Django regroup tag get fields values
I have a web page where I have 2 models for Products and Categories. I have this navbar where you can filter the Productos by categories, so in order to make it dynamic I passed the categories to the navbar and then applied a regroup since I'm getting the categories from the model Products since is the one the page is using to show the products. When I try to filter catching the value from the regroup and pass it to my view: class Categoria_Filter(ListView): model = Productos paginate_by = 10 template_name = 'mail/category-filter.html' def get_queryset(self): categoria = self.kwargs['slug'] print(categoria) if categoria == 'Todos': return Productos.objects.all() else: return Productos.objects.filter(categoria = categoria) I get the following result when printing: GroupedResult(grouper=<Categorias: Guantes de Box>, list=[<Productos: Guantes Básico ADX>]) which according to the docs is a namedtuple() I have tried the following: print(getattr(categoria, 'GroupedResult')) print(getattr(categoria, 'grouper')) print(getattr(categoria, 'Categorias')) They all give me: AttributeError: 'str' object has no attribute 'whatever field I have tried* Also, I print by index and for example: print(categoria[1]) gives me r Which I know is the r from GroupedResult and what I want to get from the namedtuple is Guantes de Box not: GroupedResult(grouper=<Categorias: **Guantes de Box**>, list=[<Productos: Guantes … -

custom error handler django when using django-hosts
I have a system that has deployed django-hosts, all is working fine. Until now I have been handling 404 and 500 errors for production by utilizing the neat trick of just placing files 500.html and 404.html in the root of the templates folder. This very nicely handles these errors in production (debug=False). However, now I want to get a little more creative with my error handling messaging and feedback to the user. I have other projects where I have created a custom view for the error handling. e.g. def custom_error_500(request, exception=None): print ('error 500 ') #For debugging to verify view is being processed. return render(request, "errors/500.html", status=500) and then set this parameter at the bottom of the urls.py (appname is 'main') handler500 = 'main.errorviews.custom_error_500' This all works very nicely in a project that does NOT use django-hosts. The advantage of creating the custom view is that the context is past to the RequestContext to the template, whereas by default not the case (see reference). Now, I know with django-hosts here is magic going on in the way urls.py are processed for each host. Could this be the reason why?. I tried placing the hander500 setting in all the possible urls.py … -

How does Python "mysqlclient/MySQLdb" know where to find "libmysqlclient?"
I'm getting a traceback which says that the "libmysqlclient" interface package cannot be found – and indeed it can't be found where Python is looking: /usr/lib. It looks from preceding trace entries that it's using @RPATH as the source of where to look. But ... how does Python actually know "where to look for MySQL?" -
django update database everyday
I made a wordlegolf site, www.wordlegolfing.com, where my friends and I play wordle and it tracks our scores daily. I keep track of all the users scores and have a scoreboard shown on the site. If someone forgets to do the wordle that day I currently manually adjust there scores to reflect that but I would like to make it so this is done automatically. I have the site running on heroku currently.

Django passing context in JsonResponse
I am developing a webpage with filters to filter the results on the page. A Ajax is called, which sends the filters to my Django back-end. The results are filtered and the data should be passed back to the front-end. So now I need to pass my results of the models with context to the front-end. This leads to some problems.

Django Many2Many constraint

Is it possible to expose a Django dev server running on a local machine to the public internet?
I'm new to Django and in trying to learn a little about running a server (firewall, permissions, ...) and deploying to production, I installed Ubuntu Server on an old laptop and connected it to my (wireless) router. I was able to set up port forwarding on the router, and to serve a static html page using nginx. I also bought a domain name and was able to change its DNS A record to point to my public IP address. This allowed me to go to mydomain.com and see my static html page. I tried to do something similar with the Django dev server but I could only access it on the local network. I set ALLOWED_HOSTS = ['*'] and ran the server on 0.0.0.0:8000 (after allowing incoming traffic on port 8000 using ufw on Ubuntu), and was able to access it from another computer on my local network by going to the local address 192.168.1.x. However, when I went to mydomain.com the page timed out. Is it possible in principle to achieve this? I know it's not a good idea to run a site this way but I only want to do it to learn and will allow access only … -

