Issue With Anchor Tags Not Scrolling Far Enough in Django
I have a Django model called "prompt" that has particular properties, and I have linked these prompts to certain paragraphs (paragraph is another model) in the database depending on whether I want to display that prompt with that paragraph. Before I had starting displaying the prompts on the webpage alongside the paragraphs, my anchor tags inside the "sidebar" area worked properly and scrolled to the correct section of the page, but after I added in the prompts from the Django database, the anchor tag "jumping" functionality stopped working properly. Here is my code: {% extends 'prompt/base.html' %} {%block title%} Guidebook for Prompting {%endblock%} {%block content%} Guidebook on Prompting for Language Learning {%endblock%} {%block sidebar%} <div class="ml-3 mb-16 grid grid-cols-4 gap-4"> <div class="pb-6"> <div class="col-span-1"> <ul> {% for section in sections %} <li id="section{{section.id}}" class="py-2 px-2 rounded-xl"> <a href="{%url 'section:detail' section.id %}" class="section-link">{{section.section_title}}</a> <ul> {% for paragraph in section.paragraph_set.all %} <!-- here is the section where the links are--> <li id="paragraph{{paragraph.id}}" class="ml-3"> <a href="{%url 'section:detail' section.id %}#paragraph{{paragraph.id}}">{{paragraph.paragraph_title}}</a> </li> {%endfor%} </ul> </li> {%endfor%} </ul> </div> </div> <div class="space-y-10 mr-24 text-5xl col-span-3" id="section-text-container"> {{section.section_title}} <div class="mt-10 text-lg"> {{section.section_description}} </div> {%for paragraph in section.paragraph_set.all%} <!-- jump here --> <div id="paragraph{{paragraph.id}}" class="mt-10 text-3xl">{{paragraph.paragraph_title}}</div> <div class="text-lg">{{paragraph.paragraph_text … -
Content security policy blocking CKEditor write function in from bundled script in Django website application
In my Django website application, I am using CKEditor 5.1.1 and a bundled script is being blocked by my script-src directive in my content security policy. The offending file is bundle-5f73f48756.cms.ckeditor.min.js. Specifically, the write(a) function from the block of code below is being flagged in the console: write: function(a) { this.$.open("text/html", "replace"); CKEDITOR.env.ie && (a = a.replace(/(?:^\s*<!DOCTYPE[^>]*?>)|^/i, '$\x26\n\x3cscript data-cke-temp\x3d"1"\x3e(' + CKEDITOR.tools.fixDomain + ")();\x3c/script\x3e")); this.$.write(a); this.$.close() }, I have tried writing middleware (with the help of ChatGPT) to address the issue. I have successfully done this with other popup or inline scripts but in this case, the middleware does not work. The goal there was to inject my nonce into the script tag from the replace() function but nonetheless, the error persists. ChatGPT also suggested editing the configuration for CKEditor. However, since it is a "site-package" I am not sure where in my Django project I can actually update or override the configuration. For context, the path to my base.py (settings) file is marketing/marketing/settings/base.py -
Pycharm debugging does not stop at breakpoints when starting Django server on docker-compose

I could create the root index.html page but could not create another page in Django
I have made a simple Django design in which I displayed a database for Medical blood test items. I successfully made the typical three files (views, the app URLS, and the basic URLS) as follows: Views.py from .models import Test from django.shortcuts import render def index(request): tests = Test.objects.all() return render(request, 'btestinfo/index.html', {'tests': tests}) def contact(request): return render(request, 'btestinfo/contact.html') App URLS from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), # path('<int:test_id>', views.detail, name='tests_detail'), path('contact/', views.contact, name='contact') ] Basic URLS from django.contrib import admin from django.urls import path, include urlpatterns = [ path("admin/", admin.site.urls), path("btestinfo/", include("btestinfo.urls")), path("contact/", include("contact.urls")) ] I exhausted all my tricks to create a link like http://127.0.0.1:8000/contact in order to display the contact.html page, am always ending up with the error: ModuleNotFoundError: No module named 'contact' I was only able to display the the db items from the link http://127.0.0.1:8000/btestinfo.

How to set cachecontrol for different types of image differently without overriding get_object_parameters using django-storages
I have multiple apps and each app has different cachecontrol requirement. get_object_parameters provides us. But it will be big change for codebase. Instead is it possible to pass cachecontrol to constructor e.g S3Boto3Storage(**options = { 'bucket_name': 'abc', 'querystring_expire': 172800, 'cachecontro': 'max-age=12000', 'location': 'LINTING', }) Right now its not working need to add this functionality in package. -

How do I integrate xAPI or cmi5 in my Django application?
I have all the user's activity data like course completion data, course topic completion data, time spent on each topic and course, assessment data in MySQL database. But, I couldn't find the documentation/tutorial on integrating cmi5 (with/without xAPI) into Learning Management System platform built using Django web-framework.

