Django DTR and ZKTeco Biometric device Pull Attendance Data Implementation
This is my implementation of the ZKTeco Biometric device with Django. I am new to this and I would like to ask if what else and how to improve this code. I am using the pyzk library. After a very long research in the creation of this, I am planning to 'get all attendance data from all biometric devices first and save only the earliest attendance time per employee', But I am not doing it now because of the deadline, at least I have a working prototype now. Thank you in Advance. from zk import ZK, const from datetime import datetime import subprocess import logging import traceback from dtr.models import AttendanceRecord, DailyAttendance, AllAttendanceRecord def is_device_reachable(ip_address): try: # Use a short timeout for the ping to avoid long delays response = subprocess.run(["ping", "-c", "1", "-W", "1", ip_address], stdout=subprocess.PIPE, stderr=subprocess.PIPE, check=True) return response.returncode == 0 except subprocess.CalledProcessError: return False @login_required(login_url='/admin') def getAllAttendance(request, start_date, end_date): status = 'success' message = '' start_date = datetime.strptime(start_date, '%Y-%m-%d').date() end_date = datetime.strptime(end_date, '%Y-%m-%d').date() devices = BiometricDevice.objects.filter(status=1) attendance_data_list = [] try: for device in devices: if is_device_reachable(device.ip_address): try: zk = ZK(str(device.ip_address), int(device.port)) conn = zk.connect() current_time = datetime.now() conn.set_time(current_time) conn.get_device_name() conn.enable_device() all_attendance_data = conn.get_attendance() attendance_data = [record for … -
Django Cookie Cutter With Docker: django.core.exceptions.ImproperlyConfigured: Set the DATABASE_URL environment variable
I have looked at many other posts with similar issues but no one seems to have used django cookie cutter with docker to build their django project.

When adding a checkbox next to a password input it breaks
So I am making a sign in page and I wanted to add a show password button. But when I put the checkbox next to the button it makes it look awful and uneven. Heres a picture. enter image description here And heres the code: {% extends 'myapp/base.html' %} {% block content %} <h1>Sign up </h1> <input type="text" id="username" placeholder="Username"> <br> <input type="email" id="email" placeholder="Email"> <br> <input type="password" id="password" placeholder="Password"> <input type="checkbox" onclick="show('password')"> <br> <input type="password" id="passwordC" placeholder="Confirm Password"> <br> <input type="submit" value="Submit"> I tried styling it with css but that only made it worse. I also looked through stack overflow but nothing worked. This is using django if that helps. -

Django Limit Queryaset Objects by Foreign Key
Sorry for this question but I'm reasonably new to Django and it's eluding me. I am updating a system (think school) with users, classes (the teachable kind), etc. I have classes from the legacy system I want to bring into the new system, and I need to limit the list by a legacy_user_id. So far, I have this in models.py from account.models import Profile, LegacyUser class OldClassesManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(LegacyUser.legacy_id) class OldInstructables(models.Model): legacy_user_id = models.IntegerField(null=False) name = models.CharField(max_length=100, blank=False) [other stuff] objects = models.Manager() SOMETHING = OldClassesManager() def __str__(self): return self.name And this in views.py class OldClassList(ListView): model = OldInstructables I think my problem is that I don't know what goes where I put SOMETHING. Any help or insight would be much appreciated. -

setting up pgadmin4 on a VPS running ubuntu. Configuring it from nginx

How can Django not see a defined url?
I've recently started learning Django for my course project, and my app works perfectly on my local machine. However, when another person clones the project from GitHub and runs it via Docker Compose, he gets an error 404 (trying to access the form/): Using the URLconf defined in app.urls, Django tried these URL patterns, in this order: admin/ api/ trText/ [name='tr_text'] The current path, api/form/, didn’t match any of these. The app/urls.py is: from django.contrib import admin from django.urls import path, include urlpatterns = [ path("admin/", admin.site.urls), path('api/', include('aitranslate.urls')), ] The aitranslate/urls.py is: from django.urls import path from .views import tr_text, translator urlpatterns = [ path('trText/', tr_text, name='tr_text'), path('form/', translator, name='translator'), ] Why does it see trText/ but doesn't see form/? And how can it work on my local machine without this problem? I would appreciate any help. -

Django custom domains feature
I'm currently working on a Django project that allows our users to create their own websites. One of the main features I've been working with is setting up custom domain capabilities. Here's what I did: I initially set the ALLOW_HOST setting to "*", then I've since devised a middleware to manage domain routing: First, it checks whether the host (using request.get_host()) corresponds to www.domain.com. If so, the middleware directs the request to the homepage application using the request.urlconf attribute. Next stop is checking if the host matches dash.domain.com. If it does, voila! The request gets routed to the dash app. And here's where it gets interesting. If neither of the above conditions is met, the middleware dives into the database to see if the host matches any of the registered site domains. If it finds a match, it redirects to the sites app with all the site-specific info. If not, it gracefully returns a 404 error. I've been thinking about the safety aspects of this configuration since ALLOW_HOST setting is "*", and I'd like your opinion. Do you think this approach is robust enough? -

How to Set Event Reminders in Google Calendar for Multiple Users using Python API without Explicit Consent?
I'm developing an application where I need to set event reminders in multiple users' Google Calendars without explicitly asking for their permission.

Django Q implement to send periodic emails
I have a Django project with several merchant accounts. When they log in using a URL, a certain view is called that aids with login and authentication. In addition, the same method determines if the merchant's plan expires in a month. If so, the function notifies you by email about the same problem. The problem now is that the view function won't execute if the user doesn't log in, which means he won't get any mail. Can I then have an automatic feature that delivers the mail and verifies each merchant? To notify merchants of their plan expiration even if they don't log in, I want a function in Djnago-Q to run even if the URL is not hit and after a set amount of time. -
