TemplateDoesNotExist – Erro Django

| | | |

Estou usando o Django Rest Framework. e continuo recebendo um erro

Tipo de exceção: TemplateDoesNotExist Valor da exceção: rest_framework/api.html 

Não sei como estou errando. Esta é a primeira vez que estou experimentando o REST Framework. Isso é código.

views.py

import socket, json from modules.data.models import * from modules.utils import * from rest_framework import status de rest_framework.decorators import api_view de rest_framework.response import Resposta de modules.actions.serializers import ActionSerializer @api_view(["POST"]) @check_field_exists_wrapper( "installation") def api_actions(request, format = None): action_type = request.POST["action_type"] if action_type == "Desligar" : send_message = "1" print "Desligando o sistema..." elif action_type = = "Ativar" : send_message = "1" print "Ativando o sistema..." elif action_type == "Desativar" : send_message = "1" print "Desativando o sistema..." elif action_type == "Reiniciar" : send_message = "1" print "Reiniciando o sistema..." if action_type in ["Shutdown", "Enable", "Disable"] : PORT = 6000 else : PORT = 6100 controllers_list = Controller.objects.filter (installation_id = kwargs["installation_id"]) para controller_obj em controllers_list: ip = controller_obj.ip try: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((ip, PORT)) s.send( send_message) s.close() exceto Exception as e: print("Exception when send " + action_type +" command: "+str(e)) return Response(status = status.HTTP_200_OK) 

models.py

class Controller(models.Model): id = models.IntegerField(primary_key = True) name = models.CharField(max_length = 255, unique = True) ip = models.CharField(max_length = 255, unique = True) installation_id = models.ForeignKey("Installation") 

serializers.py

de django.forms importe widgets de rest_framework importe serializadores de modules.data.models import *

class ActionSerializer(serializers.ModelSerializer): class Meta: model = Controller fields = ("id", "name", "ip", "installation_id") 

urls.py< /strong>

de django.conf.urls import patterns, url from rest_framework.urlpatterns import format_suffix_patterns urlpatterns = patterns("modules.actions.views", url(r"^$"," api_actions",name="api_actions"), )
