Unable to access / var / tmp in Subprocess via Django
I created a script that outputs the execution result of a shell script to a Web screen using Django and subprocess of python. Specifically, the following two scripts were created. test.py #!/usr/bin/python import sys,os import subprocess import syslog command_list = ['/bin/sh', '/var/tmp/test.sh'] proc = subprocess.Popen(args=command_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=os.path.dirname(command_list[0]), shell=False) result = proc.communicate(input=None) print str( result ) test.sh #!/bin/bash echo "begin" cat /var/tmp/data.txt data.txt data1 data2 Unit tests were performed on the two scripts, and they were confirmed to work properly. However, when I used test.py via Django, test.sh's "cat" command and data.txt existed, “Cat: /var/tmp/data.txt: No such file or directory” is displayed. What is the cause? version python 2.7.13 Django 1.11.20 -
Why do I get 'detail: not found' for primary key formatted as '12-345.78'?
When I try to display detail info calling e.g. /api/products/12-345.67/, I get detail: Not found. as a response. As you can see, product IDs are formatted as 12-345.67. My first suspect was the RegEx validator (listed below), but it works the same way with or without it. Model, serializers, viewsets and URLs are defined this way: # models.py: class Product(models.Model): product_id = models.CharField(max_length=9, primary_key=True) name = models.CharField(max_length=40) is_active = models.BooleanField(default=True) def __str__(self): return self.product_id # serializers.py: class ProductSerializer(serializers.ModelSerializer): product_id = serializers.RegexField(regex='^\d{2}-\d{3}\.\d{2}$', max_length=9, min_length=9, allow_blank=False) name = serializers.CharField(min_length=6, max_length=50, allow_blank=False) class Meta: model = Product fields = '__all__' class ProductViewSet(viewsets.ModelViewSet): queryset = Product.objects.all() serializer_class = ProductSerializer lookup_field = 'product_id' # urls.py: router = routers.DefaultRouter() router.register(r'products', ProductViewSet, basename='products') (...) urlpatterns = [ path('api/', include(router.urls)), (...) -

Return the progress to the template each value change in Django
I want to show the progress of the task going in the back-end in order let the user know that the work is still in progress. I have ajax call to a function to get the final value. In back end it will take lot of time to complete the job, but each time i have the progress of the job in one variable i want to show the values of this variable in the front end. For example my ajax function is def ajax_call(request): j = 0 for i in range(1,10000): j += i res = {'data': j} return JsonResponse(res, safe=False) As we know it will return the final value of j. But i want to show the value of j in the front end in each change. Is there any simple way to do this using celery or something -

How can I use '{{' , '}}' letter for plain text on template?
The problem was shown when I wanted to explain syntaxes of Django templates on my html document. However, {{ or {% letters are recognized and by the template engine, so I couldn't use them for just plain string. How can I make Django template engine to bypass that letters? I have already tried to use some letters, like backslash \ or Django template's comment function {# #}. First, backslash was not worth at all. Second, comment function makes bypassing everything inside the function. It is an example of my situation: <p>A variable outputs a value from the context, which is a dict-like object mapping keys to values. Variables are surrounded by {{ and }} like this:</p> <p>My first name is {{ first_name }}. My last name is {{ last_name }}.</p> I expected the output have to be like: A variable outputs a value from the context, which is a dict-like object mapping keys to values. Variables are surrounded by {{ and }} like this: My first name is {{ first_name }}. My last name is {{ last_name }}. But actually, it was like: A variable outputs a value from the context, which is a dict-like object mapping keys to values. … -

Celery tasks don't send email to admins on logger critical messages
My celery tasks don't send an email to application admins each time I call logger.critical. I'm building a Django application The current configuration of my project, allows the admins of the application to receive an email each time a logger.critical message is created. This was pretty straight forward to set up. For some reason, which I'm not figuring out, the code that runs inside a celery task, does not have the same behavior. Does celery actually event allow this to be done? Am I missing some configuration? Does anyone got this problem and was able to solve it? Using: Django 1.11 Celery 4.3 Thanks for any help. -

