What is more flexible way to organize User authentication model in Django?
I've started working on a new project and I would like to know what is more flexible and changable (improvable) way to work with User model? At first I want to make my project oriented towards employees of the company to allow them manage products and other entities. And then I want to expand the project by letting customers to register in the system and buy stuff. But of course I want employees and customers to have different fields and restrict customers from having access to certain parts of the system. Django offers two ways of dealing with Users: it's either Substituting a custom User model or Extending the existing (default) User model. I can't decide what way to go to have two kinds of users in the future. -
My Django code (forms and models) works just fine, but It's definitely a bad choice for large amounts of data. Would appreciate suggestions
this code works just fine when registering users and adding them to the database. With additional code in the template, it also shows the users that their chosen username/email already exists pretty well. However I am mostly certain that this code's quality is very bad, since It woudn't work well with large databases, since I search for all the users and their usernames/email. Then again, I don't know how to add better validation. I decided to add these validators(passwords excluded) because, unique=True in models have no effect on the forms. What I mean is, before these codes, if I registered with the same username and email over and over, if the passwords matched, the last password that I entered got added to the database(user number stayed the same), but form was considered valid (I think) and It didn't show any errors to the user. This is the best I came up with, but I'm pretty sure it's a bad one. I am taking any suggestions, what other kind of validation can I add to fix the mentioned problem. I thought unique=True would fix things, but apparently it's not enough. Note that I am also a beginner and if this question … -

Django: Global Exception Handler
I'm looking to create a global exception handler in a Django project. I've looked into the DRF middleware, but I want to capture all unhandled exceptions from functions in my project not just from requests/response, and log the details of the error(line, function, etc.). From there, I tried overriding sys.excepthook in manage.py but the traceback shows that it was invoked by manage.py. It does not show the actual function that caused the error. in manage.py: def exception_hook(exc_type, exc_value, tb): logger = logging.getLogger('django') logger.error(sys.exc_info(), exc_info=True) if __name__ == '__main__': sys.excepthook = exception_hook main() LOGGING in settings.py: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'standard': { 'format': '{levelname}; {asctime}; {module}; {filename}; {funcName}; {message}; {lineno}; {exc_info}', 'style': '{', }, }, 'loggers': { 'django':{ 'handlers': ['file'], 'level':os.getenv('DJANGO_LOG_LEVEL','INFO'), 'propagate': False, } }, 'handlers':{ 'file':{ 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': 'debug.log', 'formatter': 'standard' } } } Is there a way to do this properly or is the code missing something? -

A table of MySQL database asociated to Django App is "corrupted"
I have problem that has never happened to me before. It is an application made with Django that has never given me errors. For some reason, a table in the database (MySQL) is corrupted, but the app is still working. However, when I make a call like this: queryset = Tuition.objects.filter(agent = user) Then, the database gives me this error: django.db.utils.OperationalError: (1712, 'Index base_tuition_agent_id_b1b4dfb6_fk_base_staff_user_ptr_id is corrupted') But, if I change the call to: queryset = Tuition.objects.filter(Q(date__lte="1900-01-01")|Q(agent__id=90)) Then, There is no error... Surprise! (Obviously in the database there is no date prior to 1900 so both functions are similar). But, if I change the call to: queryset = Tuition.objects.filter(Q(date__gte="1900-01-01")&Q(agent__id=90)) Then, the database through the error again... So: If I filter by "agent" doesn't work. If I filter with an "OR" conditional combining the "agent" field with another one it works. If I filter with an "AND" conditional combining the "agent" field with another one doesn't work. You can see the details of the table here: I don't know much about MySQL and would like to know how the result of the above calls is possible. Because from my ignorance, the normal thing would be that none of them work, or well, … -
Django: How to use OuterRef() for .get() in annotate?
I am using django-treebeard and use a model that allows recursive relations. So, I need to count the number of my descendants using .annotate(), but To get it, you need to go through .get() once, as shown below. However, in that case, OuterRef("pk") does not seem to work and the following error occurs. This queryset contains a reference to an outer query and may only be used in a subquery. What can I do to solve this problem? queryset.filter(post=post) .annotate( reply_count=Count( Comment.objects.get( pk=OuterRef("pk") ).get_descendants() ) ) -

POST Request to HTTPS(SSL) url from Android/Java
I am pretty new to Java and Android. Working on Python all the time. I am trying to make an Android Apps via Android Studio BumbleBee (2021.1.1 Patch 3) that can make GET and POST request to a https(SSL) server. The server is run by Django 3.2, deploy on IIS(version 10.0) powered by Window Server 2019. GET requests are fine but POST requests are not! What i am trying to do is to make a POST request to login to the website. My idea is to send a GET request to obtain the csrftoken and csrfmiddlewaretoken for subsequent POST request. (From my understanding, Django POST requires csrfmiddlewaretoken in the POST data and csrftoken in the cookies). Everything works fine when i tried on http://localhost:8000 OR i use @csrf_exempt decoration on both HTTP and HTTPS(SSL) server. But the actual server which run by Django is HTTPS(SSL) instead of HTTP and i want to remain the csrf function. Since i keep failing on Android Studio, I tried to make POST request to https by Java(on Eclipse IDE Version: 2022-03 (4.23.0)) and it keeps returned an error of 403. I tried with SSL Socket Factory in Java but still it does not work. … -

How can I do a redirect in Django and React?
