Converts URLs in plain text into clickable links. Converts URLs in text into clickable links.
Note that if ``urlize`` is applied to text that already contains HTML markup, Works on links beginning with ``http://``, ``https://``, or ``www.`` and
things won't work as expected. Apply this filter only to *plain* text. ending with ``.org``, ``.net`` or ``.com``. Links can have trailing punctuation
(periods, commas, close-parens) and leading punctuation (opening parens) and
``urlize`` will still do the right thing.
Links generated by ``urlize`` have a ``rel="nofollow"`` attribute added
to them.
For example:: For example::
{{ value|urlize }} {{ value|urlize }}
If ``value`` is ``"Check out www.djangoproject.com"``, the output will be If ``value`` is ``"Check out www.djangoproject.com"``, the output will be
``"Check out <a ``"Check out <a href="http://www.djangoproject.com"
href="http://www.djangoproject.com">www.djangoproject.com</a>"``. rel="nofollow">www.djangoproject.com</a>"``.
The ``urlize`` filter also takes an optional parameter ``autoescape``. If
``autoescape`` is ``True``, the link text and URLs will be escaped using
Django's built-in :tfilter:`escape` filter. The default value for
``autoescape`` is ``True``.
.. note::
If ``urlize`` is applied to text that already contains HTML markup,
things won't work as expected. Apply this filter only to plain text.
