Django admin page login causing IIS to crash, need to restart iis everytime
My site is working fine. I can access all the pages. But when I am accessing admin page, it loads, prompts for username and password. After entering username and password when clicked login, it takes sometimes and after that I get below error: This page isn’t working mytestapp.company.com didn’t send any data. ERR_EMPTY_RESPONSE After refreshing the page, I get below error: Service Unavailable HTTP Error 503. The service is unavailable. After this no page loads. After restarting IIS using cmd (iisreset /noforce) again when I try to refresh the homepage, I see I am logged in which means admin page logged me in but after that response did not come and it something went wrong on the server side which caused server to crash. I am not sure how to proceed with this. Earlier my admin site use to work fine. No recent changes in code. The only change I did is I synced the DB from another DB which has more data. I am using virtual env which has python version is 2.7.3, Django version 1.3 in it IIS version 7.5 on WindowsServer 2008R2 (Python IsAPIe handler) Please help me on this.

Creating a Path Based on SlugFields in Django
I have a Django project based around creating tournaments and nesting specific objects within them. For instance, every tournament has multiple committees. When someone creates a tournament, I allow them to create a link with a SlugField. My code (so far) is as follows: models.py from django.db import models from django.utils.text import slugify class Tournament(models.Model): name = models.CharField(max_length=50) slug = models.SlugField(max_length=50, unique=True) def _get_unique_slug(self): ''' In this method a unique slug is created ''' slug = slugify(self.name) unique_slug = slug num = 1 while Tournament.objects.filter(slug=unique_slug).exists(): unique_slug = '{}-{}'.format(slug, num) num += 1 return unique_slug def save(self, *args, **kwargs): if not self.slug: self.slug = self._get_unique_slug() super().save(*args, **kwargs) class Committee(models.Model): name = models.CharField(max_length=100) belongsTo = models.ForeignKey(Tournament, blank=True, null=True) slug = models.SlugField(max_length=50, unique=True) def _get_unique_slug(self): ''' In this method a unique slug is created ''' slug = slugify(self.name) unique_slug = slug num = 1 while Committee.objects.filter(slug=unique_slug).exists(): unique_slug = '{}-{}'.format(slug, num) num += 1 return unique_slug def save(self, *args, **kwargs): if not self.slug: self.slug = self._get_unique_slug() super().save(*args, **kwargs) views.py from django.shortcuts import render, get_object_or_404 from .models import Tournament, Committee def tournament_detail_view(request, slug): tournament = get_object_or_404(Tournament, slug=slug) return render(request, 'tournament/detail.html', {'tournament': tournament}) def committee_detail_view(request, slug): committee = get_object_or_404(Committee, slug=slug) return render(request, 'committee/detail.html', {'committee': committee}) urls.py … -

Downloading files from the server in a Django application
I want an app in my Django project to generate a list of files stored at a known location on the server, present them as a list to the user, with links for them to download. I am comfortable with Python, and am also familiar with Jinja templating syntax, rendering a template etc.. The bit I am struggling with is the concept of MEDIA files in Django. Everything seems concerned with handling uploaded files. I simply want to access files at a known location on the server (one which is however, outside of my Django project). Is this possible? Is this workflow sensible or am I fundamentally misunderstanding a core concept? Is there some kind of approach (like collectstatic) that should be used, to pull all media files into the project for deployment and then allow them to be served? I am just getting in to Django and have made some basic sites and applications which work well. The fundamentals seem to make sense to me. This is my first attempt a doing some file downloading, and this is where I have run into issues. Note: I have a feeling that perhaps getting files from outside the Django project might … -

How display post "on moderation" for admin at site page "Post list" at Django 2.1?
I want to display a new post, which exist "on moderation", for the administrator (staff), at site page "Post list" (template "post_list.html"), for example "scrin1" (Post 1 - published; Post 2 - "on moderation"). Regular user can see "Post list" only with published posts, see "scrin2".

AttributeError when setting custom DEFAULT_METADATA_CLASS
I have written a custom metadata class for OPTION requests. This class is located in myproject.api.metadata.py and is called PermissionsMetadata.

I just need the metadata class to apply to all views by default without having to set the metadata_class attribute on every view. I don't mind moving the class elsewhere. By the way, setting the default metadata class to rest_framework.metadata.SimpleMetadata doesn't result in this exception. Help greatly appreciated. -

I have a question about Celery with 2 Django applications on the same server (server is a FREEBSD server). Let suppose that we have app1 and app2. App1 gets a celery.py file like this : import os from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'main.settings.base') app = Celery('main-app1') app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all registered Django app configs. app.autodiscover_tasks() The second one has the same file but I changed app = Celery('main-app1') to app = Celery('main-app2') On my server, I have a celeryd file configured for app1 like this : # Names of nodes to start # most people will only start one node: CELERYD_NODES="worker" # but you can also start multiple and configure settings # for each in CELERYD_OPTS #CELERYD_NODES="worker1 worker2 worker3" # alternatively, you can specify the number of nodes to start: #CELERYD_NODES=10 # Absolute or relative path to the 'celery' command: #CELERY_BIN="/usr/local/bin/celery" #CELERY_BIN="/usr/local/www/app1/venv/bin/celery" CELERY_BIN="/usr/local/bin/celery" # App instance to use # comment out this line if you don't use an app CELERY_APP="main-app1" # Where to chdir at start. CELERYD_CHDIR="/usr/local/www/app1/src/web/" # Extra command-line arguments to the worker CELERYD_OPTS="--time-limit=300 --concurrency=8" # Configure node-specific settings by appending node name to arguments: #CELERYD_OPTS="--time-limit=300 -c 8 -c:worker2 4 -c:worker3 2 -Ofair:worker1" # Set …
