ActionView::Template::Error (Model User does not respond to password):

After upgrading rails from 3.0.0 to 3.0.1 and passenger to 3.0 I am getting this error in production:

ActionView::Template::Error (Model User does 开发者_JS百科not respond to password):
23:
24: <p>
25:     <%= f.label :password %><br />
26:     <%= f.password_field :password %>
27:   </p>
28: <p>
29:     <%= f.label :password_confirmation %><br />
app/views/users/new.html.erb:26:in `_app_views_users_new_html_erb___104064734$

In development this page works fine but with some deprecation warnings:

I ran into a similar error when testing my application on heroku. For me, the fix was as simple as updating my rails gem to the latest 3.0.3 (I am also using authlogic from a git source). I.e. my Gemfile contains the following:

gem 'rails', '3.0.3'
gem 'authlogic', :git => 'git://github.com/odorcicd/authlogic.git', :branch => 'rails3'

I then ran:

bundle update

To rebuild my snapshot from scratch, and this resolved the (Model does not respond to password) error that I was getting.

Hope this fixes your similar problem as well.
