每当应用搜索时，增加模型的计数字段 [英] Increasing the count field of model whenever a search is applied

问题描述

我有一个搜索API

   class SearchViewSet(RetrieveModelViewSet):
        serializer_class = ArticleSerializer
        queryset = Article.objects.all()
        query = self.request.query_params.get("query")

        final_queryset = search(query,queryset,#some logic)

        #logic to generate serialiser and return serialiser.data
        serialiser = self.get_serializer(final_ueryset, many=True)

search 函数返回文章列表，即

search function returns a list of articles i.e

   type(final_queryset) is List

然后。我也不会退回商品order_by（’count）。
现在，我不想增加final_queryset中排名前3的文章的计数了。

And. I wan't to return the articles order_by('count) as well. Now I wan't to increase the count of top 3 articles from the final_queryset is there a way of doing this.

推荐答案

想出了一种实现此
的方法，只需在列表上进行迭代并增加 count 列表中的对象

Figured out a way for doing this Just simply iterate on the list and increment the count of the objects in the list

   class SearchViewSet(RetrieveModelViewSet):
        serializer_class = ArticleSerializer
        queryset = Article.objects.all()
        query = self.request.query_params.get("query")

        final_queryset = search(query,queryset,#some logic)

        # to increment the count of top 3 entity_aliases
        for instance in final_queryset[:3]:
            instance.count += 1
            instance.save()

        #logic to generate serialiser and return serialiser.data
        serialiser = self.get_serializer(final_ueryset, many=True)
