Is django-allauth suitable for large scale applications?
recently I have come across a fairly large scale project which requires me to connect with google and facebook for login. It seems it can be easily done using django-allauth which is a third party package. I would like some experienced wisdom on the following questions: 1. Regarding safety: Is it safe to use the package on my application as my client has security at the utmost priority. 2. Regarding licences: Is it free to use commercially or will I have to purchase specific licenses. I am a beginner in the web development world so I apologize if my questions seem silly. -
How can I run a chronometer on my django host webpage?
I'm trying to insert a chronometer into my webpage, so that when a button is clicked they will have certain time to solve certain challenges. This chronometer should be unique for the hole server (anyone who can get inside will see this chronometer) and it has to be global for all the views in my web. I'm using Django. I can't find information about this, I know how to make chronometer, but how can I run it on my server and put it on all the views of my website. Thank you! -

Django filter parent where ALL child values meet criteria
Based on these models: class Job(models.Model): status = models.CharField(max_length=30) class Task(models.Model): job = models.ForeignKey('Job', related_name='tasks') status = models.CharField(max_length=30) I need a query that returns each Job where Job.status is null and ALL child Task.status's are "COMPLETE". For context, when all Task.status's are complete, a comparison between values in each sibling Task will occur, it should not be carried out until all siblings Task is set to "COMPLETE", so the query will return those that are complete. -

Creating a webclient to send and receive emails
I have to create a webclient to send and receive emails from gmail and outlook accounts. It should be able to run directly in a browser with any setup on the computer. Here are the important details: I have planned to use imaplib and smtp library in python. It will be a django project. I will use react for the frontend. And mondodb to store some data in a database. And aws for deployment. The webclient will be used by approximately 10 people. The webclient will have many functionalities not available in other clients. So my question is, Is it possible to create such webclient or am i missing anything like protocols, security or hardware requirements? You might find this question as not exactly related to programming, but it is important for me to get an answer. As I am new to djando and mongodb, i want to make sure that I don't waste my time trying to create something which is not possible. -

Handling multiple types of users in Django
I am building a django app that will need to have two types of accounts (Merchant and Buyer), not that it matters but just to provide more context, on my sign up page, I have a radio button to let the user choose if they want to register as a Merchant account or as Buyer account, and each account type will have a separate sign in page to login to the website. I was thinking of using this approach. Please ignore discrepancies in the code, it was simplified just for the question. class User(AbstractBaseUser): first_name = models.CharField() last_name = models.CharField() date_joined = models.DateTimeField(auto_now_add=True) is_active = models.BooleanField(default=True) class Merchant(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(unique=True) ph_number = models.CharField() class Buyer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(unique=True) As you can see each account can have unique fields like the ph_number so I came up with this approach after some research. Question 1 While inheriting AbstractBaseUser I need to have a uniquely identifiable field to assign to USERNAME_FIELD, in my case I don't really have one for the User, so what do I use here? I intend to have two custom authentication back-ends to use the email field from the Merchant … -
