might be handled by different processes, each with it''s own state. State that needs to be around between requests needs to be somewhere persistent like the DB, or the session. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale
