Django: Generate random time in a within a specific day and insert multiple rows to database
I have a schedule for user in which it will generate randomly. For example I want to create and schedule for tomorrow, the admin will choose a day and N number of report a day. So the no_of_route is the # of rows to insert in database and also the # of generated hours and the # of route it will select from RoutePoints class. So, I really don't know to to generate hours. And this is where it should be. no_of_route = request.POST.get('no_of_route') date = request.POST.get('date') # generate hours, if no_of_route is 3, it would be 9AM, 1PM, 5PM hour = ... This is how I select random route id. items = list(RoutePoints.objects.all()) random_route = random.sample(items, no_of_route)[0] And this where I create multiple of rows. I'm not really sure how to do it. Schedule.objects.bulk_create(route=items.id, time=hour, date=date) Hope someone see this. Thank you in advance! -

How to Enable DEBUG Logging in Django?
I'm currently working on implementing logging in my Django project, but I'm encountering an issue where calls to logger.debug('log') do not output anything. I suspect there might be something wrong with my logging configuration. Below is the LOGGING configuration from my settings.py: logger = logging.getLogger(__name__) logger.debug(f"debug from logger") DJANGO_LOG_LEVEL = "DEBUG" LOGGING = { 'version': 1, 'disable_existing_loggers': False, "formatters": { "verbose": { "format": "{levelname}: {message} ({process:d}:{thread:d}::{filename}:{lineno}::{asctime})", "style": "{", 'datefmt': '%Y-%m-%d %H:%M:%S', }, "simple": { "format": "{levelname}: {message} ({filename}:{lineno})", "style": "{", }, }, 'handlers': { 'stdout': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'simple', }, "file": { "level": "INFO", "class": "logging.FileHandler", "formatter": "simple", "filename": logs_path.joinpath(f"{STAGE}-django.log").as_posix(), }, "mail_admins": { "level": "INFO", "class": "django.utils.log.AdminEmailHandler", "include_html": True, }, }, 'loggers': { '': { 'handlers': ['stdout', 'file'], 'level': 'DEBUG', 'propagate': True, }, 'django': { 'handlers': ['stdout', 'file'], 'level': 'WARNING', 'propagate': True, }, "django.request": { "handlers": ["mail_admins"], "level": "ERROR", "propagate": False, }, }, } Some can help me to figure out what's wrong with my logging configuration? -
DJANGO [WinError 10061] email features
I'm working in a Django project that uses the mail features. When try to send the mail I got this error message: [WinError 10061] No connection could be made because the target machine actively refused it. I'm using an email with godaddy domain. This is my configuration: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtpout.secureserver.net' EMAIL_USE_TLS = True EMAIL_PORT = 587 EMAIL_HOST_USER = 'mymail' EMAIL_HOST_PASSWORD = 'mypassword' I have tried all the related questions like: How to fix ConnectionRefusedError: [WinError 10061] the target machine actively refused it? (Django e.mails) I checked the firewall and none of the ports like 587, 25, 465, etc. were blocked. I also tried to connect with office365 server and didn't work. I don't know if this worth, but I have errors connecting with some pages for example when I run pip install library, gives an error related to SSL certification and only works if I bypass with --trusted-host. Maybe in this case I need to use something similar. -
Django - How to filter model objects by certain attribute and use it for front-end?
I am a beginner and building a website to showcase wines. This is the model for Wine: class Wine(models.Model): name = models.CharField(max_length=100) type = models.CharField(max_length=50) description = models.TextField() image = models.ImageField(upload_to='images/wines/') keywords = models.CharField(max_length=255, blank=True) def __str__(self): return self.name I added a page called "Advanced Search" which should initially show all the wines. I want to implement filtering functionality so when I select the corresponding checkboxes, the wines should be filtered by their keywords. Currently the keyword field accepts string as input. For example Wine1 has the following keywords: "red, plum, citrus". But the keywords field accepting string is not necessary (please suggest other approaches if needed). In my HTML file I added some checkboxes to test. The checkboxes correspond the keywords. So if I check the "plum" and "red" checkboxes, only the wines which contain those keywords should be shown. Here is the html part of the page: <div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-expanded="false"> Filter </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton" id="filterOptions"> <li><input class="form-check-input" type="checkbox" id="redCheckbox" value="red"><label class="form-check-label" for="redCheckbox">Red</label></li> <li><input class="form-check-input" type="checkbox" id="sparklingCheckbox" value="sparkling"><label class="form-check-label" for="sparklingCheckbox">Sparkling</label></li> <li><input class="form-check-input" type="checkbox" id="whiteCheckbox" value="white"><label class="form-check-label" for="whiteCheckbox">White</label></li> <li><input class="form-check-input" type="checkbox" id="sweetCheckbox" value="sweet"><label class="form-check-label" for="sweetCheckbox">Sweet</label></li> <li><input class="form-check-input" type="checkbox" id="dryCheckbox" value="dry"><label class="form-check-label" for="dryCheckbox">Dry</label></li> … -

