Getting "undefined method `password' for #<User:0x2b95caea8590>" with Authlogic - ruby-on-rails

Question

I realize there's a nearly identical question about this here but the fix there did not fix my problem.
My Authlogic is working in my development environment but not in my production environment. Below is the error I'm getting.

I didn't misspell any of the database columns, I'm already doing acts_as_authentic and I have restarted my server, so I'm not sure what else to try. It seems like it must be something to do with my database but my database structure seems to be identical.

Answer 1

Database password field (and/or salt field) may not match any of the defaults!!!
I've had this problem twice now and in both cases it was tricky because of two things:
1) The message "undefined method 'password' really (often) means password field not found in database using defaults.
2) The location to ADD your database field for password (or salt for that matter) is NOT anywhere in your applications directory, it in your ruby gem directory, something like ~/.gem/ruby/1.8/gems/authlogic-2.1.6/lib/authlogic/acts_as_authentic !
The field to change is password.rb. Add your field name(s) in to the list, e.g. i added pd_hashed changed:
module Config
# The name of the crypted_password field in the database.
#
# * Default: :crypted_password, :encrypted_password, :password_hash, or :pw_hash
# * Accepts: Symbol
def crypted_password_field(value = nil)
rw_config(:crypted_password_field, value, first_column_to_exist(nil, :pd_hashed, :crypted_password, :encrypted_password, :password_hash, :pw_hash))
end
Do the same for the salt field.
Restart and this may help.
