I am getting a no such column error only when running tests
Perhaps this is leaving out some key detail and exposing my relative newness to django, but I tried to isolate my issue to the fewest steps to reproduce the problem. Starting state: App running fine, tests all passing. Add one nullable column to an existing model. makemigrations migrate New state: App runs fine, running tests produces an error. Creating test database for alias 'default'... Found 23 test(s).

raise ImproperlyConfigured("SECRET_KEY setting must not be empty")django.core.exceptions.ImproperlyConfigured:The SECRET_KEY setting must not empty
I published my Django project into github and I had a lot of variables that stored in .env for secure. And when anyone clone that project and migrate its not reading variables in my .env file that saved in .gitignore. is there any solution without showing these value of the variables, or it's ok and no danger to show this info? ``` import os from pathlib import Path from dotenv import load_dotenv load_dotenv() SECRET_KEY = os.getenv('SECRET_KEY') CURRENT_HOST = os.getenv('CURRENT_HOST') DATABASE_NAME = os.getenv('DATABASE_NAME') DATABASE_USER = os.getenv('DATABASE_USER') DATABASE_PASSWORD = os.getenv('DATABASE_PASSWORD') DATABASE_HOST = os.getenv('DATABASE_HOST') DATABASE_PORT = os.getenv('DATABASE_PORT') HOST_EMAIL = os.getenv('EMAIL_HOST') EMAIL_USER = os.getenv('EMAIL_HOST_USER') EMAIL_PASSWORD = os.getenv('EMAIL_HOST_PASSWORD') PORT_EMAIL = os.getenv('EMAIL_PORT') EMAIL_TLS = os.getenv('EMAIL_USE_TLS') SOCIAL_AUTH_GOOGLE_KEY = os.getenv('SOCIAL_AUTH_GOOGLE_OAUTH2_KEY') SOCIAL_AUTH_GOOGLE_SECRET = os.getenv('SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET') ``` .gitignore has .env inside, So I thought that it's may be related to the one in my device. I know that it's impossible but i did not find any solution so i hope that anyone can help me, Thanks. -
html button not work on each click - hot to debug it? (chrome)
I've got a (django) app, that displays a page with videojs-record, with ability to record something and send to backend. In general both recording and sending works fine. But - after recording there is a button to send (button with id=submit), and the click there works sometimes immediately, sometimes, I need to click it two or three times, to make it work. After sending, the button is hidden, and another one is showed to move to next question. And the behaviour is similar - it works sometimes, and sometimes needs to be clicked couple of times. I've no idea how to debug it... {{questionText}} <video id="myAudio" playsinline class="video-js vjs-default-skin"></video> <button class="btn btn-sm btn-primary" id="submit" disabled>sent</button> <a href="{% url 'video2_module:NextQuestion' %}" id="next" style="display: none;" class="btn btn-sm btn-primary" >next-> </a> <input type="hidden" id="myVar" name="variable" value="{{ file_name }}"> <script> $(document).ready(function () { var options = { controls: true, bigPlayButton: false, loop:false, width: 480, height: 360, fluid: false, plugins: { record: { audio: true, video: { // video media constraints: set resolution of camera width: { min: 480, ideal: 480, max: 480 }, height: { min: 360, ideal: 360, max: 360 } }, // dimensions of captured video frames frameWidth: 480, frameHeight: 360, maxLength: … -
Which way is better to store data about Transactions? (Django)
I need to store data about Transactions in Django (Postgres). There are different type of transactions (replenishment of balance, withdrawal from balance, payment of salaries, purchase of equipment, parking expenses, bonuses and etc.). Depend on type of transaction I need to store different data, for example: For replenishment of balance and withdrawal from balance - customer (Id of customer, can be empty), date, comment, total For salaries - employee (Id of employee), date, comment, sub total and total (there may be bonus or fine) For purchase of equipment - provider (Text), date, comment, total For parking expenses - date, comment, total Also I need to implement API (to retrieve salaries, transactions of client, all transactions, sum of all expenses, sum of all income and etc.) Also it will be good if Admin would be able to add custom transaction types (I think that it's not a good idea to store transaction type as a String, because it may cause some problems if Admin put wrong data (For example: "Salari" instead of "Salary")) So, here are my questions: Is it a good approach to store all Transactions in one table (Model) or it's better to split them and why? Any ideas … -

Filter a query set depending on state at a given date
Given the following model (using django-simple-history): class MyModel (models.Model): status = models.IntegerField() history = HistoricalRecords() I would like to get all instances that didn't have a certain status on a given date (i.e. all instances that had a different status on the limit date, plus all instances that didn't exist at that time). The following query will return all instances that never had status = 4 at any point before the limit date: MyModel.filter (~Exists ( MyModel.history.filter ( id = OuterRef ("id"), history_date__lte = limit_date, status = 4)) But unfortunately it also removes instances that had status = 4 at some past date, then changed to a different status by the limit date, and I want to keep those. The following should give the correct result: MyModel.filter (~Exists ( MyModel.history.filter ( id = OuterRef ("id"), history_date__lte = limit_date) .order_by ("-history_date") [:1] .filter (status = 4))) Unfortunately it doesn't work: Cannot filter a query once a slice has been taken. This question links to this documentation page which explains that filtering is not allowed after the queryset has been sliced. Note that the error comes from an assert in Django. If I comment out the assert in django/db/models/query.py:953, then the code … -

Django csrf token cannot be read
I am writing a website with Vue as a frontend framework and django as a backend framework. I have included the csrf token in every single request from my frontend to my backend to ensure that I dont get a 403 Forbidden error. All requests are ok and function normallu.

The frontend and backend both run with no issues, its just that no requests to the backend can be performed.
