Preventing certain values adding to Django model
I'm trying to put a restriction on my Django model. I have a user model and then a model which allows one user to "follow" another. I want to put a restriction so the user cannot follow themselves. It's not really working at all but I'm sort of stuck what to do. When I try to add a new object. It will let me alter an existing entry but if I try to create a new one I get the error: Follower: Follower object (None)>" needs to have a value for field "id" before this many-to-many relationship can be used. It's like I have to save it somehow before I check for the items but I'm not sure how to go about it. Models class User(AbstractUser): pass class Follower(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE, related_name="followers", unique=True) follows = models.ManyToManyField(User,blank=True,related_name="follows") # Prevent User from following themselves def save(self, *args, **kwargs): if self.follows.contains(self.user): return else: super().save(*args, **kwargs) I've tried variations of the if statement and I've tried using a for loop to go through the ManytoMany field but I can see the object doesn't exist yet -
Get n value with n parameter with Django Queryset
this is my first question. If my question is not clear, let me know :) So I learn Django (learning by doing) for 4 Months in my project. I have one table name material, which is the table contains material name and price. Here I will describe my table: id materialName price 1 Not Required 0 2 Material 1 123 3 Material 2 456 4 Material 3 900 I want to calculate the total material price by getting the price from the table. It looks ok if I only want to get 1 price only. But, I need to get 4 values of prices from what the user wants in input. Let's say the user chooses Material 3, Material 2, Not Required and Not Required. So there is 4 material price. Then, I use a queryset like this: x = rawmaterial.objects.filter(Q(materialName = 'Material 3') | Q(materialName = 'Material 2') | Q(materialName = 'Not Required') | Q(materialName = 'Not Required')).values_list('price',flat=True) but the result is (900, 456, 0) not like (900, 456, 0, 0). I have been trying with SQL query using OR, is there any possibility to get 4 values? Thank you :) -

"invalid literal for int() with base 10:" error while changing DateTimeField to DateField in models.py | Django
I want to show how many posts are being made each day so i wrote this code: class ServerInsightsView(View): def get(self, request, server_tag): server = Server.objects.get(tag=server_tag) post_daily_count =server.posts.all().values('created').annotate(dailycount=Count('created')).order_by() #to get the number of posts each day depending on the DateTimeField return render(request, 'servers/insights.html', {'server':server, 'post_daily_count': post_daily_count}) This code is working but since created is a DateTimeField it groups the data depending on both date and time so for example (2022, 11, 15, 16, 24, 10, 577648) and (2022, 11, 15, 16, 40, 39, 224605) are in the same day but in different Time. so in order to fix this i've changed DateTimeField to DateField: Here is the models.py: class Post(models.Model): title = models.CharField(max_length=200) text = models.TextField(null=True, blank=True) saved = models.ManyToManyField(User, blank=True, related_name='saves') upvotes = models.ManyToManyField(User, blank=True, related_name='upvotes') downvotes = models.ManyToManyField(User, blank=True, related_name='downvotes') votes_count = models.IntegerField(default=0) server = models.ForeignKey(Server, on_delete=models.CASCADE, related_name='posts') creator = models.ForeignKey(User , on_delete=models.CASCADE, related_name='posts', null=True) created = models.DateField(auto_now_add=True) #was DateTimeField updated = models.DateField(auto_now=True) #was DateTimeField and now i get this error after this change: invalid literal for int() with base 10: b'15 16:24:10.577648' -
DJango displaying incorrect view

Multiple small API call vs single API call in Django Rest Framework

Handling notification Redirects to mobile apps and the frontend with Django Rest Framework
My project is in Django rest framework. It have web with react as well as android and ios. I am using Firebase push notification for notification purpose. Since I have to show my notification in app also, I have stored the notification in database and the notification database is as below: class Notification(models.Model): """ model to manage all notification """ receiver = models.UUIDField(max_length=255) title = models.CharField(max_length=255) body = models.TextField(blank=True, null=True) type = models.CharField(max_length=255) # order_type, registration_type is_read = models.BooleanField(default=False) redirect_url = models.CharField(max_length=255) Now the main problem I am facing is setting a redirect url for every notification. I want to redirect to specific page for different type of notification. For example for order_type notification i want to redirect user to order page, for comment_type notification I want to redirect user to comment page. How can I do that since i cannot just simply redirect to html url since there is react app, ios app as well as android app. I did not find much resource regarding this. Any help will be very much appreciated. Thanks. -

