Everything was working fine until I created a custom user for my django project and since then, time limit per user is no longer working but the expiry date for the token is working fine, I have been searching online to find any solution but I can find any so I'm stack and don't know how to go about it to fix it so I flush my database and do the makegrations and migrate again but none of them worked -
How to add clipboard module to QuillField() in django for using in django admin?
Copying and pasting are not handling correctly on the Quill Editor. Is there any additional instructions which are needed when using the QuillField() in django to properly enable it, specially for copying text documents with images? This is how I am doing it: class Post(models.Model): customer = models.ForeignKey(Customer,on_delete=models.DO_NOTHING,related_name='post_customer') title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) author = models.ForeignKey(User, on_delete= models.DO_NOTHING,related_name='posts_author') updated_on = models.DateTimeField(auto_now= True) created_on = models.DateTimeField(auto_now_add=True) asset = models.IntegerField(choices=POST_ASSET, default=0) status = models.IntegerField(choices=POST_STATUS, default=0) article = QuillField(blank=True, null=True) -
How would I perform post-setup init steps in Django?
Where would I put steps I'd like to perform AFTER Django's setup() call? I expected this would already be a Django signal (like post_migrate). It seems like making my own versions of get_wsgi_application, etc. with callbacks is the next best option. Since that code is rarely touched I can imagine that it could fail silently and no one would know why. For a little background, I'm making my own task runner on lambda using Django on Postgres. Being able to dynamically define scheduled python functions with their own arguments is a key feature. At start up, I need to connect database entries for functions and their definitions in code. The way I get around this problem today is at the image entrypoint: if not python_function_registry.is_registry_initialized(): python_function_registry.registry_setup() There are several places I do this today. It seems like there are several potential benefits to a post_setup signal (or something similar), so I expect it must already exist? Thanks for your help! -

Django admin restrict max inline forms by parent field
I have the following two models in Django. Model Contest has questions and Questions is another django model: class Contest(models.Model): min_questions = models.IntegerField() class Question(models.Model): contest = models.ForeignKey(Contest, on_delete=models.CASCADE, related_name="questions") question = ... Then I add the questions as an inline in the contest admin: class QuestionInlineForm(forms.ModelForm): class Meta: model = Question fields = \['question'\] class QuestionInline(NestedStackedInline): model = Question form = QuestionInlineForm extra = 1 inlines = \[AlternativeInline\] #Igonre this class CustomContestAdmin(NestedModelAdmin): inlines = \[QuestionInline,\] This let me create the questions inside the contests form, the problem is that I want to restrict the number of questions to create using the field min_questions of the Contest model, so that the form doesn't let me create a contest if the total amount of questions is less than the field min_questions. Is there a way to achieve this? I'm using the nested_admin library and I tried the method clean but the questions count shows as 0 because the questions have to be added after the instance of contest is created. I think this could be done by using transactions so I can create the Contest, then add the questions and before saving to the database check if the questions count is … -
Dynamic background change depending on the incoming link
I'm currently writing a site in django and I want to create a dynamic link page where the background depends on what comes from the link. I know I can make templates for each background, but I have over 500 of them, so this method seems inappropriate. Is there a better way to do it? I tried join static and dinamic paths and also send prepared path from backend but this both and some other way were unsuccessful at least in my code -

