Why is a single product page not loading in Django project-CodePudding

I am trying to make an ecommerce project and I already set up products page, but It should load a product description page after goint to api/products/2 page, example(2 is a product id). views.py:

@api_view(['GET'])
def getProduct(request, pk):
    product = None
    for i in products:
        if i['_id'] == pk:
            product = i
            break

    return Response(product)

urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.getRoutes, name="routes"),
    path('products/', views.getProducts, name="products"),
    path('prodcucts/<str:pk>/', views.getProduct, name="product"),
]

I already tried int:pk instead of str:pk

CodePudding user response：

At first check whether you need <str:pk> or <int:pk> as "2" and 2 is treated differently in Python.

Then try this:

@api_view(['GET'])
def getProduct(request, pk):
    product = ""

    for i in products:
        if i['_id'] == pk:
            product = i

    return Response(Product)

Edit:

The path name path('prodcucts/<str:pk>/'... seems incorrect kindly check it.

CodePudding user response：

You are declaring products = None and then you iterate with a for loop through products. That results in iterating over None

Try to go for something like this:

from .your_model_module import Product

@api_view(['GET'])
def getProduct(request, pk):
    product = Product.objects.get(id=pk)

    return Response(product)

First you need to import your model. Then you do a get query within all these Product objects that are stored in your database. The get query will result in an error (if not found matching object or when multiple objects are found) or will return one object.

If you want to allow that multiple objects are getting found, replace get with filter lookup.

Also stick to your int:pk
