Time and date calculations DJango
So i have a data entry project using django and i have those 4 fields representing the: start_date, start_time, end_date, and end_time {% block content %} <h1>Form Page</h1> {% csrf_token %} {{ form.start_date.label_tag }} {{ form.start_date }} {{ form.start_time.label_tag }} {{ form.start_time }} {{ form.end_date.label_tag }} {{ form.end_date }} {{ form.end_time.label_tag }} {{ form.end_time }} {{ form.duration_hours.label_tag }} {{ form.duration_hours }} Submit {% endblock %} so the thing that i need is to make a listener for those 4 field values and whenever the user entered the first 3 values and start filling up the forth one which will be the end time the duration_hours field will start to calculate the difference between and give me the value of the duration time. All models,forms python files are correct i just want to know how i can do it I tried to make a script in the html file like this : <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.3/jquery.min.js"\>\</script\> $(document).ready(function(){ // get the values of the start and end date/time fields var start_date = $("#start_date input").val(); var start_time = $("#start_time input").val(); var end_date = $("#end_date input").val(); var end_time = $("#end_time input").val(); // combine the start date/time and end date/time into Date objects var start_datetime = new … -

Pytest-django does not seem to create a new database for each test
When I run a test that needs the database, it seems to use the existing database (when I change a database entry, the test error contains the changed database entry). But I expect that pytest-django creates a new database for each test (if not specified differently). When debugging it calls the custom django_db_setup and the pytest django_db_setup fixture. It also outputs in the log statement: "Running migrations: Applying ..." but the test fails when I manipulate the data in the existing database. Could it be that the problem is there because we use an in memory Sqlite database? Or do I need some other setting? Or is this a bug? Test: def test_should_show_the_city_name_in_city_select_dropdown(page: Page, django_db_setup): page.goto("/") city_select_button = page.get_by_text("Stadt auswählen") city_select_button.click() assert "Beispielstadt" in page.get_by_role("listitem").all_inner_texts() conftest.py import os import pytest from django.core.management import call_command from config.settings.base import BASE_DIR os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true" @pytest.fixture(scope="session") def django_db_setup(django_db_setup, django_db_blocker): with django_db_blocker.unblock(): call_command( "loaddata", os.path.join(BASE_DIR, "e2e_tests", "database", "test_database.json"), ) pyproject.toml [tool.poetry.dependencies] python = "^3.10" django = "^4.1.6" [tool.poetry.group.dev.dependencies] pytest = "^7.2.1" pytest-playwright = "^0.3.0" pytest-base-url = "^2.0.0" pytest-django = "^4.5.2" [tool.pytest.ini_options] base_url = "http://localhost" DJANGO_SETTINGS_MODULE = "config.settings.local-container" database settings DATABASES = { "default": { "ENGINE": "django.db.backends.sqlite3", "NAME": Path("/") / "db" / "db.sqlite3", } } -

How do i limit choices for a field in a django model with respect to the data in previous field using foreignkey and limit_choices_to attribute?

But am getting this error when trying to execute makemigrations. ValueError: This queryset contains a reference to an outer query and may only be used in a subquery. i was expecting to get a single choice for payment_property whenever i create a new Payment object and select a Tenant object, the available choices for the payment_property field should be limited to Property objects that have the same unit_name as the rent_unit of the selected Tenant object. -

get user group name from a specific text in django
In django, user posts in a simple HTML form. In form, there is a field which called "technician_name". I'm getting the post with "name attribute" and write it to database. I want additional thing: after I take the name attribute, I want to check the group of technician. Simply: I want to check user's group according to specific text. For example: user posted the "John Doe". if request.method == 'POST' action_man = request.POST.get('technician_name') Output: action_man = "John Doe" I need this action_man's user group. The action_man's name same with username, so I can query in django auth. Note: I don't need the logged in user's group. I need action man's group. -
Avoid CSRF_TRUSTED_ORIGINS in Django 4.1
I've a dockerized Django project which I access through NGINX.

I've tried installing https://github.com/ottoyiu/django-cors-headers and setting CORS_ALLOW_ALL_ORIGINS to TRUE but it didn't work :/ Also I tried setting CSRF_TRUSTED_ORIGINS = ['*'] as I have in ALLOWED_HOSTS but it doesn't work...
