Question

当我尝试访问产品型号的详细信息页面时，我收到了该错误。我在url文件中有slug字段，但似乎并不重要。

模型

class Product(models.Model):
    product_name= models.CharField(max_length=30, blank=False, null=False, verbose_name="the product name")
    product_slug= models.SlugField(max_length=30, blank=False, null=False, verbose_name="the product slug")
    product_excerpt= models.CharField(max_length=100, blank=False, null=False, verbose_name="product excerpt")
    def _set_product_code(self):
        product_code_temp = hashlib.sha224()
        product_hash = self.product_name
        product_hash = product_hash.encode('utf-8')
        product_code_temp.update(product_hash)
        return product_code_temp.hexdigest()[0:5]
product_code = property(_set_product_code)

查看

class ProductPage(DetailView):
    model = Product
    context_object_name = 'product'
    template_name="product.html"

地址

url(r'^product/(?P<product_slug>\w+)/(?P<product_code>\w+)/$', ProductPage.as_view(), name="product"),

任何人都可以查明我做错了什么吗？

Answer 1

在视图类上设置slug_field属性：

class ProductPage(DetailView):
    model = Product
    slug_field = 'product_slug'
    # etc

Answer 2

我想补充一点，get_object也适用于我们为主键提供不同查找参数的情况

示例，如果我想通过guid获取我的对象，我在URLConf中传递

def get_object(self):
    return Product.objects.get(guid=self.kwargs.get("guid"))

Answer 3

models.py

product_slug = models.SlugField(null=True, blank=True, help_text="Product slug field", db_column="product_slug",
                                verbose_name="slug product", error_messages={"required": "Enter the slug field"},
                                unique=True, )

使用下面的正则表达式为pk和slug写一行：

urls.py

url(r'(^products/(?P<pk>\d+)/$)|(^products/(?P<product_slug>\w+)/$)',ProductDetailView.as_view(), name='product-detail-view')

views.py

class ProductDetailView(DetailView):
     model = Products
     extra_context = {'title': 'products-detail-view'}
     pk_url_kwarg = 'pk'
     query_pk_and_slug = True
     slug_field = 'product_slug'
     slug_url_kwarg = 'product_slug'

必须使用对象pk或slug调用通用详细信息视图
