【问题描述】：

如果 get 请求接受具有字母值的 jobCategoryId，我想使用我的自定义消息创建 404 Not Found 错误响应。

请求格式：

GET /JobProfilesByCategory/:jobCategoryId

views.py：

class JobProfilesByCategoryView(generics.ListAPIView):    
"""
    A custom view to create a view for Job profile by Category. Lookup_url_kwarg fetches the jobCategoryId variable from the URL 
"""
model=JobProfiles
serializer_class = JobProfilesByCategorySerializer
lookup_url_kwarg = "jobCategoryId"

def get_queryset(self):
    jobCategoryId = self.kwargs.get(self.lookup_url_kwarg)
    print(jobCategoryId)
    if(any(c.isalpha() for c in jobCategoryId)):
        return Response("detail":"Not Found",status=status.HTTP_404_NOT_FOUND)
    else:
        queryset = JobProfiles.objects.filter(jobCategoryId=jobCategoryId)
        return queryset

urls.py:

    url(r'JobProfilesByCategory/(?P<jobCategoryId>[-\w]+$)',view=views.JobProfilesByCategoryView.as_view()),#6th API

【问题讨论】：

Django, creating a custom 500/404 error page的可能重复

【参考方案1】：

你可以使用NotFound

from rest_framework.exceptions import NotFound
...
def get_queryset(self):
    jobCategoryId = self.kwargs.get(self.lookup_url_kwarg)
    print(jobCategoryId)
    if (any(c.isalpha() for c in jobCategoryId)):
        raise NotFound("custom_key": "Custom Error Message")
    else:
        queryset = JobProfiles.objects.filter(jobCategoryId=jobCategoryId)
        return queryset
