django - class based view store post data
Hello,
I am trying to use class based view to post data.
I have come across a weird issue. It is not saving data in the backend. I
get an error:
Expected view AddToUserProfile to be called with a URL keyword argument named
"pk". Fix your URL conf, or set the `.lookup_field` attribute on the view
correctly.
I have searched on google to see explanation on this error but could not
understand the explanation. Appreciate if someone can shed some light on this.
Here is my model:
class UserPrefs(models.Model):
Preferences = (
(1,'Likes'),
(1,'Dislikes'),
(1,'Shared'),
(1,'Rejected')
)
user = models.ForeignKey('auth.User', related_name='Hello')
name = models.ForeignKey(Stock)
value = models.CharField(max_length=20,choices=Preferences)
class Meta:
#managed = False
db_table = 'user_pref'
def save(self, *args, **kwargs):
super(Hello, self).save(*args, **kwargs)
class AddToUserProfile(generics.GenericAPIView):
permission_classes =
(permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly)
queryset = UserPrefs.objects.all()
serializer_class = UserPrefSerializer
lookup_fields = ('id')
def get(self, request, *args, **kwargs):
return HttpResponse('Hello there!')
def post(self, request, *args, **kwargs):
self.object = self.get_object()
context = self.get_context_data(object=self.object)
#eturn self.render_to_response(context)
def create(self, serializer):
serializer.save(owner=self.request.user)
Serializer code:
class UserPrefSerializer(serializers.ModelSerializer):
owner = serializers.ReadOnlyField(source='owner.username')
class Meta:
model = UserPrefs
fields = ( 'owner', 'name', 'value')
depth = 1
Url.py entry:
url(r'^Hello/setPrefs', views.AddToUserProfile.as_view()),

Re: CSRF verification failed when I use smart phone
We have started seeing this behavior occasionally. No code change in this
area, but sometimes (esp on phones) the CSRF cookie is wrong.
Our guess is too many cookies on the domain, but it is difficult to prove
this. Indeed, opening a new browser session resolves it... temporarily.

Migrate command does not respect options for db connections?
Context:
Django 1.7.1
PostgreSQL 9.4
I have the following database entry in settings:
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'xpto',
'USER': 'postgres',
'PASSWORD': 'postgres',
'HOST': 'localhost',
'PORT': '5432',
'OPTIONS': {
'options': '-c search_path=xpto,public'
}
}
}
And the following model:
class ModelA(models.Model):
att_a = models.CharField(max_length=10)
I' just created a migration with makemigrations for this app. It does not
have any indication of schema, whatsoever.
When I ran the migration, with migrate, the table ended up on the public
schema.
Bug?

Hi,
So I updated my django project from django 1.6 to 1.7.7 and when I run
"python manage.py migrate" I get this error stating that I have a
duplicate
label.
Here's the traceback

Installing custom SQL...

Not sure what to do here. I remove tastypie from the list of
INSTALLED_APPS in my settings and everything works fine. but I do need it.
Any suggestions ?
