Django ORM for custom python function
I have following two models class Membership(models.BaseModel): user = models.ForeignKey(User) package = models.ForeignKey(Package, on_delete=models.PROTECT, blank=True, null=True, related_name="package_membersips") benefit_end = models.DateField() benefit_start = models.DateField() class Package(models.BaseModel): name = models.CharField(max_length=40) description = models.CharField(max_length=200, null=True, blank=True) class PackageTier(BaseModel): package = models.ForeignKey(Package, on_delete=models.CASCADE, related_name='package_tiers') min_members = models.IntegerField() max_members = models.IntegerField() retail_price = models.DecimalField(max_digits=5, decimal_places=2) wholesale_price = models.DecimalField(max_digits=5, decimal_places=2) The wholesale_price and retail_price calculation consists of some logic, that is difficult to perform using ORM: def get_package_price(package_instance): count = package_instance.package_memberships.count() tier = package_instance.package_tiers.filter( min_members__lte=count + 1, max_members__gte=count + 1 ).first() if not tier: tier = package_instance.package_tiers.order_by('id').first() return tier.retail_price if tier else 0 def get_package_wholesale_price(package_instance): count = package_instance.package_memberships.count() tier = package_instance.package_tiers.filter( min_members__lte=count, max_members__gte=count ).first() if not tier: tier = package_instance.package_tiers.order_by('id').first() return tier.wholesale_price if tier else 0 These are business logic and I need to aggregate the result based on the year basis. # sample response: {"data": [ { "year": 2021, "commission": 1.0 }, { "year": 2022, "commission": 8.2 }, { "year": 2023, "commission": 11.0 }, ]} Is there any way that I can use get_package_price and get_package_wholesale_price inside Django ORM ? I used following ORM to get membership for each year: Membership.objects.all().annotate(year=ExtractYear('benefit_start')).values('year').order_by('year') The custom function need to be called in this ORM. -
Why is caching not improving the performance in my django view?
I am trying to improve performance of a view by caching a given linear algebra expression and its corresponding result. I am using memcached and pymemcache but for some reason theres no performance gain. Heres my view: @api_view(['POST']) @login_required(login_url='/api/login/') @csrf_exempt def compute_lalg_expression(request): form = LinearAlgebraExpForm(request.POST) if form.is_valid(): new_expr = form.save(commit=False) data_expr = form.cleaned_data data_expr = data_expr['exp'] exp_hash = hashlib.md5(data_expr.encode()).hexdigest() alg_exp = cache.get(exp_hash) if not alg_exp: parsed_exp = parser.parse(data_expr) eval_data = evaluate(parsed_exp) expr_model = LinearAlgebraExpression(exp=eval_data) expr_model.save() create_action(request.user, 'computed an expression', expr_model) serializer = LinearAlgebraExpSerializer(expr_model) cache.set(exp_hash, serializer.data) return Response(serializer.data) return Response(alg_exp) And here is the client I am testing it with. I am testing it by removing the lines associated with caching above so I am removing exp_hash, alg_exp and so on so I remove the if statement that checks whether alg_exp is true or false and i remove cache_set. Anyways heres my client import aiohttp import asyncio import time async def make_request(session): url = 'http://127.0.0.1:8000/api/compute/' payload = {'exp': exp + '*' + exp2} # Replace with your POST data async with session.post(url, data=payload, auth=aiohttp.BasicAuth('jobpink', 'hello123')) as response: return await response.text() async def main(): # Adjust these values as needed num_requests = 5000 # Number of requests to send concurrency = 10 … -

Django cors headers not working with POST requests
My stack is: axios for the javascript client, apache2 reverse proxy, gunicorn, django. I have setup the django-cors-headers plugin. I am able to perform GET requests to the django application.

