  self.content_type = request.format.to_s
  self.response_body = http_auth_body
end

#http_auth? ⇒ Boolean (protected)

Choose whether we should respond in a http authentication fashion, including 401 and optional headers.

This method allows the user to explicitly disable http authentication on ajax requests in case they want to redirect on failures instead of handling the errors on their own. This is useful in case your ajax API is the same as your public API and uses a format like JSON (so you cannot mark JSON as a navigational format).

Returns:

  • (Boolean)

#store_location! ⇒ Object (protected)

Stores requested uri to redirect the user after signing in. We cannot use scoped session provided by warden here, since the user is not authenticated yet, but we still need to store the uri based on scope, so different scopes would never use the same uri to redirect.
