DRF reverse cannot find view name - python

I am working of django rest framework api_root. It cannot find view even though I name it.
# board/urls.py
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns
from .views import BoardList, BoardDetail, api_root
app_name = 'board'
urlpatterns = [
path('boards/', BoardList.as_view(), name='board-list'), # board-list
path('boards/<int:pk>', BoardDetail.as_view(), name='board-detail'),
path('', api_root),
]
urlpatterns = format_suffix_patterns(urlpatterns)
# board/views.py
from django.contrib.auth.models import User
from django.shortcuts import render
from rest_framework import generics, permissions, serializers
from rest_framework.decorators import api_view
from rest_framework.response import Response
from rest_framework.reverse import reverse
from .models import Board
from .serializers import BoardSerializer
from .permissions import IsAuthorOrReadOnly
#api_view(['GET'])
def api_root(request, format=None):
return Response({
'boards': reverse('board-list', request=request, format=format) # board-list
})
class BoardList(generics.ListCreateAPIView):
queryset = Board.objects.all()
serializer_class = BoardSerializer
permission_classes = [permissions.IsAuthenticatedOrReadOnly]
def perform_create(self, serializer):
serializer.save(author=self.request.user)
It throws error,
Reverse for 'board-list' not found. 'board-list' is not a valid view function or pattern name.
Why it cannot find view name?

Since you included an app_name in your urls.py, you need to specify the view name with the app name, so:
#api_view(['GET'])
def api_root(request, format=None):
return Response({
'boards': reverse('board:board-list', request=request, format=format) # board-list
})

How do i rewrite my code with Routers? Django rest framework

I have this REST API:
urlpatterns = [
path('admin/', admin.site.urls),
path('users/', UserViewSet.as_view({'get': 'list',
'post': 'create',
'delete': 'delete'})),
path('users/<uuid:pk>/video/', UserViewSet.as_view({'post': 'video'}))
]
How can i rewrite this with routers?
Default router with register method creates API -> GET users/ and POST users/ and also DELETE /users/{id} but it's different from current, because i need DELETE /users/ endpoint.
Or, maybe, in this situation it would be more correct to use my code with dictionaries?
assuming that UserViewSet is indeed a viewset, you can use the restframework's default router to register the router for /users/, and then add an action to handle you /video/ route from that viewset.
urls.py
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register(r'users/', UserViewSet, basename='users')
urlpatterns = [
path('admin/', admin.site.urls),
]
urlpatterns += router.urls
viewsets.py
from rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import (
CreateModelMixin, RetrieveModelMixin,
DestroyModelMixin, ListModelMixin
)
from rest_framework.decorators import action
from rest_framework.parsers import MultiPartParser
class UserViewSet(CreateModelMixin, RetrieveModelMixin,
DestroyModelMixin, ListModelMixin, GenericViewSet):
# serializer class
# queryset
# permissions
#action(methods=['post'], parser_classes=(MultiPartParser,), detail=True)
def video(self, request, pk=None, *args, **kwargs):
# Implementation to upload a video
Edit
To create a bulk DELETE of users endpoint, I would create a Mixin class, as there is no django mixin for Deleting on the index of a router..
class BulkDeleteModelMixin:
def destroy(self, request, *args, **kwargs):
queryset = self.filter_queryset(self.get_queryset())
self.perform_destroy(queryset)
headers = self.get_success_headers(serializer.data)
return Response(serializer.data,
status=status.HTTP_201_CREATED, headers=headers)
def perform_destroy(self, queryset):
queryset.delete()
And inherit from this class in your viewset
viewsets.py
from rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import (CreateModelMixin, RetrieveModelMixin, ListModelMixin)
from some_app.mixins import BulkDeleteModelMixin
class UserViewSet(CreateModelMixin, RetrieveModelMixin,
BulkDeleteModelMixin, ListModelMixin, GenericViewSet):

How to add React JS's Link paths to DJango URLs backend

I have a model created for user, with fields- email_id and password
CRUD operations are implemented automatically, so how do I validate data passed from the login form in frontend
Please tell me what's wrong in the code. I am not able to do the login part.

404 Page Not Found "GET /accounts/login/?next=/profile/ HTTP/1.1" 404

I am getting some issues with my urls. I don't have any 'account/' route but i when I want to visit 'login/' and after logging in it should redirect me to my profile... but it is taking me to this route: "http://127.0.0.1:8000/accounts/login/?next=/profile/"
I am sorry if I've posted any unnecessary kinds of stuff:

except:
pass
if is_safe_url(redirect_path, request.get_host()):
return redirect(redirect_path)
else:
return redirect("login")
return super(LoginView, self).form_invalid(form)
set a variable in your urls.py of you mainapp as following
appname='mainapp'
now in your login view add following
def get_success_url(self):
return reverse('mainapp:profile')
Currently, in Django 3.2, the reverse method is written this way:
def get_success_url(self):
return reverse('profile')
No need to add appname var in your urls.py
