我正在使用 Vue 和 Django 来做这个项目,但是当我运行我的代码时,我不断收到此错误
"Failed to load resource: the server responded with a status of 500 (Internal Server Error) 127.0.0.1:8000/api/v1/products/winter/yellow-jacket-with-no-zipper:1"
我不断重新加载并等待了 30 分钟这个错误才消失,但它不断出现。 我不知道我的javascript是否有问题,因为我运行vue项目时没有任何错误。
这是我认为有问题的代码。
后端:
产品包中的urls.py模块:
from django.urls import path, include from product import views urlpatterns = [ path('latest-products/', views.LatestProductsList.as_view()), path('products/<slug:category_slug>/<slug:product_slug>', views.ProductDetail.as_view()), ]
前端:
Product.vue脚本:
<template> <div class="page-product"> <div class="columns is-multiline"> <div class="column is-9"> <figure class="image mb-6"> <img v-bind:src="product.get_image"> </figure> <h1 class="title">{{ product.name }}</h1> <p>{{ product.description }}</p> </div> <div class="column is-3"> <h2 class="subtitle">Information</h2> <p>Price: <strong>{{ product.price }}</strong></p> <div class="field has-addons mt-6"> <div class="control"> <input type="number" class="input" min="1" v-model="quantity"> </div> <div class="control"> <a class="button is-dark">Add to Carts</a> </div> </div> </div> </div> </div> </template> <script> import axios from 'axios' export default { name: 'Product', data() { return { product: {}, quantity: 1 } }, mounted() { this.getProduct() }, methods: { getProduct() { const category_slug = this.$route.params.category_slug const product_slug = this.$route.params.product_slug axios .get(`/api/v1/products/${category_slug}/${product_slug}`) .then(response => { this.product = response.data }) .catch(error => { console.log("error") }) } } } </script>
编辑:
经过一番修改,我认为问题是由产品包中的views.py模块引起的
from django.http import Http404 from rest_framework.views import APIView from rest_framework.response import Response from .models import Product from .serializers import ProductSerializer class LatestProductsList(APIView): def get(self, request, format=None): products = Product.objects.all()[0:4] serializer = ProductSerializer(products, many=True) return Response(serializer.data) #I think its this line of code class ProductDetail(APIView): def get_object(self, category_slug, product_slug): try: return Product.objects.filter(category_slug=category_slug).get(slug=product_slug) except Product.DoesNotExist: raise Http404 def get(self, request, category_slug, product_slug, format=None): product = self.get_object(category_slug, product_slug) serializer = ProductSerializer(product) return Response(serializer.data)
修改代码后,我发现我是对的。问题出在产品包中的views.py模块。可以在 ProductDetail 类中的 get_object 函数中看到。

问题是我在定义类别slug时需要添加另一个下划线/下划线(这个东西:_),所以
变成了