The first thing I want to apply this to is a user status validation that is included with every view today: views.py def myview(request): user_profile = UserAccount.objects.get(user=request.user) if user_profile.type != "internal" and user_profile.type != "flex": if user_profile.duration < datetime.date.today(): return redirect('expired') If I understand it correctly, I can apply DRY here by building a custom decorator, or by building class-based views for my app - for example by extending a DetailView and building a base class for all my views around this. Are there any trade-offs to be aware of when choosing approach? I imagine class based views may be more scaleable in terms of applying DRY to other parts of the app, but the learning curve also seems a bit more steep in order to get to a point where it's actually working. -
Get the intersection of a django queryset with a __in
So I have an array and a queryset. some_array = [...] queryset = queryset.filter(some_field__in=some_array) Actually it returns every object that the "some_field" is in the array. What I want is only the objects that have all the fields from the array. Thx -
How I manage barbershop bookings based on length of service in Django
I'm supposed to manage barber salon bookings during the day based on length of service. For example: cut: 30 minutes cut + shampoo: 40 minutes There are multiple barbers in the salon. for now I have developed the barbershop and services models but I don't know how to implement the appointments and have them displayed for available time slots. class Barber(models.Model): name = models.CharField(max_length=255) surname = models.CharField(max_length=255) role = models.CharField(max_length=255) def __str__(self): return self.name + ' ' + self.surname class Service(models.Model): name = models.CharField(max_length=255) duration = models.PositiveIntegerField() price = models.FloatField() info = models.TextField(blank=True, null=True) def __str__(self): return self.name The appointment model I thought of implementing it in this way: class Appointment(models.Model): barber = models.ForeignKey(Barber, on_delete=models.CASCADE, related_name='appointments') service = models.ForeignKey(Service, on_delete=models.CASCADE, related_name='appointments') start_date = models.DateTimeField() name_client = models.CharField(max_length=255) client_email = models.EmailField() number_phone_client = models.CharField(max_length=10) def end_date(self): return self.start_date + timedelta(minutes=self.service.duration) But now I don't know how to manage the various slots available in a possible view based on the service and the barber chosen. -
AWS_QUERYSTRING_AUTH = False not working with cached AWS S3 images of public S3 bucket
I have a public AWS S3 bucket where I store mostly images for our site. I use boto3 to access and update images in the bucket. Usually, I wrap my calls to images in my templates in sorl thumbnail tags like so: {% thumbnail post.get_thumbnail_image.url '350x230' crop='center' as im %} <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}" alt="{{ post.title }}"> {% endthumbnail %} which results in the returned images looking like: https://mybucket.s3.amazonaws.com/cache/e4/8f/e48f5547cec7e4a869696527fac12a8f.jpg I now want to use Memcached to cache entire views on the website. I wouldn't think that would be a problem for a public bucket, because I don't expect the images requested to require a signature. Which is true once I set AWS_QUERYSTRING_AUTH = False in my settings.py - the images stop carrying signatures. The problem is though that even for a public bucket with AWS_QUERYSTRING_AUTH = False, the thumbnail files I get back throw an Access Denied error when the signatures are removed. Is this a matter of flushing some S3 cache somewhere? How can I make these cache thumbnail files respect my AWS_QUERYSTRING_AUTH = False? -
ModuleNotFoundError: No module named 'config.wsgi'
I'm trying to run a .py file and in the file I have this import from config.wsgi import * import os from django.template.loader import get_template from weasyprint import HTML, CSS from config import settings The whole project works, if I set runserver, the project starts without any problem, but this file does not work. The structure of the project is as follows NombreDelProyecto --app ---config ----__init__.py ----asgi.py ----settings.py ----wsgy.py ----db.py ---core ----general ----login ----user ----archivodetest.py the case as I say the project works, but in the views of the applications that I have been doing to put imports I get in red underlined but as I say it works for example: from core.general.forms import ActividadForm That comes out in red, if I put in front of the core, app.core as follows from app.core.general.forms import ActividadForm it does not show red but the project does not work and I get the following error from app.core.general.forms import ActividadForm ModuleNotFoundError: No module named 'app' I understand that it is the routes or something I did wrong from the beginning, please could someone help me. Thank you very much. I tried adding the route, changing the app's route in settings, but to no avail.
