在 django 导入导出时如何使用外键中的数据值

Question

我想问从Django导入导出库中的csv文件导入数据时如何使用外键的值。？ 在此先感谢，我遇到的主要问题是我必须导入一个 csv 文件，其中包含 model 的数据，其中包含外键。 整体架构是这样的：主要的 model 是：

class Reservation(models.Model):
    company = models.ForeignKey(company_models.CompanyProfileModel, null=True, blank=True, on_delete=models.CASCADE)
    reservation_status = models.CharField(max_length=35, null=True, blank=True, choices=status_types,default=REQUESTED)
    reservation_no = models.CharField(max_length=40, null=True, blank=True)
    client = models.ForeignKey(PersonalClientProfileModel, null=True, blank=True, on_delete=models.SET_NULL)
    service_type = models.ForeignKey(setting_models.ServiceType, on_delete=models.SET_NULL, null=True, blank=True)
    sales_tax = models.ForeignKey('setting.SalesTax', on_delete=models.CASCADE, null=True, blank=True)
    charge_by = models.CharField(max_length=50, choices=charge_by, null=True, blank=True)
    pay_by = models.CharField(max_length=50, choices=payment_type, null=True, blank=True,verbose_name='Payment Method')
    vehicle_type = models.ForeignKey(setting_models.VehicleType, on_delete=models.SET_NULL, null=True, blank=True)
    vehicle = models.ForeignKey(Vehicle, null=True, blank=True, on_delete=models.SET_NULL)
    driver = models.ForeignKey(EmployeeProfileModel, null=True, blank=True, on_delete=models.SET_NULL)
    accepted_by_driver = models.BooleanField(null=True, blank=True, default=False)
    pickup_address = models.ForeignKey(GeoAddress, on_delete=models.SET_NULL, related_name='pickup_address',null=True,blank=True)
    destination_address = models.ForeignKey(GeoAddress, on_delete=models.SET_NULL, related_name='destination_address',null=True, blank=True)
    # pickup_address = models.CharField(max_length=200, null=True, blank=True)
    # destination_address = models.CharField(max_length=200, null=True, blank=True)
    pick_up_date = models.DateField(blank=True, null=True)
    pick_up_time = models.TimeField(blank=True, null=True)
    distance_in_miles = models.FloatField(null=True, blank=True, default=0.0)
    distance_covered_in_ride = models.FloatField(null=True, blank=True, default=0.0)
    total_hours = models.CharField(max_length=10, null=True, blank=True)
    from_date = models.DateField(null=True, blank=True)
    to_date = models.DateField(null=True, blank=True)
    no_of_days = models.IntegerField(null=True, blank=True, default=0)
    rate_per_mile = models.FloatField(null=True, blank=True, default=0.0)
    rate_per_day = models.FloatField(null=True, blank=True, default=0.0)
    additional_passenger_charge = models.FloatField(null=True, blank=True, default=0.0)
    additional_luggage_charge = models.FloatField(null=True, blank=True, default=0.0)
    additional_stops_charge = models.FloatField(null=True, blank=True, default=0.0)
    stops_between_ride = models.IntegerField(null=True, blank=True, default=0)
    stops_address = models.ManyToManyField(GeoAddress, blank=True)
    passenger_quantity = models.IntegerField(blank=True, null=True, default=1)
    luggage_bags_quantity = models.IntegerField(blank=True, null=True, default=0)
    car_seats = models.IntegerField(blank=True, null=True)
    client_notes = models.CharField(max_length=150, null=True, blank=True)
    driver_notes = models.CharField(max_length=200, blank=True, null=True)
    discount_percentage = models.FloatField(null=True, blank=True, max_length=100, default=0.0)
    gratuity_percentage = models.FloatField(null=True, blank=True, max_length=100, default=0.0)
    fuel_Surcharge_percentage = models.FloatField(null=True, blank=True, max_length=100, default=0.0)
    sales_tax_percentage = models.FloatField(null=True, blank=True, default=0.0)
    tolls = models.FloatField(null=True, blank=True, default=0.0)
    meet_and_greet = models.FloatField(null=True, blank=True, default=0.0)
    duration = models.CharField(max_length=10, choices=get_duration_choices(25), null=True, blank=True)
    base_fare = models.FloatField(blank=True, null=True, default=0.0)
    deposit_amount = models.FloatField(null=True, blank=True, default=0.0)
    deposit_type = models.CharField(max_length=100, choices=deposit_types, null=True, blank=True)
    balance_fare = models.FloatField(null=True, blank=True, default=0.0)
    balance_paid = models.BooleanField(null=True, blank=True, default=False)
    total_fare = models.FloatField(blank=True, null=True, default=0.0)
    cheque_no = models.CharField(max_length=40, null=True, blank=True)
    is_duplicated = models.BooleanField(null=True, blank=True, default=False)
    sales_tax_payment = models.ForeignKey(Accounting.Tax.models.SalesTaxPayment, on_delete=models.SET_NULL, null=True,blank=True)
    airport = models.CharField(max_length=100, null=True, blank=True)
    airline = models.CharField(max_length=100, null=True, blank=True)
    flight_num = models.CharField(max_length=100, null=True, blank=True)
    created_at = models.DateTimeField(auto_now_add=True, null=True)
    updated_at = models.DateField(auto_now=True, null=True)

在这个**公司字段与 CompanyProfileModel 和 ForeignKey 相关然后在 CompanyProfileModel 我们有与 UserProfileModel 相关的用户配置文件和 OneToOne 属性然后在用户配置文件中我们有与用户 model 相关的用户与外键**

这是我的资源 Function：

class ReservationResourceForImport(resources.ModelResource):
    class Meta:
        model = reservation_models.Reservation
        exclude = ['distance_in_miles', 'total_hours', 'from_date', 'to_date', 'no_of_days', 'rate_per_mile',
                   'rate_per_day', 'additional_passenger_charge', 'additional_luggage_charge',
                   'additional_stops_charge', 'stops_between_ride', 'stops_address', 'discount_percentage',
                   'gratuity_percentage', 'fuel_Surcharge_percentage', 'sales_tax_percentage', 'tolls',
                   'meet_and_greet', 'duration', 'base_fare', 'deposit_amount', 'deposit_type', 'balance_fare',
                   'balance_paid', 'cheque_no', 'accepted_by_driver', 'distance_covered_in_ride', 'car_seats',
                   'is_duplicated', 'sales_tax_payment', 'created_at', 'updated_at',
                   "sales_tax",
                   "charge_by", "pay_by", 'client_notes', 'driver_notes']
        export_order = (
            "id", "company", "reservation_no", "client", "reservation_status",
            "pick_up_date", "pick_up_time",
            "pickup_address", "destination_address", "vehicle",
            "driver", "service_type", "vehicle_type", "passenger_quantity", "luggage_bags_quantity",
            "total_fare")

如果我使用外键 ID 导入 csv 中的数据，一切顺利：

ID,Company,Reservation_data, Client 3, 4, 23/09/2022, 2 但我想导入具有数据名称的数据，例如：ID, Company, Reservation_data, Client** 3, company_name, 23/09 /2022，客户名称**

和 company_name 将通过：

公司 > 用户配置文件 > 用户 > 用户名和客户端：客户端 > 用户配置文件 > 用户 > 用户名

请给出一个解决方案，如何在 django 导入导出数据时输入字段的用户名

问候，
