Ordered Many-To-Many Custom Through Table, Now Field Has Duplicates
As the title indicates, when I try to order by my custom through table, the field now shows duplicates. It seems to be doing a left outer join, displaying all fields on both sides instead of showing only unique values, and distinct() seems to do nothing here. I'm using sqlite3 and distinct('field-name') isn't supported with sqlite3. Here's a dumbed-down summary of my code, showing only relevant fields: # Models class DataRepository(Base): class Meta: ordering = ('-updated_at',) name = models.CharField(max_length=100, unique=True) class Dataset(models.Model): class Meta: ordering = ('-updated_at',) name = models.CharField(max_length=100, unique=True) # Dataset name must be unique across BrainSTEM datarepositories = models.ManyToManyField(DataRepository, through="DatasetDatarepository", blank=True) # Data repositories where the data from this dataset is stored. Create private data repositories [here] class DatasetDatarepository(models.Model): class Meta: ordering = ('order',) unique_together = (('dataset', 'datarepository'),) dataset = models.ForeignKey(Dataset, on_delete=models.CASCADE) datarepository = models.ForeignKey(DataRepository, on_delete=models.CASCADE) order = models.PositiveIntegerField(null=True, blank=True, default=0) # Admin class DatasetAdmin(admin.ModelAdmin): fieldsets = ( (None, {'fields': ( 'name', 'datarepositories', )}), ) form = DatasetForm # Form class DatasetForm(forms.ModelForm): class Meta: model = Dataset fields = [ "name", "datarepositories", ] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.fields.get('datarepositories', None): datarepositories = self.fields.get("datarepositories") dr = DataRepository.objects.none() projects = self.instance.projects.all() for project in projects: for group … -

Django docxtpl subdoc merging doesn't merge all content
So I'm having a really annoying issue with django and docxtpl. I have a few placeholders in my document that I'm trying to replace. The placeholders content consists of html content. Im firstly setting this content in a subdoc based on the main doc (which works, the document is being saved and all the content that has been provided in the placeholder is inside of the sub_doc). Then Im trying to merge it, and here is where it gets really weird. As you can see I'm saving the merged document document.save("end_doc/doc.docx") # Save for local inspection. For some reason when I open this file it's empty. But my function returns the document in memory as you can see, in that file there is some content but it's missing some. So for example. If my placeholders content has a few elements, such as 5 <p> tags. It only shows 1 <p> tag in the merged file. But in the sub doc it shows every single tag. Thanks in advance from docx import Document from docxtpl import DocxTemplate from htmldocx import HtmlToDocx from docx import Document as _Document def convert_placeholders_to_text_in_doc(document, context, document_name): document = DocxTemplate(document) sub_docs = {} for placeholder, html_content in … -

Browser Not Saving HttpOnly Cookie React/Django
I have a netlify frontend at app.mydomain.com, and a django ninja REST API at api.mydomain.com. When I submit to my login endpoint, the api returns successfully with the access key (which I store in app state) and a refresh token in the form of a secure, httponly cookie. I can see this cookie is returned by looking in the response headers in dev tools. The cookie however is not stored by the browser at all, I've gone through numerous other questions/answers and I believe I have implemented everything required, but it's still not working. My login API call from the frontend is: await fetch( AUTH_URL_OBTAIN, { method: RequestMethod.POST, headers: {"Content-Type": "application/json"}, body: JSON.stringify({username: formData.email, password: formData.password}), credentials: "include", }, ); On the backend, the cookie is set like this: response.set_cookie( key="refresh", value=refresh_token, expires=datetime.fromtimestamp(refresh_token_payload["exp"], timezone.utc), httponly=True, samesite="none", secure=True, path="/api/auth/web/token-refresh", domain=".mydomain.com", ) I also have the following settings set (substituting the values in for environment variables): CSRF_TRUSTED_ORIGINS = ["https://app.mydomain.com"] CORS_ALLOWED_ORIGINS = ["https://app.mydomain.com"] CORS_ORIGIN_WHITELIST = ["https://app.mydomain.com"] CORS_ALLOW_CREDENTIALS = True The login response provides the access token (which works as expected - I am able to make API calls using this just fine, and have credentials: include on all fetch requests) and the response … -
Trouble with Django migrations: No new migration files created despite all migrations applied
I am encountering an issue in my Django project where new migration files are not being created despite all migrations being applied. I have checked several possible causes, including database schema consistency, migration naming conflicts, and migration autodetection settings, but have not been able to resolve the issue. Problem Details: After running the makemigrations and migrate commands in Django, I expect to see new migration files created in my app's migrations directory. However, even though Django reports that all migrations are applied successfully, the expected migration files (0001_initial.py, 0002_something.py, etc.) are not generated.

