search_fields 和 FilterSet

第一种方法

    search_fields = ['code', 'name', 'short_name', 'org_type', 'trade_status', 'address', 'search']  # search 字段模糊搜索

第二种方法

from django_filters.rest_framework import FilterSet
import django_filters, json, re

class FilterIMChatToGroupMessage(FilterSet):
    im_session = django_filters.CharFilter(field_name="im_chat_to_group__session_id", method='filter_im_session')

    def filter_im_session(self, queryset, name, value):
        nid = self.request.GET.get("im_session")
        if IMChatToGroupMessage.objects.filter(from_to_user=self.request.user,
                                               im_chat_to_group__im_session__session_id=nid, is_read=True).count():
            # 出于性能考虑先求总数
            IMChatToGroupMessage.objects.filter(from_to_user=self.request.user,
                                                im_chat_to_group__im_session__session_id=nid, is_read=True).update(
                is_read=False)
        return queryset.filter(from_to_user=self.request.user, im_chat_to_group__im_session__session_id=nid)

    class Meta:
        model = IMChatToGroupMessage
        fields = ["im_session"]
