I bumped into the following error when I was creating API program. The origin was devise gem.
NoMethodError (undefined method `failure_app’ for nil:NilClass)
- Ruby 2.2.3p173
- Rails 4.2.4
- devise 3.5.2
sign_in method for unauthorized user.
The API in construction, we have to make unauthorized user able to login, so I wrote logging in procedure for all users, including unauthorized users. Then, devise and warden rejected unauthorized user and raised error.
Write the following setting into
config.allow_unconfirmed_access_for = 2000.years
Or write the following method into the model class that is used by devise for authentication. User class for example.
I recommend latter solution.
confirmation_period_valid? method is defined at the module
Devise::Models::Confirmable of devise gem.