Why are permissions not being overridden for a viewset?
I have created a viewset for authentication. Since this is the authentication viewset, I want this viewset to be accessible to unauthorized users as well. Following DRF documentation, this is what I have: class AuthenticationViewSet(viewsets.ViewSet): permission_classes = [AllowAny] def create_user(self, request: Request) -> Response: #code for creating a user Since I want the other viewsets to be accessible only to the authorized users, I set the following in settings.py: REST_FRAMEWORK = { "DEFAULT_PERMISSION_CLASSES": ["rest_framework.permissions.IsAuthenticated"], "DEFAULT_AUTHENTICATION_CLASSES": [ "authentication.token_auth.ExpiringTokenAuthentication" ] } When I make an API call to the create_user endpoint, I get an error saying: "No token found". Why is this happening? Shouldn't the permissions be overridden based on the permission_classes list in the viewset? For reference, my authentication class: class ExpiringTokenAuthentication(TokenAuthentication): def authenticate(self, request): if COOKIE_KEY in request.COOKIES: token_key = request.COOKIES[COOKIE_KEY] else: raise exceptions.AuthenticationFailed("No token found") try: token = Token.objects.get(key=token_key) except Token.DoesNotExist: return exceptions.AuthenticationFailed("Invalid token") if isTokenExpired(token): raise exceptions.AuthenticationFailed("Token has expired") user = token.user return (user, token) def isTokenExpired(token): currentTime = datetime.now(datetime.UTC) currentTimeUTC = currentTime.replace(tzinfo=pytz.UTC) return token.created < currentTimeUTC - timedelta(hours=TOKEN_EXPIRE_HOURS) -

Django 5.0: How to create an object without retrieving the Foreign object instance related to it?
Currently I have some Django models defined like this: Class Project(models.Model) data = ... Class Resource(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) In my views.py im trying to create a new Resource, having access to the Project id thanks to the URL: def create_resource(request, project_id): """ Create a resource for a given project """ new_resource = Resource.objects.create(project_id=proyecto_id) return render(request,"resource.html",{"new":new_resource}) Here I am trying to create the Resource without fetching the related Project (which seems more efficient to me given I don't need the project for anything). To do this i used the notation described in the docs project_id to get to the FK id. But it doesn't work, Django says the following when I try to render the page: ValueError at /create_resource/1 Cannot assign "1": "Resource.project" must be a "Project" instance. I've found similar questions online, and all of them use the foreignfield_id notation to do this, but in my case it doesn´t work. Granted, I've only found questions from 10-15 years ago, so did this change somewhere along the way? My Django version: 5.0.3 Related question posted 13 years ago: Post -

Why does evaluating enviroment variable in setting.py does not work?
I set an environment variable here ~/.bashrc by adding export DJANGO_DEVELOPMENT='True' the committing the changes with source ~/.bashrc Then I checked if the value was correctly wrote with echo $DJANGO_DEVELOPMENT -->RESULT: true Now I'm simply triyng to accede this variabile during the server launch, so Django can figure out I'm in development and override the settings.py file with a settings_dev.py file. The code doing this in setting.py is: import os if os.getenv('DJANGO_DEVELOPMENT') == 'true': from .settings_dev import * The problem is that the server is always executed with DEBUG = False so I know as a fact that python is not reading properly the env. variable. I also double checked by putting a print(os.getenv('DJANGO_DEVELOPMENT')) but it's always None. Someone have any idea where my error is? Thanks in advantage. -

This is the QuizForm: class QuizForm(forms.Form): """QuizForm used to display questions with their options.""" def __init__(self, *args, **kwargs): questions = kwargs.pop('questions') super(QuizForm, self).__init__(*args, **kwargs) for question in questions: choices = [ ('option1', question.option1), ('option2', question.option2), ('option3', question.option3), ('option4', question.option4), ] self.fields[str(question.id)] = forms.ChoiceField( label=question.question_text, choices=choices, widget=forms.RadioSelect(attrs={'class': 'form-check-input'}) ) And this is the html form: <form method="post"> {% csrf_token %} {% for field in form %} <div> <label class="question">{{ field.label }}</label> {% if field.errors %} <ul class="errors"> {% for error in field.errors %} <li>{{ error }}</li> {% endfor %} </ul> {% endif %} <div> {% for choice in field %} <label class="form-check-inline"> {{ choice }} </label> {% endfor %} </div> </div> {% endfor %} <button type="submit">Submit</button> </form> I also tried other methods for getting the random objects from here: Django get a random object and https://books.agiliq.com/projects/django-orm-cookbook/en/latest/random.html. I think the problem is within the QuizForm but i cannot figure out where. -
Is it worth studying django in 2024
I am a novice web developer and recently finished learning python, now I want to move on and try to make the first real project with a working backend. After reading about different frameworks, I liked Django. But recently, one of my friends told me that django is a big Clumsy machine, and if I really want to do backend, then it's better to study node.js or the same flask. I have not found any information from professionals on the Internet. And I decided to ask here, is django really so slow and outdated, and is it worth starting to study it now if I want to be competitive in the market? Tried to learn Django. Expecting good workplace.
