But it is not working. # Use the hash sign to prefix a comment # +---------------- minute (0 - 59) # | +------------- hour (0 - 23) # | | +---------- day of month (1 - 31) # | | | +------- month (1 - 12) # | | | | +---- day of week (0 - 7) (Sunday=0 or 7) # | | | | | # * * * * * command to be executed cron.py def cronfunction(): logger.warning("========== Run Starts ====") logger.warning("========== Run Ends ======") If I am running this function every 2 or 3 minutes then it works fine.

Generate media url from file path in Django
Let's say I have a function that writes a file to MEDIA_ROOT: def write_file(): with open(settings.MEDIA_ROOT / 'myfile.txt') as file: file.write('foobar') Now I want the absolute URL for this file as it is served from MEDIA_URL. Does Django have any utility function to do this for me? Or do I need to build it myself? Note this file is NOT associated with a model's FileField. -

Django - HTMX: Render forms errors on modal and keep user on same page?
may you help me to understand how to use HTMX to render Form's Error messages when form is invalid? Docs says to use an attribute like : hx-post="{% url 'accounts:login' %}" but since I'm already using method=post should I still use it or delete it?I'd like users to stay on current page, however, right now when form is invalid users are redirected here: http://127.0.0.1:8000/accounts/login/ I didn't find a javascript function that opens the modal, so I think it is openened by some javascript implemented by bootstrap itself. this is my form: <form class="row my-4 align-items-center" method="post" action="{% url 'accounts:login' %}"> {% csrf_token %} {{ login_form.as_p }} {% if login_form.errors %} <ul> {% for field_errors in login_form.errors.values %} {% for error in field_errors %} <li>{{ error }}</li> {% endfor %} {% endfor %} </ul> {% endif %} <button type="submit" class="btn btn-primary">Ingresar</button> </form> ``` views: def login_view(request): if request.method == 'POST': login_form = LoginForm(request, data=request.POST) print("### Request is post") if login_form.is_valid(): print("### Request is VALID") username = login_form.cleaned_data.get('username') password = login_form.cleaned_data.get('password') print("User name", username, "type: ", type(username)) print("Pass", password, "type: ", type(password)) user = authenticate(request, username=username, password=password) if user is not None: login(request, user, backend='django.contrib.auth.backends.ModelBackend') return redirect("/") else: print(login_form.errors.as_data()) return JsonResponse({'success': False, … -

Why is my Django database flush command not working?
I've been chasing an error message regarding the python manage.py flush command for several weeks. When I issue the command and confirm the flush....I get... CommandError: Database my_app_db couldn't be flushed. Possible reasons: The database isn't running or isn't configured correctly. At least one of the expected database tables doesn't exist. The SQL was invalid. Hint: Look at the output of 'django-admin sqlflush'. That's the SQL this command wasn't able to run. After chasing...upgrading various components...trying several different avenues....I still can't figure this out. -
Django: How to get tax amount for diffrent countries and multiply it by product price in django?
I am creating an ecommerce system where i would need to calculate taxes for diffrent countries during checkout. I have added a flat rate for the tax, but that is not how tax works, it need to be percentage based which i have done, but how do i know the country a user is about to order a product from and also get the tax amount for that country and do my basic calculation. please if you have done this before i would really appreciate any help as that would help me fix this issue. Right now, this is how i am performing the tax calculation with a fixed percentage for all users from all countries new_tax_amount = 0 tax_amount_by_percentage = 25 / 100 # 25% / 100 = 0.25 new_tax_amount += int(item['qty']) * float(tax_amount_by_percentage ) This works well for me, but i need to know how to get tax percentage based on the country the user is trying to order the product from -

Is it possible to configure CSRF_TRUSTED_ORIGINS in Django 4 to allow access from any IP address?
I have found several posts regarding this but did not find what I need. I have upgraded Django from 2.x to 4.x for an Angular/Django web app which will be packaged and distributed to users that will install in different hosts and domains. MOST IMPORTANTLY, they would need to access the app from multiple locations on a serving port via browser (i.e. HTTP://whereAppIsInstalled:PORT). This used to work in Django 2 used to work without CSRF_TRUSTED_ORIGINS and with the settings below: ALLOWED_HOSTS = ['*',] CORS_ORIGIN_ALLOW_ALL = True All the answers say that I need to add those hosts, IPs, or subdomains to the CSRF_TRUSTED_ORIGINS list in settings.py. This works, but impractical in my case since I don't know all the hosts and IPs. I also noticed in Django documentation that we could add "HTTP://..." to CSRF_TRUSTED_ORIGINS, but this does not seem to work. I have to explicitly list all the IPs of the machines I am using to access the app. What should I do in this situation? How do I make sure that my app allows requests from all IPs? -

How to find duplicates of django model on two fields?

I can do this manually, but I want to know if there is a feature of django that takes care of that.

Why does jQuery script behave differently in webpack?
As a learning exercise I'm attempting to reproduce a PHP\Symfony project in Python\Django. While working in Django I rewrote a jQuery script that I think is more effective than what I used in Symfony. Oddly, the identical script (i.e., copied & pasted) does not perform the same as in Django. Here's the script and an outline of what it does. The page on which the script operates contains two versions of the same table. One side is the food that is "assigned" to a meal. The other side has the food items available to be added to the meal. When the page is rendered it receives a JSON array of data attributes of foods already assigned to the meal. The script steps through the assigned table, hiding the table rows of food not assigned. It also hides the table rows of food items available that are assigned. The script: var rArray = JSON.parse($("#rte").text()); $("table#ready_foods tbody tr").each(function () { f = $(this).find('td').data('foodid'); if (rArray.indexOf(f) == -1) { $(this).toggle(); } else { $("table#meal_pantry tbody tr td[data-foodid=" + f + "]").parent().toggle(); // never executed } }); In Symfony, the else statement is never executed. So regardless of the foods already assisgned, that table's … -
How to print actual number when using Aggregate(Max()) in a Django query
I have the following query set: max_latitude = Model.objects.aggregate(Max('latitude')) When I print it, it returns {'latitude__max': 51.6639002} and not 51.6639002.
