use django "include" inside a js function
I am doing a search page in which parameters are sent by ajax and then upon reception of the queryset I rebuild my cards. The whole thing is classic and working ok, here is a simplified version of the thing. Lots of lines killed or modified since it is not really the subject of the post let getobject = async (value,url) => { var res2 = await fetch(url, { method: 'POST', headers: { 'Content-Type': 'application/json', 'Accept': 'application/json', "X-CSRFToken": getCookie("csrftoken"), }, body: JSON.stringify({ value: value, }) }) let data2 = await res2.json(); videoitems.innerHTML = '' modalbin.innerHTML = '' data2["data"].forEach(async item => { if (item.ext == '.mp4') { const dynamicreation = async () => { let dyncontent3 = await createnewcard(item) let placing = await videoitems.appendChild(dyncontent3); } const nooncares2 = await dynamicreation() } else if (item.ext == ".pdf") { const dynamicreation2 = async () => { let dyncontent4 = await createnewcard(item) let placing2 = await videoitems.appendChild(dyncontent4); } const nooncares4 = dynamicreation2() } }) } the createnewcard function var createnewcard = item => { var dyncontent = document.createElement("div"); dyncontent.innerHTML = `<div class="m-2 extralarge-modal video${item.id}"> <div data-reco="${item.id}" class="extralarge-modal bg-white rounded-lg border border-gray-200 shadow-md dark:bg-gray-800 dark:border-gray-700"> <div class="p-5"> <p class="mb-3 font-normal text-gray-700 dark:text-gray-400"> ${item.title} </p> </div> … -

Running multiple independent docker containers for web services
I'm trying to run a few services on my server, by using separate docker image for each service: nginx - with a configuration for all available services below and access to the files on the server - should be always running Wordpress - for hosting a Wordpress web page (and probably PHP?) - will be almost always running on the server Django - for hosting a Django web page - will be sometimes running only Flask RESTful API - maybe in the future will be added I'm using docker-compose to configure nginx and django app, but I cannot run only nginx container without django (I've tried to use links and depends_on in docker-compose.yml). So long story short - I want to be able to add, run and stop containers for web services independently. -
In Django, is there a way you can limit a user to registering for an event only once?
I'm a newbie to Django, trying to build site to allow people to register for football matches. At the moment, a user can register multiple times for the same match, which is obviously not ideal! Is there a way that I can identify if the currently logged in user has already registered, and then replace the register button with a message telling them that they have already registered? I guess I need some kind of Boolean value in my EventDetail view, and then I can make a conditional statement in the template, but I'm unsure as to how to implement this. I hope this question is clear, it's my very first post! views.py: class EventDetail(View): def get(self, request, id, *args, **kwargs): event = get_object_or_404(Event, pk=id) registrations = Registration.objects.filter(event=event) total_participants = 0 for person in registrations: total_participants += 1 if person.guest: total_participants += 1 remaining_spaces = event.max_participants - total_participants template = "event_detail.html" context = { "event": event, "total_participants": total_participants, "registrations": registrations, "remaining_spaces": remaining_spaces, } return render(request, template, context) template {% extends "base.html" %} {% block content %} <p>{{ event.title }}</p> <p>{{ total_participants }} / {{ event.max_participants }} ({{ remaining_spaces }} spot{{ remaining_spaces|pluralize }} remaining!)</p> {% if total_participants < event.max_participants %} <a … -

How to use swagger_auto_schema decorator in django if the class based view does not have any serializer_class?
I have a class based view as: class DetailView(GenericAPIView): @swagger_auto_schema(responses={201: 'Created'}) @authorize(CustomPermission) def post(self, *args, **kwargs) -> Response: // code..... return Response(status=HTTPStatus.CREATED) First: The use of swagger_auto_schema without any serializer is throwing error as: AssertionError: DetailView should either include a serializer_class attribute, or override the get_serializer_class() method. And I don't want to use serializer for this endpoint as I don't need that. But the swagger_auto_schema keeps on throwing this error. I want to know whether there is any way to avoid the use of serializer and get the swagger documentation of this endpoint. Second: I also want to add authorisation of this endpoint in the doc. I know there is a security field in swagger_auto_schema, but don't know how to make it to use for my custom permission class ie CustomPermission Thanks. -

Why DAO is not used in most python web application like flask, django and sanic?
I've worked in lots of python web project. I also used flask, django and sanic to develop web applications and restful api services. Recently I heard DAO from my friend who writes both java and python code. Obviously DAO has its advantages but why I see no use of DAO (but most use ORM directly) in my past python web projects and similar projects in github? -
Dynamic URL's with multible layers
Im making a website using Django, where im making dynamic URLs. However i'm fairly new to programming and haven't been able to find out how to make dynamic URLs with more than 1 parametre. I'm making a site called "kartotek", which are user specific defined by the varible "kl_id", and therefore has a dynamic URL with following path: path('kartotek/<str:kl_id>/', views.kartotek, name="kartotek"), On this page, is there a button with which you choose a patient and come to another URL called "reg" with the following path: path('reg/<str:kl_id>/<str:pt_id>/', views.reg, name="reg"), I have the following code in views.py: def kartotek(request, kl_id): kliniknavn = Klinik.objects.get(navn=kl_id) E_patient = kliniknavn.patient_set.all() context = { 'kliniknavn':kliniknavn, 'E_patient':E_patient} return render(request,'DentHelp/kartotek.html', context ) def reg(request ,kl_id , pt_id): kliniknavn = Klinik.objects.get(navn=kl_id) ptid = Patient.objects.get(id_nr=pt_id) context = {'ptid':ptid, 'kliniknavn':kliniknavn} return render(request,'DentHelp/reg.html', context) I think the problem is the template code, which I'm kinda confused how to make, I was trying this: {% for patient in E_patient %} <a href="{% url 'reg' klinik.navn, patient.id_nr %}" class="btn btn-primary">Vælg patient</a> {% endfor %} Any have an advise? -

Forward slash "/" vs "os.path.join()" vs "joinpath()" for STATIC_ROOT and MEDIA_ROOT (Django)
I found there are 3 concatenation ways using forward slash "/", "os.path.join()" or "joinpath()" for "STATIC_ROOT" and "MEDIA_ROOT" as shown below and these 3 concatenation ways work properly for me. Forward slash "/": # "settings.py" STATIC_ROOT = BASE_DIR / 'static' MEDIA_ROOT = BASE_DIR / 'media' "os.path.join()": # "settings.py" STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_ROOT = os.path.join(BASE_DIR, 'media') "joinpath()": # "settings.py" STATIC_ROOT = BASE_DIR.joinpath('static') MEDIA_ROOT = BASE_DIR.joinpath('media') So now, which way do you recommend to use, forward slash "/", "os.path.join()" or "joinpath()" for "STATIC_ROOT" and "MEDIA_ROOT"? -

Forward slash "/" concatenation for STATIC_ROOT and MEDIA_ROOT (Django)

Aren't there any other types to concatenate with forward slash "/"? -
