Hello. I am creating some simple queries using the Django framework. I have one app which it has 8 models in Here are my classes:
from django.db import models

# Create your models here.
class Category(models.Model):
    category_id = models.AutoField(primary_key=True)
    category_name = models.CharField(max_length=15)
    description = models.TextField(null=True, blank=True)

    def __str__(self):
        return f"ID: {self.category_id}, {self.category_name}"

class User(models.Model):
    user_id = models.AutoField(primary_key=True)
    first_name = models.CharField(max_length=10)
    last_name = models.CharField(max_length=20)
    mobile_number = models.CharField(max_length=11, unique=True)
    birth_date = models.DateField()
    country = models.CharField(max_length=15)
    city = models.CharField(max_length=15)
    region = models.CharField(max_length=15)
    address = models.TextField(null=True, blank=True)
    postal_code = models.CharField(max_length=10, unique=True)
    is_active = models.BooleanField(default=True)

    def __str__(self):
        return f"{self.first_name} {self.last_name}"

class Company(models.Model):
    company_id = models.AutoField(primary_key=True)
    company_name = models.CharField(max_length=30)

    def __str__(self):
        return f"ID: {self.company_id}, {self.company_name}"

class Customer(models.Model):
    customer_id = models.AutoField(primary_key=True)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    company = models.ForeignKey(Company, on_delete=models.CASCADE)
    contact_name = models.CharField(max_length=30, unique=True)
    contact_title = models.CharField(max_length=30, null=True)

    def __str__(self):
        return f"User {self.user.__str__()}  has ordered a ### from {} company.\n"

class Employee(models.Model):
    employee_id = models.AutoField(primary_key=True)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=30, null=True, blank=True)
    hire_date = models.DateField(null=True, blank=True)

    def __str__(self):
        return f"ID: {self.employee_id}, {self.user.__str__()} {self.title} {self.user.address}"

class Product(models.Model):
    product_id = models.AutoField(primary_key=True)
    product_name = models.CharField(max_length=40)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    unit_price = models.FloatField()

    def __str__(self):
        return f"ID: {self.product_id}, {self.product_name}: {self.unit_price}"

class Order(models.Model):
    order_id = models.AutoField(primary_key=True)
    customer = models.ForeignKey(Customer, on_delete=models.CASCADE)
    employee = models.ForeignKey(Employee, on_delete=models.CASCADE)
    order_time = models.DateTimeField(auto_now_add=True , auto_now=False)

        ('TR', 'Train'),
        ('AR', 'Airplane'),
        ('CA', 'Car'),
    freight = models.CharField(choices=FREIGHT_CHOICES, max_length=10)

    def __str__(self):
        return f"ID: {self.order_id}, Ordered by: {self.customer.user.__str__()}"

class OrderDetail(models.Model):
    order = models.ForeignKey(Order, on_delete=models.CASCADE)
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    unit_price = models.FloatField()
    quantity = models.SmallIntegerField(default=1)

    def __str__(self):
        return f"{self.order.customer.user.__str__()}/{self.product.product_name}:{self.unit_price * self.quantity}"

And I have a function in :
def each_customer_ordered_products(request):
    customer_ordered_products =  OrderDetail.objects.filter(order__customer__user__first_name = 'Aylin')
    return HttpResponse(customer_ordered_products)

Which shows only the products which have been ordered by Aylin. Now I want to create a new variable in this method like a dictionary or a json object
that can save every customer's first name as key and the ordered products as value and after running the application I want to see the whole of the dictionary not just for one of the customers.

What I have tried:

Unfortunately, I do not have any idea and I do not know how to map the orders to the customers and then create a variable and then pass it to HttpResponse or JsonResponse.I will be grateful for your help or advice.
