Django Snippets/Updating Primary Key
I have a client that requested (after launch) to start their records at a very large number (3,000,000). The model itself has at least 10 relationships/reverse relationships all through FK, established with "on_delete=CASCADE". Originally I was working with this snippet: https://djangosnippets.org/snippets/10619/, which gave quite a few errors. After some formatting (removing %s formatting for easier to read f-string formatting), the script ran but gave the dreaded: Cannot delete or update a parent row: a foreign key constraint fails. I am looking at any sort of way to get the 100 or so records (and their respective relationships) to update accordingly. I have already updated the MYSQL database to start numbering from the last record + 3,000,000 so that any resulting scripts should not result in a collision keeping the PK restraints. I believe there used to be a way to do this via a simple model.objects.all().update(id=F('id')+3000000), but this also has failed in Django 4.2. Any help is appreciated. d -
htmx isn't call in meta widgets
I'm trying to validate a field in a crispy form in Django using htmx: class Foo( forms.ModelForm ): id = forms.CharField( label='Id', disabled="true") # WORKING local_amount = forms.DecimalField( label='Local Amount', required=True, max_digits=10, decimal_places=2, widget=forms.TextInput(attrs={ 'type': 'number', # Use 'number' type for numeric input 'hx-get': reverse_lazy('check_amount'), 'hx-trigger': 'change', # Trigger the request when the value changes }) ) class Meta: model = Cost_schedule_org_unit fields = ['id','cost_schedule', 'local_amount',.....] # NOT WORKING IN THIS WAY widgets = { 'local_amount' : forms.TextInput(attrs={ 'type': 'number', # Use 'number' type for numeric input 'hx-get': reverse_lazy('check_amount'), 'hx-trigger': 'change', }) } The htmx call is working in the first way but not on the second way? -
Authenticating a user's identity using date of birth
I have a question regarding my implementation of an authentication system based on date of birth. I am using Django, but I think this question can be generalized. The use case is that the server already knows two things about the user, without them having made an account: a code uniquely assigned to them, and their date of birth. I want to use the combination of these things to authenticate their identity and display sensitive information that belongs specifically to them. I am trying to understand the best way to do this. Since the user will not be using this website very often, I do not want them to create an account. Currently my thought process is: user opens webpage with the unique token in the url and enters date of birth. Server validates the token and date of birth and informs the client. On subsequent requests to the server, include date of birth as a header or data field, and perform the same validation on the back-end. Would this work? Are there superior implementation patterns? -

Oracle "ORA-00942: table or view does not exist" using Django with multiple databases/schemas
I recently had to change up my Django back end to accommodate a "restricted database user". Instead of querying the database using the database admin user that is responsible for making/migrating migrations, a user with SELECT, INSERT, UPDATE, and DELETE on only the necessary tables was created. I set up the databases in settings.py like so: DATABASES = { 'default': {'ENGINE': 'django.db.backends.oracle', 'NAME': 'dbname', 'USER': 'restricted', 'PASSWORD': '*********', 'HOST': '*******************', 'PORT': '****', }, 'migrations': { 'ENGINE': 'django.db.backends.oracle', 'NAME': 'dbname', 'USER': 'admin', 'PASSWORD': '*********', 'HOST': '*********************', 'PORT': '****', }, } With the databases set up like this, any queries that are executed from your views go through the "default" restricted user, and the admin user is only there for migrations. To migrate, you would run - python manage.py makemigrations (this command does not change as it does not care about the database user) and then python manage.py migrate --database=migrations After doing this, none of my views worked, and I discovered the reason why. The next step that I had to do was to change all of the db_table values in my models.py to match the schema of the new user. So any db_table values went from this db_table = 'items' to … -
Django Middleware check if page contents was cached
I have a middleware that manages and denies access based on trial info stored in the user model. One aspect of it is that it increments the request count by 1 each time. But also on a lot of endpoints, we have the results returned cached using method_decorator. Is there a way to see if the page they're accessing is cached or not, so that I can avoid incrementing their request count if they would be using a cached result? -
How to add particular css classes to the checkboxes generated by a django MultipleChoiceField?

