Instance Method Details

#matches?(request) ⇒ Boolean

Returns true if this request's +:page_glob+ parameter is a valid Cadmus page glob, false if it's not. Allows +:page_glob+ to be nil only if the Rails environment is +test+, because +assert_recognizes+ doesn't always pass the full params hash including globbed parameters.

Parameters:

  • request —

    an HTTP request object.

Returns:

  • (Boolean) —

    true if this request's +:page_glob+ parameter is a valid Cadmus page glob, false if it's not. Allows +:page_glob+ to be nil only if the Rails environment is +test+, because +assert_recognizes+ doesn't always pass the full params hash including globbed parameters.
