.. templatefilter:: fix_ampersands

fix_ampersands

^^^^^^^^^^^^^^

.. note::

    This is rarely useful as ampersands are automatically escaped. See

    :tfilter:`escape` for more information.

.. deprecated:: 1.7

    This filter has been deprecated and will be removed in Django 1.8.

Replaces ampersands with ``&`` entities.

For example::

    {{ value|fix_ampersands }}

If ``value`` is ``Tom & Jerry``, the output will be ``Tom & Jerry``.

However, ampersands used in named entities and numeric character references

will not be replaced. For example, if ``value`` is ``Café``, the output

will *not* be ``Café`` but remain ``Café``. This means that

in some edge cases, such as acronyms followed by semicolons, this filter will

not replace ampersands that need replacing. For example, if ``value`` is

``Contact the R&D;``, the output will remain unchanged because ``&D;``

resembles a named entity.
