Django - how to display all users that are present?
I have created an attendance system in Django but I cannot seem to retrieve all users that are currently present. My code is displayed below: Models: class Meta: model = User fields = ("username", 'email', 'password1', 'password2') class is_Present(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(default=datetime.date.today) is_present = models.BooleanField(default=False) class clocked_Time(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(default=datetime.date.today) time = models.DateTimeField(null=True, blank=True) signed_out = models.BooleanField(default=False) views.py: # Displays admin attendance portal functions def attendance_portal(request): if not request.user.is_authenticated: messages.warning(request, f'Please sign in to mark attendance out') return redirect('login') elif not request.user.is_superuser or not request.user.is_staff: messages.warning(request, f'Must be admin to access this feature') return redirect('home') elif request.user.is_superuser: count_employees_all = count_employees() # shows count of employees present_employee_all = present_employees() # shows count present employees today present_employee_all_week = present_week_employees() # shows count present employees in last 7 days # Gets the employees present today today = datetime.today() # Gets employees displayed and paginated user = get_user_model() user_list = user.objects.all() p = Paginator(is_Present.objects.filter(date=today).filter(is_present=True).select_related('user').values('user__username'), 5) page = request.GET.get('page', 1) users = p.get_page(page) try: users = p.get_page(page) # returns the desired page object except PageNotAnInteger: # if page_number is not an integer then assign the first page users = p.page(1) except EmptyPage: # if page is empty … -
Django confuses same DB name runs on different ports
I am running two different MongoDB on different ports and configured DB router to find the proper database. Also, the DB name and tables are the same in both. Assume that I have 2 app first_app and second_app where the DB connection names are the same as well. settings.py ... 'first_app': { 'ENGINE': 'djongo', 'NAME': os.environ.get("FIRST_DB_DATABASE", 'mymongodb'), 'CLIENT': { 'host': os.environ.get("FIRST_DB_HOST", "localhost"), 'port': 27019, 'username': os.environ.get("FIRST_DB_USER"), 'password': os.environ.get("FIRST_DB_PASSWORD"), } }, 'second_app': { 'ENGINE': 'djongo', 'NAME': os.environ.get("SECOND_DB_DATABASE", 'mymongodb'), 'CLIENT': { 'host': os.environ.get("SECOND_DB_HOST", "localhost"), 'port': 27020, 'username': os.environ.get("SECOND_DB_USER"), 'password': os.environ.get("SECOND_DB_PASSWORD"), } }, ... and here is the reason why app names are the same as connection names to find proper DB in router based on app name: db_router.py class MultiDatabaseRouter: app_labels = {'first_app', 'second_app'} mongodb_app_labels = {'first_app', 'second_app'} def db_for_read(self, model, **hints): if model._meta.app_label in self.app_labels: return model._meta.app_label return None def db_for_write(self, model, **hints): if model._meta.app_label in self.app_labels: return model._meta.app_label return None def allow_relation(self, obj1, obj2, **hints): return None def allow_migrate(self, db, app_label, model_name=None, **hints): """Do not migrate MongoDB.""" if app_label in self.mongodb_app_labels: return False return None Also, I have the same Models in both apps using the same db_table.

