How to use tuple in Django expression?
How can I use tuple in Django expressions? I want to be able to annotate QuerySet with some tuple, so that I can make ordering according to that annotation or filter things greater or smaller according to that annotation. I can order by multiple fields (without the need for annotation), but I can't easily filter something without implementing complex logic myself. It would be also nice if this could be used with existing code that uses "greater than" or "less than" filtering. (I could chain bunch of ORs handling things element by element, but I would be surprised if I'm the only one who needs something like this, I don't want to reinvent wheel.) I want standard SQL ordering, where left-most element has highest priority (for example SELECT (1,2) < (3,0) AS TEST returns TRUE). -
Browser blocks cross domain iframe cookies
I have a forum-like component which I use in an iframe on other websites. This component uses django-allauth for authentication with Facebook and Google. Everything worked fine but now the authentication stopped working some time ago. When I look at the cookies in my browser, the cookies from Facebook/Google which are set by the iframe, are not loaded. Although, the cookies from the component itself are set. The authentication still works when I load the iframe on a website which is on another subdomain of the component itself. Tool on another subdomain (working): https://shop-sandbox.adbuddy.be/discussie/ Tool on a totally different domain (not working): https://mama-calinka.webbuddy.be/discussie/ I guess this problem had something to do with CORS-headers but nothing I've tried helped. Can someone help me with this problem please? -

Django + AWS s3 can upload files but not access them
Following this tutorial I set up our system to use Amazons S3 file storage using boto3 and Django-storages. I ran the collectstatic command and it worked just fine, the files show up in the AWS Management Console. But when running the server locally (runserver) all static files are missing. Looking at the console there are the error messages GET https://BUCKET.s3.eu-central-1.amazonaws.com/static/admin/css/nav_sidebar.css net::ERR_ABORTED 403 (Forbidden) for each of the files. The url looks right to me, the upload worked fine, but apparently the access doesn't work. Does this have something to do with my config in AWS? Or is this a django settings issue? -
Django - Certain Py Module doesn't work in IIS
This is my first time putting a question here. Some background, I started coding on Django this year and Python more than a year but less than 2 years so I don't much. This problem is a concern to my what I developing in at work. And my team working on it is novice or no experience on coding Python or Django or both. The Problem We have a web app based on Django 3.0.2 and use MSSQL for the db. Our company policy is to use Windows server and IIS as the prod and test server. We done a lot of work on it and all work well except for some python library and Django module that don't work, mainly Xlwings and Django-post-office. For XLwings, it doesn't run the code and Excel(we have valid license and latest Excel programme on the server). code below; filepath = BASE_DIR + '\\media\\Template.xlsm' temp_path = BASE_DIR + '\\media\\' + '{}.{}'.format(uuid4().hex, 'xlsm') shutil.copyfile(filepath, temp_path) pythoncom.CoInitialize() app1 = xw.App(visible=True) wt = xw.Book(temp_path) sht = wt.sheets['Cover'] sht.range('E5').value = request.POST.get('year') sht.range('E6').value = request.POST.get('company') sht.range('E7').value = companydata.employer_no sht.range('E8').value = email wt.save(temp_path) app1.quit() As for Django-post-office, we have module using it working but other modules using it doesn't work. … -

Where are my environment variables in Elastic Beanstalk for AL2?
I'm using elastic beanstalk to deploy a Django app. I'd like to SSH on the EC2 instance to execute some shell commands but the environment variables don't seem to be there. I specified them via the AWS GUI (configuration -> environment properties) and they seem to work during the boot up of my app. I tried activating and deactivating the virtual env via: source /var/app/venv/*/bin/activate Is there some environment (or script I can run) to access an environment with all the properties set? Otherwise, I'm hardly able to run any command like python3 manage.py ... since there is no settings module configured (I know how to specify it manually but my app needs around 7 variables to work). -

How can I get the full URL from my request argument? [duplicate]
I have a method that resolves a get request that looks like this: import json import json_api_doc import requests from django.conf import settings from django.core.cache import cache from django.utils import timezone from rest_framework.response import Response from rest_framework.views import APIView class MyClassAPIView(APIView): def get(self, request): foo = request.query_params.get('foo', '') # url = request.url <-- this does not work, but is what I'm trying to accomplish ... return {...} As you can see, I am able to get the query_params, but I would also like to get the full URL that is coming in.

I am successfully getting the query_param -- how can I get the full URL? -

Django Models (dynamic?)
I am just starting Django Website; I have deciced to go with a model (with SQLite DB), which have the following properties: class Flow(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE, verbose_name="Owner", default="ADMIN") source = models.CharField(default='HTTP', choices=SOURCE_CHOICES, editable=True, max_length=12) name = models.CharField(max_length=50, default=" ") date = models.DateTimeField(verbose_name="Creation date") I want to add others fields to this model depending on the source field value. For example if the source field : 'File' is selected. I will create additionnal field (like file name, file directory ...) If 'Http' is selected, I will create a field URL. Thus depending on the source field, I will have differents field and type. I have read this kind of model is difficult to reprensent in Django; I am open minded to other kind of solution. My idea was to created as many model as the possible source value. -

Django i18n translation after changing default language
I have two languages on the website - en and ru. When the project started, the default language was en. So, in the template I type something like {% trans 'Hello' %} and make translations only for ru in the locale folder. But now I have changed the default language to ru. And now the website was in ru even if the language is en because I haven't translated anything for en (it's already in en however). How to fix it? how to make it so that in the absence of translation i18n doesn't translate anything and shows just the text as it is? Thanks. -

Django 3: Passing slug in URLs to views?
I'm trying out Django for a webshop, I'm following the instructions of a book(Django 3 by example), but there seem to be something missing. I have tested if return to home in def product_list seen in views.py, so I believe the problem is in the "if category_slug:" condition or it is not receiving the slug.
