Django, get the all posts from the Theme
Sorry for english. I have a Themes and there are posts in this themes. I need to get the posts from the current Theme I tried to get a theme via slug then check the theme id and display all posts under that id, but i dont know how template_name = 'site/themes.html' def get_context_data(self, **kwargs): context = super(MultipleModelView, self).get_context_data(**kwargs) context['modeltwo'] = Theme.objects.all() context['modelone'] = Subject.objects.all() context['modelthree'] = Theme.objects.filter(slug=self.kwargs.get('slug')) context['modelfour'] = Post.objects.filter(where_we_are_id = 1) return context Model Theme title = models.CharField(max_length=50,verbose_name="Название") subject = models.ForeignKey(Subject,on_delete=models.CASCADE,related_name='subject') slug = models.SlugField(null=True,verbose_name='ссылка на страницу') class Meta: ordering = ['title'] verbose_name_plural = 'Темы' verbose_name = 'Тема' def __str__(self): return self.title def get_absolute_url(self): return reverse('article_detail', kwargs={'slug': self.slug}) Model Post class Post(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE,null=True,blank=True) title = models.CharField(max_length=50,verbose_name="Название") text = models.TextField(max_length=500,verbose_name="Текст") created_at = models.DateTimeField(auto_now_add=True, verbose_name='Дата создания') is_published = models.BooleanField(default=True) where_we_are = models.ForeignKey(Theme,on_delete=models.CASCADE,related_name='get_news',null=True,blank=True ) class Meta: ordering = ['created_at'] verbose_name_plural = 'Посты' verbose_name = 'Пост' def __str__(self): return self.title ``` -
Django: how to save model into different database tables depending on which ManyToOne relationship it belongs to?
I'm new to Django. My app have two models, Customer and Order, where each customer can have multiple orders. So what I did is to set up a ForeignKey(Cusotmer) relationship in Order model: name = models.CharField(max_length=20) phone = models.CharField(max_length=20) def __str__(self): return self.name class Order(models.Model): customer= models.ForeignKey(Customer,null=True, on_delete = models.SET_NULL) ordername = models.CharField(max_length=20) In this case, if I want to query the orders by a specific customer customer1, I can use Order.objects.filter(Customer=customer1). But I wonder if it is possible to save the order data for each customer in a separate database table? Right now all the orders are saved in the same table and misuse of filters can let customers view other customers' orders. -
Adding email in Django's admin user creation

Dependency references a non-existing parent node ('auth', '0012_alter_user_first_name_max_length')
I'm working on a Django project on PyCharm and it runs totally fine. I am using a venv and I had to send the project to a person. So I removed the venv folder and sent and they encountered this issue (see image). I deleted my migrations (except init.py) and executed manage.py makemigrations and manage.py migrate and the project runs fine on my end. The dependency is automatically created (so it isn't something I created manually) and still exists after deleting and reapplying migrations but I had no issue in running the server on my end. This is what is in my first migration file: class Migration(migrations.Migration): initial = True dependencies = [ ('auth', '0012_alter_user_first_name_max_length'), ] operations = [ May I know what the issue might be for the other person? Is it because I deleted the venv folder? Can I just remove this dependency on my end? Will this make the server run fine on the other person's end without them having to make any changes? Any help is appreciated! -

React, Django: Build Files are not using STATIC_URL
I'm using React + Django. When I run it locally, everything works fine because my static files both from my Django-side and from React are loaded through /static/. When I run npm build run, the index.html in my React file does not change to the production setting's STATIC_URL. Instead, it still shows something like this: <body> <noscript>You need to enable JavaScript to run this app.</noscript> <div id="root"></div> <script src="/static/js/asdfasdf.chunk.js"></script> <script src="/static/js/asdfasd.chunk.js"></script> </body> Is there a way I can set the script's src attribute to something like {% static chunk.js %}? Or is there a better angle to do this? -
Django Rest Framework permission_classes not working
I have a problem using Django Rest Framework's permission_classes attribute. The view I want to protect is defined as: class Test(APIView): permission_classes = [IsLoggedIn] def get(self, request): return Response("aaa") I have also tried having the class inherit GenericAPIVIew. permissions.py from rest_framework import permissions class IsLoggedIn(permissions.BasePermission): def has_object_permission(self, request, view, obj): return False I'm trying to get the permission to at least always refuse the request, but it seems that the has_object_permission method is never getting called. -

