API Django

[Phako Perez]

Hi all,

i'm really new on Django, trying to create an RESTful API, and getting this
error:

curl -i -U Elly:Elly -H "Content-Type: application/json" -X GET
http://192.168.100.22:8000/schedule/3/


HTTP/1.1 403 Forbidden

{"detail":"Authentication credentials were not provided."}

on my settings.py added below

REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.BasicAuthentication',
'rest_framework.authentication.SessionAuthentication',
'rest_framework.permissions.IsAuthenticated'
),
}


views.py

from schedule.models import Schedule
from users.models import User
from rest_framework import exceptions
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.authentication import SessionAuthentication,
BasicAuthentication
from rest_framework.permissions import IsAuthenticated

from schedule.serializers import ScheduleSerializer


class ScheduleList(APIView):

permission_classes = (IsAuthenticated,)

def authenticate(self, request):

if not username:
return None
try:
user = User.objects.get(username=username)
except:
raise exceptions.AuthenticationFailed('No such user')
return Response(user, None)

queryset = 
Schedule.objects.all().filter(user=User.objects.all().filter(id=5)[0])
serializer_class = ScheduleSerializer

def perform_create(self, serializer):

Do you mean bootstrap? STL doesn't care about that and it's not clear what
you mean. Can you share the code so that we can help you.

How can I implement built in signals, for my app?

[Joel Mathew]

How to implement built in signals, for my app?

I have a project myappointments, with two apps appointments and clinic in it.

Objective:
When a user logins, details should be entered in the database.

appointments/models.py:

class Event(models.Model):
id=models.AutoField(primary_key=True, unique=True)
type=models.CharField(max_length=60)
description = models.CharField(max_length=150)
time = models.DateTimeField(default=timezone.now)

appointments/__init__.py:

default_app_config = 'appointments.apps.AppointmentsConfig'

appointments/apps.py:

from django.apps import AppConfig
class AppointmentsConfig(AppConfig):
name = 'appointments'
def ready(self):
import appointments.signals  # noqa

appointments/signals.py:

from django.contrib.auth.signals import user_logged_in
from django.dispatch import receiver
def record_loggedin(sender, user, request, **kwargs):
  ev = Event(type="Login", description = 'User logged in:
{}'.format(request.user.id))
  ev.save()
  print("User has logged in. Saved event to DB.")
  user_logged_in.connect(record_loggedin)

What other modifications do I need to do this?

That's about right - you should ship and maintain the file yourself now.

Re: Using the URLconf defined in polls.urls, Django tried these URL patterns, in this order

[Motaz Hejaze]

first , no spaces are allowed in URLS
as  Manjunath said
replace path(' ', views.index, name='index') with path('', views.index,
name='index') in your polls/urls.py and check the result.

second , run the server
python manage.py runserver

third check the url
go to http://127.0.0.1:8000/polls

Re: Using the URLconf defined in polls.urls, Django tried these URL patterns, in this order

I think you have a space in your url path.

replace path(' ', views.index, name='index') with path('', views.index, 
name='index') in your polls/urls.py and check the result.
