'NoneType' object is not iterable' when using chrome browser
I get this error: 'TypeError at /' with the exception value: ''NoneType' object is not iterable' when i run my Django project on my local host. This only occurs when i'm specifically using the chrome browser ONLY. When i run my local host on safari, there are no issues. I am pretty certain that my code is not at fault, because i was running it, and closed my laptop, and when i opened up my laptop again, it gave me this error, and i had not changed a single line of code. Also i'm sure that its not my code because it is working on safari as i have stated earlier -
Django URL with blank parameter
I am new to Django. I created a Django web app wherein after a user logs in, it will redirect to the basic_list template which contains a list of wines. In the basic_list template, there is a “manage account” button which will redirect to the manage_account template. However, when I click the manage account button, it loads to localhost:8000/manage_account// instead of having a parameter such as localhost:8000/manage_account/1/ if 1 is the pk value of the user who just logged in. What should I do? Any suggestions would be greatly appreciated. models.py from django.db import models class Wine(models.Model): name = models.CharField(max_length=300) year = models.IntegerField() objects = models.Manager() def __str__(self): return str(self.pk) + ": " + self.name class Account(models.Model): username = models.CharField(max_length=20) password = models.CharField(max_length=20) objects = models.Manager() def __str__(self): return str(self.pk) + ": " + self.username urls.py from django.urls import path from . import views urlpatterns = [ path('', views.view_login, name='view_login'), path('login', views.view_login, name='view_login'), path('basic_list', views.view_basic_list, name='view_basic_list'), path('manage_account/<int:pk>/', views.manage_account, name='manage_account'), ] views.py from django.shortcuts import render, redirect, get_object_or_404 from .models import * from django.core.exceptions import ObjectDoesNotExist def view_login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') account = Account.objects.get(username=username) if password == account.password: return redirect('view_basic_list') else: return render(request, 'myapp/login.html', … -

Efficiently extract large amounts of data from Django ORM
I have a Django setup with PostgreSQL DB. One of the tables contains large amounts of data (>1e9 rows) and I need to efficiently iterate over a large subset of it. Currently, when I try to select a large amount of data it starts buffering the result and my computer runs out of memory. If I use .iterator() on QuerySet, it just hangs. If I try to use raw SQL and fetchall() it also starts buffering. I believe Django uses psycopg2 for PostgreSQL which has cursor.itersize parameter, but when I try to use it with cursor in Django it doesn't do anything. I know that the problem is not on database end, since I can execute the query using psql (with -A --variable="FETCH_COUNT=10000") and it starts loading immediately without using any memory. Extra info: The table has >10 columns, but I only need 2 of them, so if it is possible to only fetch selected for faster loading it would be nice. -

On EC2 of the existing system, it operates in two containers, a web server (nginx) container and an AP server (django + gunicorn) container, and can be accessed normally from a browser. So, when I deployed it to the node (EC2) on AWS EKS in the same way, I could not access it from the browser and it was displayed as "502 Bad Gateway". The message "TIMEOUT (pid: 18294)" is displayed.

parse multiple values to user_passes_test in a function-based view
I have a function-based view #views.py def my_view(request,pk): post = Posts.get(pk) . . . return redirect("my-view") I want to make sure, that the user created the post, also is the one approaching the page. In the class-based update-view we can define the test_func class MyPosts(UserPassesTestMixin): def test_func(self): """ Check if the logged in user is the one created the link """ post= self.get_object() #Gets the current post if self.request.user == post.user: return True return False but I cannot figure out how to parse the post argument (or the post.user) to the user_passes_test function in the function-based view. According to the documentation the user_passes_test decorator has to take a function which takes a User argument as the first arguemnt and two optional arguments - and I need to parse both the User and the post-user i.e two user objects and not 1 e.g something like def my_test_func(User,post-user): if User==post-user: return True return False How do I accomplish this w/o using a Class-based view as described above? -
