Devise: New Errors (Encrytable)

I hadn't touched my code in a week, but when I bundled, then attempted to run my webserver I now get the following errors, which are leaving me dead in the water. Including the devise-encryptable gem as suggested in the error output does not resolve the issue and still causes the same errors. Any help is greatly appreciated.

[DEVISE] Devise.apply_schema is deprecated and has no effect. Please remove it.


[DEVISE] To select a encryption which isn't bcrypt, you should use devise-encryp
table gem.


[DEVISE] Devise.use_salt_as_remember_token is deprecated and has no effect. Plea
se remove it.

[DEVISE] You're trying to include :encryptable in your model but it is not bundl

to proceed.

I just had the same problem.

As written on the wiki of devise, you have to add this line in your Gemfile:

gem 'devise-encryptable'

From the wiki:

If you're using encryptable on your models, you will now have to include devise-encryptable on your gemfile.

https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.1

Regarding the warnings:

Remove the following from your devise.rb:

# Automatically apply schema changes in tableless databases
config.apply_schema = false

# If true, uses the password salt as remember token. This should be turned
# to false if you are not using database authenticatable.
config.use_salt_as_remember_token = true
