rails3 upgrade - You provided devise_for :users but there is no model User defined in your application

[robj]

followed rails3 upgrade process as described in the railscast series,
using rails_upgrade

ruby 1.9.2 installed with RVM, Have tried both 1.2 from git , and
1.1.2 devise.
Loading the app without devise gives me

Exiting
script/rails:6: stack level too deep (SystemStackError)

raising the stack limit with ulimit doesn't help

any ideas on what may be wrong?

i tend to just put gem 'devise' in the bundle gemfile...so try that without the version number ,plus hope your ran : rails g devise User ....to ensure the model was created plus it might be a bugg in the edged version of bundle or rails

i'm getting this error too trying to upgrade a rails 2 app.

oh i had this problem and solve it but i dont remember how, as soon as i remember ill let you know

[robj]

The problem ended being the ORM needs to be explicitly required in the
devise initaliser ... I was under the impression this did not have to
be set, (as in devise1.0.x/rails2) as the initializer comments state
active record is default.

# ==> ORM configuration
# Load and configure the ORM. Supports :active_record (default)
...

require 'devise/orm/active_record'


My only issue now being (even after changing the devise initalizer
cryptor to sha1) my logins for old users are failing, new users are
fine. This is not the end of the world as my app is yet to go into
production, but im unsure why they fail.
