Django SuspiciousFileOpretation at /admin/
I know many people asked this question. I have two laptops, one uses python 3.7 another one uses python 3.6. The code is the same, the second laptop raises this error. here is my file in admin: admin.site.register(File) in models class File(models.Model): files = models.FileField() settings BASE_DIR = os.path.dirname(os.path.abspath(__file__)) MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') any idea why I get this error when using python 3.6? -
Celery what happen to running tasks when using app.control.purge()?
Currently i have a celery batch running with django like so: Celery.py: from __future__ import absolute_import, unicode_literals import os import celery from celery import Celery from celery.schedules import crontab import django load_dotenv(os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env')) os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'base.settings') django.setup() app = Celery('base') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() @app.on_after_configure.connect def setup_periodic_tasks(sender, **kwargs): app.control.purge() sender.add_periodic_task(30.0, check_loop.s()) recursion_function.delay() print("setup_periodic_tasks") My aim is whenever the celery file get edited then it would restart all the task -remove queued task that not yet execute(i'm doing this because recursion_function will run itself again if it finished it's job of checking each record of a table in my database so i'm not worry about it stopping mid way). The check_loop function will call to an api that has paging to return a list of objects and i will compare it to by record in a table , if match then create a new custom record of another model My question is when i purge all messages, will the current running task get stop midway or it gonna keep running ? because if the check_loop function stop midway looping through the api list then it will run the loop again and i will create new duplicate record which i don't want -

Django-simple-captcha Play Captcha Audio In Browser Not In Downloaded .wav File
By default, django-simple-captcha uses the flite linux command line program to convert the captcha text into a downloadable .wav file when a user clicks on the captcha image. Instead of downloading .wav files, a better user experience would be to play the audio directly in the browser by clicking a play button. How would one go about changing the default behavior of django-simple-captcha to do this? Is there a way to get it to universally work across many different forms such as template forms, allauth forms, etc? -
Django Models Custom user admin
I have a business model that will have a primary admin and multiple other admins/editors. Initially I was thinking about a manytomany field but I'm afraid this will not resolve the complexity of who's the primary admin or their level of administrative permissions such as an admin or just an editor. Any suggestions on resolving this schema design? class Business(models.Model): username = models.CharField() name = models.CharField(max_length=250) address = models.CharField(max_length=250) location = models.PointField(srid=4326) -

How do I get the string value of the tuple in Django
This sounds like a noob question, I just want to ask how do I get the string value of this tuple. USER_TYPE_CHOICES = ( (1, 'PQA'), (2, 'Tester'), (3, 'Test Lead'), (4, 'Test manager'), (5, 'Senior Test Manager'), (6, 'admin'), ) user_type = models.PositiveSmallIntegerField(choices=USER_TYPE_CHOICES) When I call the value as: <h1> {{ user.user_type }} </h1> It shows up as the int value and not the string. It sounds very simple but I can't seem to find it on the python documentation. -

Why I can't call multiple stored procedures consecutively with Django and Postgres
I have a class in python, the class has the following methods self.__evaluateAmenityBuffers() self.__evaluateTransitBuffers() self.__evaluateRoadsBuffers() self.__evaluateRiskBuffers() self.__EvaluateJobsBuffer() in each method I call a stored procedure with Django, the code is similar to the next one cur = connection.cursor() cur.callproc("urbper_buffer_amenities", [self.scenario]) the issue I am facing with is that only the first method writes its changes in the data base, If I comment the first method, the second one works but the next methods are executed but their chages are not stored in the database. ¿could you help to find out what am I doing wrong? -

Importing existing blog posts into django-cms-blog
I am integrating an existing web-application into django-cms. So far, my application had a blog application not from django-cms, which currently contains several thousand blog-posts. Im trying to import them into the django-cms-blog application. Until now, I have imported all fields successfully, such as title, category, ... into the django-cms-blogpost model except for the Placeholder fields, where the content of blogs is saved in. I know that I can access it from the frontend, but this way I would have to copy all the content of the previous blog-posts manually into the current. So my question is: Is it possible to add content to placeholders from the backend? -

Django query record with largest version in group
I have a very simple Django model which represents a versioned Product: class Product(models.Model): name = models.CharField(max_length=50) version = models.PositiveSmallIntegerField(null=True) class Meta: unique_together = ("name", "version") def __str__(self): return f"{self.name} ({f'v{self.version}' if self.version else 'DRAFT'})" I can create some products in the database using the following script: p1_v1, _ = Product.objects.get_or_create(name="One", version=1) p1_v2, _ = Product.objects.get_or_create(name="One", version=2) p1_v3, _ = Product.objects.get_or_create(name="One", version=3) p1_draft, _ = Product.objects.get_or_create(name="One", version=None) p2_v1, _ = Product.objects.get_or_create(name="Two", version=1) p2_v2, _ = Product.objects.get_or_create(name="Two", version=2) p3_draft, _ = Product.objects.get_or_create(name="Three", version=None) I need to perform a query that returns the latest version of each Product (excluding Products with no version). That is, the target result is the following Queryset: <QuerySet [<Product: One (v3)>, <Product: Two (v2)>]> The following works with PostgreSQL but fails with SQLite: Product.objects.exclude(version__isnull=True).order_by("name", "-version").distinct("name") # <QuerySet [<Product: One (v3)>, <Product: Two (v2)>]> I'm able to get the max version per name here but I'm not sure how to get the actual objects from the db: Product.objects.values("name").annotate(max_code_version=Max("version")) # <QuerySet [{'name': 'One', 'max_code_version': 3}, {'name': 'Two', 'max_code_version': 2}]> How can I execute this query? -