The goal is to be able to target them in javascript to make grouped selections. How can I access each checkbox individually, in python, in order to add a class? -
How to design a dynamic gamification microservice in django
I want to implement a gamification microservice with Django that works alongside other microservices. In this microservice, I want to have points, ranks, coins, badges and credit cards for each user. Points: A number that is earned based on the user’s activity and this activity is not limited to purchase operations and can be earned by performing any kind of activity. Uses of points include increasing rank, buying discount codes and increasing lottery chances. Rank: For example, you can have 5 ranks for users and rank them based on the total points they have earned so far. The ranks can be named from “Newcomer” to “Professional” level. Special benefits are provided for each rank, which may include discounts, various notifications, coefficient in getting rewards, etc. Coins: Only earned for financial transactions. The higher the transaction amount, the more coins the user earns. You can get benefits other than discount codes through coins. Badge: They are awarded to a person for repeating a specific activity. Having badges gives the user special advantages. Credit card: A type of credit for in-app and out-of-app purchases. For example, you can buy a credit card for a specific product with a credit of $100 for … -
Nearest int query inside a json field object
I have a gigantic db with a json field object storing around 30 sub-objects per entry. Looks like that: { "field1": {"someOther": "stuffInside", [...]}, "field2": {"someOther": "stuffInside", [...]}, [...] } All these fields contain one field with a bigint. My objective is to be able to match the closest entry from a given int, for that purpose I made a function that does exactly that: def get_closest_match( field: str, match: int, model: django.db.models.Model, return_all_match: bool = False, sub_filter: dict or None = None, ): log.debug(f"Finding nearest in {model.__name__} with {field} {match}") result = model.objects.annotate(abs_diff=Func(F(field) - match, function='ABS')) if sub_filter: result = result.filter(**sub_filter) result = result.order_by('abs_diff') if not return_all_match: return result.first() return result While this function works great for int fields, I wasn't able to make it compatible with jsonfields, is there a way to make my function work with an int inside a jsonfield ? My first idea was to make a separate table storing only those bigints so I could use my method, which in fact works, but as mentionned above, each entry has around 30 objects and I have millions of entries so performance wise it is not very optimal (It also make data duplication which is not … -

Where is the parameter 'request' used in view.py in django
A newbie in Django web development. I've got a tiny but puzzling question about request / response in views.py. I self-learn Django online and here comes the http request / response section. The code is as follows: #from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("<h1>123</h1>") I understand that the index page is requested and django creates a response which shows 123 in the index page. My questions are: with the request as the parameter of the function, isn't it used in the body of the function, just like def math(x): return x+1? Also, why does render become redundant in this trunk of code, where it should be used to produce output? Thanks for answering. -
Using django select_for_update for not updating but creating new records
I am using Django==2.2 and trying to create some new records for an object in django only if an upper limit is not reached. I was checking with unused_count = Account.objects.filter(field1__isnull=True, field2__isnull=True).count() vacancies = UPPER_LIMIT - unused_count if vacancies > 0: *create (vacancies) new accounts here* however we faced a case where this is not being respected and double the max limit accounts got created, and most probably seems like a concurrency issue. Just wanted to confirm that using unused_count = Account.objects.select_for_update().filter(field1__isnull=True, field2__isnull=True).count() will suffice and prevent this issue or not? The whole method is wrapped in @transaction.atomic -

How to Customize the Error Response in Django

So I have a Django blog and I am trying to implement a threaded comment functionality using FETCH API to avoid a page refresh each time a comment is submitted. Also, I intend to limit the number of comments shown first to just 10 with a "load more comments" button at the bottom that when clicked would reveal the next 10 comments, and so on until there is no more comment to be shown at which point the "load more comments" button disappears. You see, I successfully implemented this feature with FETCH API for only single parent comments. But I am trying to take my blog further by adding a threaded comment, or rather, to make it possible for parent comments to have child comments. However, I can't seem to successfully implement the above functionalities asynchronously. Only after reloading the page do the parent comments and child comments show on the page, but I want the comments to show immediately after hitting the comment submit button. I believe the problem is with my Javascript … -
How to make text remain on page even after user exits and opens again?
Using js,it is possible to make text remain on screen when user submits the text, but I want that it remains even after user exits or lets say opens the website on a different device. I think databases would be involved. Can we use Django for this purpose? I am trying to make a website like a common notepad type thing. Anyone who opens the site can add text and leave and it stays there until he himself or any other person removes the number. How should I proceed with this idea?
