Django 如何准确地筛选列表JSONField？

我有一个模型，基本上可以归结为：

class Model:
    json_field = JSONFIeld(default=list)

其中json_字段本质上是一个字符串列表。假设我有两个模型对象

ModelA

和

ModelB

，它们的json_字段分别为

[“1”、“2”、“3”]

和

[“1”、“2”、“4”]

如何准确地过滤到json_字段？具体而言：

搜索值是多少

按搜索值筛选的查询是什么

实际上，我正在使用来管理DRF后端的搜索功能。（例如/api/v1/models/？json\u字段=）

不幸的是，似乎没有ArrayFilter或JSONFilter，所以这就是我正在使用的：

class ModelFilter(django_filter.FilterSet):
    class Meta:
        model = Model
        field = "json_field"

    # Not even sure if this should be a CharFilter
    json_field = django_filters.CharFilter(method="json_field_filter") 

    def json_field_filter(self, queryset, name, value):
        return queryset.filter(json_field__iexact=value)
        # doesn't work where value = ["1","2","3"]
        # also doesn't work where value = "1","2","3"

我可以在网上找到字典的解决方案（我一直在上面工作），但列表却没有。如有任何帮助/指点，将不胜感激

class ModelFilter(django_filter.FilterSet):
    class Meta:
        model = Model
        field = "json_field"

    # Not even sure if this should be a CharFilter
    json_field = django_filters.CharFilter(method="json_field_filter") 

    def json_field_filter(self, queryset, name, value):
        return queryset.filter(json_field__iexact=value)
        # doesn't work where value = ["1","2","3"]
        # also doesn't work where value = "1","2","3"
