How should I serve my API? (authentication without password)
My question on itself isn't a problem in coding, instead I'm having doubts in the design of the user authentication of my API. Sorry if this isn't a question fit for stack overflow I'm developing an API in Django that serves HTML templates. It's going to be served to pages, each one has a set of users. I was planning in following the design described here: Why and when to use API keys So basically, each page will have its own API key, and in order for the users to use the API, the page will request a temporary token for the user. My question is, how could I generate the temporary tokens? Is there a library that deal with this? I had no luck searching. -
Django doesn't send email
I encountered an issue where Django is not sending emails to the specified email address. I would greatly appreciate your assistance. views.py def register(request): form = CreateUserForm() if request.method == 'POST': form = CreateUserForm(request.POST) if form.is_valid(): user = form.save() user.is_active = False user.save() current_site = get_current_site(request) subject = 'Account verification email' message = render_to_string('account/registration/email-verification.html', { 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': user_tokenizer_generate.make_token(user), }) print(message) user.email_user(subject=subject, message=message) return redirect('email-verification-sent') context = {'form':form} return render(request, 'account/registration/register.html', context=context) def email_verification(request, uidb64, token): unique_id = force_str(urlsafe_base64_decode(uidb64)) user = User.objects.get(pk=unique_id) if user and user_tokenizer_generate.check_token(user, token): user.is_active = True user.save() return redirect('email-verification-success') else: return redirect('email-verification-failed') token.py from django.contrib.auth.tokens import PasswordResetTokenGenerator class UserVerificationTokenGenerator(PasswordResetTokenGenerator): def _make_hash_value(self, user, timestamp): user_id = str(user.pk) ts = str(timestamp) is_active = str(user.is_active) return f"{user_id}{ts}{is_active}" user_tokenizer_generate = UserVerificationTokenGenerator() settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = '587' EMAIL_USE_TLS = 'True' EMAIL_HOST_USER = 'XXX@gmail.com' EMAIL_HOST_PASSWORD = 'XXX' EMAIL_HOST_USER and EMAIL_HOST_PASSWORD are correct I have already tried using SSL instead of TLS, disabling two-factor authentication, and removing the line 'EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' -

How to add global ranking annotation to subsequent Django queries?
I have a Django model that looks like this: class LeaderboardScore(models.Model): score = models.FloatField() player_account = models.ForeignKey(PlayerAccount, on_delete=models.CASCADE) timestamp = models.DateTimeField() This represents top scores in a game. The scores are ranked by score descending and timestamp ascending, so if two scores are the same, the earliest score is ranked higher. Every time I do a query on the leaderboards, I'd like to include the global ranking of each instance in the query result. I can do that successfully when I'm querying all the scores like so: lq = LeaderboardScore.objects.filter(leaderboard__id=1).annotate( rank=Window( expression=DenseRank(), order_by=[F('score').desc(), F('timestamp').asc()] ) ) This will correctly at a rank field with the ranking. But if I take the above query and filter it by player_account like so: # rank will be 1, but should be the global ranking lq.filter(player_account__id=123)[0].rank then the ranking resets so that the first item in the query has the rank of 1, even though its global rank should be different. How do I preserve the global ranking? -

How can I run a kafka consumer in a django project so that messages will passed to django project
I am running my kafka consumer (from the confluent_kafka library) in a separate django management command. (I did this because I couldn't find a way of running a kafka consumer within the runserver process in django without blocking up the runserver process. If there is a better way of doing this I would love to hear suggestions) My projects requirements are: djnago rest api project will receive kafka message for designated topic project will create an instance of model1. creation of model1 will propagate further actions/logic such as creating/updating other models + sending further kafka messages. My issue comes when designing logic to meet my requirements. Requirement 3 can be met using django signals and there is already code that implements these further actions/logic. My problem comes requirement 2 and a bit of 1. My consumer lives in a separate process from my server process so I need to a way of communicating the messages consumed to my server process. What would be the best way of doing this? Using a cache will require another process to read this cache for updates and that leaves me in the same situation as before. The fact that django code runs synchronously makes … -

