Question

我有一个“类别”，“子类别”和“产品”模型。与其查看每个类别，子类别和产品，不如我想浏览要使用righ模型填充的模板。

models.py

class Category(models.Model):
    category_title = models.CharField(max_length=200)
    category_image = models.ImageField(upload_to="category")
    category_description = models.TextField()
    category_slug = models.SlugField(max_length=200, default=1)

    class Meta:
        verbose_name_plural = "Categories"

    def __str__(self):
        return self.category_title 


class Subcategory(models.Model):
    subcategory_title = models.CharField(max_length=200)
    subcategory_image = models.ImageField()
    subcategory_category = models.ForeignKey(
        Category, default=1, verbose_name="Category", on_delete=models.SET_DEFAULT)

    class Meta:
        verbose_name_plural = "Subcategories"

    def __str__(self):
        return self.subcategory_title


class Product(models.Model):
    product_title = models.CharField(max_length=200)
    product_image = models.ImageField()
    product_base_price = models.DecimalField(max_digits=12, decimal_places=2)
    product_addons = models.CharField(max_length=200, blank=True)
    product_description = models.TextField()
    product_date_added = models.DateTimeField(default=datetime.now, blank=True)
    product_slug = models.SlugField(max_length=200, default=1)
    product_subcategory = models.ForeignKey(
    Subcategory, default=1, verbose_name="Subcategories", on_delete=models.SET_DEFAULT)
    product_available = models.BooleanField(default=True)

Answer 1

要列出所有具有特定产品链接的产品

以下是产品模型的示例view，url和template。请用您的应用名称替换myapp。

定义视图：

# views.py
from django.views.generic import ListView
from django.shortcuts import render
from .models import Product

class ProductList(ListView):
    model = Product

def productdetail(request,id):
    product = Product.objects.get(id = id)
    return render(request, 'myapp/product.html', {'product': product})

最后将该视图链接到您的网址中

# urls.py
from django.urls import path
from myapp.views import ProductList, productdetail

urlpatterns = [
    path('products/', ProductList.as_view()),
    path('products/<int:pk>/', productdetail, name='productdetail'),
]

创建一个模板，以列出以下位置的产品：/path/to/project/myapp/templates/myapp/products_list.html

{% extends "base.html" %}

{% block content %}
    <h2>Products</h2>
    <ul>
        {% for product in object_list %}
            <li><a href="{% url 'productdetail' product.id %}">{{ product.product_title }} </a></li>
        {% endfor %}
    </ul>
{% endblock %}

创建一个模板以显示特定的产品：/path/to/project/myapp/templates/myapp/product.html ::

{% extends "base.html" %}

{% block content %}
    <h2>Product</h2>
    {{product.product_title}}
{% endblock %}

Answer 2

    product_created_on = models.DateTimeField(auto_now_add=True)

我有答案，只需使用DateTimeField()

在Django中为单个产品创建页面
