ValueError: Field 'X' expected a number but got 'X'
So I was working on some fields in my models.py and ran a python3 manage.py makemigrations and python3 manage.py migrate. A few minutes later I decided to get rid of one of the fields, and replace it with something else - however, everytime I try to migrate and makemigrations, the error that Field 'X' (which is deleted) expected a number but got 'X'. Anyway around this considering my field is deleted? The exact error is: ValueError: Field 'randkey' expected a number but got '1AB2CD'. -

Routing URLs between Django and Angular
I'm currently creating a website in Django and Angular. Django is serving the Angular build files. Excluding /api calls, all URLs are returned a template that loads the Angular index. This part works. The part I'm having trouble with is when I try to lazy-load modules. Angular will try to find a module foo at localhost:8000/foo-module.js, but it's really at localhost:8000/static/mydjangoapp/angular/foo-module.js. I know I could solve this problem by setting <base href="/" /> in index.html to <base href="/static/mydjangoapp/angular" />, but I want the frontend to be served from /. I could also avoid lazy-loading modules, but I feel like there's a better way to serve Angular from Django using which I can lazy-load. How can I get Angular to properly fetch the URLs? I'm also having a similar issue with serving Angular assets. -
django send response to website without changing it
This is what the form looks like right now This piece of code gets the input and has a rough IF statement that confirms if the confirm pasword input == password input, if not it redirects you and sends an http response that passwords do not match, now instead of an http response what i want to do is send a message without changing the website that confirm password == password like a little message that says passwords do not match while you type or after you press submit. views.py def get_data(request): username = request.POST.get('username', None) email = request.POST.get('email', None) password = request.POST.get('password', None) confirm_password = request.POST.get('confirmpassword', None) try: #validate the email validate_email(email) if confirm_password == password: # confirm password a = Account() a.username = username a.email = email a.password = password a.save() return HttpResponse('User %s has been registered.

Django key, value dictionary returning data under the same key
I'm pulling post data from my firebase database and trying to pass it into my template in Django. I can easily pass just the values into the template but I'm trying to also pass the ID using a key-value dictionary but for some reason, I can't get it to work the way I want it to. It's returning all the values under the same key I would like each key to match the relating value.

how to correctly import urls.py from app?
This is probably pretty simple but I can't get my head around it. I'm learning Django, have v3.0.4 installed and can't get the URLs from an app to work correctly. On the project urls.py I have the following: Project\urls.py: from django.contrib import admin from django.urls import path from django.urls import include from AppTwo import views urlpatterns = [ path('', views.index, name='index'), path('', include('AppTwo.urls')), path('admin/', admin.site.urls), ] I've created an app named "AppTwo" and have the following urls.py and views.py in the app: AppTwo\urls.py: from django.urls import path from . import views urlpatterns = [ path('/help', views.help, name='help'), ] AppTwo\views.py: from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("<em>My Second App</em>") def help(request): return HttpResponse("<em>Help Page!!!</em>") If I browse to http://127.0.0.1:8000/ the index page loads and I see the text "My Second App" as expected. However if I browse to http://127.0.0.1:8000/help I get page not found 404 error. I can also browse to the admin page just fine. So far this is a stock project, the only other change I made after creating it was to the settings.py file to install the "AppTwo" application.

Django 3 and jQuery - sort <li> items on all paginated pages
Currently I can sort li items on one page but not all paginated pages. I select an item from a dropdown list to sort by various attributes based on a model. Here is the jquery for one of the items.

Append information to queryset to sort
I have Book and and Reader models, and each of them have m2m relationship with Author and Genre. For any given book, I have a function that iterates over all readers and calculates a likely_to_read score (from 0 to 100, details of how it's calculated aren't particularly relevant). I'd like to now have this function return a list of readers sorted by likely_to_read from highest to lowest, that also includes the calculated score, but I'm not sure what the best way of achieving this is. I know I can create a local dictionary that stores just the reader_id and likely_to_read score, and then reverse it by score and have another queryset where id__in=<ids>, but I'm wondering if there's some way to 'extend' the queryset with this score? -
What's the purpose of setting "X-Forwarded-For" header in nginx
I have the following Nginx configuration for my Django application: upstream api { server localhost:8000; } server { listen 80; location / { proxy_pass http://api; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location /staticfiles { alias /app/static/; } } I based this config on a tutorial here. After some research, looks like setting the Host header allows the Django API to determine original client's IP address (instead of the IP address of the proxy). What's the point of the X-Forwarded-For header? I see a field called $http_x_forwarded_for in the nginx logs but I'm not sure it's related. -

Clear entire cart with one button click - Django/Python
