Django Rest Framework - 具有特殊字符的查询参数

Question

我的模型是:

class Skill(models.Model):
    skill = models.CharField()

我的观点:

class SkillViewset(viewsets.ModelViewSet):
    queryset = Skill.objects.all()
    serializer_class = SkillSerializer

    filter_backends = (filters.SearchFilter, filters.OrderingFilter )
    search_fields = ('id', 'skill')
    ordering_fields = '__all__'

    def get_queryset(self):
        queryset = property_models.Skill.objects.all()
        skill = self.request.query_params.get('skill', None)
        if skill is not None:
            queryset = queryset.filter(skill__icontains=skill)
        return queryset

我的一种语言是“C++”

这个有效:

Skill.objects.filter(skill__icontains='C++')

但是调用我的 api 不起作用:

/skills/?skill=c++

Answer 1

这是因为您必须对参数进行 URL 编码，所以 c++ 变成了 c%2B%2B https://www.w3schools.com/tags/ref_urlencode.asp
