Sequel::Devise

Allows the usage of a Sequel::Model class as a Devise mapping.

This gem was previously developed at rosenfeld/sequel-devise.

Add this line to your application's Gemfile:

gem 'sequel-devise'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sequel-devise

class User < Sequel::Model
    plugin :devise
    devise :database_authenticatable
end

If you're interested in more instructions on using Sequel with Rails, I've written some instructions in my web site.

Unfortunately Devise does not rely on the orm_adapter specs as it was supposed to.

It will assume the model support other methods besides those defined by orm_adapter and that they behave like the equivalent in ActiveRecord supporting the same arguments.

In some cases, it will call some method which is not defined by Sequel::Model, so we implement them in this gem, but there are some cases which are trickier. For example, Devise will call the save method in the model and expect it to return false if the validation fails. This is not the default behavior of Sequel::Model, so you'll have to change this behavior for your User classes that are intended to be used by Devise. There are a few solutions depending on your use case:

Please make sure you take a look at the implementation to understand which methods are added in order to support Devise. Particularly, for security reasons Devise will override inspect so that it doesn't display passwords hashes for example among other keys. If you want the original inspect, call user.inspect(false).

Just disable the raise behavior by default:

Sequel::Model.raise_on_save_failure = false

class User < Sequel::Model
  self.raise_on_save_failure = false
  plugin :devise
  devise :database_authenticatable
end

You are free to simply create another user class that is meant to be used by Devise while the remaining of your application just use your regular user class:

class DeviseUser < User
  self.raise_on_save_failure = false
  plugin :devise
  devise :database_authenticatable
end

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

Thanks to @rosenfeld for creating this gem before we started maintaining it!
