Django select_for_update function in concurrent process
When I testing the function of update_or_create in multi threading condition, I found the result is not what I wanted,they created more than one record in MySQL.

How do I prevent post_save signals from triggering from a nested foreign key field?
Django model is sending two post_save signals and I can't figure out how to handle them. I want to trigger a single post_save signal on the save of an instance that has a foreign key field that is also being saved at the same time. This solution: How to save a model without sending a signal? seems close to home but my foreign key field must be an entirely new instance which means the update method won't work. Here's my model event = Event( start_date=template_fields['start_date'], end_date=template_fields['end_date'], event_title=f'Stock Count Reminder', description=f'Stock reminder count on auto scheduling', event_type=template_fields['event_type'] ) event.save() stock_tempalate.schedule_time = event stock_tempalate.created_by = info.context.user stock_tempalate.unique = True stock_tempalate.save() I want only stock_template.save() to trigger the post_save signal and not event.save() Here is my signal: @receiver(post_save, sender=StockCountTemplate) def start_job(sender, instance, **kwargs): if 'created' in kwargs: if not kwargs['created'] and instance.unique: start_schedule_templates() Putting a debugger in the signal's callback shows that I am receiving two signals. The first one doesn't have field values for the stock_templates while the second one does.

NoReverseMatch for user profile view
I need two different views for the user: a view user_details, it show the details of model User; a view user_profile, it show the details of model UserProfile models.py from django.contrib.auth.models import User from django.db import models from django.urls import reverse class UserProfile(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, related_name='profile_user', ) many_other_fields.... views.py from django.contrib.auth.models import User from django.shortcuts import get_object_or_404, HttpResponseRedirect, redirect, render from .models import UserProfile def user_details(request, username): user_details = get_object_or_404(User, username=username) template = 'usermanager/reading/user_details.html' context = { 'user': user_details, } return render(request, template, context) def user_profile(request, username): profile = get_object_or_404(UserProfile, username=profile_user.username) template = 'usermanager/reading/user_profile.html' context = { 'user_profile': profile, } return render(request, template, context) urls.py path('account-manager/<username>/', views.user_details, name="user_details"), path('account-manager/<username>/profile/', views.user_profile, name="user_profile"), template.html <a href="{% url 'user_details' username=user.username %}">User Details</a> <a href="{% url 'user_profile' username=userprofile.profile_user.username %}">User Profile</a> With this approach I see the error below: NoReverseMatch at /account-manager/max/ Reverse for 'user_profile' with keyword arguments '{'username': ''}' not found. 1 pattern(s) tried: ['account\-manager\/(?P[^/]+)\/profile\/$'] How I can solve this problem? Can you suggest me another approach? -
