如何在 django 的上下文处理器文件中检查登录用户

Question

I am using context processors for showing total products in cart and other details in my project's header and footer. This is my file for context processors file "custom_context.py"

from models import Event, Ticket_Cart_details

def get_base_content(request):
    music_events = Event.objects.all().filter(category='music', status = True).values('id','event_title').order_by('-id')[:4]
    sports_events = Event.objects.all().filter(category='sports', status = True).values('id','event_title').order_by('-id')[:4]
    experience_events = Event.objects.all().filter(category='experience', status = True).values('id','event_title').order_by('-id')[:4]
    lifestyle_events = Event.objects.all().filter(category='lifestyle', status = True).values('id','event_title').order_by('-id')[:4]

The above code does not contain any information about logged in user now i have to write a code in which i have to get data of logged in user.

from models import Event, Ticket_Cart_details

def get_base_content(request):
    music_events = Event.objects.all().filter(category='music', status = True).values('id','event_title').order_by('-id')[:4]
    sports_events = Event.objects.all().filter(category='sports', status = True).values('id','event_title').order_by('-id')[:4]
    experience_events = Event.objects.all().filter(category='experience', status = True).values('id','event_title').order_by('-id')[:4]
    lifestyle_events = Event.objects.all().filter(category='lifestyle', status = True).values('id','event_title').order_by('-id')[:4]

    if request.user.is_authenticated():
        current_cart_products = Ticket_Cart_details.objects.all().filter(user_id=request.user.id, session_id=request.session.session_key)
    current_cart_products = Ticket_Cart_details.objects.all().filter(session_id=request.session.session_key)

In the above code "request" will not work, so how can i get records of logged in user using this

You are using request well, but when you work with context processors, you have to return all the data that you want. For example:

def get_base_content(request):
    music_events = Event.objects.all().filter(category='music', status=True).values('id','event_title').order_by('-id')[:4]
    sports_events = Event.objects.all().filter(category='sports', status=True).values('id','event_title').order_by('-id')[:4]
    return {"music_events": music_events,
            "sports_events": sports_events ,
            }

Additionally, for the problems with user not allowed or not logged in, you have to handle it with a anonymous data or something like this.

def get_base_content(request):
    if not request.user:
        music_events = 'none'
        sports_events = 'none'
