無法將關鍵字'可用'解析爲字段。選項包括：ID

Question

這是我的觀點的相關部分

def product_list(request, category_slug=None): 
    category = None 
    categories = Category.objects.all() 
    products = Product.objects.filter(available=True) 
    if category_slug: 
     category = get_object_or_404(Category, slug=category_slug) 
     products = products.filter(category=category) 
    return render(request,'list.html',{'category': category, 
             'categories': categories,'products': products}) 

這是我的模型的相關部分，我認爲這個問題是從這裏

class Product(models.Model): 
    category = models.ForeignKey(Category, related_name='products') 
    name = models.CharField(max_length=200, db_index=True) 
    slug = models.SlugField(max_length=200, db_index=True) 
    image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True) 
    description = models.TextField(blank=True) 
    price = models.DecimalField(max_digits=10, decimal_places=2) 
    stock = models.PositiveIntegerField() 
    available = models.BooleanField(default=True) 
    created = models.DateTimeField(auto_now_add=True) 
    updated = models.DateTimeField(auto_now=True) 

    class Meta: 
     ordering = ('name',) 
     index_together = (('id', 'slug'),) 

    def __str__(self): 
     return self.name

您是否爲模型進行遷移？如果是這樣，你是否遷移遷移？
