CSRF token not generated in django backend
I have a web application that I built using a Vuejs for the frontend and django for the backend. When I was developing the application, I did not have issues in regards to csrf token generation. I have only begin encountering this issue 2 months after development. I am not sure why this issue is happening, or what was the behaviour for setting the csrf token when I was developing it. As far as I understand, an initial get request to the backend sets the csrf token in the browser, and can then be used by all other subsequent requests. But I do not see any csrf cookie in the applications tab. I have this method for setting the csrf cookie in the backend: def get_csrf_token(request): return JsonResponse({"detail": "CSRF cookie set"}) and this is where I call the method in my frontend: onMounted( async()=>{ const response = await fetch('http://127.0.0.1:8000/get-csrf-token', { method: 'GET', credentials: 'include' // This ensures cookies are sent with the request }); console.log if (response.ok) { console.log("CSRF token set successfully."); } else { console.log("Failed to set CSRF token."); } }) this is my setting.py file if its needed: """ Django settings for api project.

Add pyproject.toml to Django apps that are part of a source tree
I have a Django application which consists of two Django 'apps' - the term used in the Django world for (potentially) reusable packages. My whole application lives in one git repository. I would like to use one of the apps in another Python application. Specifically, I want to use the Django ORM and need to use the models definied in that app. Currently I put the parent directory of the app onto my sys.path and it works fine. But I would like to be able to pip install that app. My directory layout looks like this: website/ website/ <- main Django app settings.py urls.py ... crawls/ <- app I want to share views.py urls.py pyproject.toml <- this is new ... other_app/ <- application where I want to use `crawls` What I tried now is to place a pyproject.toml into crawls. However, both hatchling and flit seem to insist on an additional subdirectory. For example, the following results in ValueError: No file/folder found for module gen_crawler_crawls: [build-system] requires = ["flit_core >=3.2,<4"] build-backend = "flit_core.buildapi" [project] name = "gen-crawler-crawls" dependencies = [ "Django>=5.0.6", ] requires-python = ">=3.12" authors = [ {name = "Homer Simpson", email = "homer.simpson@example.com"}, ] dynamic = ["version", "description"] … -

How to annotate after group by and order_by in django?
I have a DB table which has a field "created_at". This is a auto_now_add=True field. This table is inserted data once everyday. What I want to do is filter data that corresponds to the last day of each month of each year. I have a query as follows: qs = ( self.model.objects().with_months() .with_years() .values('year', 'month') .annotate(last_day=Max('created_at')) .order_by('year', 'month') ) with_months() and with_years() methods are queryset methods that annotate year and month. What I want to do is to annotate other fields of this model in this queryset; however, since values() returns a list of dictionaries, I am not able to do that. I cannot add other fields inside values() as they won't be grouped. How can I achieve this? Best -

how to send data returned from a function to client in django in real time without the client need to refresh
I am writing a program to retrieve data and display it in a Django template. I have a function called match_algo() that takes a long time to run. I want to initially show 'Loading...........' on the page, and once the function completes and returns the result, I want to display the retrieved content on the page. This is the view I tried first : def redirected_page(request): data = match_algo() context = { 'data' : json.dumps(data), 'test' : 'test' } return render(request , 'redirected_page.html' , context ) After some research, I found that WebSockets might help with this, but I'm still not sure if it's the solution I need. This is my consumer.py: class LoadingConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() # Send "loading..." message when the connection is established await self.send(text_data=json.dumps({ 'message': 'loading...', "status" : False })) data = match_algo() # Send "loading completed" message after processing is done await self.send(text_data=json.dumps({ 'message': "loaded", "status" : True, # "matches" : data })) # Close the connection after sending the final message await self.close() for testing purpose I commented this line data = match_algo() then added time.sleep(5). this actually works.

