    The descriptor for the file attribute on the model instance. Return a
    FieldFile when accessed so you can write code like::

        >>> from myapp.models import MyModel
        >>> instance = MyModel.objects.get(pk=1)
        >>> instance.file.size

    Assign a file object on assignment so you can do::

        >>> with open('/path/to/hello.world') as f:
        ...     instance.file = File(f)

        Update field's width and height fields, if defined.

        This method is hooked up to model's post_init signal to update
        dimensions after instantiating a model instance.  However, dimensions
        won't be updated if the dimensions fields are already populated.  This
        avoids unnecessary recalculation when loading an object from the
        database.

        Dimensions can be forced to update with force=True, which is how
        ImageFileDescriptor.__set__ calls this method.
