Страница Django DetailView - встроенный набор форм не сохраняется в SQL

Я пытаюсь реализовать Django inline formset в DetailView. Согласно документации гораздо лучше разделить представления Detail и Form и свести их вместе в третьем представлении, что я и сделал. Моя форма видна в файле шаблона, но после отправки ничего не происходит. Она корректно возвращается в представление подробной информации о продукте, но никакие данные не сохраняются в SQL.

Можете, пожалуйста, сообщить мне, что я делаю неправильно?

models.py

class Product(models.Model):
    title = models.CharField('title', max_length=400, blank=False, null=False, help_text='max 400 characters', default='')

class CERequest(models.Model):
    author = models.CharField(max_length=255, blank=True, null=True)
    related_component = models.ForeignKey(CostCalculator, on_delete=models.CASCADE, blank=True, null=True, default=1)
    number_of_units = models.IntegerField(default=0)
    related_product = models.ForeignKey(Product, on_delete=models.CASCADE, null=True, blank=True, related_name='related_product_ce_request')
    created = models.DateTimeField(default=timezone.now)
    total_price = models.IntegerField(verbose_name='Price (€)', default=0, blank=True, null=True)

forms.py

class CalculatorFormProduct(forms.ModelForm):
    author = forms.CharField(widget = forms.HiddenInput(), required = False)
    number_of_units = forms.IntegerField(help_text='Only numeric values are allowed.', min_value=0)
    total_price = forms.IntegerField(widget = forms.HiddenInput(), required = False)
    created = forms.DateTimeField(widget = forms.HiddenInput(), required = False)
  
    
    class Meta: 
        model = CERequest
        fields = ('author', 'created', 'related_product', 'related_component', 'number_of_units')
