Ajax call in Django to see if user already exists

However, it is not working. When I start typing in the field, it is telling me email address already exists. Am I doing it the right way?

Check if user had filled questionnaire before with Django

Django redirect user upon login failure at /complete/auth0/
I'm using Django with Auth0 for authentication. Sometimes the login fails on Auth0 and redirected to my Django server with /complete/auth0/ with a token indicating error. This reaches my backend at the AUTHENTICATION_BACKENDS class, calling the function auth_complete, which calls process_error. This throws an exception and reaches the http500 page. The question is how should I handle that within these functions? How can I redirect the user to some page (e.g /login_failed.html) to show the client and them decide what to do -

Pyinstaller for Microservice architecture to support multiple services to one Executable file
We are developing an application driven by a microservices architecture. Django as ORM to the Mobile Application and the database. We additionally have about 4 more python micro-services communicating through WebSockets. We are trying to make these 4+1 ( 4 microservices and 1 Django application ) into one executable file. We are able to make our Django application an executable file separately but not as an integrated architecture. The other 4 microservice files are all pure python code and they communicate using WebSockets as mentioned already. Additionally, we have a caching system by Redis and a data pipeline system by RabbitMq. Is there a way to integrate them all together to one python executable file using PyInstaller or maybe any other method? Let me know if the question is not clear, I will try to explain better than this. -

Python - How do I get classes that rely on each other to be defined in the same file?
I have the following code used in Django: from django.db import models from django.contrib.auth.models import AbstractUser # Create your models here. class User(AbstractUser): groups = models.ManyToManyField(group) class group(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name="course", null=True) name = models.CharField(max_length=50) description = models.CharField(max_length=300) def __str__(self): return self.name I made this code to get a user model in django that allows for more fields. However, the new user class requires the group field since a user can join many groups. This is causing an error since the group is defined after class. What do I do to fix this issue? What I really need is just a way to add extra fields to the default User class so I tried it like so from another SE post. -
Django Todo App - Filter by foreign keys results in TypeError

django models without primary key and id
I use two primary keys. In database, this does not result in duplicate errors unless both values are duplicated. But I don't know how to solve this problem in django model. When the primary key is removed and used, an id column is created. But I do not want this. Using unique_together results in an error because the primary key is duplicated. Is there any way to solve this problem? -

Receiver function not answering after Signal.send in Django
I'm trying to create a simple twitter bot that recieves info from different API's and posts the tweets based on the info. I'm using a Django for this (not sure if completely needed, but I'm just trying to learn the framework) so I created 2 different apps, one that recieves the information from the API and creates an object (so far this object is just a quote) and send it to another app which handles the twitter publication. The general idea is that my quote app will generate a signal which will be sent to the posting app where I created a function with a receiver decorator so it will be listening all the time. Nevertheless, for some reason the decorator is not working and after sending the signal I get no response. This is the creation of the signal: from django.dispatch import Signal new_quote = Signal(providing_args=['author', 'content']) This is the sending of the signal: quote=Quote.objects.create(author=author, content=content) new_quote.send_robust(sender=quote, author=author, content=content) The object is being created with no problem, already check that. And this is the catching of the signal. from .models import Post from django.dispatch import receiver from quotes.signals import new_quote from quotes.models import Quote @receiver(new_quote, sender=Quote) def post_tweet(Quote, **kwargs): … -

"Confirm Form Resubmission " on pressing back in the chrome browser in my django project
This is my first web development project. It is basically an e-voting website. The index page is the login page. So, when the user login using valid credentials, the website will take the user to the voting page where that contains a voting form and some other options like feedback, news updates, etc. in the Navigation bar. The login request is "POST". The vote submission request is also "POST". Here, if the user presses other option like submitting feedback or viewing the candidates, will take the user to that respective pages. And if the user presses the back button, the website should take him to the voting page again where he can again use other facilities voting, viewing candidates, or submit feedback. But the problem I face is if the user presses the back button from the 3rd page i.e., feedback page or viewing candidates page, it shows an error "Confirm Form Resubmission". Help me fix this bug.
