Django axes resets cool off the moment another failed login occurs
Currently, django axes will reset the cool off timer to the latest time a failed login attempt happens eg. after 3 login failed login attempts axes will lock out the user account for 15 minutes until 1015am(unlock at 1030am). If i attempt a 4th time at 1020am it will extend the lockout to 1035am. Is there anyway to modify axes so that it will not reset the cool off time on login attempt failure? -
Django redirect using an object id?
The main issue I'm having is using the {% url 'Name' %} feature In my html file "productview.html" {% extends "droneApp/base.html" %} {% block content %} <div> {{ objects.name }}<br> </div> <button onclick="window.location.href='{% url 'Checkout/{{objects.id}}' %}'"> {% endblock %} The productview.html page's url is http://127.0.0.1:8000/Store/Product/1 Where 1 is the product id I'm trying to redirect to the checkout page using a button. But I don't understand how to redirect to my html Checkout.html In a previous html file we used href='Checkout/{{item.id}}' but if we use that in this file it just causes the urls to stack into http://127.0.0.1:8000/Store/Product/Checkout/1 instead of http://127.0.0.1:8000/Store/Checkout/1 How do I properly redirect to the right html file? urls.py file from django.urls import path from .import views urlpatterns = [ path('', views.Store, name= "Store"), path('Checkout/<id>', views.createlocation, name="Checkout"), path('Product/<id>', views.product_details, name="Product") ] Which is imported from another urls.py file path('Store/', include('storeApp.urls')), -
How do I configure Django's auth user model to have a UUID (Postgres DB)
I'm using Python 3.9 and Django 3.2. Here is my folder structure + cbapp - settings.py + models - __init__.py - custom_user.py - manage.py Here's what my customer_user.py file looks like $ cat models/custom_user.py import uuid from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): pass uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) Additionally, I have configured this in my settings.py file AUTH_USER_MODEL = 'models.CustomUser' However, when I run "python manage.py makemigrations", I get this error django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'models.CustomUser' that has not been installed I have no idea what this means.

Django Models, Custom Model Managers and Foreign Key -- don't play well together
I will simplify the problem as much as I can.

Django DB2 with Multiple Schemas
I would like to know whether it is possible for the Python(3.8.10)-Django(3.2) to connect to the DB2 with multiple schemas. Currently, I am using the settings similar to the example in the GitHub DATABASES = { 'default': { 'ENGINE' : 'ibm_db_django', 'NAME' : 'mydb', 'USER' : 'db2inst1', 'PASSWORD' : 'ibmdb2', 'HOST' : 'localhost', 'PORT' : '50000', 'PCONNECT' : True, #Optional property, default is false }, 'MYSCHEMA': { 'ENGINE' : 'ibm_db_django', 'NAME' : 'mydb', 'USER' : 'db2inst1', 'PASSWORD' : 'ibmdb2', 'HOST' : 'localhost', 'PORT' : '50000', ‘SCHEMA’ : ‘MYSCEHMA’, # no error for adding the ‘SCHEMA’ parameter (or not) until running 'PCONNECT' : True, #Optional property, default is false } However, it is using db2inst1 as the default schema. Is it possible to use other schema? For instance, I am using MYSCHEMA for the application. For the above settings, I am not sure what I could fill the schema name in the DATABASE variables. I have added in corresponding coding: SomeModel.objects.using(‘MYSCHEMA’).all() #The default is to use the “default” database connection. Once it is running in the Django, it will show db2inst1.tabname is an undefined name. (Table willing to use: MYSCHEMA.tabname) -
Easy 'for loop' for datetime field not working in Django(google chart)
I'm trying to use google chart in my Django project, the google chart required a format like ['label1', 'label2', 'label3', new Date(Y, m, d), new Date(Y, m, d), null, 100, null], it's like a list, so I'm trying to keep things simple first, I only replaced the date and leave other fields as default.

Avoid Celery retries for unregistered task
We have a Django app with celery to handle an asynchronous tasks. We use AWS SQS as the task broker. We ended up with a bad task to be processed (removed the task implementation without removing the celery-beat entry). This resulted in errors: Received unregistered task of type KeyError('some_deleted_task'). The message has been ignored and discarded. Once we cleaned up the celery-beat entries, we continued getting errors ~2min (visibility timeout on SQS was set to 2 minutes). Behaviour seemed to be: Task added to queue, in SQS as 'Available' Worker picks up the task, moves the SQS message to 'in flight' Worker fails immediately due to missing implementation. two minutes later, SQS moves the message from 'in flight', back to 'available' Goto 2 To clear the errors, we purged the SQS queue, but this could have resulted in losing other tasks. I'd like to configure celery so it won't keep trying these missing tasks indefinitely. -
Why is plotly failing to load in django project?

pytest parametrize is deleting my fixturedata after first parametrize value

In my test i am deleting some model instances through a post request(which in the view is wrapped with a transaction.atomic request). This is why i need transaction=True, because the deleted objects need to be there again when the second run of parametrize runs. Now, my problem is that if i use transaction=True, on the second run it will revisit my fixtures but now suddenly my database is empty, the Groups.objects.all() method doesn't return anything at all. If i switch back to transaction=False, it works but this way i have a problem because my post request deleted stuff that i need for the next parametrize run. What am i doing wrong? I don't get it :( ughhh -