Django with SPA?
First of all, greetings to everyone, I want to convert my project from MPA to SPA in Django, but I can't get the structure in my head. In the area you see in the photo, I want to redirect the base.html (or any field, for example login.html, register...) field to the app field in index.html during a user's first login to the site. html...) field in index.html during the user's first login, but I want to make it workable with the back and forth buttons in the web browser and manual input of the url. The .html pages are returned as a response as a string on the django side and I get the data with fetch. My problem here is that if the person manually enters the url on the login.html page, I redirect the login.html and the index.html is passed. If I first fetch the index.html with the load event and then fetch the login.html, I instantly display the non-css version and then it is fixed. Since the beforeunload event works without fetching the index.html, the DOM cannot find my app field because I did not redirect the index.html. If you have a constructive solution, I would appreciate … -

Combining django-jsonform with HTMX and CrispyForms resulting in removed interactivity after submit
I am using django to create a form that uses a JSONForm field from the django-jsonform package. I am using HTMX for asyncronous submission of the form and render_crispy_form for rendering the form back after it has been submitted. However, after submitting the form, the things inside the JSONForm are not shown anymore and the interactivity is removed for the django-jsonform field part. Here is my model: class GroceryStore(models.Model): PRODUCTS_SCHEMA = { "type": "array", "items": { "type": "object", "properties": { "name": {"type": "string"}, "price": {"type": "number"}, }, "required": ["name", "price"], } } creator = models.OneToOneField(User, on_delete = models.CASCADE) name = models.CharField(max_length = 200) products = JSONField(schema = PRODUCTS_SCHEMA, null = True, blank = True, default = None) The data is saved when valid data is submitted, the problem is just that it does not reflect it on the frontend. I am using this for generating the html to replace the form using HTMX: form_html = render_crispy_form(grocery_form) return HttpResponse(form_html) It says in the documentation that HTMX is supported. What could be the problem? -

is adding a table for video, image, and audio a good job for normalizing the database or not
I have an app that has a lot of videos, audios, and images about persons, events, diaries and so on. is it a good practice to having a distinct table for all types of multimedia to query over them and their information and detail fields or there is another good way to handle this mission. evenly, if this is a good solution for normalizing the database, or not? I explored into the net but did not see any complete description about if there is a way to distinct multimedia from tables and just pointing to them through using queries and joining tables, or this is the common way that professional developers do! -

How to change default Order from ASC to DESC in django OrderFilter
I am not an expert django dev. I was trying to write a viewset which has the ordering_fields and ordering fields, but this ordering field does not have any effect. My viewset is, class ContentViewSet(viewsets.ModelViewSet): queryset = Content.objects.all() serializer_class = ContentSerializer filter_backends = [OrderingFilter] ordering_fields = ['created_at'] ordering = ['-created_at'] What I am looking for is, it will provide the list in descending order. However, if I add a negative sign infront of created_at in the url, it gives me what I am looking for, but I was looking for a solution where I will get the same result without using that negative sign in the url. Thanks in advance. -
How to use DateField in an ArrayField in django
I'm trying to use ArrayField in my model. I get it working with, e.g., IntegerField, but not DateField. So I'm wondering, is there some limitation I'm not aware of, or is there a bit missing in my code that prevents it from working? In my models.py, I added the field with class Directive(models.Model): id = models.AutoField(primary_key=True) ... individual_dates = ArrayField( models.DateField(auto_now_add=False, blank=True, default=date.today), default=list,) test = ArrayField(models.IntegerField(blank=True), default=list,) ... and in my forms.py, I have class DirectiveForm(forms.ModelForm): individual_dates = SimpleArrayField( forms.DateField(), required=False, help_text='comma separated list of dates', widget=DatePickerInput(options={'format': 'DD.MM.YYYY'})) test = SimpleArrayField( forms.IntegerField(), required=False, help_text='comma separated list of ints') ... The form renders fine: Now, when I enter a comma seperated list of integers in the "test" field, the values are stored in the database as expected. when I try to enter a number of dates in the "individual dates" field using the DatePicker, every pick overwrites the previous one, and the last one is eventually stored in the database. when I enter a comma separated list of dates by hand, only the first entry is stored in database. But, when I use the django shell, import my model and try to enter dates there, it works as expected: >>> … -
