django-restframework detailview問題

Question

使用django-rest-framework我試圖實現一些簡單的API。

以下是驗證碼。我對着

問題是：

1. 的產品/（P \ d +）/從未執行ProductsDetailView。我始終獲得所有產品列表，而不考慮URL中的ID。
2. 但是，當我從URL中刪除產品/時，我收到單一產品作爲響應。但是，不幸的是現在我不能擁有所有的產品，因爲該API的URL被刪除。

我不知道我正在做什麼錯，因爲這個問題正在發生。請幫幫我。

MODEL：

class Product(models.Model): 
product_owner = models.ForeignKey(User, verbose_name='User') 
product_imported_via = models.CharField(max_length=200, default="0", null=False, choices=PRODUCT_IMPORT_SOURCE, 
             verbose_name='Source of import') 
product_title = models.CharField(max_length=100, null=False, verbose_name='Product title') 
product_description = models.TextField(max_length=250, verbose_name='Product description') 
product_qty = models.IntegerField(verbose_name='Quantity') 
product_mrp = models.DecimalField(max_digits=12, decimal_places=2, verbose_name='Maximum retail price') 
product_offer_price = models.DecimalField(max_digits=12, decimal_places=2, verbose_name='Selling price') 
_product_discount_amount = models.FloatField(null=True, editable=False, verbose_name='Discount amount', 
              db_column='product_discount_amount') 
_product_discount_percentage = models.IntegerField(null=True, editable=False, verbose_name='Disount percentage', 
                db_column='product_discount_percentage') 
product_sku = models.CharField(max_length=100, null=False, unique=True, verbose_name='SKU',help_text='Enter Product Stock Keeping Unit') 
product_barcode = models.CharField(max_length=100, null=False, verbose_name='Barcode') 
archive = models.BooleanField(default=False) 

串行器：

from rest_framework import serializers 
from .models import Product 

class ProductsSerializer(serializers.ModelSerializer): 

class Meta: 
    model = Product 
    fields = ('id','product_title', 'product_description', 'product_qty', 'product_mrp', 
       'product_offer_price','product_discount_amount','product_discount_percentage', 
       'product_sku','product_barcode')

from rest_framework.views import APIView 
from rest_framework.response import Response 
from .models import Product 
from .serializers import ProductsSerializer 
from django.http import Http404 

#Create your views here. 
class ProductsListView(APIView): 

def get(self, request): 

    print('In update list') 
    updates = Product.objects.all() 
    serializer = ProductsSerializer(updates, many=True) 
    return Response(serializer.data) 


class ProductsDetailView(APIView): 

def get_object(self, pk): 
    try: 
     return Product.objects.get(pk=pk) 
    except Product.DoesNotExist: 
     raise Http404 

def get(self, request, pk): 
    update = self.get_object(pk) 
    serializer = ProductsSerializer(update) 
    return Response(serializer.data)

from products.views import ProductsListView, ProductsDetailView 
urlpatterns = [ 
       url(r'^admin/', admin.site.urls), 
       url(r'^products/', ProductsListView.as_view()), 
       url(r'^products/(?P<pk>\d+)/', ProductsDetailView.as_view()), 
      ]

有沒有使用「$」來表示路由字符串的結束理由嗎？

除此之外，如果你打算做的是擁有一個列表視圖，然後是具有ID的每個產品的單獨視圖，則應該重新訪問Django路由器文檔，因爲您不需要兩個路由語句做到這一點。
