Django-Templates: Is there a middle ground between extend and include?
I am developing a webpage with Django and I came across the problem of having certain reocurring elements within a webpage. The base layout inluding the menue for instance wraps the rest of the webpage and can thereby be outsourced by extend. Similarly if I have a reocurring element that is completly wrapped by the current webpage without altering html inside it can be implemented by using include (for instance a specific Button). However I have a third category where I do not know how to outsource redundant information: Lets say I have a card design, that always certain propery and contains of a div, with a header an image and content. I want to reuse this design displaying different contents and i also have different cards on the same page, how do I do that? Is this really the way to go: card_x.html: {% extend 'card_template.html' %} {% block title %} Title x{% endblock title %} {% content %} Content x {% endblock content %} ... card_template.html: <div> <h1>{% block title %} {% endblock title %}</h1> <div> {% content %} {% endblock content %} </div> </div> mainpage.html: {% include 'card_1.html' %} {% include 'card_2.html' %} {% include 'card_3.html' %} … -
DRF CSRF cookie not set
I have a DRF project, with an endpoint path('api/auth/', include('rest_framework.urls')), When sending a POST request from Postman to the endpoint api/auth/login/, in order to login with an existing user. I get the following error Forbidden (403) CSRF verification failed. Request aborted. You are seeing this message because this site requires a CSRF cookie when submitting forms. This cookie is required for security reasons, to ensure that your browser is not being hijacked by third parties. If you have configured your browser to disable cookies, please re-enable them, at least for this site, or for “same-origin” requests. Help Reason given for failure: CSRF cookie not set. I tried to set a csrf header (X-CSRFTOKEN, XSRF-TOKEN). I also logged in with the user from the DRF API interface and found the value for X-CSRFTOKEN, which I set in Postman with no success. I also tried to tweak many settings in setttings.py such as (CSRF_COOKIE_NAME, CSRF_TRUSTED_ORIGINS .. Also, to mention the POST method is working on other endpoints for creating objects. I am so thankful if anyone would have an idea. -

{TypeError} '<=' not supported between instances of 'CombinedExpression' and 'datetime.date'
I'm new in django and I want to filter my model with certain conditions: for example get only team expired after 7 days. This is my django query: current_date = datetime.datetime.today().date() MyModel.objects.filter( Q(end_date__lt=current_date) & Q(locked=False) & Q(F('end_date') + datetime.timedelta(days=7) <= current_date) ).values('id') end_date is DateField.

Django cannot find 'myapp.setting' via django.setup() when running my script as a module
I'm working on a rather elaborate project and have run into some confusion regarding why I get a ModuleNotFoundError: No module named 'burrow.settings' (I called it myapp.settings in the title for better searchability) when calling __main__.py by running $ python -m burrow, but $ python burrow works perfectly well! I have no relative imports anywhere in my code and haven't touched the boilerplate generated by Django, and have tried and searched all kinds of things and can't find out why this is behaving differently, so any insight would be greatly appreciated! The repository structure may be a little confusing (suggestions for improvement welcome), but effectively consists of a single Project (meercat) consisting of two sub-packages (burrow and lookout) which represent a server and a client respectively. Within the server package (burrow), there is the regular Django boilerplate (burrow/burrow) as well as a Django REST Framework app (api). meercat - data - docs - meercat - burrow - api // newly created - burrow // created with startapp, untouched - __init__.py - __main__.py - controller.py - manage.py - env - lookout - __init__.py - core.py README.md Relevant code: # __main__.py import argparse as ap import logging import os import sys import … -

Converting string to Django model name before calling filter() (Not duplicate)

How to redirect two different Django applications on the same server with same url but different paths?

How to document a tuple with different data types using drf-spectacular?
I'm using drf-spectacular to generate a Swagger documentation. I have a viewset that returns a dict (it doesn't go through a drf serializer as it's all native objects).
