Django settings.py with additional imports odd behaviour and email errors [Errno 111] / clarification on best practice
I've noticed some strange behavior with Django and hope to get a better clarification on why that is. This is in part related to questions like this one (Django Email Error) but goes into more depth wondering about best practices. Look at the following setup: In order to not "overload" my settings.py in my main app I am importing additional sub-settings files. My structure is something along the lines of: main_app -settings.py ... utils_app config -settings_email.py -settings_something_else.py ... utils -email.py ... ... 'email.py' contains the send_email() function and the main_app settings.py file imports as follows: from utils_app.config import settings_email And settings_email.py would look something like: EMAIL_HOST='some-host' EMAIL_PASS=os.environ.get('EMAIL_PASSWORD') EMAIL... ... Originally those variables were in my (default) main_app settings.py file. When that was the case sending email via the Django 'send_mail' function was fine. Once I've moved them out importing as above it stopped working unless I specifically name them when importing like so for example: from utils_app.config.settings_email import EMAIL_HOST, ... In the Django send_mail documentation I couldn't see anything regarding this issue. So the first question is: does Django indeed not know where to look for those variables other than default settings.py and they have to be named there specifically, … -
Django admin: how to display number with fixed length?
This is my model: from django.contrib.humanize.templatetags.humanize import intcomma class Flow(models.Model): amount = models.DecimalField(max_digits=10, decimal_places=2) def df_amount(self): return '{intcomma(abs(self.amount)):>12}' df_amount.admin_order_field = 'amount' df_amount.short_description = 'amount' In admin.py, @admin.register(Flow) class FlowAdmin(admin.ModelAdmin): list_display = ( 'df_amount', ) For amount=2800, print(self.df_amount()) gives $ 2,800.00 but $ 2,800.00 is displayed in the admin panel where the spaces in the middle were truncated to only one space, not as expected. So my question is how to reserve the spaces in the middle of the string in admin panel? Thank you! -

How to map a patch method over an action with detail=False in Django Rest Framework

Django - Data import from JSON file URL into Database
I'm trying to import data from a json file URL into my Django Database on a weekly basis to keep my Database up to date. That Data is coming from an Importer which was written in GO and which provides me with that JSON File via a link.

Chained dropdown + label on Django

Best approach to send requests in Django

In many queries i should pass auth credentials, and as i use default Django auth system i need to pass token and session id. So now queries are done using requests lib like following: #function to create full url for api def create_api_request_url(request, reverse): return 'http://' + request.get_host() + reverse #getting csrftoken and session id, return cookies and header, need for authorization class CookieManager: @staticmethod def get_auth_credentials(request): ses_id = request.session.session_key token = get_token(request) cookies = {'csrftoken': token, 'sessionid': ses_id} headers = {'X-CSRFToken': token} return {'cookies': cookies, 'headers': headers} def some_view(request, pk): ... #create full api url url = create_api_request_url(request, reverse('Shopping Cart API:Cart')) #collect auth credentials from request object credentials = CookieManager.get_auth_credentials(request) #make request using import requests, provided data and auth credentials requests.post(url, {"amount": product_amount, "product": pk}, **credentials) So i need to go into so many steps and use my own custom functions just to send request.

'django_js_reverse', ... ] I collected static ...but still I can't manage to load it. ./manage.py collectstatic_js_reverse I added this line to load the script in my template <script type="text/javascript" src="{% static 'action/js/project_dashboard.js' %}"></script> However, when I load my page and check the developer console, I can see that the import of the .js failed. The frustrating thing is that I manage to import other .js files that I made so the overall collectstatic process is working. Ideas? -
Django tutorial: ImportError: attempted relative import with no known parent package
I keep running into an error trying to execute the Django Writing your first Django app tutorial. I am running Windows 10, Python 3.9.6, Django 3.2.9, and Vscode 1.63.0. I'm on the step where I create a URLconf file called urls.py in the polls directory. The polls directory is at the same level as the manage.py script and the mysite folder (see folder structure screenshot below). Prior to this, I copy/pasted the code in the views.py, which runs fine.