Django: ManyToManyField saves choices that I don't put checks

Why am I getting a circular import error with django?
This question seems to be asked before but none of the answers I came across solve my issue. I'm getting the following error when I try running the server with python manage.py runserver: django.core.exceptions.ImproperlyConfigured: The included URLconf 'tutorial.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. The error goes away if I change models.py so that my Item class does not extend models.Model. These are the relevant files: models.py from django.db import models from django.contrib.auth.models import User class Item(models.Model): name = models.CharField(max_length=255) owner = models.ForeignKey(User, on_delete=models.CASCADE) price = models.DecimalField(decimal_places=2) def __str__(self): return self.name serializers.py from rest_framework import serializers from django.contrib.auth.models import User, Group from .models import Item class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = ('url', 'username', 'email', 'groups') class GroupSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Group fields = ('url', 'name') class ItemSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Item fields = ('url', 'name', 'owner', 'price') urls.py from django.urls import include, path from rest_framework import routers from tutorial.quickstart import views router = routers.DefaultRouter() router.register('users', views.UserViewSet) router.register('groups', views.GroupViewSet) router.register('items', views.ItemViewSet) urlpatterns = [ path('', include(router.urls)), path('api-auth/', include('rest_framework.urls', namespace='rest_framework')) ] -
How to Prevent SIGINT in one Heroku process from causing others to shut down?
I have a Django project that consists of four separate Heroku processes. The Procfile is included here: jobs: python manage.py sync_hacker_news web: gunicorn project.wsgi --log-file - rqworker_default: python manage.py run_worker rqworker_high: python manage.py run_worker --high web starts a web server, and rq_worker_* start high and low-priority Redis queue workers for async tasks. jobs is the problematic task. It's responsible for calling the following management command: import logging from apscheduler.schedulers.background import BackgroundScheduler from django.core.management.base import BaseCommand from django_apscheduler.jobstores import (DjangoJobStore, register_events, register_job) from subscriptions import autocomplete from subscriptions.notifications import schedule scheduler = BackgroundScheduler() scheduler.add_jobstore(DjangoJobStore(), "default") logger = logging.getLogger(__name__) @register_job(scheduler, "interval", minutes=5) def async_hacker_news_sync(): logger.info("Sync new data from Hacker News API.") autocomplete.get_accounts.delay() schedule.delay() class Command(BaseCommand): help = "Sync usernames and notifications with Hacker News." def handle(self, *args, **kwargs): register_events(scheduler) scheduler.start() print("Scheduler started!") My intent is for this command to register a task with django_apschedulerto query the HackerNews API every 5 minutes. The problem is that once this command runs, it terminates (which is expected) and results in SIGINT getting called. This causes web and rq_worker_* tasks to shut down as well.

It should have the pythonpath and setting for the second site. /home/www# ls -l drwxrwxr-x 6 www-data www-data 4096 Oct 21 00:55 nerds.tech drwxrwx--- 4 www-data www-data 4096 Oct 21 00:54 secret drwxr-xr-x 2 www-data www-data 4096 Oct 21 01:01 uwsgi-ini each with their own .ini file /home/www# ls -l uwsgi-ini/ total 8 -rwxrwx--- 1 www-data www-data 671 Oct 21 00:57 suwsgi.ini -rwxr-xr-x 1 www-data www-data 947 Oct 21 00:57 uwsgi.ini . /home/www# cat /home/www/uwsgi-ini/uwsgi.ini [uwsgi] master = true vacuum = true die-on-term = true uid = www-data gid = www-data socket = /tmp/uwsgi.sock chdir = /home/www/nerds.tech/nerds pidfile=/tmp/uwsgi-master.pid virtualenv = /home/www/nerds.tech/venv pythonpath = /home/www/nerds.tech/nerds module = nerds.wsgi:application . /home/www# cat /home/www/uwsgi-ini/suwsgi.ini [uwsgi] master = true die-on-term = true uid = www-data gid = www-data vacuum = true chmod-socket = 660 socket = /tmp/suwsgi.sock chdir = /home/www/secret/exchange pidfile=/tmp/uwsgi-master.pid virtualenv = /home/www/secret/venv pythonpath = /home/www/secret/exchange … -
