"Right" way to define helper functions for Django models' Meta classes
I'm trying to simplify a very verbose and repetitive Check constraint for a model, whose logic is currently very hard to parse, factoring out and aptly renaming the repetitive parts. Basically I want to turn this (simplified and abstracted snippet): class MyModel(models.Model): class Meta: constraints = [ models.CheckConstraint( check = ( ( models.Q(foo = True) & ( ( models.Q(field1 = 'X') & models.Q(field2 = 'Y') & models.Q(field3 = 'Z') ) | ( models.Q(field4 = 1) & models.Q(field5 = 2) & models.Q(field6 = 3) ) ) ) | ( models.Q(foo = False) & ( ( models.Q(field1 = 'X') & models.Q(field2 = 'Y') & models.Q(field3 = 'Z') ) | ( models.Q(field4 = 4) & models.Q(field5 = 5) & models.Q(field6 = 6) ) ) ) ), name = 'foo', ), ] Into this: class MyModel(models.Model): class Meta: constraints = [ models.CheckConstraint( check = ( ( models.Q(foo = True) & ( condition1 | condition2 ) ) | ( models.Q(foo = False) & ( condition1 | condition3 ) ) ), name = 'foo', ), ] What I've tried / thought of trying: Factoring out the conditions, both as attributes and methods in Meta itself; that didn't work: TypeError: 'class Meta' got invalid attribute(s): condition1,condition2,condition3; Factoring … -
How to display multiple lines of text in django admin for Headers?
Similar questions that have already been asked are for data fields like in Here and Here But how to split the header in multiple lines? Considering a Django app with model and admin setup like this: models.py from django.db import models class TaskItem(models.Model): group = models.ForeignKey(TaskGroup, on_delete=models.CASCADE) title = models.CharField(max_length=32, null=False, blank=False) description = models.CharField(max_length=45, null=False, blank=False) reward = models.IntegerField(default=1000, null=False, blank=False) admin.py class TaskItemAdmin(admin.ModelAdmin): list_display=['title', 'group', 'reward'] list_filter=('group',) How can I rename headers to Task Title, Task Group and Task Reward with line breaks? -
How to update a list of To-Do items with checkboxes and save changes using React and Django?
I am trying to update a list of To-Do items using React for the frontend and Django for the backend. Each item has a checkbox to mark it as complete or incomplete. When I click the "Save" button, I want the updated data to be sent to the backend via a PUT request. However, I am facing issues with updating the items properly. Here’s my React handleSave function that triggers the PUT request: const handleSave = async (e) => { e.preventDefault(); console.log('handleSave called'); const updatedItems = items.map((item) => { const checkbox = e.target[`c${item.id}`]; console.log(`Processing item id ${item.id}, checkbox value:`, checkbox?.checked); return { id: item.id, todolist: 1, text: item.text, complete: checkbox ? checkbox.checked : false, duration: item.duration, }; }); try { console.log('Payload to send:', updatedItems); const response = await axios.put( `${import.meta.env.VITE_API_URL}/todo-items/1`, // Update the endpoint if needed updatedItems, { headers: { 'Content-Type': 'application/json' }, // Set proper headers } ); console.log('Items updated successfully:', response.data); } catch (error) { console.error('Error updating items:', error.message, error.response?.data); } }; Here’s the Django view handling the request: @api_view(['GET', 'PUT']) def todo_items(request, id): try: ls = ToDoList.objects.get(id=id) except ToDoList.DoesNotExist: return Response({"error": "List not found"}, status=404) if request.method == 'GET': incomplete_items = ls.item_set.filter(complete=False) complete_items = ls.item_set.filter(complete=True) items = … -

Annotate multiple values as JSONObject - parse datetime
I'm annotating my QuerySet as follows, using JSONObject, to obtain multiple fields from Scan: MyModel.objects.annotate( myscan=Subquery( Scan.objects .all() .values(data=JSONObject( id='id', nin='nin', datetime='datetime') )[:1] ) ) I want to get a proper datetime representation though, somehow. When I try to use myscan.datetime, I get the string representation (e.g. datetime': '2024-12-31T09:19:30.221953+00:00. How can I either return the datetime object itself (instead of a string; assuming this is impossible when using JSONObject) or alternatively do a strptime() before returning the string as part of the JSON? Obviously I could parse the string, convert to datetime and then do strptime() again, but that seems like a dirty solution. Any suggestions? -
Django - javascript - ajax does not work with javascript created lines

social_core.exceptions.MissingBackend: Missing backend "google-oauth2" entry in Django with Google OAuth2
I'm working on integrating Google OAuth2 in my Django REST Framework project using django-rest-framework and social-django.

