Why single html <p> tag is being spilt into two <p> tags with a <br> tag between them?
Below is my template html tag ( django): <p class="card-text cfs-9 cfc-grey">{{i.post|safe|truncatechars:100}}</p> This tag render totally fine on local server, but on production server, this single <p> tag is being split into two <p> tags and an extra <br> tag appear out on nowhere between them. I think the issue is with 'truncatechars' but i could not figure out. Below is view source code from both local and production server. Local Server view page source: <p class="card-text cfs-9 cfc-grey">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the…</p> Production server view page source: <p class="card-text cfs-9 cfc-grey"><br><p>In this post I'll be demonstrating how we can deploy Django website on…</p> I tried {{i.post|truncatechars:10|safe}} instead of {{i.post|safe|truncatechars:100}} but the problem remains.Tried using 'truncatewords' but still same problem. -
Specifying a relation through multiple shared foreign keys
Let's say we have 4 models, lets call them Alpha, Beta, Gamma, and Delta and the first two are something like: class Alpha(models.Model): gamma = models.ForeignKey(Gamma, on_delete=models.RESTRICT) delta = models.ForeignKey(Delta, on_delete=models.RESTRICT) text = models.CharField(max_length=1024) class Meta: constraints = [ models.UniqueConstraint(fields=['gamma_id', 'delta_id']) ] class Beta(models.Model): gamma = models.ForeignKey(Gamma, on_delete=models.RESTRICT) delta = models.ForeignKey(Delta, on_delete=models.RESTRICT) value = models.IntegerField() As you can see the two foreign keys can be used to associate any number of rows from Beta with one row from Alpha. There is essentially a one to many relationship between Beta and Alpha. For various reasons it is not feasible to replace the two foreign keys in Beta with a foreign key to Alpha. Is there a way to define a relationship on Alpha that returns all the rows from Beta that have the same gamma_id and delta_id -

Passing a list of senders to the sender parameter of @receiver decorator
So at the moment, I'm working on my Django project and I have a signal receiver function that looks like this: @receiver(pre_save, sender=Task, dispatch_uid='core.models.task_handler_pre_1') @receiver(pre_save, sender=TaskHistory, dispatch_uid='core.models.task_handler_pre_2') @receiver(pre_save, sender=TaskUser, dispatch_uid='core.models.task_handler_pre_3') def task_handler_pre(sender, instance, **kwargs): # do some stuff In an attempt to make the code look cleaner, I was wondering whether would it be possible to do something like this: @receiver(pre_save, sender=[Task, TaskHistory, TaskUser], dispatch_uid='core.models.task_handler_pre') def task_handler_pre(sender, instance, **kwargs): # do some stuff i.e. Does the sender parameter accepts a list of senders as a valid argument ? If not, then does the value of the dispatch_uid parameter within the @receiver decorator, have to be different for each individual sender, or can it be the same i.e. As mentioned previously, my receiver function looks like this at the moment: @receiver(pre_save, sender=Task, dispatch_uid='core.models.task_handler_pre_1') @receiver(pre_save, sender=TaskHistory, dispatch_uid='core.models.task_handler_pre_2') @receiver(pre_save, sender=TaskUser, dispatch_uid='core.models.task_handler_pre_3') def task_handler_pre(sender, instance, **kwargs): # do some stuff What difference would it make if I make the following change: @receiver(pre_save, sender=Task, dispatch_uid='core.models.task_handler_pre') @receiver(pre_save, sender=TaskHistory, dispatch_uid='core.models.task_handler_pre') @receiver(pre_save, sender=TaskUser, dispatch_uid='core.models.task_handler_pre') def task_handler_pre(sender, instance, **kwargs): # do some stuff i.e. make the value of the dispatch_uid parameter the same ( core.models.task_handler_pre ) for each individual sender.

How to route nginx pages to different pages?
Hello I have django app let's suppose my site uri is example.com now i want to route my admin dashboard to another port like if users types abc.example.com it automatically routes to main page of my app but i want to have abc.example.com:445/admin/* is it possible the solution i tried was server { listen 443 ssl; server_name abc.example.com; client_max_body_size 500M; ssl_certificate /etc/nginx/my.crt; ssl_certificate_key /etc/nginx/server.key; location / { proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $http_host; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://localhost:3001; } } server{ listen 445 ssl; server_name abc.example.com; client_max_body_size 500M; ssl_certificate /etc/nginx/my.crt; ssl_certificate_key /etc/nginx/server.key; location /admin { proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $http_host; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://localhost:3001; } } server { listen 80; server_name abc.example.com; return 301 https://$host$request_uri; } But this itself routes to port 443 and /admin page is also available there so how to avoid this any possible solutions. -

