如何向django-filters字段添加自定义css类

Question

我试图创建一种适用于表单的方法，但这里的类不适用

class TrainerFilter(django_filters.FilterSet):
    price_lt = django_filters.NumberFilter(field_name="prise", lookup_expr='lt')
    class Meta:
        model = Profile
        fields = ['direction', 'group', 'child', 'price_lt']
        widgets = {
            'direction': SelectMultiple(attrs={'class': 'custom-select'}),     
        }

Answer 1

如果有人偶然发现了这一点，一种解决方案可能是将类添加到字段的小部件属性中，如下所示：

    class TrainerFilter(django_filters.FilterSet):

        ...

        def __init__(self, data=None, queryset=None, *, request=None, prefix=None):
            super(TrainerFilter, self).__init__(data=data, queryset=queryset, request=request, prefix=prefix)
            self.filters['direction'].field.widget.attrs.update({'class': 'custom-select'})

Answer 2

你们已经很接近了。这应该是可行的：

class TrainerFilter(django_filters.FilterSet):
    price_lt = django_filters.NumberFilter(field_name="prise", lookup_expr='lt')
    direction = django_filters.CharFilter(widgets = SelectMultiple(attrs={'class': 'custom-select'}))
    class Meta:
        model = Profile
        fields = ['group', 'child', 'price_lt']

Answer 3

class UsersFilter(django_filters.FilterSet):
class Meta:
    model = UsersModels
    fields = ['username', 'email', 'first_name', 'phone']
    filter_overrides = {
        models.CharField: {
            'filter_class': django_filters.CharFilter,
            'extra': lambda f: {
                'lookup_expr': 'icontains',
                'widget': forms.TextInput(attrs={'class': 'form-control'})
            },
        },
        models.EmailField: {
            'filter_class': django_filters.CharFilter,
            'extra': lambda f: {
                'lookup_expr': 'icontains',
                'widget': forms.EmailInput(attrs={'class': 'form-control'})
            },
        },

    }

像这样
