How to structure django + react project for deployment?
I'm building a django + django-rest-framework project with react as frontend. I've look around for the best way to structure and deploy it and it seems there are several aproaches. One is to build the react frontend as static files and have django serve them, another one is to have 2 diffeernt servers and let both projects comunicate over http. Which is the better option? What are the pros and cons of each aproach? It seems the latter one would be more expensive since we have to pay for both servers. Notes: The project is realatively small but can end up evolving into a larger one. We are using a MySQL database We want the option to use the django admin webpage -

How to display two separate lists of two different models declared in ListView in one HTML template in Django?
I have coded a ListView for search engine. I wanted to extract data from fields of two different models. First, I declared separate lists for each model. Then I combined them into one list as shown below. view.py class SearchView(ListView): template_name = 'articles/search_view.html' def get_queryset(self): query = self.request.GET.get('q') object_list = Article.objects.filter(Q(title__icontains=query) | Q(description__icontains=query)| Q(body__icontains=query) | Q(stocks_etfs_or_bonds__ticker__icontains=query) | Q(stocks_etfs_or_bonds__description__icontains=query) | Q(stocks_etfs_or_bonds__name__icontains=query) | Q(tags__name__icontains=query)) securities_list = StockETFBond.objects.filter(Q(name__icontains=query)) search_result = list(chain(object_list, securities_list)) return search_result In this case, the template will display one list of two models. search_view.html template now {% for object in object_list %} {{ object }} {% endfor %} But I would like to be able to display two separate lists of two different models in the template as shown below. search_view.html {% for object in object_list %} {{ object }} {% endfor %} {% for object in securities_list %} {{ object }} {% endfor %} How can I do it? -

debug setting is ignored when I move my django project to docker compose
we have a Django application. Right now we run it using Ubuntu 18.04 on Vagrant. Everything works fine. Now we have decided to move to docker compose. We have set everything and all is great and running. The only problem is that we have a very weird bug with the debug value. So, we have DEBUG=True in our settings file. We pass that value to the configuration template to use come includes in html. To do that, we have the following settings: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates". # Always use forward slashes, even on Windows. os.path.join(PROJECT_DIR, 'templates'), ], 'OPTIONS': { 'debug': DEBUG, 'loaders': [ # List of callables that know how to import templates from various sources.

Django adds an extra "/" in the url?
Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/products/1// Using the URLconf defined in products.urls, Django tried these URL patterns, in this order: [name='home'] contact/ admin/ products/ [name='product-list'] products/ products/ <int:id>/ [name='product-detail'] products/ <int:id>/delete/ [name='product-delete'] products/ about/ The current path, products/1//, didn’t match any of these Why does it require an extra slash after the id? The more I deal with it, the more slashes it wants. I have urls.py like this: from django.urls import path from .views import ( product_detail_view, product_create_view, render_initial_data, dynamic_lookup_view, product_delete_view, product_list_view) app_name = 'product' urlpatterns = [ path('', product_list_view, name='product-list'), path('', product_create_view), path('<int:id>/', dynamic_lookup_view, name='product-detail'), path('<int:id>/delete/', product_delete_view, name='product-delete'), path('', product_detail_view), ] Also another urls.py with something like this: urlpatterns = [ path('', home_view, name='home'), path('contact/', contact_view), path('admin/', admin.site.urls), path('products/', include('product.urls')), path('about/', about_view), ] Here's the function: def dynamic_lookup_view(request, id): #obj = Product.objects.get(id=id) #obj = get_object_or_404(Product, id=id) try: obj = Product.objects.get(id=id) except Product.DoesNotExist: raise Http404 context = { 'object': obj } return render(request, "products/product_detail.html", context) So it raises the exception because it was looking for the additional "/", but where did it come from? -

Handling dynamic IP in Django ALLOWED_HOSTS with nginx

I'm running my setup in AWS Lightsail Containers, where I have three containers running: nginx django nextjs When publishing a new release on my AWS Lightsail instance it runs fine for a few minutes, then I hit a 503 error, which causes the instance to reboot - run a few minutes then reboot again. Looking at the logs I can see that the health-check failed, and django throws and error saying that I should add the request IP to the allowed hosts: [28/Aug/2021:13:56:23] Invalid HTTP_HOST header: 'x.x.x.x'. You may need to add 'x.x.x.x' to ALLOWED_HOSTS.

Why data from table is not recieving in djagno?
When i tried to retrieve data from table it is not showing any thing without giving error message. This is my model class staff(models.Model): id = models.AutoField name = models.CharField(max_length=250) role = models.CharField(max_length=250) salary = models.CharField(max_length=250) address = models.CharField(max_length=250) number = models.CharField(max_length=250) date = models.DateField() This is my views file def user(request): staffs = staff.objects.all() params = {'staff': staffs} return render(request, "salary/user.html", params) and this is my template <td> 02312 </td> {% for staff in staffs %} <td>{{ staff.name }} </td> {% endfor %} <td> $14,500 </td> -
Simplifying Django Query Annotation
I've 3 models and a function is called many times, but it generates 200-300 sql queries, and I'd like to reduce this number. I've the following layout: class Info(models.Model): user = models.ForeignKey(User) ... class Forum(models.Model): info = models.ForeignKey(Info) datum = models.DateTimeField() ... class InfoViewed(models.Model): user = models.ForeignKey(User) infokom = models.ForeignKey(Info) last_seen = models.DateTimeField() ... . I need to get all the number of new Forum messages, so only a number. At the moment it works so that I iterate over all the related Infokoms and I summerize all Forums having higher datum than the related InfoViewed's last_seen field. This works, however results ~200 queries for 100 Infos. Is there any possibility to fetch the same number within a few queries? I tried to play with annonate and django.db.models.Count, but I failed. Thanks. -