VSCode Test Explorer hangs despite no errors in the output & all tests being collected (in the output)
I have been having a lot of issues with Test Explorer in VSCode. It has been working fine up until last week. I was writing new tests and clicked "Refresh Tests" and then it suddenly (and pretty randomly) stopped working - specifically it "discovers" tests forever.

How to dynamically create and manage SQL-like tables, data, and relationships in a MongoDB-based system?
I'm building a web application where users can execute SQL queries on predefined tables for an exam module. The backend is in Django, and the database is MongoDB. I want to allow admins to dynamically: Create table schemas (table name, columns, data types, primary keys). Insert data into these tables. Define relationships between tables (e.g., foreign keys). Validate and execute SQL queries submitted by users based on the stored table schemas and relationships. The goal is to minimize backend involvement by providing a user-friendly admin interface for managing tables and relationships. I am looking for best practices or suggestions on: Efficiently storing table schemas and relationships in MongoDB. Dynamically executing and validating SQL-like queries based on these schemas. Simplifying the admin interface for managing tables and relationships in the frontend. Any advice, code snippets, or recommended libraries/tools would be appreciated. -
Gmail with Oauth rejects my token/password
I am trying to send mail from Django. I've tried two different ways, both of which fail in different ways. When I tried using an app password, I had no errors, but the email just never arrived. And the sender's outbox is empty, too. But that was after I tried the modern method, OAuth. After a process that I would never have finished without ChatGPT (because nobody else has created a guide that I can find), I set up something that almost works. I have a file with a refresh token in it, and a custom backend that uses it. But when it's time to send an email, I'm told "Username and Password not accepted." Here's what the token file is like: { "token": "[secret]", "refresh_token": "[secret]", "token_uri": "https://oauth2.googleapis.com/token", "client_id": "[secret]", "client_secret": "[secret]", "scopes": ["https://www.googleapis.com/auth/gmail.send"], "universe_domain": "googleapis.com", "account": "", "expiry": "2025-01-05T07:39:06.980351Z" } And this is the backend: from google.auth.transport.requests import Request from google.oauth2.credentials import Credentials from django.core.mail.backends.smtp import EmailBackend from pathlib import Path import os class GmailOAuth2Backend(EmailBackend): def _get_access_token(self): dir = Path(__file__).resolve().parent file = os.path.join(dir, 'oauth2tokenfile.secret.json') creds = Credentials.from_authorized_user_file(file) if creds.expired and creds.refresh_token: creds.refresh(Request()) return creds.token def open(self): self.password = self._get_access_token() super().open() And finally, my settings EMAIL_BACKEND = "[secret].GmailOAuth2Backend" EMAIL_HOST … -

page not found error when using python social auth login for okta
I am getting a "Backend not found" error when trying to setup okta oidc login using social-auth-app-django 5.4.2 here are the settings: 'social_django' is added to INSTALLED_APPS 'social_django.middleware.SocialAuthExceptionMiddleware' is added to MIDDLEWARE "social_django.context_processors.backends" and "social_django.context_processors.login_redirect" are added to the list in TEMPLATES['OPTIONS']['context_processors'] AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.ModelBackend', 'social_core.backends.okta_openidconnect.OktaOpenIdConnect', ] LOGIN_URL = 'auth/login/okta_openidconnect/' and in the list of project urls, this is added path('auth/', include('social_django.urls', namespace='social')) when i go to the login url, I get a 404 page not found error Backend not found Request Method: GET Request URL: https://my.site/auth/login/okta_openidconnect/?next=/en-us/ Raised by: social_django.views.auth Using the URLconf defined in xxx.urls, Django tried these URL patterns, in this order: ... 17. en-us/ auth/ login/<str:backend>/ [name='begin'] The current path, en-us/auth/login/okta_openidconnect/, matched the last one. there are other settings, like SOCIAL_AUTH_OKTA_OPENIDCONNECT_KEY and the SOCIAL_AUTH_PIPELINE, which i'm sure are correct and i believe that even if they were not correct, it's unrelated to not having the proper backend. so does anyone see a mistake in this setup that could be causing the backend fail? -
playwright with django: 502 Bad Gateway Error
My webapp doesn't work for any portion that uses playwright. Everything works in localhost (including playwright). When trying to view the home page (no playwright), it works 100%. When trying to use code from the library playwright, it gives me a: 502 Bad Gateway nginx/1.18.0 (Ubuntu) What can I do to troubleshoot this? I tried disabling firewall, but that didn't make difference. I tried debugging by throwing an exception for each line of code. Sometimes it moves a few lines further and other times it doesn't move a few lines further. Again, only code that uses playwright will give me this error. I'm using Django 5.1.4. Playwright is latest version.

