How to loop to add event handler to buttons?

Django AJAX can't find url
I'm using AJAX request to delete comment from product page, but django can't find url (I'm getting this log ). Box url: path('box/<int:id>', views.box, name='box') , delete url: path('delete-comment/<int:id>', views.delete_comment, name='delete_comment'),. My AJAX call: comment.addEventListener("click", () => { fetch(`delete-comment/${comment.dataset.comment_id}`, { method: "DELETE", headers: { "X-Requested-With": "XMLHttpRequest", } }) }); And view: def delete_comment(request, id): if request.headers.get("X-Requested-With") == "XMLHttpRequest": if request.method == 'DELETE': comment = Comment.objects.get(id=id) if comment.user == request.user: comment.delete() return HttpResponseBadRequest('ok') else: return HttpResponseBadRequest('Invalid request') I think there is something wrong with url. Why is django looking for /box/delete-comment/id, shouldn't it look for /delete-comment/id or /box/box-id/comment/id? I tried some options but none of them worked. I also couldn't find any similar problem. I even can't identify problem properly. Can you help me? -

Pytest-django won't post json data leading to assertion error. Not permission/method related
I'm writing a test for my django online project and I'm stuck in a function that returns 201 if data is valid (it's testing if data is valid when creating a new product for the store.). Django version 4.1.7 Django Rest Framework 3.14.0 pytest 7.2.2 pytest-django 4.5.2 The issue is that no matter what data I input in the function it always returns a 400 error. I'm sure it's not a permission issue because I've got authenticate(is_staff=True), which works in the previous functions. Also, I'm able to post a "Product" both in the Admin panel and in the products url if i'm logged with an account with Staff privileges. Here's the test_products.py code: from store.models import Collection, Product from rest_framework import status import pytest from model_bakery import baker @pytest.fixture def create_product(api_client): def do_create_product(product): return api_client.post('/store/products/', product) return do_create_product @pytest.mark.django_db class TestCreateProduct: def test_if_user_is_anonymous_returns_401(self, create_product): response = create_product({'title': 'a'}) assert response.status_code == status.HTTP_401_UNAUTHORIZED def test_if_user_is_not_admin_returns_403(self, authenticate, create_product): authenticate() response = create_product({'title': 'a'}) assert response.status_code == status.HTTP_403_FORBIDDEN def test_if_data_is_invalid_returns_400(self, authenticate, create_product): authenticate(is_staff=True) response = create_product({'title': ''}) assert response.status_code == status.HTTP_400_BAD_REQUEST assert response.data['title'] is not None def test_if_data_is_valid_returns_201(self, authenticate, create_product): authenticate(is_staff=True) response = create_product({ "title": "abc", "slug": "abc", "inventory": 1, "unit_price": 2, "collection": … -

Django - How do I update one field after my ModelForm has changed another?
I have a ModelForm that currently is used to update 2 fields in a Model. Users don't have to update both fields, however, when they do update the "study" field I need to trigger an update to the "user_study_tag" field to 'True' in the model instance. If they simply update the "notes" field (and not the "study" field), I don't want that update happening. forms.py class Run_UpdateForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop("request") site_study_list = kwargs.pop("site_study_list") super(Run_UpdateForm, self).__init__(*args, **kwargs) self.fields["study"].queryset = Study.objects.filter(name__in=site_study_list) class Meta: model = Runs fields = ( "study", "notes", ) models.py class Runs(models.Model): name = models.CharField(max_length=200) guid = models.CharField(max_length=100) site = models.CharField(max_length=30, choices=site_choices, default="-") instrument = models.CharField(max_length=30, default="-") study = models.ForeignKey(Study, on_delete=models.CASCADE, null=True, blank=True) user_study_tag = models.BooleanField(default=False) project = models.CharField(max_length=30, default="-") inventory = models.BooleanField(default=False) inventory_missing = models.BooleanField(default=False) inventory_dismissed = models.BooleanField(default=False) qc_run = models.BooleanField(default=False) analysis_end_date = models.DateTimeField(default=datetime.now, blank=True) archive = models.BooleanField(default=False) notes = models.CharField(max_length=200, default="-", null=True, blank=True) def __str__(self): return f"{self.name}" I thought I could use the clean(self) method in the model, but I don't think that is the right way to handle this issue since I don't know how to compare the form self.study to the model study that is potentially being changed. -
List comprehension vs. for loop
In an effort to avoid Django ModelSerialization performance hits, I am looking at "serializing" a result set on my own. Research says that list comprehension should be the fastest, but my own tests are showing nested for loops being consistently faster. I have raw DB results (100) that need to be converted into a list of OrderedDict based on an ordered list of fields (14). Is my use case too complex for the list comprehension performance advantage, or my sample size too small? Maybe the performance is negligible? Nested for-loop (0.000919342041015625) serialized = [] start = time.time() for raw in results: result = OrderedDict() for index, field in enumerate(fields): result[field] = raw[index] serialized.append(result) end = time.time() print("For loop + for loop " + str(end - start)) Nested list comprehension (0.011911153793334961) serialized = [] start = time.time() serialized = [OrderedDict((field, raw[index]) for index, field in enumerate(fields)) for raw in results] end = time.time() print("List comprehensions + list comprehensions " + str(end - start)) For-loop + list comprehension (0.020151615142822266) serialized = [] start = time.time() for raw in results: result = OrderedDict((field, raw[index]) for index, field in enumerate(fields)) serialized.append(result) end = time.time() print("For loop + list comprehensions " + str(end - start)) -

I have a model like this Class ExchangeMarket(models.Model): base_currency = models.ForeignKey(Currency) quote_currency = models.ForeignKey(Currency) ... various other fields And some entries like base: EUR, quote: USD ... base: EUR, quote: USD ... base: USD, quote: EUR ... base: BTC, quote: USD ... ... I need to find entries sharing the base/quote combination, i.e. in my example that's the first three How to create such a queryset? If I do something like ExchangeMarket.objects.all().values('base_currency', 'quote_currency').annotate(pks=ArrayAgg('pk')) I will only find exact matches with same bases and quotes (like EUR/USD, first two of my entries) while I need to find both EUR/USD and USD/EUR. Thanks! -
Django: color test result in console
I have a Django project for which I have tests (nothing special). The thing is I'd like to have colored results when running tests and I don't know how to do that. On a daily basis, I run tests from my Ubuntu terminal with the command python3 ./backend/manage.py test --settings="backend.settings.testing" backend/ --no-input --verbosity=2 and applying the migrations looks like this at the beginning of the tests : whereas the tests themselves have uncolored results like so : My question is : Is there a simple way to get those ok colored in green and if applicable 'ko' in red ? Thank you in advance.