Djagno ORM diacritic and case insensitive query with matching at least 3 chars
I'd like to quiry the columns "title" and "content" of the following django model w postgresql integration in a diacritic- and casing-insensitive way. The query should return articles when the string "Ronald" is present in either of these columns, for every of the following user inputs: "ronálD", "Ron" and even "ronald reagan" for example. class Article(models.Model): date = models.DateField() content = models.TextField() title = models.CharField(max_length=300) category = models.CharField(max_length=50) length = models.IntegerField(default=4, null=True) thumbnail = models.TextField(null=True, blank=True) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) img_location = ArrayField(models.TextField(), blank=True, default=list, null=True) Thanks for the assistance! I came as far as returning articles casing and diacritic-insensitively w substring mathcing, but did not manage to return articles when only a set of letters are matching: eg: "Reagen" for the input "Ronald Reagan", or when querying multiple columns: from django.db.models import Func, Value, F, Q class Unaccent(Func): function = 'unaccent' class Lower(Func): function = 'lower' def normalize_field(field_name, is_array=False): if is_array: return Unaccent(Lower(F(field_name), function='unnest')) return Lower(Unaccent(F(field_name))) normalized_term = Lower(Unaccent(Value(input_term))) articles = list(Article.objects.annotate( normalized_content=normalize_field('content'), ).filter( Q(normalized_content__icontains=normalized_term) ).order_by("-id").values()[:20]) -
Switching execution engine from Celery to Kubernetes for my django app
In my current Django application i'm using celery to execute my tasks. After knowing capabilities of kubernetes i want to switch from celery to Django. I have implemented one architecture but it is incomplete I'm using docker to host BE and FE which is primarily outside k8s cluster, I have define a message broker like redis same as celery which keeps track of new task, after receiving task my kube.py will generate pod in k8s cluster and will execute that task. This was the overview of my current architecture Note: My app is monolithic (don't want to convert it to microservice for some reason) My concerns are straight forward. How can i pass tasks from my native application to k8s cluster how to keep track of tasks i.e success, failed if failed i want to re-execute it how to keep logs, i want to keep one pod running at all time i want to scaleup and scale down pods based on tasks available -
Encoding cookies in Django
It seems like Django does not encode my cookies properly I tried using: resp = request.get_signed_cookie('age', salt='code') However the output for number '20' would be '20:1sl4MF:RUUEG71gABt4-MeCj_lZiuklArWiCOLTKsxKfjLvlUg', meaning that the value is still visible, and the code just adds ':' and a bunch of characters. Same goes for other numbers and strings. Is it normal or am I doing something wrong? -

Model inheritance with existing DB models. Migration issue with “_prt” field
I’ve started to refactor some legacy code and having some difficulties with Model Multi-Table Inheritance on existing model. Let’s say I have a parent class Item: class Item(models.Model): brand = models.CharField(null=True, blank=True) model = models.CharField(null=True, blank=True) category = models.CharField(ItemCategory, null=True, blank=True) I have a child class Phone: class Phone(Item): serial_number = models.CharField() price = models.PositiveIntegerField() For a transition period I’ve allowed Item fields to be null=True and blank=True for a later manual population. However during a migration call I receive it is impossible to add a non-nullable field 'item_ptr' to phone without specifying a default. I understand a nature of this warning as django doesn’t know where to link item_ptr which hides under the hood and links to Item model with OneToOne relation. So I have a dummy Item instance I want to use for linking but how to point the Item id/pk on the console with choosen option 1 as it doesn’t recognize raw int as pk. Is it possible overall or the way is to manipulate with migrations manually? I don't see the option of dropping DB as it's already contains important data. -

