Django Adding Item Mismatching
I'm currently working on To-Do App using Django. I have two models Todo and Task. I want to create a Todo and under the todo items I want to create a task items. As I was able to add todo items and task items. But the problem is If I want to add task item for Maths by default all the task Items are getting added to the first todo items. I think It's becaude In Task modal(pop up) form I have linked function url to retrieve the todo objects id when the add button clicked and also added bootstrap modal(pop up) form to the a-tag in html. It's not retrieving the corresponding todo item id instead It takes the 1st todo item id.(refer below images) models.py class Todo(models.Model): date_created = models.DateTimeField(auto_now_add=True) completed = models.BooleanField(default=False) title = models.CharField(max_length=200) user_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def __str__(self): return self.title class Task(models.Model): heading = models.CharField(max_length=100) todo = models.ForeignKey(Todo, on_delete=models.CASCADE, related_name='tasks') date_created = models.DateTimeField(auto_now_add=True) completed = models.BooleanField(default=False) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def __str__(self): return self.heading views.py from django.shortcuts import render, redirect, get_object_or_404 from django.http import HttpResponse, Http404, HttpResponseNotFound, JsonResponse, HttpResponseRedirect from .models import Todo, Task from .forms import * from django.utils import timezone from django.contrib.auth.forms … -

Django Rest Framework + Swagger : error { "detail": "CSRF Failed: CSRF token missing or incorrect." }
Hello I am using Django Rest Framework along with Swagger. I am getting this error upon POST request. { "detail": "CSRF Failed: CSRF token missing or incorrect." } This is quite strange considering the POST request contains "X-CSRFToken: 01658Gyfzlhz2v6zgoZjtbHSrWzrVTBrlseyp2JMfVHvh6PzfamHpgxuh4eaVXad" This is the complete request curl -X POST "http://127.0.0.1:8000/api/order-post/" -H "accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -H "X-CSRFToken: 01658Gyfzlhz2v6zgoZjtbHSrWzrVTBrlseyp2JMfVHvh6PzfamHpgxuh4eaVXad" -d "customer_name=Muhammad%20Ahsan%20Mukhtar&country=Pakistan&address=Cb%20679%20Kashmir%20Colony%20Gujranwala%20Cantt&email=ahsan44411%40gamil.com&postal_code=52250&country_code=4343&phone_number=243434&tracking_number=4343" I have even tried using csrf_exempt but that does not help either, I get the same error. @method_decorator(csrf_exempt, name="dispatch") class OrderPost(generics.ListCreateAPIView): queryset = Order.objects.all() serializer_class = OrderSerializer I am using the default settings for Django Rest Framework which is SessionAuthentication I believe.

How to force autocomplete to work on https site
To autocomplete the phone field in my app I use django-ajax-selects app (DAS): when an user types the numbers in the field, DAS displays the matching phone numbers. On localhost and on the site with http it works fine, but on the https site it doesn't work. The root of the problem is that the request from DAS to channel with phone numbers query via https is blocked giving the error 403 (Forbidden). An example from browser console by typing '911' in the phone field: jquery-2.2.4.min.js:4 GET https://mysite/ajax_select/ajax_lookup/clients?term=911 403 'clients' is the channel defined as: @register('clients') class ClientsLookup(LookupChannel): model = Client min_length = 4 # Minimum number of characters user types before a search is initiated. # Queryset matching the characters typed by the user def get_query(self, q, request): qs = self.model.objects.filter(phone__icontains=q)[:10] return qs Definitely, I need to tell the https server that the request from one part of my app to another part of my app is ok, but how? -

How to access path url parameter in DRF serializer?
Short question: What's the appropriate way to access a url path parameter (not a url query parameter) in a Django DRF serializer? Context: A have a Django DRF api, where I have a url similar to : /api/blogposts/:blogid/comments that is handled by a generic view: class MyCommentsView(generics.ListCreateAPIView): queryset = Comment.objects.all() serializer_class = CommentSerializer (blog and comment are just example resources; i am working with different ones) This view allows via a POST call to create new comments. For legacy reasons, the request will contain the blog_id also as a request body parameter. In my Serializer I want to check if the :blogid in the url is identical to the blog_id in the body. Currently I do the following, but the path splitting and element selecting feels very fragile. So, is there a better way? class CommentSerializer(serializers.ModelSerializer): class Meta: model = Comment fields = [..., 'blog_id', ... ] ... def validate_blog_id(self, value): blogid_in_url = int(self.context['request'].path.split('/')[-2]) # <- better way? if blogid_in_url != value: ... Note: my question is about a url path parameter, not a url query parameter. I know a url query parameter can be accessed via self.context['request'].query_params. -