django postgres different values
Hi Django + Postgresql While studying aware datetime, I had a question and asked a question. Postgresql document For timestamp with time zone, the internally stored value is always in UTC (Universal Coordinated Time, traditionally known as Greenwich Mean Time, GMT). An input value that has an explicit time zone specified is converted to UTC using the appropriate offset for that time zone. If no time zone is stated in the input string, then it is assumed to be in the time zone indicated by the system's TimeZone parameter, and is converted to UTC using the offset for the timezone zone. Are you changing only the output differently according to the timezone setting value? (internally stored value is UTC ?) SET TIME ZONE 'KST' (Asia/Seoul +9) Why is the same query but different values?

Django logging missing while testing through the interactive shell
We added the below to show the SQL queries on the console. And, as a proof of concept, we are following the online tutorial to build a testing project. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', }, }, 'loggers': { 'django.db.backends': { 'level': 'DEBUG', 'handlers': ['console'], } }, } At the step of "Explore the free admin functionality", for example, the console SQL logging works as exacted. So, when clicking on the button, we see sample SQL logs like attached below. However, when using the interactive shell through the command python manage.py shell, and calling python commands like Choice.objects.filter(question__pub_date__year=current_year), we did not see any SQL log. We wonder if we missed anything for the backend logging on the interactive shell. We are testing with Django v3.1.4 and Python v3.7.6. Just let us know if you need more details.

I'm trying to call the property protocolo on a new imagefield's upload_to argument What I'm trying to accomplish is to have the saved images use a custom filename. class biopsia(models.Model): paciente = models.CharField(max_length=50) creado = models.DateTimeField(auto_now_add=True) foto = models.ImageField(upload_to=f'fotos_biopsias/%Y/{*protocolo*}', blank=True) def __str__(self): return str(self.protocolo) @property def protocolo(self): return 'BIO' + str(self.creado.year) + '-' + str(biopsia._base_manager.filter( creado__year=self.creado.year, creado__lt=self.creado ).count() + 1) File "C:\Users\LBM\Documents\virtualenviorements\clinico\biopsia\models.py", line 30, in biopsia foto = models.ImageField(upload_to=f'fotos_biopsias/%Y/{protocolo}', blank=True) NameError: name 'protocolo' is not defined* I've tried defining an outside method for upload_to but still I cannot use it inside my class -
How to skip if empty item in column in Django DB
I;m new to learning Django and ran into a small issue: I'm working on a product display page where some products are in a subcategory. I want to be able to display this subcategory when needed but I do not want it to show up when unused. Right now it will show up on my page as 'NONE' which I do not want. How do I fix this? My model looks like this: class Category(models.Model): category_name = models.CharField(max_length=200) sub_category = models.CharField(max_length=200,blank=True,null=True) On my webpage I use the {{category}} in a for loop to display the different categories. Unfortunately is shows 'NONE' when there is no subcategory. -

How to implement a user customizable and personalized dashboard with django
I've created a django website with user accounts and a database containing data and I would like each user to be able to create their own personalized dashboard to view only the data that they care about. How can this be implemented where each dashboard is connected to the specific user that created it? My question is a little vague because I don't know how to implement a feature that is created by a user, is viewable only by that user, and is persistent. Any help or guidance would be much appreciated! I haven't tried anything yet because I don't know how to get started. Online search results are things like creating a custom admin dashboard or a dashboard that is shared across all users, which is not what I'm looking for. -
Problem with redirecting to login page after successful authorization in django-microsoft-auth
I am using django-microsoft-auth to log in with Microsoft account. The problem I am facing is that I want to use it in my login.html and I've managed to add this button to my html, however it redirects me to admin page. My URL that I added in Azure is default one: https://<mydomain_name>.com/microsoft/auth-callback/ I found this solution on Stackoverflow but it requires changing URL on Azure AD. Is there any other way to change reditect from /admin to /home other than changing URL in Azure AD? I was thinking if I could change it somehow directly in library. -
