Django save post via celery
I have a particular use case where i write text for a blog post in admin dashboard. Then i want to generate the embeddings of post. I am doing this in admin.py @admin.register(Post) class PostAdmin(admin.ModelAdmin): list_display = ('title', 'author', 'created_at') readonly_fields = ('embeddings_calculated','emebddings_updated_at') def save_model(self, request, obj, form, change): if not obj.meta_title: obj.meta_title = obj.title obj.meta_description = obj.content[:160] super().save_model(request, obj, form, change) print("django post id",obj.id) post = get_object_or_404(Post, id=obj.id) print("django post title",post) if not change: # if new post not an edit post task_id = perform_task.delay(obj.id) result = AsyncResult(str(task_id), app=app) print("AsyncResultx", result) print("AsyncResultx_state", result.state) here is my celery task @shared_task() def perform_task(post_id): print("celery post id",post_id) post = get_object_or_404(Post, id=post_id) print("celery post title",post) I am getting this error django.http.response.Http404: No Post matches the given query. Though the print statement such as django post id and django post title show me correct result. But the issue lies in celery. I cant see celery post title in console. I aslo tried task_id = transaction.on_commit(lambda: perform_task.delay(obj.id)) But it did not work as well. Without celery every thing work well, but i want to use celery. -
Django retrieves wrong datetime objects (timezone overridden) from postgres database
I am using: psycopg==3.1.18 Django==4.2.10 PostgreSQL 16.1 I use a DateTimeField on a Django model which created a timestamp with timezone in postgres If I create a new object of that model with passing a timezone-aware datetime, save it to the DB, it gets created correctly. With that I mean, when i connect to the DB with a viewer like pgadmin or datagrip, the datetime is correct. But when i get the data back in django, they have the wrong offset. It seems like it overrides the Offset to 0 (UTC). The time is still the same, which is the problem. Exmaple: I pass to the model: 2024-02-18 01:46:29+01:00 In the database (viewed with DataGrip) the following is stored: 2024-02-18 01:46:29.000000 +01:00 When i get the object in django, it is: 2024-02-18 01:46:29+00:00 So the time is not the same anymore, because instead of reading the time just in the UTC Timezone, it take the time in the UTC+1 timezone but changes the timezone to UTC I have set the following in settings.py USE_TZ = True TIME_ZONE = 'UTC' I have tried playing around with the TIME_ZONE setting in the DATABASE Variable (settings.py) Setting it to 'TIME_ZONE': 'Europe/Zurich', resulted in … -

Error when connecting Angular app with REST-Django service
I have an web application deployed on GKE. Front-end service is Angular 17 app running on Official NginX Docker container Load Balancer with Ingress. Backend is REST-Django service running on Gunicorn running on Official Python container. The problem is when I want to reach the service (GET method) from Angular I get error Reason: CORS request did not succeed in Firefox browser - Chromium says net::ERR_NAME_NOT_RESOLVED. The Django service has installed CORS: INSTALLED_APPS = [ ... 'corsheaders', ...

From Angular's pod/container I am able to curl the Django service and it responds in desired way. -
Django: Transform an object into an object of a derived model class
In Django I've got a model class M1 and class M2 which is derived of M1. In the database this is generated as two tables T1 and T2 where T2 points to T1 like this: T1.id = T2.T1_ptr_id So far so good. Now it might be that in the database the entry for for T2 is missing sometimes - and I would like to create this entry on the fly by changing M1 to M2 in Django. I have tried this, but it (obviously) fails: m2 = M2(pk=m1.id) Furthermore I don't want to create a new instance of M2 - i want to transform M1 into M2. Is there a way to do this? -

Django polls tutorial part 3, template is able to load Question model text but not related Choice model
I'm currently on the third part of the official Django polls tutorial. Have a problem where when I load the template detail.html, question_text from the Question model is being rendered fine but choice_text(s) are not. The browser shows the correct amount of list bullets as but the text is not there. Here is the template I am trying to load: <h1>{{ question.question_text }}</h1> <ul> {% for question in question.choice_set.all %} <li> {{choice.choice_text}} </li> {% endfor %} </ul> The associated view function is: def detail(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(request, "polls/detail.html", {'question': question}) The models are defined as: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField("date published") def __str__(self): return self.question_text def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text polls/1 the Question model with two Choices related to it is rendered as text from Questions model rendered correctly but elements from Choice model are not I expected the related Choice objects obtained from {% for question in question.choice_set.all %} to display onto the HTML page as list elements. Instead only the bullets show up without the text. Would really appreciate any help! -
Wagtail: How to filter children of index page, when index page is accessed through foreign key
I apologize for any mistakes, English is not my native language. I am making site with news and events of multiple organizations (each organization has their own account allowing them to create news and events by themself). Using the news as an example: NewsIndexPage is parent for all NewsArticlePages. Each NewsArticlePage is linked with organization. At url /news/ NewsIndexPage shows all news and allow to filter news by organization with RoutablePageMixin (/news/organization/<str: organization_slug>/). Also each organization has their own landing page (OrganizationPage) with organization's info and news section. News section shows up to 3 latest news of organization (like in bakerydemo repository, when latest 3 blog entries is listed in HomePage: https://github.com/wagtail/bakerydemo/blob/1d9247f0f516dd842da995b1d67fadcd7d644f7d/bakerydemo/base/models.py#L305 https://github.com/wagtail/bakerydemo/blob/1d9247f0f516dd842da995b1d67fadcd7d644f7d/bakerydemo/templates/base/home_page.html#L30). Each OrganizationPage references NewsIndexPage through ForeignKey. But I don't know, how to filter children of NewsIndexPage when it accessed through ForeignKey. When I access OrganizationPage instance I want to pass organization's slug to linked NewsIndexPage so I can filter children NewsArticlesPages. The only thing I came up with is to create template_tag that will pass slug as an argument to some kind of get_news_articles(self, organization_slug) function. But I haven't been able to do that yet. news.models: class NewsArticlePage(Page): """ A news article page. """ image = models.ForeignKey( … -

