Password protect page django
I would like to make a registration page for judges, but I would like to make sure that before entering the registration page you have to enter the password, each judge will have the same one that I will make available to them, he needs a simple page with one window to enter the password previously given by me. If someone would be able to say how I can create such a model and then its form, or if there is any other easier way, I will be grateful for any hints -

What is the best WYSIWYG editor to upload images and videos for Django
I've used Froala and its Django package (django-froala-editor), the first downside is Froala is not free and the second one is to upload videos. For images, it works like a charm but not for videos. Any suggestion for WYSIWYG editor for Django that supports image and video uploading out of the box? -
Local Variable Referenced Before Assignment Error Django
I am working on an eCommerce website. While saving billing and shipping information, I have a checkbox where user can input billing address and set is as the same shipping address. For that, I have used the instance of billing address which I have taken from the user and saved in the database when the user inputs the billing info. Since it is inside if statement, when I reference it in the shipping_address, it shows local variable referenced before assignment Error! I know why this error occurred, but unable to find how can I approach to solve it. I tried using global at the top of the function, but that too did not work. forms.py class CheckoutForm(forms.Form): # Billing Address billing_country = forms.ChoiceField( choices=COUNTRY_CHOICES, required=False) billing_address = forms.CharField(required=False) billing_address2 = forms.CharField(required=False) billing_zip = forms.CharField(required=False) # billing_phone = forms.IntegerField(required=False) # Shipping Address shipping_country = forms.ChoiceField( choices=COUNTRY_CHOICES, required=False) shipping_address = forms.CharField(required=False) shipping_address2 = forms.CharField(required=False) shipping_zip = forms.CharField(required=False) # shipping_phone = forms.IntegerField(required=False) # UTILITIES same_shipping_address = forms.BooleanField(required=False) set_default_billing = forms.BooleanField(required=False) use_default_billing = forms.BooleanField(required=False) set_default_shipping = forms.BooleanField(required=False) use_default_shipping = forms.BooleanField(required=False) models.py class Address(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) country = models.CharField(choices=COUNTRY_CHOICES, max_length=15) street_address = models.CharField(max_length=100) town_city = models.CharField(max_length=50) postcode = models.CharField(max_length=15) address_type = models.CharField(choices=ADDRESS_CHOICES, max_length=1) … -
Can we use multiple framework (both front end and back end) to build a website?
I am a newbie ( HTML CSS/ zero level ) to web development and when I search the internet there are literally tonnes of web framework for both front end and backend development.

How do I create a Django superuser in ssh?
I am deploying Django with PostgreSQL in Azure for a school project, per this tutorial. I am working with Django 2.1.2, and Python 3.7.5. In the "Run Database Migrations" step of the tutorial, I am instructed to open an SSH session and run the following commands: cd site/wwwroot source /antenv/bin/activate python manage.py migrate python manage.py createsuperuser When I run the 'createsuperuser' command, I expect a prompt for a username, email address, and password, but I am not prompted for any of these. Instead, the SSH session prompts me for another input: (antenv) root@62a62185684a:/home/site/wwwroot# As such, I am unable to log in to my Django installation. When I attempt a login, I receive the following error message: The traceback is at the end of this message. I expect to be able to create a superuser in Django, and use that superuser account to configure the app. Instead, I receive the ProgrammingError message and am unable to proceed. Any help would be gratefully received. I have Googled the various error message, searched StackOverflow, and searched YouTube for tutorials, and I have reached a roadblock.

Best way to do simple API calls between Django server and android application?
I'm building a system where I store a Member model on a Django server, one of the attributes of Member is score which is what I want to change using API calls. My question is what would be the best way to do this? I looked into the Django REST framework but it seems a bit overkill for what I'm trying to do.

Outline of what I need is below iOS/Android app makes request sending pk and score to add to total server updates appropriate model instance and returns True/False to app depending if save was successful -

CSS file isn't applying to the page, not loading under sources
I was trying to link a css file to my html, and for some reason the css won't load in. Below I'll supply the html and css code. When I open the page source, the css href works fine, I can click on it and it takes me to the css file, but when I inspect I can see that the css file is not part of sources. I've tested my code on JSFiddle and it works fine there, as well as on the snippet here. I also tried pressing ctrl + f5 and shift + f5 to refresh the page without caches, but nothing changed. So I don't know what else to do to fix this. I've been doing it on Chrome so I tested it real quick on Firefox but still, no changes.

Join two sets of data of the same table in django

usage of ('/') in the following django code

Save successfully validated form fields when other fields fail
I have a rather long form including validation which I would like users to fill out. If the user submits the form successfully then it is saved to the db. I am aware that some users may attempt to submit the long form, only to have it raise validation errors, then leave my site and return to complete it later. I would like the form fields which are successfully validated to be saved (or is it possible to have them save automatically without the user needing to press the submit button?) so if the user exits the site they can later return and only have the fields which failed validation blank, not the entire form. views.py def needs_analysis(request): if request.method == 'POST': form = PersonalInformationForm(request.POST, request.FILES, instance=request.user.personalinformation) if form.is_valid(): form.save() return redirect('enrolment-index') else: form = PersonalInformation(instance=request.user.personalinformation) context = { 'form' : form } return render(request, 'enrolment/personal_info.html', context) Thank you. -
"FieldList" with foreign objects
Let's say I have cars running in different races. I want an ordered list in Race with the cars that will run. The problem is I want to manually modify that list from admin interface. class Car(models.Model): id = models.CharField(max_length=16, primary_key=True) class Race(models.Model): title = models.CharField(max_length=255) start_grid = models.ForeignKey(Car,on_delete=models.CASCADE) I have read many posts about ordering on related ForeignKey based on some filters like creation date or so, but this particular case requires to define a manual order. Don't exist some kind of models.ListField so my solution is to create a list of related Car ids and store JSON string in Race. But feeling that is not a good idea How can I create a field that contains an ordered list of foreign objects/id and be compatible with modify the order from admin interface? -

Django non-static content not rendering
I'm using kubernetes and containers. nginx ingress controller. Also nginx container is serving up static content. The landing page (static) works just fine (checked with incognito, no caching). Soon as I go to a page that requires rendering something from the backend, it times out. I logged into the containers and cannot see any immediate issues in the log files or elsewhere. I shut down all the containers and started them fresh. Still nothing from the Django side is responding. Here is my nginx config (in Kubernetes/yaml format): apiVersion: v1 kind: ConfigMap metadata: name: nginx-config data: nginx.conf: | events { worker_connections 1024; } http { server { access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; listen 8080; server_name localhost; location ^~ /.well-known/acme-challenge/ { default_type "text/plain"; } location /static/ { autoindex on; alias /code/core/static/; include /etc/nginx/mime.types; } location = /favicon.ico { access_log off; log_not_found off; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:8080/; } } } I can't tell what the issue is.