Need help fixing a Django 404 error, not finding a static page using URLConf
My Django project is a single-application website where the homepage shows articles/posts from my database, and will have pages for tag topics and year/month archives. All other pages are static pages for photo and video galleries, and an about page — they don't use the database at all.

Django query is case sensitive after moving to MariaDB
I have a Django project that can perform a query using a person's name as show in the attached code. def get_queryset(self): query = self.request.GET.get('query') if query: query = " ".join(query.split()) if query.isdigit(): qs = Patient.objects.filter(Q(full_name__contains=query) | Q(patient_id__contains=query)).order_by('patient_id') else: qs = Patient.objects.filter(Q(full_name__contains=query) | Q(patient_id__contains=query)).order_by(Lower('full_name')) else: qs = Patient.objects.order_by(Lower('full_name')) return qs This works in a case insensitive manner in SQLite3, which is what I want. I recently moved the project to MariaDB and now the query is case sensitive. I have checked to collation on the database, table, column, ... and it is set to utf8mb3_general_ci which by my understanding should result in a case insensitive search. Interestingly enough, doing the interactive query: select full_name from patients_patient where full_name like 'ana maria%'; results in a case insensitive search. Any ideas why the query in my code is case sensitive and how to make it case insensitive? -

Product cards are not displayed in categories
There was a problem in displaying products that are sorted by category in the "Products by category" section of the site. The display of goods by category is prescribed in "list.html ". Views have been created for these products, but the product cards themselves are not displayed. That's the problem. I guess I made a mistake somewhere in the cycles, and now these product cards just don't appear. I did a review, but I didn't find anything.. I ask you to help me with this problem, I will be grateful.

Here is the model: class TobaccoUse(models.Model): tu_id = models.AutoField(primary_key=True) patient_id_fk = models.ForeignKey('patient_management.PatientInformation', on_delete=models.CASCADE) SMOKING_STATUS_CHOICES = [ ('N', 'Never Smoked'), ('P', 'Past Smoker'), ('C', 'Current Smoker') ] tu_smoking_status = models.CharField(max_length=1, choices=SMOKING_STATUS_CHOICES) OTHER_USE_CHOICES = [ ('P', 'Pipe'), ('C', 'Cigar'), ('S', 'Snuff'), ('CH', 'Chew') ] tu_other_use = ArrayField(models.CharField(max_length=2, choices=OTHER_USE_CHOICES, null=True, blank=True), size=4, default=list, null=True, blank=True) tu_packs_per_day = models.DecimalField(blank=True, null=True, max_digits=4, decimal_places=1) tu_years_smoked = models.PositiveSmallIntegerField(blank=True, null=True) tu_quit_date = models.DateField(blank=True, null=True) tu_is_active = models.BooleanField(default=True) The view: class ListTobaccoUseOptions(APIView): def get(self, request): statusChoices = [] otherChoices = [] for ssc in TobaccoUse.SMOKING_STATUS_CHOICES: statusChoices.append({'label': ssc[1], 'value': ssc[0]}) for soc in TobaccoUse.OTHER_USE_CHOICES: otherChoices.append({'label': soc[1], 'value': soc[0]}) try: smoking_status_categories = {'status_categories': statusChoices, 'other_use_categories': otherChoices} return Response(smoking_status_categories, status=status.HTTP_200_OK) except Exception as e: return Response(data={'error': str(e)}, status=status.HTTP_400_BAD_REQUEST) And the serializers: class PatientMedicalHxSerializer(serializers.ModelSerializer): prognosis = serializers.SerializerMethodField() primary_diagnosis = serializers.SerializerMethodField() surgical_diagnoses = serializers.SerializerMethodField() secondary_diagnoses = serializers.SerializerMethodField() wellness_screenings = serializers.SerializerMethodField() tobacco_use = serializers.SerializerMethodField() vape_use = serializers.SerializerMethodField() class Meta: model = PatientInformation fields = ('primary_diagnosis', 'secondary_diagnoses', 'surgical_diagnoses', 'prognosis', 'wellness_screenings', 'tobacco_use', 'vape_use') def get_primary_diagnosis(self, patientinformation): qs = PatientToPrimaryDiagnosis.objects.filter(patient_id_fk = patientinformation, ptpd_is_active = True) serializer …
