mysql: how to resolve duplicate key errot
My django project has a migration that creates a foreign key on a table. When the migrate command is executed, I receive a stacktrace with error : MySQLdb._exceptions.OperationalError: (1061, "Duplicate key name "..." I located the key in table_constraints and in table_constraints_extensions. It doesn't appear to be in any other constraint table. There is one instance of the same key in each table. The foreign key was created, and actually works, but the migration fails to complete due to duplicate keys. I'm just not sure exactly where the duplication is because the FK constraint appears once in each of the tables mentioned above. My project can function without doing anything further, but the migration process will be broken until I fix this in the db. How and where do I fix this problem? delete from table_constratins ... alter table projects_project drop constraint ... -
CSS making boxes too big and taking up all the required space
I'm using Django's HTML scripting to iterate through a list of tags from a ManyToManyField for an article. Getting the information works, but the actual sizing of the borders around the tags ends up being all wrong. The boxes are absurdly big. The titles also aren't where I want them to be, though that is on hold. The CSS is a combination of custom CSS and Tailwind (yes I know that's a bad practice, but I'm lazy). HTML: {% extends 'head.html' %} {% load static %} {% block content %} <h1 class="flex items-center justify-center text-6xl">Articles</h1> <br> {% if articles %} <div class="flex items-center justify-center"> <div class="posts"> {% for article in articles %} <a href="{{ article.get_absolute_url }}"> <div class="article_box"> <span>{{ article.article_title }}</span> <div> {% for tag in article.article_tags.all %} <div class="tag">{{tag}}</div> {% endfor %} </div> </div> </a> {% endfor %} </div> </div> {% endif %} {% endblock %} CSS: .posts { font-size: 20px; display: grid; gap: 4rem; grid-template-columns: repeat(3, minmax(0, 1fr)); padding-left: 12rem; padding-right: 12rem; } .posts div { aspect-ratio: 1; } .article_box { width: 3/12; border: 2px solid black; padding: 0.5rem; } .tag { border: 2px solid black; border-radius: 20%; padding: 0.25rem; margin: 0.15rem; } .tags { display: flex; flex-basis: … -
Is there a way to identify when a 'like' was put on a blog post?
I've got a standard blog post set up where users can like posts. I'd like to be able to work out which posts have had the most likes in a given time frame but I'm not sure how to identify when a like was attributed to a post. My Post model: class Post(models.Model): objects = PostManager() author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, default=None, null=True) title = models.CharField(max_length=100) description = models.TextField(max_length=500) date = models.DateTimeField(auto_now_add=True) likes = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name="post_like", blank=True) Other posts I've seen with a similar question have a Like model, is there a way I can do what I want using my current model or do I need to create a separate model for it? I was hoping to do something like adding auto_now_add=True to my likes attribute, similar to what I've done with date, but I know that only tells me when a blog post object was created. -
django celery tasks are executed before establishing a websocket connection
The user uploads the file to the form, after which the form with the file is sent to the server, and upon successful validation, I perform the following actions: def form_valid(self, form): storage = FileSystemStorage() file_path = storage.save(form.cleaned_data['file'].name, form.cleaned_data['file']) task = tasks.extract_text_from_pdf.delay(services.full_path(file_path)) return HttpResponseRedirect(reverse('pdf:download_result', kwargs={'task_id': task.id})) I temporarily save the file to the local file system and pass the file path to the celery task. After submitting the task to celeri, I redirect the user to another page where I establish a websocket connection to the server to be notified of the file processing result. In celery tasks, I open a file and perform the necessary actions with it, after which I send a message to the consumer. @shared_task def send_notification(message, task_id): channel_layer = get_channel_layer() room_group_name = f'download_result_{task_id}' async_to_sync(channel_layer.group_send)( room_group_name, { 'type': 'notification_message', 'message': message } ) @shared_task def extract_text_from_pdf(pdf_file_path): with open(pdf_file_path, 'rb') as file: reader = PdfReader(BytesIO(file.read())) text = "" for page in reader.pages: text += page.extract_text() + "\n" text = text.replace('\n', '\r\n') send_notification.delay(text, current_task.request.id) But I encountered a problem - celery tasks are executed faster than the websocket connection is established and as a result the message does not reach the client side. src.pdf_processing.tasks.extract_text_from_pdf[8f535575-803d-4679-8007-7a4404a372c1] succeeded in 0.148360932000287s: None … -
Resolving ImportError: Module "redis.connection" does not define a "HiredisParser" attribute/class
My django project has this issue after I updated my redis to version 5.4.0. It seems that the HiredisParser that I was using in my PARSER_CLASS in the redis configuration could not be found in this update. After taking a look at the change log, it seems the issue is a rename of the HiredisParser class from HiredisParser to _HiredisParser. So a simple change from this: "PARSER_CLASS": "redis.connection.HiredisParser" to this: "PARSER_CLASS": "redis.connection._HiredisParser" should fix the issue. Note that if hiredis package is already installed you can remove the whole line completely in your django cache configuration as it will by default select _HiredisParser if hiredis is installed. Relevant source: https://github.com/jazzband/django-redis/issues/676 -

