How to send the value of XMLHttpRequest.save() to django view?
I have an AJAX/XMLHttpRequest and I want to send the result of window.confirm to view and use it. Currently this is my js: $(".release_hold").click(function () { var id = $(this).val(); $.ajax({ url: "/account/release_hold/" + id + "/", dataType: "json", success: function (data) { if (data.message != null) { // alert(data.message); result = window.confirm(data.message) == true; alert(result); if (result) { var xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", "../release_hold/" + id + "/", true); # I think this should be POST. xmlhttp.send(result); } } }, }); }); Now on my views.py, I dont know if I need/how to add the result in my parameter. Once the result of windows.confirm is inserted, I can proceed. def release_hold(request, id, *args, **kwargs): ... if request.is_ajax() and request.POST : # Add result here. .... data = { 'message': "RELEASE DONE" } else: .... data = { 'message': "Are you sure you want to release record?" } return JsonResponse(data) -
DRF - How to queryset to only objects that the user is the owner of within an intermediate model?
I'm my DRF API, I have an intermediate model Ingredient that links two models, Product and Recipe. class Product(models.Model): name = models.CharField() class Recipe(models.Model): name = models.CharField() user = models.ForeignKey(User, on_delete=models.CASCADE) ingredients = models.ManyToManyField(Product, through='ingredient') class Ingredient(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE) quantity = models.FloatField(default=0) In my current DRF generics.CreateAPIView for Ingredient, I want it to only display and allow a user to see and send a post request to create a new Ingredient entry for a Recipe that they own. But right now it keeps displaying Recipes for all users. I tried filtering the Recipe for the Ingredient model in my serializers.py with: serializers.py: class IngredientPostSerializer(serializers.ModelSerializer): recipes = serializers.SerializerMethodField() def get_recipes(self, obj): recipes = Recipe.objects.filter(user_id=self.request.user.id) return recipes class Meta: model = Ingredient fields = '__all__' -

Unit/Functional Tests Vs Validators
I have recently started web development using Django. What confuses me the most that, why do we create tests for scenarios like "Check if password is provided", "Check if password is correct", "Check if a password is at least 8 characters long" etc. when we can do the same thing using validators in Django. Is there a specific advantage of using tests over validators? Thanks. -

Pagination links appearing null after applying Custom Pagination in django rest framework
I used custom pagination as mentioned in Django rest framework. In that, I had to use my project name to give the path to CustomPagination, but every time it says module not found. Then I manually import the pagination file in my views. It did work but my pagination links are appearing null. I have posted the picture here below. My views: from .pagination import CustomPagination class ProductAPIView(ListAPIView): permission_classes = [AllowAny] queryset = Product.objects.all() serializer_class = ProductSerializer filterset_class = ProductFilter pagination_class = CustomPagination My pagination.py file class CustomPagination(PageNumberPagination): def get_paginated_response(self, data): return Response({ 'links': { 'next': self.get_next_link(), 'previous': self.get_previous_link() }, 'count': self.page.paginator.count, 'results': data }) My settings file: # 'DEFAULT_PAGINATION_CLASS': 'RupseOnline.core.pagination.CustomPagination', 'PAGE_SIZE': 100, I have commented out the pagination class and imported it manually in views because it says module not found. -
Inherit Django application (a set of apps)
I have an architectural problem. My team have large Django DRF application (lets name it "portal-backend") combined of set of apps, not installed as a modules but created manually. The apps are: blogs, news, entries, adminapi, gallery, comments, events, ideas, microposts, reactions, moderation, profile, and so on (about 50 apps). Now I need to make some kind of "inheritance", use this product as a "base" in other team, and allow them to make changes in their nested classes. For example if they need to change class blogs.views.BlogViewSet, they can just inherit it by they own class. The "base" application must be installed with pip (if possible) or pulled from git (it's a single repo) So, the main portal-backend shouldnt be changed in other team, just used as a base and extended by inheritance Ideally my existing application should became some kind of high-level framework to create other portal-backends on the base of it with required modifications and additions on top of it. What variants I thought about: Split whole application into app-modules, put it into separate git repos, and install each app as a pip module. This method requires lots of work and has a problem that all apps are … -

Get Dynamic Select option in Clone Node using Javscript
I'm trying to create a form where I'm giving dynamic select option i.e one select option will depend on another select option, as you can see in the Image below, if Gender is male and Child the age group is between 1-18 similarly for Adult its greater than 18.

I have two websocket servers, call them Main and Worker, and this is the desired workflow: Client sends message to Main Main sends message to Worker Worker responds to Main Main responds to Client Is this doable? I couldn't find any WS client functionality in Channels. I tried naively to do this (in consumers.py): import websockets class SampleConsumer(AsyncWebsocketConsumer): async def receive(self, text_data): async with websockets.connect(url) as worker_ws: await worker_ws.send(json.dumps({ 'to': 'Worker' })) result = json.loads(await worker_ws.recv()) await self.send(text_data=json.dumps({ 'to': 'Client' }) However, it seems that the with section blocks (Main doesn't seem to accept any further messages until the response is received from Worker). I suspect it is because websockets runs its own loop, but I don't know for sure. The response { "to": "Client" } does not need to be here, I would be okay even if it is in a different method, as long as it triggers when the response from Worker is received. Is there a way to do this, or am I barking up the wrong tree? If there is no way to do this, I was thinking of having a thread (or process? or a separate application?) that communicates with Worker, and uses channel_layer to …
