customize auth stategy detector

[Roman Vitruk]

the private method is used for detecting auth strategies

  def detect_strategy(auth)
    strategy = auth.env["omniauth.auth"]["provider"] if auth.env["omniauth.auth"]
    strategy ||= auth.winning_strategy.class.name.split("::").last.underscore if auth.winning_strategy
    strategy ||= "database_authenticatable"
    strategy
  end

The problem appears with the device-jwt gem due to incorrect parsing.
For example, Warden::JWTAuth::Strategy transforms into strategy.

Expected result:
Warden::JWTAuth::Strategy => jwtauth_strategy
or
Warden::JWTAuth::Strategy => jwtauth

Can some custom strategy parser be added, for example, by initializer config?

Hi @skreib, you can use transform_method for this.

AuthTrail.transform_method = lambda do |data, request|
  # customize as needed
  data[:strategy] = request.env["warden"].winning_strategy.class.name
end
