Post a JSON object on conditional input -- Django Restframework
Iam working on Django Restframework. I want to POST into an API to create an object. The problem is the condition I want to make, is itself in the POST data. For example, I have 5 fields: Name Lastname Email is_member membership_id I want to create a membership_id, if the user sends "is_member== True" while data posts. Problem: The data does get posted but the "membership_id" is blank. And no errors received. I could conclude that the reason is the "if/else" condition is triggered before all the fields are set. I tried to give the "if/else" condition when the function starts Inside the object which save the entry ie user_object. But nothing works Iam until here def create_user(request): if request.method == "POST": firstname = request.POST.get('firstname') lastname = request.POST.get('lastname') email = request.POST.get('email') is_member = request.POST.get('is_member') # default is = False category = request.POST.get('category') timestamp = int(datetime.now(tz=timezone.utc).timestamp()*1000) if is_member == True: membership_id = hashString(str(timestamp)) else: membership_id = "" try: user_object = MasterUser( firstname = firstname, lastname = lastname, email = email, is_member = is_member, membership_id = membership_id ) user_object.save() return HttpResponse('User successfully created') Is it possible or do I have to look out for some different apporach. Any ideas are welcomed! Thanks. -
Test failed for Date of Birth
I am a beginner in python-django coding. Currently I'm at the challenge part of https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Testing. My tests are going well except for def test_form_date_of_death_initially_set_to_expected_date(self). The error is AssertionError: datetime.date(1900, 1, 1) != datetime.date(2020, 6, 11) From what I understand the 1900,1,1 is the date that return to me after the function is done checking. But the problem is I have no idea how this date is coming out. I check thru my files and I cant see any codes setting it as 1900, 1, 1. So is this a default date if it is not set? If it is default by nature, how come i set test author date of death, it is still coming out 1900, 1, 1. Appreciate if anyone could help me.

trying to override allauth templates on a Django 3.2 app recognized in python 3.9

Design decision for deleting Django fields
I have a preexisting Postgres Database connected with the Django app. I want to delete a field in one of my Django models. I have 2 ways to do this: Manually delete the field from the auto generated files created during the previous migrations which django created -> Drop the column manually in the preexisting database -> Run migration again with the new migrations. Run makemigrations again which will cause django to create another migration file to drop the aforesaid field -> Migrate the preexisting database with the new migrations. Could anyone advice me what is the best practice to remove the field? Cheers, Fellow StackOverflower -
How to reposition form button in a Django template
I have a Django template that renders a form. The code is: {% block body %} <h3> Create Listing </h3> <table> <form action="{%url 'create' %}" method="POST"> {% csrf_token %} {{ form.as_table }} <input type="submit" value="Create Listing" class="btn btn-primary"> </form> </table> {% endblock %} Note: I'm using <table> to left justify the input boxes (otherwise the form looks messy on the screen). The blue "Create Listing" button is currently appearing above the input boxes. How do I move this button such that it's positioned below the input boxes? Thanks in advance! -

Problems with accessing a Model in the Admin website
I have created Profile model, which works fine in the admin website in Django, obviously, I try creating a very complex model but I keep getting error, anyway decided to streamline the process and I created a very simple model. models.py from django.db import models from django.conf import settings #from django_countries.fields import CountryField #from phone_field import PhoneField class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) email = models.EmailField(blank=True,null=True) role = models.TextField(blank=True) location = models.TextField(blank=True) photo = models.ImageField(upload_to='users/%Y/%m/%d', blank=True) def __str__(self): return f'Profile for user {self.user.username}' class Client(models.Model): firstname = models.CharField(blank=True, max_length=30) def __str__(self): return f'{self.firstname}' I ran python manage.py makemigrations and python manage.py migrate and the code works fine, I have also ensured that all previous migrations are deleted, so I successfully created a 0001_initial.py file in migrations.

Use django-compressor on form assets (media) in Django
According to the Django Doc on Form Assets. You can add static files (.css and .js) to your forms and widgets via the Media meta-class. However, I am trying to add .scss and .ts files instead. Those files would obviously be compressed by django-compressor. Everything is working fine with the normal static files in *project*/static/style/stylesheet.scss and in my apps' static directories, but how would I compress the files specified in the Media class ? I don't know if that's possible using django-compressor or if there is another way to achieve what I am trying to do. I could not find any documentation on this problem on the django-compressor doc. I tried to directly add the .scss file directly in the Media meta-class as such: class Media: css = {'all': ('accounts/style/accounts.scss',)} However, django tells me that the stylesheet is not of type text/css. That would mean that overriding the media system for this would be an option to render with text/scss instead and try to compress the file... Nonetheless, that approach seems a bit overkill. I would appreciate any help! -
Testing DRF GenericViewSet with parameters in url_path
I'm trying to test DRF endpoint with unittest.

Can you help me find out why my view can't parse parameters in the URL? Or any advice on how can I rewrite my test to successfully test my code. -

Running a Django REST-API on AWS - apache server does nothing
I have built a functional API with the django rest_framework, but as the runserver command is not suitable for production I am trying to get the AWS Apache to run the server as documented all over the place (e.g. : https://aws.amazon.com/getting-started/hands-on/deploy-python-application/ , https://dzone.com/articles/deploy-django-application , etc etc). Essentially, it's an image translation application that takes an image via a POST request and returns a modified image in the Response. Fairly simple, just one major endpoint. When I start or restart apache after running through all those configuration steps, i get a response saying "Restarted Apache" as expected. However, nothing is accessible! I can't run a POST command as I could with built-in server ./manage.py runserver 0.0.0.0:8000 So what's going on here? When I run with the built-in django server there are several parts of the start-up process that I can see and I get responses as expected, but with Apache? Nothing. -
CORS fetch issue HeaderDisallowedByPreflightResponse
I have an app running locally (Django app serving a React frontend, localhost:5000) and I have an external Django service on localhost:8888. Both work fine separately. The app needs to perform a GET to the service, but fails with: CORS error: HeaderDisallowedByPreflightResponse. The OPTIONS goes through OK, but this one fails. If I try performing the same request through Postman, it works fine. I've tried many header versions in my fetch, and this is what I ended up with, still not working: fetch(`${baseUrl}/programs`, { method: 'GET', mode: 'cors', headers: { 'X-API-Key': 'testing', 'Access-Control-Request-Method': 'GET', 'Access-Control-Allow-Origin': 'localhost:5000', // tried "*", as well 'Access-Control-Expose-Headers': 'X-API-Key, Content-Type, Access-Control-Request-Method, Access-Control-Allow-Origin', 'Access-Control-Allow-Methods': 'OPTIONS, GET, POST', 'Access-Control-Allow-Headers': 'X-API-Key, Content-Type, Access-Control-Request-Method, Access-Control-Allow-Origin', 'Content-Type': 'text/plain', 'Access-Control-Allow-Credentials': true, }, }).then((re) => { console.log(re); }) .catch(err => console.log(err)); Initially I started with just method, mode and headers X-API-Key, Access-Control-Allow-Origin and worked my way up from there. The external Django service has installed django-cors-headers and allowed all origins in the settings file so I'm not sure if this is the service's issue or frontend's. Any ideas what to try? -
Python Django Post Queue
Hi I have a Django Project. In my project, I want to queue all incoming post requests and show the sequence number. First in, first out. How can I go about this? Because I have created a project where many people can submit requests at the same time. When I receive a request like this at the same time, the server may crash or delays may occur.For this, I thought about queuing and giving sequence numbers to users, but I couldn't find much source about it. For example, 10 requests came all of a sudden, the server calls the functions on the backend and the sequence number 10 appears.