Ai chatbot in django using WitAI is only answering "There was an error processing you're request" to every question How do i fix that
I'm developing a chatbot using the Wit.ai API in a Django application. The chatbot interface is implemented in HTML and JavaScript. The bot is designed to take user input, send it to the Wit.ai API, and display the response. However, every time I send a message, the bot replies with "There was an error processing your request." I've double-checked the Wit.ai API call, and it seems to be correct. I suspect that the issue might be with how the response is handled or an issue with the authorization token. Below is the code for my HTML and JavaScript implementation: (Please don't use this code i've worked really hard on this) <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Intra AI Chatbot</title> <style> body { font-family: Arial, sans-serif; background: linear-gradient(to bottom right, #4a00e0, #8e2de2, #4a00e0); color: #fff; margin: 0; padding: 0; display: flex; flex-direction: column; align-items: center; min-height: 100vh; /* Ensure full viewport height */ overflow: hidden; /* Hide overflow for shapes outside viewport */ position: relative; /* Set position to relative for absolute positioning of shapes */ } /* Animation keyframes */ @keyframes moveCircleUpDown { 0%, 100% { transform: translateY(0); } 50% { transform: translateY(-20px); } } @keyframes moveCircleLeftRight … -

Implementing Centralized Authentication with JWT in Django Tenants
I'm developing a Django project that utilizes Django tenants for multi-tenancy management. I have implemented JWT authentication using rest_framework_simplejwt for user authentication. Now, I'm looking to centralize authentication across all tenants. I want to implement a single sign-on (SSO) solution where users can authenticate once and access all tenant resources without needing to log in separately for each tenant. However, I'm facing challenges integrating this with Django tenants and ensuring secure authentication. Current Setup: Here's an overview of my current setup: Django version: [5.0.4] Django tenants version: [3.6.1] Installed packages related to authentication: [simple jwt] Desired Solution: I'm seeking guidance on how to implement centralized authentication using JWT in Django tenants. Specifically, I want to: Understand the best practices for implementing SSO with Django tenants. Determine how to modify my existing JWT authentication setup to support SSO. Ensure that authentication is secure and user sessions are managed appropriately across tenants. Additional Information: Are there any potential security concerns I should be aware of? Are there any limitations or challenges with integrating SSO in Django tenants that I should consider? Any advice, code examples, or references to relevant documentation would be greatly appreciated. Thank you! -

Whats the use of DSA in real world application?
Okay, I might sound stupid but I'm trying to understand the real-world application of DSA? I started learning DSA but I didn't know what I'm gonna make once I learned the whole thing? I'm a full stack developer and I know if there is a frontend developer his work is to code a site from a figma file or take the API coming from the backend and use Redux or other state management to do stuff or if there is a backend developer I know his work is to make backend parts building APIs working with DB and other stuff... But after learning DSA what I'm gonna build? What kind of work am I gonna do? Or after learning where I can use my DSA knowledge in my web apps? All I see are people talking about FAANG companies online and I haven't found that many videos or blogs on some DSA project in python. Can someone please clear my doubts it would be really appreciated I'm so confused right now. -
Django startproject [WinError2]
This is my first time using django so maybe I am missing something obvious. When I try to create a new project using command django-admin startproject main i get this error CommandError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\edgar\\Documents\\main'. I thought django creates this directory? That's what I see in all tutorials. Very confused I tried running command prompt as an administrator as well as uninstalling and reinstalling django. Also tried reinstalling python which still didn't work. Tried running in VSCode terminal. Nothing seems to be working. If I manually create the directory then i get an error saying 'manage.py' does not exist in the directory. -
Python - Django - MySQL #need to add distinct() after select_related().distinct() in views.py
class AdListView(ListView): model = Ad # Specify the model you're working with template_name = "ads/ad_list.html" def get(self, request): strval = request.GET.get("search", False) if strval: query = Q(title__icontains=strval) query.add(Q(text__icontains=strval), Q.OR) ad_list = Ad.objects.filter(query).select_related().distinct().order_by('-updated_at') else: ad_list = Ad.objects.all().select_related().distinct().order_by('-updated_at') # Apply distinct() explicitly ad_list = ad_list.distinct() if request.user.is_authenticated: favorites = list(request.user.favorite_ads.values_list('id', flat=True)) else: favorites = [] for obj in ad_list: obj.natural_updated = naturaltime(obj.updated_at) ctx = {'ad_list': ad_list, 'favorites': favorites, 'search': strval} return render(request, self.template_name, ctx) so this is ads/views.py there's a ads/models.py, ads/forms, ads/urls.py and other files, but the one that the grader is complaining is this views.py... 3806 characters of HTML retrieved Test completed: Found menu bar at the top of the page Found more than one ad when searching for 'HHGTTG_42 1717639962'. You probably need to add distinct() after select_related().distinct() ... in your views.py so i tried using the select_related().distinct() and adding it after, but is not working :( -
Django: Better way to process data from my models.py than doing it in my views.py
Currently, I am processing a lot of information in views.py, which feels like the incorrect place to do it. Is there a better/place way to process this information?

Change widget of modelformset field to RadioSelect without defining a form object?
In Django, I am instantiating a modelformset as follows (straight from here): MyFormSet = modelformset_factory( MyModel, fields=["one", "two", "three"], extra=0) fs = MyFormSet(queryset=MyModel.objects.filter(field=a_value)) So, no form object at all, it just picks the fields I want. However, one of those fields (say "two") is rendered as a drop-down, and I want it as a RadioSelect. Is there a way to change the widget of "two" to RadioSelect in a simple way, or do I have to declare a form object to customize that?
