django.db.utils.DatabaseError when updating upvotes of a post
I've created a reddit-like clone web that accept users upvotes and downvotes for both post and comments, however, I keep getting a databaseError. I am using djongo to connect to my mongodb atlas. Everything is working with djongo until I add the upvote/downvote features. I think that my votes up/down calculation updates are correct, I've updated urls.py. The issue is at self.save().

Generate pdf with bootstrap in django
I'm trying to generate a PDF by providing an HTML page in my Django project. I have previously used the pisa library of xhtml2pdf but failed to load bootstrap.

Is modifying Django urlconf via set_urlconf and request.urlconf in a middleware safe?
I am changing the default urlconf in a middleware based on the requested hostname and it's working as expected during development, however I am concerned about racing/threads as I am modifying a Django setting at runtime! My concern is that Django would confuse the urlconfs with many concurrent requests. Is that a valid concern? -

Set a reverse foreignkey relationship in django without saving
if you have an instance of a django object, you can set a field and if you don't save it, it goes away. if you have a foreignkey relationship and you use set, clear, etc. the change you made is immediately written to the db. this makes sense, but is there a way not to do this. As in to temporarily modify the relationship objects, similar to what you can do for a charfield, etc. https://docs.djangoproject.com/en/3.1/topics/db/examples/many_to_many/ class Foo(model): name = charfield() class Bar(model): name = charfield() foo = Foreignkey(Foo, related_name="bars", null=True) bar1 = Bar.objects.create(name="bar1") bar2 = Bar.objects.create(name="bar2") foo = Foo.objects.create(id=1, name="dog") foo.bars.add(bar1) foo.bars.add(bar2) foo.name >> "dog" foo.name = "cat" foo.name >> "cat" len(foo.bars.all()) >> 2 foo.bars.clear() len(foo.bars.all()) >> 0 foo1 = Foo.objects.get(id=1) foo1.name >> "dog" len(foo1.bars.all()) >> 0. ---->>>> i want this to remain 2 -
modify the @login_required Decorator in Django to do authentication Role wise - Django, Python
I am working on a project in Django 3.1.2, here I have several models and views, and I have three entities admin, designer and customer. I have created customer and admin site separately, but the designer has some functionalities to modify some files, and entries in database from admin side.

How do I sort a Django queryset by frequency of occurance from a list and ensure the remaining objects follow?
I have a Django application running Django 3+ and Python 3.8+. I am trying to fill the front page of my site with relevant accounts to the user currently logged in. I have a list of common tags (belonging to the logged in user), let's call this: common_tags=['tag1','tag2','tag3'] This list can vary in length. My goal: I need to be able to query all my users and filter it in such a way that I get an ordered queryset where the users who have the most common_tags as their tags come up on top. That set of people need to be sorted by who has more tags in common (not based on how many of each tag they have, just the common occurrences with logged in user). This same query set should also contain the remaining users who do not have any of the common tags. Lastly, this queryset should not have any repeats. So far I have: relevant_accounts= User.objects.all()\ .annotate(count_resources=Count('resources')).order_by('-count_resources')\ .order_by(Case(When(resources__tags__name__in=common_tags, then=0),default=1, output_field=FloatField())) This appears to work, but I get repeated values. Running .distinct() does not resolve the issue. Edit: Sample Input/Output User A: Tags = ['A','A','B','C'] User B: Tags = ['A','B','B','C'] User C: Tags = ['A','B','B','B'] Sample User … -

Is it good to build SSO app with Django with multiple auth backend?
I'm wondering how good is to build SSO service written in Django with multiple backends (mobile phone + OTP, email + password) using JWT. Is there any best practices and some advices? How Django + Postgres will work together if there will be more than 10 000 users per day. I know all of these are scalable. But, I will be grateful for any architectural advices and recommendations at the beginning. -

Question how can I check is the post.author is a superuser or staff and if staff the name should be admin -
Django - Cannot pass id of Django form to javascript variable
So I read the django documentation and a django form field id should have the format id_(form field name), but when I try to reference this id when assigning the form field to a javascript variable it returns null. To test this, I used auto_id to make sure the id I used in javascript matches the field id I am trying to reference and it does. Additionally, I passed another html element ("testid") to my javascript to make sure it works with the rest of the elements in the template and it does. Why would I be able to assign the id of all of my html elements to a javascript variable but not the django form? forms.py (list of choices not included to save space) class FilterForm(forms.Form): dataset = forms.CharField(label='', widget=forms.Select(choices=DATASET_CHOICES)) graph_type = forms.CharField(label='', widget=forms.Select(choices=GRAPH_CHOICES)) html {% extends 'base.html' %} {% load materializecss %} {% block content %} <form action = "", method = "POST"> {{form|materializecss}} </form> {{form.graph_type.auto_id}} <div id = "testid"></div> {% endblock %} main.js const carInput = document.getElementById("id_graph_type") const testInput = document.getElementById("testid") carInput.addEventListener('change', e=>{ console.log('Changed') }) testInput.addEventListener('change', e=>{ console.log('Changed') }) -
