No route found for omniauth developer strategy

Question

I've just updated Omniauth from 0.2.6 to 1.1.1 in order to use the developer strategy. I've made my login link point to /auth/developer if the environment is development and /auth/facebook if production.

The Facebook strategy still works. When using the developer strategy, the link goes to the built-in Omniauth sign in page but returns a 404 when clicking sign in. This model does not use Devise.

Routes file

get "/auth/:provider/callback" => "sessions#create"
.
.
.
get '*a', :to => 'errors#routing'

Omniauth initializer

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, [etc.]
  provider :developer if Rails.env.development?
end

ActionController::RoutingError (No route matches "/auth/developer/callback")

Answer 1

Ran into this today in a new rails 4 application, I'm currently using this route as a workaround:

match '/auth/:provider/callback', to: "sessions#create", via: [:get, :post]