Passing a variable from views.py to models.py django
I am still very new to programming. My issue is this I have 2 models, one for Sale and one for Agent. now to render each Agent and the sales they made(with different attributes) uniquely I needed to write model methods under my sale model to allow to me to call them in the template. Now my issue is this, I want to be able to render that exact thing but by what dates the user chooses, I have tried manually doing this through my project files and it works, but I want to know is it possible to have those values moved from user into my method? What I mean is there is a basic form in the nav bar that allows the person to choose a from and to date, but those values I am not sure how to pass them into my models.py under the method where I need this date range applied. I will show an example. #this is my view that grabs relevant dates def asearch_stats(request): if request.method == 'POST': from_date = request.POST['from'] to_date = request.POST['to'] return render(request,"Sales/salesfilter.html",{"flookup":flookup}) # this is my model with the methods I'm referring to below: class SalesAgent(models.Model): user = models.OneToOneField(User,on_delete=models.SET_NULL,null=True,related_name="sauser") … -
Why am I not getting CSRF warning from django?
So usually when you try to make a POST request to the server in Django without CSRF token it gave you this page but for the past 3 months I've been playing with DRF and custom user model and I didn't even realized until now that I've actually not been getting that error despite not using CSRF in my postman header. There's also some more details made it more confusing to me first I made a post request to TokenObtainPairView from djangorestframework_simplejwt containing username and password (I'm using base user model) for login and it was successful Right after that I made another post request to add a title (a model that only have 1 field which is a charfield) and then it gave me CSRF warning I also have an almost identical project to this the only difference being the other projects uses custom user model and it never gave me any CSRF warning. So I suspect this has something to do with the user model somehow So to summarize my question: Why doesn't it gave me CSRF warning in the first POST request? does this have anything todo with custom user model? if so what am I missing? … -
Django DRF: Take extra input from user using serializer but not present in the model
I have one ModelSerializer class which is used for user input & validation. I am using it with a ModelViewset which automatically creates a new entry in the database using the serializer. Now what I want to do is that I want to have a extra field in the serializer say roles which will be given by the user. It is an array of roles for a user. So I wrote my serializer like this, class UserCreateSerializer(serializers.ModelSerializer): """ Serializer to create new user """ class Meta: model = User fields = ["name", "email", "is_active", "roles"] read_only_fields = ['roles'] roles = serializers.MultipleChoiceField(choices=[(e.name,e.value) for e in AuthGroup]) def validate_roles(self, value): if not value: raise ValidationError(detail=constants.NAMED_FIELD_REQUIRED.format(field="roles")) My model looks like this, class User(AbstractBaseUser, PermissionsMixin): class Meta: db_table = "auth_user" app_label = "users" USERNAME_FIELD = "email" REQUIRED_FIELDS = [] name = models.CharField(max_length=255, null=True) email = models.EmailField("email address", unique=True, null=True) is_active = models.BooleanField(default=True) is_superuser = None is_admin = None is_verified = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) objects = UserManager() def __str__(self): return self.name or self.email def is_admin(self): return self.groups.filter(name=AuthGroup.ADMIN.name).exists() This is the request body which is coming from user. { "name": "test4", "email": "test4@example.com", "is_active": true, "roles": [ "ADMIN", "OPERATOR" ] } So … -

Django: select_related query is ignored and the related queries are still executed

The first one is the join, but then there are 20+ other where each menu item is retrieved by id. Why isn't this working? -
Django customer user model and connexion
Hello, I'm developing a shop with Django [3.2] I would like to develop a login system for my customers so that they can see their invoices, pay online. I'm looking for documentation on how to manage their password but each time I come across back office user management. I obviously don't want my clients to have access to the back office. Should we make entries in the back office user table for front-end users (customers) and give them no right or should we develop a custom system. Are there things planned in Django for my case?

Setting up a working environment and using Django for Python on a Mac
I'm very new to programming especially on a Mac (only started using the terminal today). I need to set up python on this new Mac and setup virtual environments, then use Django to create simple Journal App. I have tried following various guides however I seem to struggle whenever I am asked to edit files as I don't know which files to edit, what their path is etc. I am using zsh not bash which makes a lot of guides redundant and I am using my work MacBook so I cannot change some of those settings. I have installed python 3.10 however my terminal still wants to use the default 2.7 which it had already, I have also installed honeybees, pip, Django, and some various other things these guides have instructed me to do. However I have no idea how this pathing stuff works and every time I try to use Django it essentially just doesn't recognise that I Have it installed. What I'm really asking for is a step by step guide to setting up Python and Working environments, (bearing in mind I'm unclear on how the pathing works) and then to use Django frameworks.

Creating a field in a model that allows multiple entries that is saved to the DB incrementally
I have a model called Handoff, users create a new handoff everyday and will add notes to this handoff to pass over to the next shift. I need a field that can capture user entry and save to the DB, but this field needs to be able to write to the database iteratively. For context, the user will add a new note each time they have something to add to the handoff and this needs to be written to the DB individually (for example, if the field was called new_note, the data should write to the DB and each new note will be saved as new_note_1). These notes will then be collated in a table to present to the next shift during a handoff. What are the best methods for approaching this? -

How can I display a dynamic list of saved items in my application
