Tengo un proyecto recientemente iniciado donde estoy usando mongoid para la base de datos y rails_admin para administrarlo, ahora quiero tener una API y he elegido rails-api para hacerlo, pero por alguna razón, ya que acaba de agregar carriles-api en el fichero de gema, no puedo acceder a la administración y estoy consiguiendo este errorrails_admin con el conflicto rails-api
