在django-filter中的numericFilter中添加选择

Question

这是我的过滤器

class RiderFilter(django_filters.FilterSet):
    cost_gt = django_filters.NumberFilter(label='Costo maggiore di',lookup_expr='cost__gt')
    cost_lt = django_filters.NumberFilter(label='Costo minore di',lookup_expr='cost__lt')
    class Meta:
        model = Rider
        fields = [ ]

如何为我的cost_gt和cost_lt添加一些特定的选择？

Answer 1

您应该可以使用ChoiceFilter。

class RiderFilter(django_filters.FilterSet):
    cost_gt = django_filters.ChoiceFilter(
        label='Costo maggiore di',
        field_name='cost', lookup_expr='gt', 
        choices=[(1, '1'), (2, '2'), (3, '3')],
    )
    cost_lt = django_filters.NumberFilter(
        label='Costo minore di',
         field_name='cost', lookup_expr='lt', 
         choices=[(4, '4'), (5, '5'), (6, '6')],
    )
