我自己的購物籃

Question

如何添加我的Item至Basket？

class Item(models.Model): 
    name = models.CharField(max_length=50) 
    category = models.ManyToManyField(Category) 
    price = models.DecimalField(max_digits=5, decimal_places=2) 

    def __unicode__(self): 
     return self.name 


class Basket(models.Model): 
    owner = models.ForeignKey(User, related_name='user_basket', verbose_name='Owner') 
    name = models.CharField("Basket name", max_length=120) 
    items = models.ManyToManyField('Item', blank=True, null=True) 

我嘗試：

def add_item_to_basket(request, product_id): 
    if request.method == 'GET': 
     form = BasketForm(request.GET) 
     if form.is_valid(): 
      quantity = form.cleaned_data['quantity'] 
      items = Item.objects.get(id=item_id) 
      .........? 

Answer 1

your_basket.items.add(your_item)
