So, I need to pass quantity to a corresponding form to be able to select quantity of books while adding them to a cart. Note that quantity is a Book model IntegerField.

Do I need to backup a database after an upgrade?
I am using python and Django for my project. I have upgraded PostgreSQL version from 9.6 to 10. Before that, I made a backup of my database. ./manage.py dumpdata > db.json After a successful upgrade, I had no idea whether the database will intact. But upon checking, I found the database was okay. I think it is necessary to backup before an upgrade, but do I need (or recommended) to load the backup data back to the cluster again? Or is there any recommended way of upgrading the database. -
Is there any way to use elasticsearch with mongoengine?
I've got Django project using mongoengine. Large part of it uses aggregation pipeline queries to perform complex document search. I want to use elasticsearch in this project to speed up the search, but mainly for educational goal. I know that haystack is a good way to use ES in django projects, but it works with Django ORM only. So is there any way to use ES with mongoengine django apps? -

Django admin 2.0 - Make a file downloadable in change view
I have a table with a FileField and some other attributes with information about the file. Currently, when i click on a row it sends me to the change page for that row, which has a link to visualize the FileField, which is a .txt file. I managed to make it display via the browser on click, but what I want it to do is to intercept the click event and return an HTTPResponse to let the user download it. How can I do that? -

Can I get Django model objects as singletons?
When I call Models.get() for the same id it returns different Python objects: print(Book.objects.get(id=1) is Book.objects.get(id=1)) >>> False I wonder if it is possible to change this behavior, maybe with some custom Model Manager. It could internally store some registry for all retrieved objects and override get_queryset() to make it use objects from this registry if they have already been retrieved. Why do I can be helpful I have a model ServerCredentials which stores login and password. I have multiple consumers that connect using the same credentials. Since only one connection to server is allowed, it would be convenient to store transient connection information (e.g. auth token) as a field of ServerCredentials object, but not in database. If model objects could be singletons, consumers could easily share auth tokens just by using a field of ServerCredentials. Without it, I have to make some registry manually, but I fell that it should be done on ModelManager's side. Is it a possible to cache objects in a registry on ModelManager's side? Is it a good idea? Are there implementations for that? Many thanks in advance! -

Server side Framework vs Client side Frameworks
So I've recently been learning Django and it took me a while to understand that it was a Server side framework, I had previously only worked with Vue/AngularJS and I assumed Django was similar because of the same offers (for loops, if statements etc...). Relating to that note, what does Django actually offer that Vue/etc do not? Are client-side frameworks really only useful to produce SPA's? -
Django admin site customization
I am new to django. I have searched a lot, but none of them solved my problem. I want to override admin site templates only and not functionality (only some UI enhancements). Most of topics said to create a new directory in root named templates and inside it, create an admin folder and inside that, copy the base_site.html from current admin directory. base_site.html that is copied: {% extends "admin/base.html" %} {% block title %} test new admin UI {% endblock %} {!-- I have changed this, but it is not applied --} {% block branding %} <h1 id="site-name"><a href="{% url 'admin:index' %}">{{ site_header|default:_('Django administration') }}</a></h1> {% endblock %} {% block nav-global %}{% endblock %} and in my index.html, I cannot extend this base_site.html (it is not recognized by my IDE at all!) and in my settings.py I have: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ 'templates/admin', os.path.join(PROJECT_PACKAGE, 'templates'), ], 'APP_DIRS': True, . . . . . . . . . . . }, ] then I copied index.html from the admin folder and changed it a bit, but the previous admin templates are still loaded (even changing base.html in my new admin directory was not applied to loaded admin … -
Proper usage of viewset queryset
According to Django REST framework documentation, the following two code snippets should behave identically. class UserViewSet(viewsets.ViewSet): """ A simple ViewSet for listing or retrieving users. """ def list(self, request): queryset = User.objects.all() serializer = UserSerializer(queryset, many=True) return Response(serializer.data) def retrieve(self, request, pk=None): queryset = User.objects.all() user = get_object_or_404(queryset, pk=pk) serializer = UserSerializer(user) return Response(serializer.data) class UserViewSet(viewsets.ModelViewSet): """ A viewset for viewing and editing user instances. """ serializer_class = UserSerializer queryset = User.objects.all() But the way I interpret it, in the first case the query User.objects.all() is run with every api call, which in the second case, the query is run only once when the web server is started, since it's class variable. Am I wrong ? At least in my tests, trying to mock User.objects.all will fail, since the UserViewSet.queryset will already be an empty Queryset object by that time. Someone please explain me why shouldn't the queryset class argument be avoided like pest and get_queryset be used instead ? -
Django Channels Frontend and Backend Integration
From what I understand, the frontend and backend are integrated via APIs where the frontend calls on the APIs built by the backend. How does this work when we use Django Channels? I am assuming that it works conceptually the same, where the frontend opens a websocket that calls on an API that is linked to the consumer class in the consumer.py file via the routing.py file. This is similar to Django's DRF where frontend calls on the API that links to views.py via the urls.py file. My question is: In Django's DRF, we could check if the APIs are working by literally typing the API in the browser. How could we check if the routes are working for Django channels? For example, in Django's official tutorial, the API for the websocket to the consumerclass is: ws://127.0.0.1:8000/ws/chat/lobby/ We can't exactly type this in the browser as they use different protocols -- Browsers use HTTP and websockets don't...right? So how would we check that the routes and django channels that we have build from the backend would work in the frontend when it is called in the html files? Because in projects, frontend and backend components are developed as separate projects, … -

how class based views know that they need to call dispatch method
We know that dispatch is the first method that is called when our url hits the CBV(Class Based Views). We also know that to call these views we have to call as_view() with our CBV in our urls.py to make them callable. views.py is shown below class ProductListView(ListView): template_name = "products/list.html" model = Question #Question is a model that is defined in models.py urls.py is shown below urlpatterns = [ url(r'^$',ProductListhView.as_view(),name='list'), ] Now my question is 1. How the CBV(ProductListView) knows that it has to call dispatch() method since we only inherited a generic views class but haven't mention anywhere to call dispatch()? -

Insert python string into Django template context with markup
If I render a static image in the .html template it works. But if I provide the static markup string as dictionary value to the template (the context), it will not work. It seems to be something to do with string formatting and not allowing me to use {% %} the way I need to. I have tried: 1. .format() 2. escaping the percent characters 3. raw strings 4. concatenation 5. autoescape 6. | safe and a number of other things Basically, I am constructing a multi-line string in view.py with '''{% %}''', and then rendering a template with this string as the context.