Download CSV using AJAX in Django - saved file contains the view content instead of the csv content
I'm dynamically generating a CSV from some content, and want to provide a message to the user and then download the file. When using Javascript, the file that's downloaded is the HTML of the view, and not the CSV. If I remove the javascript, the CSV is downloaded, but then there is no indication of this to the user. How can I get the CSV when using javascript? One thing I note is that I see a GET after the POST in my Django application log when using the javascript script. I am following https://docs.djangoproject.com/en/4.2/howto/outputting-csv/ to generate the csv content, and got the javascript from the answer in Django cannot download docx file in ajax This view content works when used without the javascript components - a csv file is downloaded. def csv_report(request): if request.method == "POST": report_dates_form = AllMemberseventForm(request.POST) if report_dates_form.is_valid(): start_date = report_dates_form.cleaned_data.get("start_date") end_date = report_dates_form.cleaned_data.get("end_date") events = Events.objects.filter(event_date__range=[start_date, end_date]).order_by("event_date") if events and len(events) > 0: response = HttpResponse( content_type="text/csv", headers={ "Content-Disposition": 'attachment; filename="%s"' % filename, "filename": filename, "event_count": len(events), }, ) writer = csv.writer(response) for event in events: writer.writerow( [event.thing, event.otherthing, event.event_date] ) return response My javascript in the template that the view uses is as follows. … -
Django + Mongo + djongo. Trouble with adding new models with ForeignKey
i use django + mongo with djongo. I have 2 models: Deck and Card; class Deck(models.Model): deckName = models.TextField(max_length=100) deckDetail = models.TextField(max_length=1400) class Card(models.Model): cardName = models.TextField(max_length=100) cardDetail = models.TextField(max_length=1400) deckCard = models.ForeignKey(Deck, on_delete=models.CASCADE) dailyCard = models.BooleanField(default=False, unique=True) when i add new Deck model with http://127.0.0.1:8000/admin/app/deck/add/ (django admin standart) it's ok. But when i add new Card model i have "Exception Type: DatabaseError at /admin/app/card/add/ Exception Value: " ; in py manage.py shell i create 2 new models (card, deck) and it's ok! I think the point is that when saving the Card, the string (id) is passed to the deck field, but do you need int? Or something like that? Do I really have to make my own admin page and override the methods for saving models there? -
Django Model Queryset Calculation
For example class Rice(models.Model): quantity = models.DecimalField(...) Lets say: rices = Rice.objects.all() for i in rices: i.quantity This gives output as : 5 7 9 10 Now what i want to achieve is a total_quantity till that object is reached what my desired output should be : 5 12 21 31 Logic: First object total_quantity till that object is calculated is 0+5 then, next object total_quantity is 0+5+7 then 0+5+7+9 and so on. And this should be done using (queryset) annotate/aggregate or any other db models functions. (If not possible then any other way) If the order changes the the output should also change. -
How does has_module_permission work with inline models in django admin
While there are other ModelAdmin methods that can be used to hide inlines, it's noted here that the InlineModelAdmin also shares the has_module_permission feature with ModelAdmin. It works perfectly on ModelAdmin objects as described in the docs but I don't seem to understand how it works or is supposed to work for InlineModelAdmin objects. class HideModuleAdmin(admin.ModelAdmin): def has_module_permission(self, request): if condition: # This works as expected. Hides it from the menu items return False return super().has_module_permission(request class HideTabularInlineModelAdmin(admin.TabularInline): def has_module_permission(self, request): if condition: # This does not work as expected. The inline is visible places I don't expect to see it return False return super().has_module_permission(request I am simply inheriting the above where I need them e.g class SomeModelAdmin(HideModuleAdmin): pass class SomeTabularInline(HideTabularInlineModelAdmin): pass -
Using Cookiecutter Django Docker backup functions on a Windows machine
I have used Cookiecutter Django to create a dockerized project, which I have deployed to production. I can use the commands for backing up, checking backups, and restoring all fine on my production server, which is a linux machine. I was hoping to move the backup from my production environment to my development environment, which is a windows machine, however using the commands throws an issue "/usr/bin/env: ‘bash\r’: No such file or directory". I've searched around and seen this is a windows files encoding issue but can't find an answer which works for me for resolving that issue. Has anyone faced this issue before and found a workaround? Thanks for any help anyone can offer! -

How to give a client a JWT while a redirection?
I'm working on a web app in django, and I'm facing a problem in implementing a JWT authentication. I have a django application which is responsible for user management and therefore authentication. So when I authenticate a user in my view, I have to redirect him to the home page which is in another django application. But here is the problem, when I authenticate a user, I create a JWT and pass it to the response so that the client of the user can store it, but it seems that when redirecting, the client cannot store the JWT. Here is the view that authenticate the users : def loginUser(request: HttpRequest): """ Request : URL : /user/loginUser/ Method : POST Content-type : application/x-www-form-urlencoded Required informations : -username -password Response : Status : 302 Redirect url : /home """ if request.method != "POST": return JsonResponse( data={"error":"Bad request method."}, hearders={"Allow":"POST"}, status=405, ) try: username = request.POST["username"] password = request.POST["password"] except KeyError: return redirect("/user/loginPage/?error=Missing informations") user = authenticate(username=username, password=password) if user != None: exp = datetime.datetime.now() + datetime.timedelta(hours=3) exp = int(exp.timestamp()) payload = { "user_id":user.id, "username":user.username, "exp":exp } token = jwt.encode(payload=payload, key=JWT_KEY) response = HttpResponse(status=302) response["Location"] = "/home" response["Authorization"] = "Bearer "+str(token) return response … -

Django Local Host works but hosting servers don't
I'm really new to programming. I had to make a web application with Django, so I made a weather app. It works fine if I run it locally with runserver but I tried various hosting websites and none work. This is my GitHub Repository. I hope anyone can help me. Various hosting websites. Want my application to work online but it doesn't.
