[解決済み] TemplateDoesNotExist - Djangoエラー

質問

Django Rest Framework を使っているのですが、エラーが出続けます。

Exception Type: TemplateDoesNotExist
Exception Value: rest_framework/api.html

私はどのように間違っているのか分からない。これは、私がRESTフレームワークに手を出すのは初めてのことです。 これはコードです。

views.py

import socket, json
from modules.data.models import *
from modules.utils import *
from rest_framework import status
from rest_framework.decorators import api_view
from rest_framework.response import Response
from 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 == "Shutdown" : 
        send_message = '1'
        print "Shutting Down the system..."
    elif action_type == "Enable" : 
        send_message = '1'
        print "Enabling the system..."
    elif action_type == "Disable" : 
        send_message = '1'
        print "Disabling the system..."
    elif action_type == "Restart" : 
        send_message = '1'
        print "Restarting the system..."

    if action_type in ["Shutdown", "Enable", "Disable"] : PORT = 6000
    else : PORT = 6100

    controllers_list = Controller.objects.filter(installation_id = kwargs['installation_id'])

    for controller_obj in 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()
        except Exception as e:
            print("Exception when sending " + 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')

シリアライザー.py

from django.forms import widgets from rest_framework import serializers from modules.data.models import *.

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

urls.py

from 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'),
)

どのように解決するのですか？

まず rest_framework にリストされていることを確認してください。 settings.py INSTALLED_APPS .
