DJANGO complex modelling
- by SledgehammerPL
Hello.
I have such model now: receipt contains components. component contain product.
The difference between component and product is, that component has quantity and measure unit:
eg. component is 100g sugar - sugar is a product.
So I need to make lots of components to satisfy different recipes - 100g sugar is not equal 200g sugar
I wonder if I can remodel it to kick off components - in pure sql it's rather easy, but I'm trying to USE django - not making workarounds.
class Receipt(models.Model):
name = models.CharField(max_length=128)
(...)
components = models.ManyToManyField(Component)
class Component(models.Model):
quantity = models.FloatField(max_length=9)
unit = models.ForeignKey(Unit)
product = models.ForeignKey(Product)
class Product(models.Model):
name = models.CharField(max_length = 128)
TIA
