Fixed #19280 -- Raised an explicit exception for the old {% url %} syntax.

        view_name = self.view_name.resolve(context)

        if not view_name:

            raise TemplateSyntaxError("'url' takes requires a non-empty first"

                " argument. The syntax changed in Django 1.5, see the docs.")

        # Try to look up the URL twice: once given the view name, and again

        # relative to what we guess is the "main" app. If they both fail,

        # re-raise the NoReverseMatch unless we're using the

<topics-http-reversing-url-namespaces>`, including using any hints provided

by the context as to the current application.

.. warning::

    Don't forget to put quotes around the function path or pattern name!

    .. versionchanged:: 1.5

        The first paramater used not to be quoted, which was inconsistent with

        other template tags. Since Django 1.5, it is evaluated according to

        the usual rules: it can be a quoted string or a variable that will be

        looked up in the context.