how to generate a list of endoints using a specific func
In my django app I want to keep track of all endpoints that use a particular function inside them. Let's call the function caching_func. I encapsulate my endpoints inside view classes, such as this: class TemplateViewSet(GenericViewSet): @action( detail=False, methods=["GET"], ) def download(self, request, *args, **kwargs): """ Returns a Zip file with all generated template files. """ # Create a HttpResponse with the contents to download response = zip_file_download() # cache response caching_func(response) return response @action( detail=False, methods=["POST"], ) def upload(self, request, *args, **kwargs): """ Accepts an uploaded file """ response = do_upload_work() return response def get_queryset(self): return None You can see that caching_func is invoked inside the download endpoint but not inside the upload endpoint. When the server is started, I want to construct a list of the endpoints that use caching_func, and I want the output to be the full endpoint name, not just the method name. For instance, the snippet below is in the urls.py file of the app: router.register( r"template", TemplateViewSet, basename="download-template", ) urlpatterns = router.urls So if the final endpoint urls are /template/download/ and /template/upload/, then the list of endpoints that use caching_func should be ["/template/download"]. Please describe how you think I can achieve this. -

How long does the `httpx.AsyncClient` can "live" without closing the event loop?
I have an endpoint in Django that orchestrates a bunch of API calls to other underlying services. I intend to use a long-lived instance of httpx.AsyncClient - which will be ultimately responsible for the API calls. class Api: # for historical reasons, this class has both sync and async methods ... AsyncApi = partial(Api, async_client=httpx.AsyncClient(timeout=30)) class MyViewSet(viewsets.GenericViewSet): @action(...) def merge(self, request: Request) -> Response: ... result = async_to_sync(merge_task)(..., api=AsyncApi(jwt_token=request.auth)) ... I'm doing some tests in a dummy server and I can see that sometimes merge_task captures RuntimeError('Event loop is closed') when calling api (or, ultimately, the long-lived instance of httpx.AsyncClient) so I'd bet that the loop for httpx.AsyncClient is closed after some time and there's no issue with asgiref's async_to_sync. Am I correct? If so, the only solution is to instantiate httpx.AsyncClient on every request? I tried do call merge_task using the endpoint but it captured RuntimeError('Event loop is closed'). The expectation is to not raise any error related to async programming -
Pytest, get IntegrityError when inserting ForeignKey by id
I have such table structure class ParentModel(models.Model): symbol = models.CharField(max_length=255, primary_key=True) name = models.CharField(max_length=200) class ChildModel(models.Model): parent_instrument = models.ForeignKey( to=ParentModel, on_delete=models.SET_NULL, null=True, blank=True, ) instrument = models.ForeignKey( to=ParentModel, on_delete=models.SET_NULL, null=True, blank=True, ) Then I run my pytest with empty database, where I test such logic try: ChildModel.objects.update_or_create( parent_instrument_id=symbol1, instrument_id=symbol2, ) except IntegrityError: self._create_instrument(symbol1, symbol2) I don't get IntegrityError. ChildModel is just saved without existing ParentModel symbol. Is it possible to avoid such behaviour? -
How can I change the delimiters in .vue file?

How to Integrate GTM with Partytown in Django Template
I am trying to integrate my GTM tag using Django Template. Following is my current html snipped that is working perfectly fine without partytown integration. <head> <script> (function (w, d, s, l, i) { w[l] = w[l] || []; w[l].push({ 'gtm.start': new Date().getTime(), event: 'gtm.js' }); var f = d.getElementsByTagName(s)[0], j = d.createElement(s), dl = l != 'dataLayer' ?

