How to pass a list of dictionaries in a function?
I am working on a teacher grading system in Django. I want functionality in which there is some entry like subject id and student's marks from the frontend. My app on the backend takes these two-parameter and creates a list of dictionaries with subject id and marks and pass it on another function and that function will sum up all the marks and give me a total and next average and percentage etc. But right now, I am stuck with total only so, when I pass this list of dictionaries in a function it gives me an error. class Marks_entry: def marks_entry(subject_id, marks): try: subject_id = int(input(f'Enter subject id: ')) marks=int(input(f'Enter marks: ')) except ValueError: print(f'You can only try integers:') marks_entry=[] marks_entry.append({ "subject_id": subject_id, "marks": marks }) marks_calculation = marks_calculation(marks_entry) return marks_calculation def marks_calculation(marks_entry): total = sum(item['marks'] for item in marks_entry) return total marks=0 subject_id= 0 b= Marks_entry b.marks_calculation(marks, subject_id) error is: Enter subject id: 1003 Enter marks: 58 Traceback (most recent call last): File "c:\Users\Lenovo\Documents\TGS\controller.py", line 53, in <module> b.marks_entry(subject_id, marks) File "c:\Users\Lenovo\Documents\TGS\controller.py", line 43, in marks_entry marks_calculation = marks_calculation(marks_entry) UnboundLocalError: local variable 'marks_calculation' referenced before assignment -
Django / GraphQL -- 2 types have fields that are referencing each other causes a crash
I have 2 graphql types that each have fields that refer to the other. There is an error because one of the types has not been declared when the first one is read. The issue is that the type should be instantiated before using it in a field. But since the two types refer to each other, One is always being referred to before it has been instantiated. Any ideas on how to solve? Here is a link to the parts of the code that are relevant: https://gist.github.com/olivermontalbano/ce8db9fd62619b983ed68b6933ff7e64 -
Django ManyToManyField with through -- how can I not lose data not selected in the QuerySet?
Django Newbie here. I have some trouble with a ManyToMany relationship and a through field. I am trying to create a tool where staff members can apply for shifts on events (Bar, entry control, etc.). Therefore I created a Staff object (this is the person with all her roles etc.) and linked it by ManyToManyField to a ScheduledShift object (which contains event date, time and duties). I want to be able to present each day as a view to the user where he/she can just tick the shifts he/she is available that day. This works and it also writes the correct data (i.e. the staff id and the shift id for all the shifts he/she ticked) for that day into the "through" table (StaffShift object). The relevant code looks like this: models.py class Staff(models.Model): ... shifts = models.ManyToManyField(ScheduledEventShift, through='StaffShift') class StaffShift(models.Model): staff = models.ForeignKey(Staff, on_delete=models.CASCADE) shift = models.ForeignKey(ScheduledEventShift, on_delete=models.CASCADE) views.py class StaffShiftUpdateView(ObjectUpdateView): model = Staff ... def get_form(self, form_class=None): form = super().get_form(form_class=self.form_class) day = datetime(self.kwargs.get('year'), self.kwargs.get('month'), self.kwargs.get('day')) form.fields['shifts'].queryset = ScheduledEventShift.objects.filter( event__event_date=day).order_by('event__event_date') return form ('event' is a property in the ScheduledEventShift object) My problem is that by writing those ids into the through table, all other rows for that user that … -

How to differentiate between user inactivity and continous http request in django?
I would like to logout the session if there is no activity on web application from user. Currently, I have implemented custom middleware to logout for configured time interval. In my application, there is need to do continuous polling every 2 seconds. But, in my custom middleware class "def process_request(self, request)" gets called everytime when polling is getting executed. So, the session never gets logout, as this polling also it is considering as user activity. Now, how do I differentiate between user inactivity & polling? Code: from django.utils.deprecation import MiddlewareMixin from django.contrib.auth import logout from django.contrib import messages from datetime import datetime, timedelta from django.contrib import auth from django.conf import settings class CustomMiddleware(MiddlewareMixin): def process_request(self, request): if not request.user.is_authenticated : #Can't log out if not logged in return try: if datetime.now() - request.session['last_touch'] > timedelta( 0, settings.AUTO_LOGOUT_DELAY * 60, 0): auth.logout(request) del request.session['last_touch'] return except KeyError: pass request.session['last_touch'] = datetime.now() settings.py: SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer' AUTO_LOGOUT_DELAY = 1 -

'server{ listen 443; server_name class.domain.com; root /var/www/html/; index index.html; location /static/ { try_files $uri $uri/ /index.html; } location ~ ^/ { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } }' -
