Populating models inner classes from the same table
I had a database composed by: Table1: columns: a1, b1, c1 Table2: columns: a2, b2 And for the models I had: class Table1(models.Model): a1 = models.IntegerField(id) b1 = models.CharField() c1 = models.ForeignKey(Table2) class Table2(models.Model): a2 = models.IntegerField(id) b2 = models.CharField() So to access instances of Table2 all my system worked around this: table1.table2.b2 Bu that database has been reestructured to: Table1: columns: a1, b1, a2, b2 Hence my model became: class Table1(models.Model): a1 = models.IntegerField(id) b1 = models.CharField() table2_a2 = models.IntegerField(id) table2_b2 = models.CharField() So now in order to access the old value b2 I need to: table1.table2_b2 Is it possible to do something like to following model? class Table1(models.Model): class Table2(models.Model): a2 = models.IntegerField(id) b2 = models.CharField() a1 = models.IntegerField(id) b1 = models.CharField() table2 = Table2() table2.a2 = models.IntegerField(id) table2.b2 = models.CharField() -

Load result from requests.get into django template (tableau)?
I've got a super tiny (one view) django application that loads a view from a tableau server. I've got it working with the trust app method of connection and if I just put the URL into a browser it loads up okay without issue. When I try to render that same page inside of a django template however - django tries to load all the resources as if they existed locally (which doesn't work). The view looks like this: def index(request): url = os.environ.get("tableau_HOST") username = request.user.username ticket = get_tableau_ticket(url, username) if ticket: data = requests.get(url+ticket+'/views/SIPPlan/DashboardView', data={'username': username}) print(data.text) else: # Handle the error - not implemented yet r = ticket return render( request, "tableau/index.html", { "tableau_data": data.text, }, ) Inside my template it looks like this: {% extends "myapp/base_template.html" %} {% load static %} {% block content %} {% autoescape off %} {{ tableau_data }} {% endautoescape %} {% endblock %} When I load the view - I see it trying to load the resources from my local machine (which it shouldn't, they exist on the tableau server).

How to save the number of registered users in mongodb?
I have a problem and I am looking for a solution. I want to save the number of users registered in mongodb. For example, in django, the admin page has the number of registered users, and all other data is saved there.

S3 versioning with django-storages
I use django-storages in my app, and I want to use S3 versioning just out of the box. I mean, I want to store and retrieve different versions of the same file without implementing any additional mechanism. By reading the docs, I understand that: Retrieving an object is as easy as adding a version=XX parameter to the GET request. Uploading an object is handled by S3 itself. You just need to configure versioning in your bucket But, going to the code. If I have this: from django.db import models from django_s3_storage.storage import S3Storage storage = S3Storage(aws_s3_bucket_name='test_bucket') class Document(models.Model): name = models.CharField(max_length=255) s3_file = models.FileField(storage=storage) How can I get one specific version of a Document? Something like: doc = Document.objects.get(pk=XX) doc.s3_file.read(version=XXXXXXXXXX) # Something like this? I've been reading the official documentation, but can't find how to: Get available versions of an object Retrieve one specific version Any help is appreciated. -

how to deal with dynamic items that are used on the base.html in Django
I have some dynamic fields on the base.html like the footer text and the social accounts links, but I need to fetch them from the database and send them alongside with each response for a view that uses a template which extends the base.html template. right now I am fetching the needed Items on every view and send them alongside with the view context, but I feel that this is repetitive, especially if I have more dynamic items, I tried also to save them to the request session but also it will require more code and edge cases. what is the most efficient way to fetch these items once and be able to use them on all the views that extends the base.html template? -
How to load data from a model into django settings.py variable?
I am writing a django application where I have a model called Website which contains websites of people. I only allow people who have their websites in my database to use my Django REST API. I am using the django-cors-headers package to whitelist the domains of people: https://github.com/adamchainz/django-cors-headers. CORS_ORIGIN_WHITELIST variable in settings.py allows me to white list domains as shown in https://github.com/adamchainz/django-cors-headers#cors_origin_whitelist The problem is that I have to query my models to get the website domains, append them to a list and then put that list into CORS_ORIGIN_WHITELIST. But I can't do that in settings.py because models are loaded after the app starts and settings.py is the one that starts the app. Does anyone know a way around that? Any suggestions will be appreciated. Thanks in advance. -