Also note that I have integrated partytown library in my project so that is not a problem. No errors there just dont know how to integrate it. Thanks in advance -
Django site wide caching with vary on Cookie header caching per user response due to third party cookies
I am currently trying to set up the per-site-cache, it all seemed to work fine locally but once I moved it onto test servers with google analytics I noticed that it wasn't serving pages from the cache as expected. After a bit of digging I realised that this was due to another third party app that we are using (and need) that was accessing the session middleware, if the session middleware is accessed then Django will add 'Cookie' to the vary headers: # django/contrib/sessions/middleware.py if accessed: patch_vary_headers(response, ('Cookie',)) HTTP header: Vary: Cookie, Accept-Language The issue I have is that when Django is generating the cache key it is looking at all the cookies that are in the request, including third party ones (e.g. google analytics) which are nothing to do with Django and which do not impact on rendering the view. I don't want to monkey patch the third party Django app that we are using to stop is accessing the session. I could patch the vary headers to remove the vary on cookie header completely but I think that if the session middleware is setting the header then it is probably safer to leave it alone and just filter … -
Long running Django Celery task close DB connection
I have a Django Celery task that performs long-running operations and sometimes loses connection to the database (Postgres). the task looks like something like this: @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost I want to ensure the connection (but also be able to unit test this code). For example: @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): connection.connect() self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost This would work (because it always opens new connections) but the unit test throws the error that can't roll back on teardown. I am thinking about @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): try: self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost except Exception e: connection.connect() MyObject.objects.bulk_create(objs=batch) # retry this insert but is there a better way to handle this? -
Does nest js provide anything that runs after saving, updating or deleting, like how django signals provides?
I am running a project with nest js and prisma orm. Suppose I am creating a post record like following: // Query the database to create post ------------------------------------------------------- try { post = await this.prisma.post.create({ data: { uuid: uuidv4(), author: createPostDto.author, categoryId: postCategory.id, title: createPostDto.title, content: createPostDto.content, createdAt: new Date(), updatedAt: new Date(), } }) } catch (err) { this.logger.error(err); throw new InternalServerErrorException("Failed to create the post"); } After creating a record I want to run some perticular code. suppose I want to send notification to admins by calling sendNotification() method. But I don't want to call this method from inside an api. I know that django signals provide similar feature that can be used to run some part of code after creating, updating, or deleting a row. But I don't know what should be aprropeiate in the case of nest js. -
Django program gets stuck on get request, needs to be interrupted with Ctrl C to continue
I have tried everything I can possibly think of but I don't know what the solution is. I have a django application which running on my local network and receives requests from a react app. When the page loads tables (around 10 requests) the server seems to work quite well but randomly gets hung. When it gets hung it doesn't reach the view (the print statement doesnt run: def f(request): start_time = time.time() print('Received GET request')) and the moment I interrupt it a backlog of get requests like: Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> which print in one go and then all the remaing requests are filled.

My question is How real world game lobbies handle this problem ? Is there a way to Handle concurrent connections ? Any help is appreciated :) -

I do not know much of Javascript, and I think I am going wrong somewhere in the Javascript Function or something else entirely. What I need to do is render the "id_mapnubparam01" field only when value of "id_mapnubfunction" is 'GETDATA'. I've split the if condition into 2 just to be clear, the first if condition for the "p" tag works perfectly fine. However using the same if then else logic the "id_mapnubparam01" does not do anything. Any help is appreciated. Thanks. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Data</title> </head> <body> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {% for field in form %} <div class="fieldWrapper"> <label>{{ field.label_tag }}</label> {{ field }} </div> {% endfor %} <input type="submit" value="Submit"> </form> <p id="demo"></p> <script> function myFunction() { var x = document.getElementById("id_mapnubfunction").value; if (x != 'GETDATA') {document.getElementById("demo").innerHTML = ""; } else {document.getElementById("demo").innerHTML = "You selected: " + x; } if (x != 'GETDATA') {document.getElementById('id_mapnubparam01').hide(); } else {document.getElementById('id_mapnubparam01').show(); } } </script> </body> </html>