How to write a chatting app (dating app to be specific) in Python?
I'm trying to figure out how to get started with this because I'm not that good when it comes to programming, I did some projects in Flask but I don't know other frameworks. What I'm doing is a dating app where you create a profile and can message other users. I want the chat to be offline - to look like e-mails basically. I searched for some chatting app projects on GitHub, but the ones that met my needs weren't up to date (especially Django) and it was hard for me to try to change them. What framework would be the best choice here? Django seems like a good fit but like I said, I haven't coded in it. Is it possible to do it in Flask without it being too complicated? Do you have some examples that actually work without having to change the code? If you have any tips feel free to comment! -
Save selection from dropdown menu and display on a redirected page?
I am very new to django. I have a login page which allows you to select either Student, Admin, Instructor. How do I save the value selected and display it on the next page after you press Login? This is what I have so far. I believe my url routings are incorrect which is causing some sort of problem. Here is my file structure: Project file structure. This is what I have so far. In my login.html, I have a drop down menu where it classifies the selction as user_type. {% extends 'base.html' %} {% block title %}Login{% endblock %} {% block content %} <h2>Log In</h2> <form method="post"> {% csrf_token %} <label for="user_type">User Type:</label> <select name="user_type" id="user_type"> <option value="admin">Administrator</option> <option value="instructor">Instructor</option> <option value="student">Student</option> </select> {{ form.as_p }} <button type="submit">Log In</button> </form> <br> <a href="#">Forgot Password?</a> {% endblock %} From there, I need to get the value using a function in views.py. So I wrote this: ef login_view(request): if request.method == 'POST': user_type = request.POST.get('user_type') request.session['user_type'] = user_type return redirect('home') else: return render(request, 'login.html') I believe I also need to retrieve the value so I made another function in views.py def home_view(request): user_type = request.session.get('user_type') return render(request, 'home.html', {'user_type': user_type}) Then … -

Use BytesIO instead of NamedTemporaryFile with openpyxl
I understand that with openpyxl>=3.1 function save_virtual_workbook is gone and preferred solution is using NamedTemporaryFile. I want it to be done without writing to filesystem, only in memory, just like BytesIO did. Before update I had: wb = Workbook() populate_workbook(wb) return BytesIO(save_virtual_workbook(wb)) Now I need: wb = Workbook() populate_workbook(wb) tmpfile = NamedTemporaryFile() wb.save(tmpfile.name) return tmpfile As in https://openpyxl.readthedocs.io/en/3.1/tutorial.html?highlight=save#saving-as-a-stream As I'm using django probably I could use InMemoryUploadedFile but I don't want to. How can I use BytesIO or something similar in elegant fashion ie. without hacks and additional packages? -

Arabic characters are shown in a generated PDF as black blocks in a Django project using xhtml2pdf
I am building a Django/React project with mySQl database which has a collation utf8_general_ci. I want to generate a PDF based on given data in Arabic using xhtml2pdf. When I generate the PDF I find that the Arabic Characters are shown as black blocks or squares although I am using charset utf-8 in the HTML file and in the rendering function itself and I am using a font that is written in the official documentation of xhtml2pdf that it can be used for Arabic content. I have also used many other Arabic fonts but nothing worked. in utils.py: from django.http import HttpResponse from django.template.loader import get_template from xhtml2pdf import pisa from io import BytesIO from fpdf import FPDF def render_to_pdf(template_src, context_dict={}): template = get_template(template_src) html = template.render(context_dict) result = BytesIO() pdf = pisa.pisaDocument(BytesIO(html.encode("utf-8")), result) if not pdf.err: return HttpResponse(result.getvalue(), content_type='application/pdf') return HttpResponse('notworking') in views.py: from .utils import render_to_pdf import io from django.http import FileResponse from reportlab.pdfgen import canvas def ResultList(request): template_name = "frontend/thepdf.html" theentry = entry.objects.get(id = 2) return render_to_pdf( template_name, { "entry": theentry }, ) in thepdf.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html dir="rtl" lang="ar"> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <head> <style type="text/css"> @font-face {font-family: RTLFont; src: … -

Azure - Django deployment Static Files
I try to deploy my django app to Azure App Services. I create App in Azure and deploy my app to Azure. But when i open app i can't see staticfiles (images). However I can see it in locally. By the wat I use sqlite for the database. This is my settings.py file: STATIC_URL = "/static/" MEDIA_ROOT = os.path.join(BASE_DIR, 'static/images') MEDIA_URL = '/images/' STATICFILES_DIRS = [ BASE_DIR / 'static' ] # Deployment STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') And also this is urls.py file: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) # Deployment urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) First I fogot DEBUG=True, but I change it to DEBUG=False. It does not work also.
