How can I show in cart items in my index view?
I'm working on an ecommerce app, and I have a template that displays all my products. I want to show how many of the item are in the cart. But I can't seem to figure out how to get that information from my for loop. Code: template {% for product in products %} {{product.title}} - {{product.quantity_in_cart}} {% endfor %} (As of right now, product.quantity_in_cart does nothing. I would like it to show how many of this product are in the cart) view def product_index(request): title = "My Products" products = Product.objects.all() order = get_cart(request) cart = Order.objects.get(id=order.id, complete=False) items = cart.orderitem_set.all() context = { 'title' : title, 'products' : products, 'cart' : cart, 'items': items } return render(request, "store/product_index.html", context) models class Order(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True) complete = models.BooleanField(default=False, null=True, blank=False) class OrderItem(models.Model): product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True) order = models.ForeignKey(Order, on_delete=models.SET_NULL, null=True) quantity = models.IntegerField(default=0, null=True, blank=True) date_added = models.DateTimeField(auto_now_add=True) class Product(models.Model): name = models.CharField(max_length=64) slug = models.SlugField(unique=True, null=True) description = RichTextField(blank=True) price = models.DecimalField(max_digits=8, decimal_places=2) quantity = models.IntegerField() -

django form implement AJAX for show hidden fields
So I got a simple form of COUNTRY, AREA, DISTRICT, CITY. In this form there are 4 more fields: What I'm trying to do is to filter the data. So when the user select a Country, the area field(select) will show all the areas that belong to this Country. Also when the user select a area, the module field(select) will show all the districts that belong to this field. If you check the code, you will see it's kinda simple. I know how to filter the queryset but I don't know how to use AJAX to do that. Tried many tutorials but couldn't find something so I'm sorry for not posting code. If you can point me to the right tutorial, example or give me some code to start working on it... my views.py class OrderCreateView(OrderViewMixin, core.CreateView): form_class = OrderForm template_name = '.....' def form_valid(self, form): .... return super().form_valid(form) def get_ajax(request): if request.is_ajax: logs = Order.objects.filter(country_id=request.GET['country']) data = serializers.serialize("json", logs) return HttpResponse(data, content_type='application/json') urls.py path('get_ajax/',views.get_ajax,name='get_ajax'), forms.py class OrderForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(OrderForm, self).__init__(*args, **kwargs) self.fields['country'].queryset = Order.objects.all() self.fields['area'].queryset = Order.objects.none() class Meta: .....

How to send and receive dropdown selected option using AJAX
I have been working on a Django-based web application and I'm trying to send the selected option from a dropdown to services.py which handles models.py updating. I want the user to select one of the options in the dropdown and then send it to services.py to filter the payload coming from AWS. This is my dropdown: <div class="dropdown is-active" style="margin-bottom:10px"> <div class="select" id="dropdown-menu" role="menu"> <select class="dropdown-content" id="select"> <option class="dropdown-item" selected> AWS Accounts </option> <option value="558232680640" class="dropdown-item"> 558232680640 </option> <option value="903500686888" class="dropdown-item"> 903500686888 </option> <option value="183070076065" class="dropdown-item"> 183070076065 </option> <option value="885703380506" class="dropdown-item"> 885703380506 </option> <hr class="dropdown-divider"> <option value="*" class="dropdown-item"> All Accounts </option> </select> </div> </div> This is the javascript: $(document).ready(function() { var dropDown = $("#select"); dropDown.click(function() { $.ajax({ url: "{{ api_refresh_url }}", method: "POST", data: $("#select").val(), dataType: 'json', cache: false, }); }); }); and this is where I want to receive the data in services.py: class AWSEC2InstanceConnector: """ AWS Boto3 wrapper for connecting to the EC2 client and viewing EC2 instances """ last_update_time = datetime.min def update(self): self.last_update_time = datetime.now() instances = [] lambda_client = boto3.client('lambda') lambda_response = lambda_client.invoke(FunctionName='arn:aws:lambda:us-east-1:183070076065:function:cbi-instance-info') lambda_payload = json.loads(lambda_response['Payload'].read()) # HACK: using json.loads seems to avoid escaping the lambda response lambda_response = json.loads(lambda_payload['body']) for instance in lambda_response: instances.append(EC2Instance( … -
How to pass jquery variable into a custom django template tag?
I have a custom template tag that I got from this post. The tag is as follows: @register.filter def get_item(dictionary, key): return dictionary.get(key) In my Django template script: $(document).on('click', function() { var id = "'" + $(this).prop('id') + "'" $('img').prop('src', '{{dict|get_item:id}}'); }); Where dict is a dictionary that I pass to my Django template from my view. When I run the above code, django reads id as 'id' and not the value of the variable I set. How do I pass the jqeury variable into my custom template tag? -
Django prefetch query looping is quite slow
I have the following models. class ReportUserAnswers(models.Model): .... answers = models.ManyToManyField(ReportQuestionAnswerChoices, blank=True) ... class ReportQuestionAnswerChoices(models.Model): name = models.CharField(max_length=500) In my view i need to get all answers users have given. The choices they select are stored in 'answers' field. To get the answers i use the following query: answers = ReportUserAnswers.objects.filter( ... ).prefetch_related( "answers", ).distinct() I then need to loop over to find the answers chosen. for ans in answers: last = len(ans.answers.all()) - 1 for i, answer_given in enumerate(ans.answers.all()): answer_text += answer_given.name if not i == last: answer_text += "|" In a queryset I have 5000 answers, this loop takes around 20 seconds. Which seems very slow (crashes live server). I looked at the prefetch query directly in SQL, and that returns 2270 rows. So i guess the logic is looping 5000 times and looking in a table of 2270 for answers.all() The question is, is there a better approach or any thing i can do to cut the loop time? -

MongoDB doesn't work locally because of SRV error (no answer)
Situation We are working on the backend of our project consisting of two services written in Django and FastAPI. Both services use MongoDB as their database system. In Django we use djongo==1.3.0 for ORM compatibility. In FastAPI we use odmantic==0.3.4. Both of these libraries use pymongo==3.11.3 underneath. This MongoDB SRV error has been an issue for our Django service ever since we created it, but we managed to somehow work around it by not using the latest packages, such as: Django==2.2.20 djongo==1.3.0 pymongo==3.11.3 Recently due to security risks we had to upgrade: urllib3 from 1.25.8 to 1.26.5 pydantic from 1.8.1 to 1.8.2 Django from 2.2.20 to 2.2.22 Those were suggested by GitHub's dependabot.
