How can I get django to work on https using elastic beanstalk and apache?
I have my .config files set up using the information available on aws and I have my load balancer listening on 443. My website is being served correctly via https when I connect using my elastic beanstalk url. Of course that url is not what my ssl certificate lists so there's an error but none the less, it is displaying all the html and static files. Https seems to be working there. When I attempt to visit my custom domain using http everything also displays correctly so my application seems fine, but when I attempt https using my custom domain nothing is loaded from my server. I just get the "Index of /" page. This is what I receive when my ALLOWED_HOSTS is incorrect so I assume it's something super simple in my settings file that is blocking django from allowing apache to serve the content over https to my custom domain. Or else theres one other place I'm missing that needs me to register my domain with my load balancer? Is that a thing? I feel like I've been scouring the internet for help here so any suggestions are very much appreciated. One other note is that I have … -

Does queryset.values_list makes another call to db?
Let's say I have an already evaluated queryset. # queryset is evaluated here queryset = MyModel.objects.filter(name="blabla") for obj in queryset: # do some stuff if I call .values_list on this queryset later on, does it make an extra call to the database or fetch the response from the queryset object cache? obj_map = {k: v in queryset.values_list("id", "name")} # <- does it make a call? -
Django: Ajax Call Returning Expected Values, Not Entering Success
I have three ajax calls in an input form. All three operate in the same way. User clicks submit button, and URL params are passed to a function in views.py. The function is executing as expected and returning the values to the route in the Ajax call. When I visit the specific route with params route/cust-search?name=example&filter_by=example, I can see my data. The last stage uses the success function to grab the data from the route and load it into the pages' layout. My other two calls work and are set up in the exact same way. Why is this call not entering success? <script> $(document).on('submit','#cust_search',function(e){ e.preventDefault(); e.stopPropagation(); $.ajax({ type:'GET', url:'cust-search/', data:{name:$('#gc-input_name_search').val(), filter_by:$('#gc-input_filter_by').val(),}, success:function update_items(){ $('.search-results_table_body').html('').load( "{% url 'CustSearch' %}?name=" + $('#gc-input_name_search').val() + "&filter_by=" + $('#gc-input_filter_by').val()); }, error: function(){} }); e.stopImmediatePropagation(); return false; }) </script> -

(Django) Making Custom on_delete & CASCADE functions
There is a legacy codebase and its deletion system has to be changed to soft-deletion. I made an additional field in each model like so: is_deleted = models.BooleanField(default=False) and in the utils.py file, I have defined some functions to utilize the is_deleted field . . . def card_related_objs_soft_cascade(instance): print("initiating 'card_related_objs_soft_cascade'...") with transaction.atomic(): with suppress(ObjectDoesNotExist): instance.order.soft_delete() instance.invoices.all().qs_soft_delete() instance.payments.all().qs_soft_delete() def account_related_objs_soft_cascade(instance): print("initiating 'account_related_objs_soft_cascade'...") with transaction.atomic(): instance.contacts.all().qs_soft_delete() instance.meeting_notes.all().qs_soft_delete() instance.attachment.all().qs_soft_delete() class ReusableModelMethods: def soft_delete(self): with transaction.atomic(): print(f"initiating 'soft_delete' on {self.__class__.__name__} instance") ops = { "Board": board_related_objs_soft_cascade, "CardList": cardlist_related_objs_soft_cascade, "Card": card_related_objs_soft_cascade, "Customer": account_related_objs_soft_cascade, "Supplier": account_related_objs_soft_cascade, } self.is_deleted = True self.save() ops.get(self.__class__.__name__, lambda *args: None)(self) class ReusableQuerySetMethods(models.query.QuerySet): @classmethod def as_manager(cls): manager = SoftDeleteManager.from_queryset(cls)() manager._built_with_as_manager = True return manager def qs_soft_delete(self, *args, **kwargs): print("initiating 'qs_soft_delete'...") for instance in self: instance.soft_delete() self._result_cache = None qs_soft_delete.alters_data = True However, when you look at this, there is a lot to maintain as the codebase expands. For instance, in def account_related_objs_soft_cascade(instance), there are three models (contacts, meeting_notes, attachment) related to this account model. As we add more models, I must add more of instance.some_model_set.all().qs_soft_delete() and the chance is, I would forget to do this... And thus, I would like to implement something that does this automatically, hence I looked at CASCADE … -

Django Channel stuck for a while
currently I am having some problems with the Django channel. I have been developed a web application to receive data from GNSS and display its position as a machine in the frontend. So I have used the Django channel to connect and received data from GNSS. After we connected to GNSS, around 15 to 17 seconds, we can process data inside the Django channel and return its position into the frontend but after the next 17 seconds, data are still receiving in the Django channel but it stops return data to the frontend to display and when I disconnected real GNSS from the system, those data after 17 seconds are starting processing again. Does anyone know how to solve this? Thank you -

