    field_config={
        'status': {
            'widget': 'select',

FloatField, DecimalField	double	equal, not_equal, less, less_or_equal, greater, greater_or_equal, between, is_null, is_not_null
BooleanField	boolean	equal
DateField	date	equal, not_equal, less, less_or_equal, greater, greater_or_equal, between, is_null, is_not_null
DateTimeField	datetime	equal, not_equal, less, less_or_equal, greater, greater_or_equal, between, is_null, is_not_null
TimeField	time	equal, not_equal, less, less_or_equal, greater, greater_or_equal, between
ForeignKey, OneToOneField	integer	equal, not_equal, less, less_or_equal, greater, greater_or_equal, between, is_null, is_not_null