Django 404 Error page not found...the current path matched the last one
I'm new to django and I'm playing around with my own variation of the polls tutorial. My app was working fine, every page loaded correctly. Then I made a single change; I created and then deleted a model. Now, many of urls seem broken. And I don't understand this error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/polls/1/pick/ Raised by: polls.views.pick Using the URLconf defined in mySite.urls, Django tried these URL patterns, in this order: polls/ [name='index'] polls/ <int:pk>/ [name='detail'] polls/ <int:pk>/results/ [name='results'] polls/ <int:question_id>/vote/ [name='vote'] polls/ <int:question_id>/tally/ [name='tally'] polls/ <int:question_id>/pick/ [name='pick'] The current path, polls/1/pick/, matched the last one. You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. So I don't understand why it says both that: The current path, polls/1/pick/, matched the last one. and also page not found? How does that work? And what could have caused this when the app was working fine previously? My urls.py: from django.urls import path from . import views app_name = 'polls' urlpatterns = [ path('', views.IndexView.as_view(), name='index'), path('<int:pk>/', views.DetailView.as_view(), name='detail'), path('<int:pk>/results/', views.ResultsView.as_view(), name='results'), path('<int:question_id>/vote/', views.vote, name='vote'), path('<int:question_id>/tally/', views.tally, name='tally'), path('<int:question_id>/pick/', … -

GitHub Actions - Build Docker Image From Latest Branch
I'm new to dev ops and am trying to figure out how to create an automated pipeline that is triggered when our team pushes to the staging branch of GitHub. Right now, I've almost got everything, in that, when we push to staging, we ssh into our server, pull the build, stop the running container, and then start a new one. My only issue right now is that I'm not exactly sure how to pull the docker image from a specific branch on GitHub. I want to do the equivalent of git pull and then restart the docker container. Right now, I've got: - name: Pull new image run: ssh staging 'sudo docker pull ${{ secrets.AWS_ECR_REGISTRY }}/simple-django:latest' - name: Stop running container run: ssh staging 'cd code_folder; sudo docker-compose down -v --remove-orphans' - name: Start new container run: ssh staging 'cd code_folder; sudo docker-compose -f docker-compose.prod.yml up -d --build' but I'm not sure exactly where ${{ secrets.AWS_ECR_REGISTRY }}/simple-django:latest is/what it corresponds to. Does this pull from some sort of GitHub branch? Or do I have to be able to log in as an admin to the AWS server to check out what this corresponds to. Thanks -
Django, React: Static Files with Elastic Beanstalk + S3
I have a standard Django project structure with a React app: main_app settings.py asgi.py etc... tickets models.py views.py etc... react-frontend public/ src/ etc... In react-frontend in the main template index.html, I am loading my static files like so: <!DOCTYPE html> <html lang="en"> <head> {% load static %} <meta charset="utf-8" /> <link rel="icon" href="{% static 'favicon.ico' %}" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="description" content="Web site created using create-react-app" /> <link rel="apple-touch-icon" href="{% static 'favicon.svg %}" /> <link rel="manifest" href="{% static 'manifest.json' %}" /> <title>Main App</title> </head> <body> <noscript>You need to enable JavaScript to run this app.</noscript> <div id="root"></div> </body> </html> When this page appears on my production server, the {% static file/directory %} is loaded fine. However, the JavaScript chunks that npm run build creates is not; they're not loaded with the static path to the S3 bucket, instead being loaded with the standard /static/path/to.js. Is there a way I can have my JavaScript that's added in through npm run build be set to my S3 bucket just like I would with {% static dir/file %}? -

I have a subprocess thats using the call function to run some data collection function. When I run it without shell it will get stuck within a loop and never complete its task. With shell=True it completes its task and doesn't get stuck.