Here’s the output from the console.log() when the request is made in the created hook: This should succeed from hook [{…}]length: 0[[Prototype]]: Array(0) However, when I make the same request by clicking a button, the response data is correct: <button @click="getNotif">Get new notifi</button> getNotif() { this.$http.get('/notifications/').then(response => { console.log('This should succeed', response.data) }) .catch(error => { console.error('Error captured:', error) }) } Here’s the console.log() output from the button click: This should succeed [{…}]0: {id: 2, message: 'test first notification', created_at: '2024-08-29 07:48'}length: 1[[Prototype]]: Array(0) On the Django side, the API seems to work fine: class BusinessNotificationView(APIView): permission_classes = [IsAuthenticated] serializer_class = NotificationSerializer def … -
replace in old project exists Django User model to my User model
I have an old project in which there is a user model that was made by default. Next, we were asked to change the default user model. We have redefined the user model as: class Staff(AbstractUser): # ... new fields ... # no need in model user_permissions = None groups = None class Meta(AbstractUser.Meta): db_table = 'auth_user' swappable = "AUTH_USER_MODEL" Next, we added it to the settings.py file: # user model AUTH_USER_MODEL = 'test.Staff' # django authentication backend AUTHENTICATION_BACKENDS = [ # 'django.contrib.auth.backends.ModelBackend', # Django's default authentication backend 'test.backends.ModelBackend', # Custom authentication backend ] the necessary lines and we can't start the migration (just re-run for tests). ValueError: The field admin.LogEntry.user was declared with a lazy reference to 'test.staff', but app 'test' doesn't provide model 'staff' Please tell me how to properly replace users in django. -
React How to get all free available plugins and tools for CKEditor, similar to Django

When does Djangos CONN_MAX_AGE get checked/used?
I recently had a "Too many connections" issues of my Django+Celery application with a Postgres DB on Heroku. Could dyno restarts be the issue? The idea is that the dyno restart drops the connection, but Postgres keeps them. Setting CONN_MAX_AGE seems to have solved the issue, but I'm uncertain. The question now is: How does CONN_MAX_AGE work? (1) Does Django actively check the age of the connection and close + restart it when it's too old or (2) Is CONN_MAX_AGE a parameter of the connection itself, so that postgres automatically closes the connection after that time? -
MySQL Authentication Plugin Issues on macOS
I’m working on a blog project using Python and Flask, and I’m using the MySQL database from XAMPP for user registration. The project worked perfectly on my Windows machine, but after switching to macOS, I’ve been encountering various issues with the registration process. I’ve managed to resolve most of the issues, but I’m still struggling with one particular error. I’ve been working on this for a week now and could use some help. Error Details: MySQLdb.OperationalError: (2059, "Authentication plugin 'mysql_native_password' cannot be loaded: dlopen(/opt/homebrew/Cellar/mysql/9.0.1/lib/plugin/mysql_native_password.so, 0x0002): tried: '/opt/homebrew/Cellar/mysql/9.0.1/lib/plugin/mysql_native_password.so' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/opt/homebrew/Cellar/mysql/9.0.1/lib/plugin/mysql_native_password.so' (no such file), '/opt/homebrew/Cellar/mysql/9.0.1/lib/plugin/mysql_native_password.so' (no such file)") enter image description here Context: • The application is running on macOS using XAMPP. • The database is configured correctly, and I can connect to it using other tools. • I’ve tried various solutions like asking chatgpt or searching on google Has anyone encountered this issue or have any suggestions on how to resolve it? Thanks in advance for your help! -
Should authentication_classes and permission_classes in Django's APIView Be Defined with Lists or Tuples?
I'm trying to understand the best practice for setting authentication_classes and permission_classes in Django's APIView. Specifically, I’ve seen both tuples and lists being used to define these attributes: Using a tuple: class Home(APIView): authentication_classes = (JWTAuthentication,) permission_classes = (permissions.IsAuthenticated,) Using a list: class Home(APIView): authentication_classes = [JWTAuthentication] permission_classes = [permissions.IsAuthenticated] Both approaches seem to work correctly, but I'm unsure if there are any specific reasons to prefer one over the other. Should I use a list or a tuple in this scenario? Are there any implications for using one over the other in terms of performance, readability, or following Django's best practices? I tried using both tuples and lists for authentication_classes and permission_classes in Django’s APIView. Both work fine, but I’m unsure which one is better or recommended. I was expecting to find clear guidance on this.
