I use Django along with Django REST Framework to implement a RESTful API.
What I have right now:
ContentEntry
modelContentEntryCreateUpdateSerializer
serializer for my ContentEntry
modelContentEntryCreate
view to create some ContentEntry
ies
ContentEntryUpdate
view to update the ContentEntry
ies
Here is the code:
from django.db import models
from rest_framework import serializers
from rest_framework import generics
from rest_framework.views import APIView
from my_api_app import views
# models.py
class ContentEntry(models.Model):
content = models.ForeignKey(Content)
quantity = models.IntegerField()
container = models.ForeignKey(Container, related_name='content_entries')
# serializers.py
class ContentEntryCreateUpdateSerializer(serializers.ModelSerializer):
class Meta:
model = ContentEntry
fields = ('id', 'content', 'quantity', 'container')
# views.py
class ContentEntryCreate(generics.CreateAPIView):
queryset = ContentEntry.objects.all()
serializer_class = ContentEntryCreateUpdateSerializer
# views.py
class ContentEntryUpdate(generics.UpdateAPIView):
queryset = ContentEntry.objects.all()
lookup_field = 'id'
serializer_class = ContentEntryCreateUpdateSerializer
# urls.py
urlpatterns = [
url(r'content-entry', views.ContentEntryCreate.as_view()),
url(r'content-entry/(?P<id>\d+)$', views.ContentEntryUpdate.as_view()),
]
Everything is working fine except the ContentEntryUpdate
which always returns an error:
HTTP/1.1 405 Method Not Allowed
Allow: POST, OPTIONS
Content-Type: application/json
Date: Wed, 03 May 2017 14:40:03 GMT
Server: WSGIServer/0.2 CPython/3.6.1
Vary: Accept, Cookie
X-Frame-Options: SAMEORIGIN
{"detail":"Method \"PATCH\" not allowed."}
As you can see in the Allow
attribute, it seems that only the POST
and OPTIONS
methods are allowed by the server.
It's very strange since generics.UpdateAPIView
defines the put
and patch
methods.
I don't think it's a permission problem since I allow everything:
# settings.py
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.AllowAny'
]
}
What should I do to allow the HTTP PATCH
and PUT
methods?
Please make sure to mark the URLs with a start and end (^ and $ symbols).
What happens here is without the end mark, r'content-entry'
matches "/content-entry/4/" and therefore calls the creation view.
Use: r'^content-entry$'
and r'^content-entry/(?P<id>\d+)$'
instead.
