Hi guys,
I'd like to only be able to assign many ProcutImages to a Product, but only
ONE Image as a default image per product
(ProductImage.is_default_image=True).
I can't get this to work correnctly on Django 1.7 with a db.sqlite3: With
the code below I can only assign ONE Image to a Product. After that I get
the error "Product image with this Product und Is default image already
exists.".
Am I getting something wrong?
from django.db import models
class Product(models.Model):
title = models.CharField(max_length=255)
is_active = models.BooleanField(default=True)
class ProductImage(models.Model):
product = models.ForeignKey(Product)
image = models.ImageField(upload_to='products/images/')
is_default_image = models.BooleanField(default=False,null=False,blank=
False)
class Meta:
# A product can have multiple ProductImages, but only one of them
can be the "default"-image
unique_together = ('product', 'is_default_image')
I would be really thankful for some tips.
Kind regards
Thomas
