How to test my business logic using Django and DRF without creating additional models that are used as references
I want to make bug-less code. I do the registration for applicants and application form that is divided by 3 blocks - personal data, application statement and admission documents. For each step there are additional requirements, for example if applicant didn't fill up personal info questionnaire the status of his application should "Without personal data" else "Awaits verification", on registration if applicant graduated school and wants to apply to Bachelor degree I have to check if there are admission campaign with bachelor preparation level and registration opened from 1 June til 1 July. If applicant applies earlier or later that period of time etc. The application forms are big and there should be some pre-populated data that applications refer to. This is how my test module looks like: import json import datetime as dt from rest_framework.test import APITestCase from organizations.models import Organization from portal_users.models import PhoneType from .models import * class ApplicantTestCase(APITestCase): # OBJ_RANGE - how many objects (records) to create (store at test DB) OBJ_RANGE = range(1, 7) # some refs must have dates and periods today = f'{dt.date.today()}' period = f'{dt.date.today() + dt.timedelta(days=365)}' def setup_refs(self): # Setting up reference models for questionnaire and application # in create_or_update there … -

How can i run Django channels on production?
I deployed a simple Django app to a VPS, here is my environment: virtualenv gunicorn nginx systemd Everything works perfectly, i can see my template loading. I also added a small Django Channels feature, but that part doesn't work; so while i can use it on WSGI without any problem, if i try to reach a Consumer, i will get an error. So my question is: how can i run Channels too in production? Here is what i currently did: /etc/nginx/sites-available/myproject server { listen 80; server_name 54.39.20.155; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /WaitingRoomVenv/WaitingRoom/WaitingRoom/static; } location / { include proxy_params; proxy_pass http://unix:/WaitingRoomVenv/WaitingRoomEnv.sock; } } /etc/systemd/system/gunicorn.service [Unit] Description=gunicorn daemon After=network.target [Service] User=root Group=www-data WorkingDirectory=/WaitingRoomVenv/WaitingRoom ExecStart=/WaitingRoomVenv/WaitingRoomEnv/bin/gunicorn --access-logfile - --workers 3 --bind unix:/WaitingRoomVenv/WaitingRoomEnv.sock WR.wsgi:application [Install] WantedBy=multi-user.target To start gunicorn: sudo systemctl start gunicorn To start nginx: sudo systemctl restart nginx -
Add argument to all views without having to edit them all to include variable in Django
What I need I'm developing a Pull Notification System to an existing Django Project. With there begin over 100+ views I'm looking to find a way to incorporate a argument(notification queryset) into all the views, as this is rendered to my base.html which I can do by passing it into a view's arguments dictionary. Problem I want to do this without editing all of the views as this would take a long time and would be required for all future views to include this variable. What I've tried Creating a template filter and pass in request.user as variable to return notification for that user. This works, however when the user selects a 'New' notification I want to send a signal back to the server to both redirect them to the notification link and change the status of viewed to 'True' (POST or AJAX). Which would required that specific view to know how to handle that particular request. What I've considered • Editing the very core 'View' in Django. I've tried my best to explain the issue, but if further info is required feel free to ask. Thanks! -

Control object creation flow in Django inheritance models
I have been read some Django document about inheritance models and parent_link. Suppose that I have these models: class Parent(models.Model): #Some field goes here! class Child(Parent): #Some field goes here! I have 3 questions about this pattern: What should I do if I want to create new child object and pass id of existing parent to that? What should I do if I want to create just new child object and after a while create parent object for that child? Also I din't understand this document about parent_link: OneToOneField.parent_link When True and used in a model which inherits from another concrete model, indicates that this field should be used as the link back to the parent class, rather than the extra OneToOneField which would normally be implicitly created by subclassing. Thanks for your help! -

Do I need to know Postgres if I want to use it in Django?
I have been developing backend for like 8 months and have done quite a few big projects, but in all of them I used sqlite database. I understand that using sqlite at production level is a bad idea. hence I want to use a Postgres database since I deploy my apps at heroku and it uses Postgres database. But if I do start using Postgres do I need to be able to use it, or would everything work just as the ORM would work with the sqlite database? I just know the basics of database, their relations and some basic SQL. Do I really need to learn more? Or should I just plug n play a database? -

Syntax Error when trying to makemigrations in django
I am a newbie in web design and I'm trying to design a web server using sentdex's Django Web Development video series. I am running the web server on a Raspberry Pi B+ with all the most recent software. I have followed sentdex's every step so far. The only difference is I was told to use a virtual enviroment when using django on a Pi so that's my only difference(other than updated software). In 12:37 of his second video when he uses the command "python manage.py makemigrations" (after adding the app name to the settings.py) his command prompt comes up with no errors while mine gives the error: Error Message Snip I have looked into adding django to the PYTHONPATH but I've also seen conflicting posts.

Django HttpResponse working with latin encode
I'm passing a json to the HttpResponse and I'm having problems with some special characters like 'ñ' or 'á'. this is my code in the views.py file: def count_depto(request): time = datetime.now() - timedelta(days=1) df = pd.DataFrame.from_records(RayosDepto.objects.filter(tiempo__gte=time).values()) grouped = df.groupby('dpto').size().to_frame() grouped.columns=[grouped[0].sum()] grouped.rename_axis('Total',inplace=True) grouped=grouped.transpose() grouped = grouped.to_json(orient='records',force_ascii=False) return HttpResponse(grouped,content_type='json') and this is my actual result: is there a way to fix this?Django version:3.0.5, pandas version:1.0.3
