  message: >-
    Automatic check of the referrer for cross-site request forgery tokens has been explicitly disabled
    globally,
    which might leave views unprotected when an unsafe CSRF storage policy is used.
    Use 'pyramid.config.Configurator.set_default_csrf_options(check_origin=True)' to turn the automatic
    check for all unsafe methods (per RFC2616).
