No description provided.

Well I did not actually test the method ... Apparently it's not accessible:

NoMethodError: undefined method `valid_password?' for #<User:0x00000009ea27d0>

Why is that ?

[arnvald]

@jerefrer are you sure you've called authenticates_with_sorcery! in User class?

[jerefrer]

@arnvald Yes definitely

There must be something wrong, either in your project, or maybe it's a problem specific to some configuration (new/old version of Rails etc). I've just run it and it works:

λ ARV sorcery-example-app → λ git rails_4* → bundle exec rails c
Loading development environment (Rails 4.0.2)
irb(main):001:0> User.new.valid_password?('a')
=> false

This is weird indeed.
Activated submodules are :remember_me and :activity_logging
I tried removing every other gem in the project and the bug is still there, but in case you'd want to take a look here are my Gemfile and Gemfile.lock: https://gist.github.com/jerefrer/69700ea146fcd2590969

@arnvald I updated my Gemfile to fetch sorcery from github, and now the issue is gone, valid_password? is working as expected. Before updating active_for_authentication? was also not working (not called when authenticating).

Maybe it would be time to push a new version to rubygems ? (and merge my PR ;)

Thanks 👍

Have a great day !
