put方法不适用于RetrieveUpdatedStroyapiView Django Rest框架
我试图在django rest框架中发出put请求。我的视图是从RetrieveUpdatedStroyapiView类继承的 我使用的前端django休息的后端角度 以下是错误:put方法不适用于RetrieveUpdatedStroyapiView Django Rest框架,django,django-rest-framework,put,http-error,django-generic-views,Django,Django Rest Framework,Put,Http Error,Django Generic Views,我试图在django rest框架中发出put请求。我的视图是从RetrieveUpdatedStroyapiView类继承的 我使用的前端django休息的后端角度 以下是错误: Failed to load resource: the server responded with a status of 405 (Method Not Allowed) ERROR detail:"Method "PUT" not allowed." 下面是从angular端到django rest的put

下面是从angular端到django rest的put请求的完整实现
editcity(index){
this.oldcityname = this.cities[index].city;
const payload = {
citypk: this.cities[index].pk,
cityname: this.editcityform.form.value.editcityinput
};
this.suitsettingsservice.editcity(payload, payload.citypk)
.subscribe(
(req: any)=>{
this.cities[index].city = req.city;
this.editcitysucess = true;
// will have changed
this.newcityname = this.cities[index].city;
}
);
}
正在呼叫的服务
editcity(body, pk){
const url = suitsettingscity + '/' + pk;
return this.http.put(url, body);
要映射到django端的url:
url(r'^city/(?P<pk>[0-9]+)',SearchCityDetail.as_view())
RetrieveUpdatedStoryApiView文档:
RetrieveUpdatedStroyapiView
用于读写删除端点以表示单个模型实例
提供get、put、patch和delete方法处理程序
扩展:GenericAPIView、RetrieveModelMixin、UpdateModelMixin、DestroyModelMixin
RetrieveUpdatedStroyapiView源代码:
class RetrieveUpdateDestroyAPIView(mixins.RetrieveModelMixin,
mixins.UpdateModelMixin,
mixins.DestroyModelMixin,
GenericAPIView):
"""
Concrete view for retrieving, updating or deleting a model instance.
"""
def get(self, request, *args, **kwargs):
return self.retrieve(request, *args, **kwargs)
def put(self, request, *args, **kwargs):
return self.update(request, *args, **kwargs)
def patch(self, request, *args, **kwargs):
return self.partial_update(request, *args, **kwargs)
def delete(self, request, *args, **kwargs):
return self.destroy(request, *args, **kwargs)
您的
SearchCityListCreate
的URL模式与/city/x/
匹配,因此您的请求被错误的视图处理
您通过切换顺序解决了这个问题,但更好的解决方法是确保您的正则表达式有^
和$
分别标记URL的开始和结束
url(r'^city$', SearchCityListCreate.as_view()),
url(r'^city/(?P<pk>[0-9]+)$',SearchCityDetail.as_view()),
url(r'^city$,SearchCityListCreate.as_view()),
url(r“^city/(?P[0-9]+)$”,SearchCityDetail.as_view()),
我需要颠倒城市URL的顺序
事实上,带有pk的城市url从未被使用过
坏的:
url(r'city',SearchCityListCreate.as_view()),#创建城市列表url
url(r'city/(?P[0-9]+)/$,SearchCityDetail.as_view()),
好:
url(r'city/(?P<pk>[0-9]+)/$',SearchCityDetail.as_view()),
url(r'city', SearchCityListCreate.as_view()), # create city list url
url(r'city/(?P[0-9]+)/$”,SearchCityDetail.as_view(),
url(r'city',SearchCityListCreate.as_view()),35;创建城市列表url
您可以使用rest\u框架类视图`类国家/地区详细信息(APIView)来实现它:
def get_对象(自身,主键):
尝试:
返回CountryModel.objects.get(pk=pk)
除CountryModel.DoesNotExist外:
提高Http404
def get(self,request,pk,format=None):
country=self.get_object(pk)
serializer=CountrySerializer(country)
return Response(serializer.data,status=status.HTTP_200_OK)
def put(self,request,pk,format=None):
country=self.get_object(pk)
serializer=CountrySerializer(country,data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data,status=status.HTTP_200_OK)
return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
def delete(self,request,pk,format=None):
country=self.get_object(pk)
country.delete()`
也许您有一个冲突的URL模式,请求没有被
SearchCityDetail
@Alasdair处理,这是一个很好的想法,我将对此进行研究it@Alasdair所以这两个url模式以相反的方式出现在现在的位置。我遇到了一个连接被拒绝的问题,但我会解决这个问题,我认为我们可能会很好地url(r'city/(?P[0-9]+)/$),SearchCityDetail.as#view())\detele put get url url(r'city',SearchCityListCreate.as#view()),#创建城市列表url
@Alasdair。它起作用了Hanks@Alasdair我现在就做这些改变
url(r'city/(?P<pk>[0-9]+)/$',SearchCityDetail.as_view()),
url(r'city', SearchCityListCreate.as_view()), # create city list url
def get(self,request,pk,format=None):
country=self.get_object(pk)
serializer=CountrySerializer(country)
return Response(serializer.data,status=status.HTTP_200_OK)
def put(self,request,pk,format=None):
country=self.get_object(pk)
serializer=CountrySerializer(country,data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data,status=status.HTTP_200_OK)
return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
def delete(self,request,pk,format=None):
country=self.get_object(pk)
country.delete()`
