Overriding Django LoginView
I am writing a new authentication template to use with my Django apps. I am basing this on a tutorial which I followed. The tutorial uses the built-in authentication views for password resets which I would like to keep, but I want to customise it slightly. I have an attribute on the user accounts called "disabled" which allows a user to login. On the login view I would like to get it to check to see if the account is disabled, "locked", before allowing the login. For the reset password view I would like to get it to unlock the account if successful. An example of the path looks like: from django.contrib.auth import views as auth_views urlpatterns = [ path('accounts/login/', auth_views.LoginView.as_view(), name='login') ] The account model looks like: class Account(AbstractBaseUser, PermissionsMixin): email = models.EmailField(unique=True) name = models.CharField(max_length=150) phone = models.CharField(max_length=50, blank=True,null=True) date_of_birth = models.DateField(blank=True, null=True) picture = models.ImageField(blank=True, null=True) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=True) date_joined = models.DateTimeField(default=timezone.now) last_login = models.DateTimeField(null=True) disabled = models.BooleanField(default=True) hash = models.CharField(max_length=128,default=hex(random.getrandbits(128))) objects = AccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] def get_full_name(self): return self.name def get_short_name(self): return self.name.split()[0] Do I import this into views and override it there? Is someone able to post a … -

Can't connect to Postgres db remotely when deployed on GCP
So I'm not sure what code to include that might help so let me know and I can add it. I have a Django web app that I'm deploying on Google Cloud Platform. The app has you search a zip code, then call the Yelp API, adds what it returned to a DB, then pulls from the DB to display in the template. This works perfectly when running locally with a SQLite DB. I've created a Postgres DB and that seems to be working when running locally through cloud_sql_proxy as well. The problem is when deployed it will only search what is already in the DB but cannot add to it. If you search for a zip code that's not already in the DB it returns 500 server error. You can try for yourself HERE. Zip codes 78626 and 55075 work because that's what i tested it with when running locally. if I run locally and do another zip, then deploy, that zip will suddenly work. Please let me know if there's anything i can provide for more context. -

I've got a Django site with authentication handled by Auth0 (following this quickstart guide).

Somehow link them with current Django-based users perhaps? -
django return 404 uploading media file
hi I have a problem when I upload a file to the deployed server. It returns 404 does not matter if I do it by admin or by a view but if I can see the files that are already on the server.

Not JSON Serializable Django Session
In my django view, I have the below: manifestData = form2.cleaned_data form2 is a formset which will have a dynamic number of forms within it. So in one instance it may have just one form, but in a different case it might have 3 or 5, etc, etc. For example, if it contains 2 forms and I execute print(manifestData) I will get the output: [{'ProductCode': <Product: APPLES-1>, 'UnitQty': u'11', 'Price': u'11.00', 'Amount': u'121', 'DescriptionOfGoods': u'Washington Extra Fancy', 'Type': u'Cases', u'id': None, u'DELETE': False}, {'ProductCode': <Product: ORANGES-1>, 'UnitQty': u'1', 'Price': u'12.00', 'Amount': u'12', 'DescriptionOfGoods': u'SUNKIST ORANGES', 'Type': u'Cases', u'id': None, u'DELETE': False}] Next, in my view I am trying to pass that manifestData to another view via the session like so: def quoteView(request): ... request.session['manifestData'] = x return redirect('QuotePreview') class QuotePreview(View): def get(self, request, *args, **kwargs): manifestData = request.session.pop('x', {}) ... However I get an error on this line request.session['manifestData'] = x which mentions "APPLES-1 is not JSON Serializable". I believe this is because this is a foreignkey reference to a product model. class Product(models.Model): ProductCode = models.CharField(max_length=100) HSCode = models.CharField(max_length=50, null=True) DescriptionOfGoods = models.CharField(max_length=100) Price = models.CharField(max_length=100) UnitType = models.CharField(max_length=100) def __str__(self): return str(self.ProductCode) Question is primarily - how can … -

nginx/1.14.0 (Ubuntu) 404 Not Found (api call)
I am running a frontend app using Vuejs and backend app with django. I am able to successfully serve both backend and frontend on the same ip using separate nginx server blocks i.e. /etc/nginx/sites-available/frontend_app and /etc/nginx/sites-available/backend_app. Both apps are also enabled.

How can I be sure that the request is being sent by Stripe and not by a third party?
I am working on my application with the Django backend and the Angular frontend and I am gonna use Stripe. At this point everything seems to be working properly. It looks something like shown below. I would like to be sure that I do everything properly and in a secure way. I found Best practices for using webhooks and there is recommendation about adding @require_POST and @csrf_exempt decorators. I guess that I do not need them because Django automatically handle requests other than POST method in my Generic API View and there is also no problem with CSRF so it seems to me that I do not have to disable CSRF protection? I have also doubts how can I be sure that the request is being sent by Stripe and not by a third party? Let's say we have scenario that someone creates an account in the form on the page with amount equals to 10000$ and it goes through the first card verification. He does not have sufficient funds in his account and the transaction is declined however he sends a fake request to my my_stripe_url/ endpoint with status invoice.payment_succeeded. The question is whether Stripe supports it by default … -

django with heavy computation and long runtime - offline computation and send results
I have a django app where the user sends a request, and the server does some SQL lookup, followed by computation on results and finally showing the results to the user. The SQL lookup and the computation afterwards can take a long time, maybe 30+ minutes. I have seen some webpages ask for email in such cases then send you the URL later. But I'm not sure how this can be done in django or whether there are other options for this situation. Any pointer will be very helpful. (I'm sorry but as I said it's a rather general question, I don't know how can I provide a min runnable code for this) -
Apscheduler calling function too quickly
Here is my scheduler.py file: from apscheduler.schedulers.background import BackgroundScheduler from django_apscheduler.jobstores import DjangoJobStore, register_events from django.utils import timezone from django_apscheduler.models import DjangoJobExecution import sys # This is the function you want to schedule - add as many as you want and then register them in the start() function below def hello(): print("Hello") def start(): scheduler = BackgroundScheduler() scheduler.add_jobstore(DjangoJobStore(), "default") # run this job every 10 seconds scheduler.add_job(hello, 'interval', seconds=10, jobstore='default') register_events(scheduler) scheduler.start() print("Scheduler started...", file=sys.stdout) My Django app runs fine on localhost. I'm simply attempting to print 'hello' every 10 seconds in the terminal, but it sometimes prints like 3 or 4 at a time. Why is this? This was just a base template to help understand apscheduler.
