How to only show related objects in Django Admin screens

I have an app where I want administrators to be able to create events via the admin view. I have members, who will have multiple cars and attend multiple meets. I want to record which vehicle they used at a meet.

In the django admin view for a member, I can manage their cars successfully and only cars belonging to that member show up in the inline on the Member Admin page, but when attempting to manage meets, all cars are listed, not only cars belonging to that member.

I want the same list of cars from the CarInline to appear in the MeetInline - i.e. cars registered to the member. Any ideas how to achieve this?

I think that the issue is that the Meet model has a ManyToMany relationship with the Car model but wasn't sure how else to model this.

models.py

class Member(models.model):
	member_number = models.CharField(primary_key=True, max_length=30)
	is_active = models.BooleanField(default=True)

class Car(models.model) 
	member = models.ForeignKey(Member)
	registration = models.CharField(max_length=80)


class Meet(models.model)
	meet_date = models.DateTimeField()
	member = models.ForeignKey(Member)
	car = models.ManyToManyField(Car)

admin.py

class CarInline(admin.TabularInline):
    model = Car
    extra = 0
    fields = ["registration"]

class MeetInline(admin.TabularInline):
    model = Meet
    extra = 0
    fields =["meet_date", "car"]

class MemberAdmin(admin.ModelAdmin):
    list_filter = [
        "is_active"
    ]
    search_fields = ["member_number"]
    fieldsets = [
        (None, {"fields": ["member_number", "is_active"]}),
    ]
    inlines = [CarInline, MeetInline]

from django import forms
from django.contrib import admin

from .models import Member, Car, Meet


class CarInline(admin.TabularInline):
    model = Car
    extra = 0
    fields = ["registration"]


class MeetInline(admin.TabularInline):
    model = Meet
    extra = 0
    fields = ["meet_date", "car"]

    def formfield_for_manytomany(self, db_field, request, **kwargs):
        """
        Override the default formfield for the 'car' field to only show cars
        belonging to the current member.
        """
        formfield = super().formfield_for_manytomany(db_field, request, **kwargs)

        if db_field.name == "car":
            member_pk = request.resolver_match.kwargs.get("object_id") // here i have used object_id as pk please change it according to what your pk name is
            if member_pk:
                member = Member.objects.get(pk=member_pk)
                formfield.queryset = member.car_set.all()

        return formfield


class MemberAdmin(admin.ModelAdmin):
    list_filter = ["is_active"]
    search_fields = ["member_number"]
    fieldsets = [(None, {"fields": ["member_number", "is_active"]}),]
    inlines = [CarInline, MeetInline]


admin.site.register(Member, MemberAdmin)
