Ingress health check failing on Django GKE Deployemnt
I am deploying a frontend (Nuxt) and a backend (Django) using GKE Autopilot. A CI/CD pipeline has been set up from github to GKE.

Custom Django Admin Page/View
Basically I'm trying to create a custom admin web page, like a custom a view. Ideally what I want is something where like once you log in to the admin page, there would be a link somewhere like under the list of models that would redirect you to this admin center. I have a somewhat working version currently, but I would like to have it redirect to a new URL like “ /admin/social/edit/ “ instead and not just render context into the template. I’ve done a ton of googling and I just keep coming across things like “custom admin actions” which is not per se what I’m looking to do. Any help is appreciated. Thank you. -

How can I set group permissions that filter pages according to their owners in Wagtail
I am working on a blog with Wagtail and would like to give users access to create their own content in the Wagtail admin. I would like users to be able to log into the Wagtail admin, but only have access to content that they have created themselves. I have tried to generate permissions by group, however there is no default option to limit content by author, so if I give add, edit and publish permissions, a user could edit content created by other users and could unpublish or even delete that content. I would like to know if there is a way to modify the queryset of pages that appear in the Wagtail admin for a specific user. I don't have much experience with Wagtail. So far I have seen some possible solutions but none have seemed viable or adequate. For example, there are some posts here where they propose to create a Parent page for each user, but then you would have to create a group for each user, which doesn't seem like an efficient way to do it. I appreciate any help or suggestions. Here I share some of the relevant code: class BlogIndexPage(Page): max_count = 1 … -

using mongodb with motor driver and django
i'm creating an App, using async driver(motor) for mongodb. I have a telegram bot app and django framework app. I want my telegram and web apps use same database. When i try to create User via integrated CreateView class, by default django uses it's standart auth processing and adds user to its default databases(sqlite, postgre etc.) But i'd like to use mongodb and use it asyncronous(as i understood djongo is syncronous driver) the ways I see to solve this: 1) separate users' auth data(to standart database) and other data, that'll be fetched and overwritten frequently(to mongo). 2) use standart view(e.g. TemplateView, FormView) and my own form, write MyOwnUserClass with hashing and all necessary methods. Shortly I want to use instruments of Django with mongodb, how can I reach that? Well don't know if this is needed here, a piece of my current code: forms.py: class RegisterUserForm(UserCreationForm): username = forms.CharField email = forms.EmailField password = forms.PasswordInput password_confirm = forms.PasswordInput telegram = forms.CharField(required=False) views.py: class Register(CreateView): template_name = 'AIsite/register.html' form_class = RegisterUserForm success_url = reverse_lazy('login-user') -

How to limit client IP of a Django app? (Through django and/or PaaS)
I am making a Django app and I wish to enhance the security as well as limit users by making sure only clients only from one IP (say a shared VPN) can access it. I plan to host the app on a PaaS like Digital Ocean App Platform or Heroku. How can I limit the client IP through: Django, to prevent other users from accessing the app, and The PaaS, so that potential attackers don't have access to the platform in the first place? (Hopefully some PaaS has this optiont) -

Heroku can't find styles.css
Trying to deploy a Django app to Heroku for the first time. When I view the app using Django, everything shows up correctly, but when I run it on Heroku, pieces of the UI are missing. I'm not too familiar with the frontend - this was a group project and I was working on backend - and my team isn't willing to help with deployment, so I'm unable to diagnose any frontend issues. Looking at the Heroku logs, I get this error "Not Found: /static/styles.css" - but there is a styles.css file under static. Does anyone know where the root problem might lie? Under settings.py I have specified this STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [os.path.join(BASE_DIR, 'staticfiles')] All functionalities work as expected, I think it has something to do with the base.html file - but this is just a stab in the dark. An example of what it's meant to look like, compared to what it looks like on Heroku. -

What would be a better solution for storing data in a Django model?
Could you please give me a piece of advice? Context: I have a Django project in which each user stores many different variables linked to his profile. I created a model called Snapshot, that has a foreign key of user. Single user can have multiple Snapshots linked to his User instance, but only the latest one (by its ID, pk) is editable. Any other ones might be used to revert to past setup only. Typical use case: User modifies his setup stored in his latest Snapshot using API endpoints. Each function that an endpoint call has to query the latest Snapshot owned by user that called the function. Then it modifies some of the variables in the Snapshot and saves it. Once everything's done user approves the setup and the Snapshot is being duplicated. Now the new instance becomes the latest. Question: Is it a good idea to query the latest Snapshot this many times in each function? Wouldn't it be a good idea to link the latest Snapshot one-to-one with User, so that it's always available as User.latest_snapshot? This latest_snapshot would be automatically re-linked to User once user approves setup, thus creating a new Snapshot. -

In the ideal case we would have a patient referred to as 'H6F4A' and the samples to be 'H6F4A-1', 'H6F4A-2', etc. (be labelled by a suffix of the sample number belonging to that patient). As a requirement we would need that if a sample is deleted that the sample numbering doesn't change for the suceeding samples (as the samples have physical barcodes printed onto them). As this is kind of hard to do (probably one would need a counter for every patient counting how many samples there are) we have opted to use the tissuesample pk as the suffix which is not really what we want as this is global and not per patient. Even if this new counter would not be a pk, combined with the hashed id of its parent e.g. sample 1 of patient 1 being 'H6F4A-1' it would need to be an injective mapping as staff will always refer to this … -
How to make on update record pass the signal in Django Model?
Hello I'm trying to make on update trigger in Django Model. Model.py class Item(models.Model): status_type = ( ('a','Active'), ('d','Deactive') ) code = models.CharField(max_length=100, null=True, blank=True, unique=True) name = models.CharField(max_length=100) price = models.DecimalField(max_digits=10, decimal_places=2) gsts = models.ForeignKey(Gst, on_delete=models.CASCADE) sgst = models.DecimalField(max_digits=10, decimal_places=2,null=True,blank=True) cgst = models.DecimalField(max_digits=10, decimal_places=2,null=True,blank=True) net_amount = models.DecimalField(max_digits=10, decimal_places=2,null=True,blank=True) status = models.CharField(max_length=1, choices=status_type, default = 'a') create_at = models.DateField(auto_now_add=True) update_at = models.DateField(auto_now=True) create_by = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.name def ItemGenerator(sender, instance, created, *args, **kwargs): if created: id = instance query = Item.objects.get(id = int(id.id)) #gst calculation gst_cal = query.price * query.gsts.gst/100 #net amount calculation net_amounts = query.price + gst_cal #item number generate temp_count = Item.objects.all().count() no = str('ITEM') + '/' +str(temp_count) query = Item.objects.filter(id = id.id).update(code = str(no), cgst = round(gst_cal/2), sgst=round(gst_cal/2), net_amount = round(net_amounts)) When I'm insert to the data post_save signal is call and my price and gst calculation save into data base but problem is that when I'm update the record post_save signal is not working
