here's my problem.I'm trying to create product variants which contain attribute values of the selected product. I'm trying to use JSONField to do that but I was wondering how I could dynamically display the fields in the form for creating new product variants.
Here is my models.py file:
class Product(models.Model) :
name = models.CharField(max_length=120)
price = models.DecimalField(max_digits=10, decimal_places=2)
image = models.ImageField(upload_to='products')
allow_variants = models.BooleanField(default=True)
product_attributes = models.ManyToManyField("attribute")
def __str__(self) :
return self.name
class Meta :
ordering = ("name",)
class Attribute(models.Model) :
name = models.CharField(max_length=120)
def __str__(self) :
return self.name
def get_all_attr_variants(self) :
variants = AttributeVariant.objects.filter(attribute__name=self.name)
return variants
class AttributeVariant(models.Model) :
name = models.CharField(max_length=120)
attribute = models.ForeignKey(Attribute, on_delete=models.CASCADE)
def __str__(self) :
return self.name
class Meta :
ordering = ('name',)
class ProductVariant(models.Model) :
product = models.ForeignKey(Product, on_delete=models.CASCADE)
name = models.CharField(max_length=120)
price = models.DecimalField(max_digits=10, decimal_places=2)
attributes = JSONField()
def __str__(self) :
return self.product.name + ": " + self.name
class Meta :
ordering = ("product.name", "name")
Please help me if you have any idea of how I could solve this problem!
Thanks
