and has been moved to the ``AdminModel`` class in ``admin.py``. See `the

Remove ``core``
~~~~~~~~~~~~~~~
Remove the ``core`` argument from your model fields. It is no longer
necessary, since the equivalent functionality (part of :ref:`inline editing
<admin-inlines>`) is handled differently by the admin interface now. You don't
have to worry about inline editing until you get to `the admin`_ section,
below. For now, remove all references to ``core``.
Replace ``class Admin:`` with ``admin.py``

Work with file fields using the new API
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The internal implementation of :class:`django.db.models.FileField` have changed.
A visible result of this is that the way you access special attributes (URL,
filename, image size, etc) of these model fields has changed. You will need to
make the following changes, assuming your model's
:class:`~django.db.models.FileField` is called ``myfile``:
=================================== ========================
Old (0.96) New (1.0)
=================================== ========================
``myfile.get_content_filename()`` ``myfile.content.path``
``myfile.get_content_url()`` ``myfile.content.url``
``myfile.get_content_size()`` ``myfile.content.size``
``myfile.save_content_file()`` ``myfile.content.save()``
``myfile.get_content_width()`` ``myfile.content.width``
``myfile.get_content_height()`` ``myfile.content.height``
=================================== ========================
Note that the ``width`` and ``height`` attributes only make sense for
:class:`~django.db.models.ImageField` fields. More details can be found in the
:ref:`model API <ref-models-fields>` documentation.
