Django - is it required to use/overwrite form_valid() when using CBV?

Why is it required to overwrite it since Django is already doing that? Is a missing piece of information and I would appreciate if anyone could provide a relevant answer. Thanks! -

Django Import Export Inline
I got stuck when using it in inline model class Order(models.Model): customer = models.ForeignKey(User, on_delete=models.CASCADE, default=None, null=True, blank=False) courier = models.ForeignKey(Courier, on_delete=models.CASCADE, null=True, blank=False) shipping_charges = models.DecimalField(max_digits=25, decimal_places=2, null=True, blank=False) payment = models.CharField(max_length=100, choices=Payment, default='Bank Transfer', null=True, blank=False) status = models.CharField(max_length=100, choices=Status, default='Pending', null=True, blank=False) date_added = models.DateField(auto_now_add=False, null=True, blank=False) date_modified = models.DateField(auto_now=True, null=True, blank=True) def __str__(self): return 'by ' + str(self.customer) class Item(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE, null=True, blank=False) product = models.ForeignKey(Product, on_delete=models.CASCADE, null=True, blank=False) attribute = models.ForeignKey(Attribute, on_delete=models.CASCADE, null=True, blank=True) quantity = models.DecimalField(max_digits=5, decimal_places=2, null=True, blank=False) total = models.DecimalField(max_digits=25, decimal_places=2, null=True, blank=False) def __str__(self): return self.product.title I used compactinline with jet admin, when i trying to export data for ITEM got blank data, i want export product too in each order detail. This my export class class OrderExport(resources.ModelResource): date_added = Field(attribute='date_added', column_name='Date') customer = Field(attribute='customer', column_name='Customer') product = fields.Field(attribute='product', column_name='Product', widget=ForeignKeyWidget(Item, 'product')) courier = Field(attribute='courier', column_name='Courier') shipping_charges = Field(attribute='shipping_charges', column_name='Shipping Charges') payment = Field(attribute='payment', column_name='Payment') status = Field(attribute='status', column_name='Status') class Meta: model = Order fields = ('date_added', 'customer', 'product', 'courier', 'shipping_charges', 'payment', 'status')
