如何将多个整数传递给 Django 列表中存在的 ManyToMany 字段

Question

我想将此产品添加到两个类别中，如何操作

class Category(models.Model):
    name = models.CharField(max_length=500)
    image = models.ImageField(upload_to='categories', default='default.png')

class Products(models.Model):
    name = models.CharField(max_length=500)
    category_id = models.ManyToManyField(Category, default='')

category_id = [4, 6]

 product, created = Products.objects.get_or_create(name =data['Casual Red Shirt'], 
                              product.category_id.add()

Answer 1

试试这个

category_id = [4, 6]
product, created  = Products.objects.get_or_create(name =data['Casual Red Shirt'], 

product.category_id.add(* category_id)
