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. -

Wagtail: How can I access 'request' in a Page class in models.py

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? -

Nginx routing Django Web App links to wrong path
I have a django app where the hompage routes correctly, but when I try to click on any of the links I get a 404 error. I looked at the logs and see: *1 open() "/usr/share/nginx/html/pricing" failed (2: No such file or directory) which tells me that nginx is not looking at my project folder but instead what seems to be a default setting. I am using centos, so I had to manually setup sites-available and sites-enabled, which I have used to get the homepage working. As such there is no default conf to disable. I am unsure how to get nginx to route to my path instead of the default. My nginx.conf file looks like this: user so_dev; worker_processes auto; error_log /var/log/nginx/error.log; pid /run/nginx.pid; include /usr/share/nginx/modules/*.conf; events { worker_connections 1024; } http { log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; #added by me } -