Why is my Docx converter returning 'None'
I am new to web development and trying to create a language translation app in Django that translates uploaded documents. It relies on a series of interconversions between pdf and docx. When my code ouputs the translated document it cannot be opened. When I inspect the file type I saw it identified as XML and docx and it could be opened and read by MS Word when I changed the extension to docx(But it couldn't be read by any PDF readers). When I used my code python to analyze the file by printing the type and the contents of it I got NoneType and None. A working PDF of the file is found in mysite/mysite folder but the one output by my reConverter function that is sent to the browser is the problem file. I tried manually converting it using: wordObj = win32com.client.Dispatch('Word.Application') docObj = wordObj.Documents.Open(wordFilename) docObj.SaveAs(pdfFilename, FileFormat=wdFormatPDF) docObj.Close() wordObj.Quit() but got a CoInitialization error. My original So I've completely narrowed it down to the reConverter function returning a NoneType.

User Based Views
I am working on a project whereby I would like to generate a report which has the ability to have a drop down list of users, such that the data in the report changes depending upon the user being selected. I'm looking at this from an admin perspective. I know how to create such a view for request.user, but I'm not entirely sure how to create the functionality for a drop down list of users and then the output changes. Any thoughts as to how to do this? I do have an example of existing code I can provide to show what I am trying to achieve; however it won't necessarily answer my question. Best, Neil -

Django-Docker: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known
First-time docker-user: I recently added a cron job to my Django project and dockerized it. When I run docker-compose up --build, the system builds and runs the cron job, which exits with a code 137 (which is expected, since I'm running locally). When I try to run the cron job manually to troubleshoot methods of lowering the cron's CPU usage, I am met with: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known This error is odd to me, since everything is fine upon build, but it seems like the command no longer knows what the database is outside of the build even with the project running.

Assign model permissions of Model1 to a Model2 in django using django guardians
I am using Django Guardians in my project and it works fine so far, but there is some problem: I need to assign permissions from model1 to the instance of the model2. Real example: The shop has some contracts and the shop owner wants to assign his employees permission to change contract fields (e.g. field1). So we have 3 models now: Shop, Contract, and User, and each model has it's own defined permissions per field like: can_change_field1, ... All permissions that employee can have must be related to the Shop model because when a shop owner assign contract permissions to his employee (to change field1 in contract in shop1), it mustn't affect another shop (So user will not be able to change that field e.g. field1 in shop2,...). 1st solution can be: to create all permissions in shop model (for all models: Contract,...). But it seems kinda of messy to me. What do you think? Please, Can you suggest some nice solution to this problem? -

Django Admin Dropdown Filtering: Show Exam Class Related Students in Student Assign Field
I'm working on a school management system using Django, and I'm currently facing an issue with customizing the behavior of dropdown fields in the Django admin interface. In my application, I have models for managing exams, students, and student results. Each exam is assigned to a subject, which is associated with a specific class and section. When I'm creating a student result entry in the admin panel, I want to ensure that the student_assign field only displays students who are part of the same class as the exam subject. More specifically, when I select an ExamAssign in the admin form, I want the related student_assign dropdown field to dynamically filter and display only those students who are associated with the same class as the selected exam subject. If I Select Class 10 here I want only to show the related class students (not only the section) here. I've tried implementing this using a custom admin form and overriding the __init__ method, but I'm encountering issues with getting the related students based on the selected exam's subject. Could anyone guide me through the correct way to achieve this functionality? I'd greatly appreciate any help or advice on how to properly filter … -

Make Django DB Transaction Idempotent on an External Call
I'm using a Django DB with a Postgres backend. Each user has a "balance" associated with their DB object, which is their current funds in the system. They can cash out the balance via gift cards, which is done by sending a POST request to Amazon's API. I perform two operations when the cash out their balance: Update the DB to set their balance to 0 Send a POST request to the Amazon API to generate a gift card for their balance If only one of these operations happen, that's very bad, for obvious reasons. I know you can use Transactions to make sure multiple database operations happen atomically -- is there a way to do something similar with a DB operation and an external call like this? -