DRF: Serialize field with different serializers and many=True
I have the following models in my django rest framework app: class Question(models.Model): class Type(models.TextChoices): TEXT = 'text', 'text question' RADIO = 'radio', 'choosing one option quesiton' CHOICE = 'check', 'choosing multiple options question' type = models.CharField(max_length=5, choices=Type.choices) title = models.CharField() description = models.TextField(blank=True, default='') def __str__(self) -> str: return f'{self.type}: {self.title}' class TextQuestion(Question): answer = models.CharField() class RadioQuestion(Question): variants = fields.ArrayField(models.CharField()) answer = models.CharField() class ChoiceQuestion(Question): variants = fields.ArrayField(models.CharField()) answers = fields.ArrayField(models.CharField()) class Test(models.Model): name = models.CharField() creator = models.ForeignKey(User, on_delete=models.CASCADE) questions = models.ManyToManyField(Question)``` I want to write serializer for test serialization, but I dont know how to serialize questions field. Because I have different serializer for every question type: What should I do? Maybe it`s better to reorganize my models somehow? I already writed serializers for all question types: class TextQuestionSerializer(serializers.ModelSerializer): class Meta: model = TextQuestion fields = '__all__' class RadioQuestionSerializer(serializers.ModelSerializer): class Meta: model = RadioQuestion fields = '__all__' class ChoiceQuestionSerializer(serializers.ModelSerializer): class Meta: model = ChoiceQuestion fields = '__all__' I thought about using serializer.SerializerMethodField() but it this doesnt work with many=True -
How to implement of social login with dj-rest-auth and getting redirected back to frontend which uses vanilla js with sessionid and token cookies set
I'm currently implementing social login with dj-rest-auth with a custom provider. I have went through plenty of sites but most tutorials/resources don't show how to implement the frontend, so I'm unsure how to implement it. The frontend can only use vanilla js and is a SPA. My current idea/testing is with a href=127.0.0.1/api/auth/callback which will run the function callback. If a code is not return it'll redirect to the authorize url to obtain one and proceed to be redirected back to the same function to start login. After logging in then redirect to homepage with all relevant cookies. REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.TokenAuthentication", 'rest_framework.authentication.SessionAuthentication', ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], } Provider login api (http://127.0.0.1:8000/api/auth/provider/) auth/views.py redirect_uri = 'http://127.0.0.1:8000/api/auth/callback/' def callback(request): if 'code' in request.GET is None: socialapp = SocialApp.objects.get(name='provider') authorize_url = (f'{settings.OAUTH_SERVER_BASEURL}/oauth/authorize' '?client_id=' + socialapp.client_id + '&redirect_uri=' + quote(redirect_uri, safe='') + '&response_type=code') return redirect(authorize_url) if 'code' in request.GET: socialapp = SocialApp.objects.get(name='NAME') code = request.GET['code'] context = {} context['grant_type'] = 'authorization_code' context['client_id'] = socialapp.client_id context['client_secret'] = socialapp.secret context['code'] = code context['redirect_uri'] = 'http://127.0.0.1:8000/api/auth/callback/' try: token_response = requests.post('https://provider-api-link/oauth/token', json=context) data = token_response.json() # access-token is inside if 'error_description' in data: print("error_description_post_code:", data) social_login_response = requests.post('http://127.0.0.1:8000/api/auth/provider/', json=data) response = HttpResponseRedirect('/') response.set_cookie("Authorization", 'Token … -

Django logout view shows a blank page and does not log out a user
I faced an issue with my logout view. I created a custom CBV that inherits from the default Django LogoutView. The interesting fact is that it works perfectly fine with the FBV.

I have also created a template that is visualized without any problems with the FBV.

How to run a Python Django app designed with HTML

I'm struggling to learn Django Framework
How do I learn Django? I understand python basics such as functions, classes etc. I'm trying to learn Django for more than six months. Actually I understand the concept a little but it seems I've not learnt anything at all as I cannot memorize every nuts and bolts of Django framework. I'm feeling so frustrated nowadays. It's may not be relevant but want to mention that I'm 39 years old. Why I'm so struggling? Is it because of my age as my brain has become slow? Or I'm skipping something? Here I want to mention that I understand the basics of html and CSS. I've not learnt JavaScript yet. Thanks. I've tried a number of books and YouTube videos. I'm spending one or two hours to learn the framework everyday. But I'm seeing no progress.