Django/DRF Pagination using paginate_queryset doesn't return key, value but only keys in result
I've added pagination handling on one of my views using PageNumberPagination from DRF, using the paginate_queryset method works only after converting the result dict to a tuple, it's structure is like the following: { "key": {"other": "dict inside"}, "key2": {"other": "dict inside"}, "key3": {"other": "dict inside"}, } Pretty simple struct, the problem is that the result does return the correct data, but only their keys, I would like the result data to be key, value as the above structure instead of just keys. Is there an easy way of doing that? For reference I also already override PageNumberPagination with a custom class like this: class CustomPagination(PageNumberPagination): def get_paginated_response(self, data): return Response({ 'controller': { 'count': self.page.paginator.count, 'previous': self.get_previous_link(), 'next': self.get_next_link(), }, 'results': data }) And in my view to paginate: class ApiView(APIView, CustomPagination): page_size = 10 def get(self, request): # [...] pagination = self.paginate_queryset(tuple(result), request, view=self) return self.get_paginated_response(pagination) Where result is the original dict mentionned above converted to a tuple. -
Django - Link to download bringing me a past file
I have a regular Django project working fine for year and links for many download Microsoft Excel templates. The thing is I've change one of them, and when I click to download it, it downloads me the older spreadsheet (I've deleted it on my server). But if I access on an incognito browser, it downloads me the newest version. What should I do to solve this, is it something related to time expiration of cookies or something like this?

Dynamically choices for microservices in django rest (best practices)
I have a microservice A which asks microservice B about what type of products can microservice A receive as it's choices for some CharField, for example, "Type". And I have some options, where to make the actual request to microservice B: 1)Model level (CharField(choices=TYPES)) 2)Serializers level 3)View level of the microservice A. So, when I'm adding some new type to microservice B "Type" model instance, I have to restart microservice A to receive this new option to create. But as it comes to the "list" ViewSet action, I can receive new types dynamically by just refreshing this page in browser, because of GET request So the question is: how to build this kind of connection between two microservices to avoid restarting the microservice A server to receive new options. I'll be glad to get some best practices. P.S. I heard about brokers, but at start level, I'm trying to get the actual mechanism of how it all works. After that I can build up comfortness, reliability and other features that comes with brokers -
Django: Alternate input forms for models in admin?
I'm basically asking if there's an equivalent to adding data kinda like how you'd create a new instance of a class using a classmethod instead of using init. My example is a publication input form - you can either add the data manually, or you can enter a key code (a DOI in this case), make a request to a central database, which will pull the rest of the data for you. Outside of Django, I'd implement it this way: from datetime import date class Publication: title: str = "" date: date = date.today() url: str = "" doi: str = "" publication_name: str = "" authors: list[str] = [] @classmethod def add_publication_manually(cls, title, pub_date, url, pub_name, authors, optional_doi): ob = cls.__new__(cls) ob.date = pub_date ob.title = title ob.url = url ob.publication_name = pub_name ob.authors = authors ob.doi = optional_doi return ob @classmethod def add_publication_from_crossref(cls, doi): import requests ob = cls.__new__(cls) # parse output from requests return ob if __name__ == "__main__": pub_list = [] pub = Publication.add_publication_manually("...") pub_list.append(pub) pub_doi = Publication.add_publication_from_crossref("doi") pub_list.append(pub_doi) I have a similar Django model set up, and I can add entries to the database using the "manual" method in the admin, but now I want … -
How to do model data validation in django

I save the category rights of the company that registered the product to CompanyRights. The company shows data from this table for product Categories while registering products. When I try to save a product: Cannot assign "3": "Products.cat" must be a "CompanyRights" instance. zeq, thanks -
403 Forbidden in Xcode Simulator but works fine with Xcode Canvas Preview
I'm wrote a Login page with SwiftUI, and a backend with Django(both running in my laptop) the login api works fine no matter using Postman or in Xcode Canvas Preview but when I run the Xcode Project with Simulator, the Login func would fail the backend returns 403 forbidden Funny thing is, it works fine until yesterday, and I didn't change the code, just suddenly it won't work in the simulator Can anyone tell me what's going on here? and how can I fix it? Thanks! I tried to disable the csrf middleware in Django setting.py, and it didn't work