LDAPInvalidServerError at /login/ No exception message supplied
I used Python3 in windows 10 to write a django2 web app. I tried to configure the LDAP login, but failed. When I test using postman to test, it could get the reply successfully. That is, I send a request to https://example.com/staff, with some authentication code and payload containing username and password, and it reply me with the LDAP reply. However, when I tried to using ldap3 in Django, seems like Django ldap3 requires a ldap server address and port, a web address containing LDAP API could not work. class LDAPBackend: def authenticate(self, request, username=None, password=None, **kwargs): now = datetime.datetime.now() text = str(now.day) + 'ls@bBk3y' def computeMD5hash(my_string): m = hashlib.md5() m.update(my_string.encode('utf-8')) return m.hexdigest() # set username to lowercase for consistency username = username.lower() # get the bind client to resolve DN logger.info('authenticating %s' % username) # set your server server = Server("https://example.com/staff") try: print("begin connect!") conn = Connection(server, user=username, password=password, auto_bind=True,) conn.open() conn.bind() print("connected") except LDAPBindError as e: logger.info('LDAP authentication failed') logger.info(e) return None user = UserModel.objects.update_or_create(username=username) return user def get_user(self, user_id): try: return UserModel._default_manager.get(pk=user_id) except UserModel.DoesNotExist: return None always show this: LDAPInvalidServerError at /login/ No exception message supplied -
Django Rest Framework custom permission not working
I want users to have access only to the records that belong to them, not to any other users' records so I've created the following view: class AddressViewSet(viewsets.ModelViewSet): authentication_classes = (TokenAuthentication,) permission_classes = [IsAuthenticated, IsOwner] queryset = Address.objects.all() def retrieve(self, request, pk): address = self.address_service.get_by_id(pk) serializer = AddressSerializer(address) return Response(serializer.data, status=status.HTTP_200_OK) I want only the owner of the records to have access to all the methods in this view ie retrieve, list, etc (I'll implement the remaining methods later) so I created the following permissions.py file in my core app: class IsOwner(permissions.BasePermission): def has_object_permission(self, request, view, obj): print('here in has_object_permission...') return obj.user == request.user this wasn't working, so after going through stackoverflow answers I found this one Django Rest Framework owner permissions where it indicates that has_permission method must be implemented. But as you can see in that answer, it's trying to get the id from the view.kwargs but my view.kwargs contains only the pk and not the user. How can I fix this? Do I need to implicitly pass the user id in the request url? that doesn't sound right. Here's the test I'm using to verify a user cannot access other user's records: def test_when_a_user_tries_to_access_another_users_address_then_an_error_is_returned(self): user2 = UserFactory.create() … -
How to set up different weekday/weekend schedules for celery beat in Django?
How do I go about scheduling my tasks differently for weekdays and weekends in celery beat?

I have to loop over all the listings first and match with the product id in my wish list so i can access the fields such as title and image.. is there any easier way to do this than looping over all the listings until finding the matched ones ? views.py def add_to_wishlist(request, product_id): product = WishList.objects.filter(listing_id=product_id, user=request.user.username) if product: product.delete() else: product = WishList() product.listing_id = product_id product.user = request.user.username product.save() return HttpResponseRedirect(request.META['HTTP_REFERER']) def wishlist(request): product = WishList.objects.filter(user=request.user) all_listings = AuctionListing.objects.all() return render(request, "auctions/wishlist.html", { 'wishlist': product, 'all_listings': all_listings }) models.py class AuctionListing(models.Model): title = models.CharField(max_length=100) description = models.TextField() start_bid = models.IntegerField(null=True) image = models.CharField(max_length=1000, blank=True) category = models.CharField(max_length=100) seller = models.CharField(max_length=100, default="Default_Value") class WishList(models.Model): user = models.CharField(max_length=64) listing_id = models.IntegerField() wishlist.html {% extends "auctions/layout.html" %} {% block title %}Users Wishlist {% endblock %} {% block body %} <div class="col-12 mx-auto"> <h1 class="h3">My Wishlist</h1> <div>Manage your wishlist</div> {% if wishlist %} {% for listing in all_listings %} {% for product in wishlist %} {% if listing.id == product.listing_id%} <div class="card-mb-3"> … -
How to solve Method "POST" not allowed 405
I'm using Django Rest Framework for API and I faced this problem. In views.py my class inherits from ModelViewSet, but for some reason it doesn't allow making a POST request. For frontend I'm using React JS and I make a POST request from there. And in the end I'm getting an error like this: POST http://127.0.0.1:8000/api/software/3/ 405 (Method Not Allowed). Here's views.py: from rest_framework.viewsets import ModelViewSet from .serializers import ( CategorySerializer, SoftwareSerializer, SoftwareListRetrieveSerializer, CategoryDetailSerializer, CustomPaginatorSerializer ) from ..models import Category, Software class CategoryViewSet(ModelViewSet): queryset = Category.objects.all() serializer_class = CategorySerializer pagination_class = None action_to_serializer = { "retrieve": CategoryDetailSerializer, } def get_serializer_class(self): return self.action_to_serializer.get( self.action, self.serializer_class ) class SoftwareViewSet(ModelViewSet): queryset = Software.objects.all() serializer_class = SoftwareSerializer pagination_class = CustomPaginatorSerializer action_to_serializer = { "list": SoftwareListRetrieveSerializer, "retrieve": SoftwareListRetrieveSerializer } def get_serializer_class(self): return self.action_to_serializer.get( self.action, self.serializer_class ) Here's urls.py: from rest_framework import routers from .views import CategoryViewSet, SoftwareViewSet router = routers.SimpleRouter() router.register('category', CategoryViewSet, basename='category') router.register('software', SoftwareViewSet, basename='software') urlpatterns = [] urlpatterns += router.urls
