from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField()
    price = models.DecimalField(max_digits=8, decimal_places=2)
    # 其他属性...

from django.db import models
from django.contrib.auth.models import User

class Favorites(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    products = models.ManyToManyField(Product)
    # 其他属性...

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from .models import Product, Favorites

@login_required
def add_to_favorites(request, product_id):
    product = Product.objects.get(id=product_id)
    favorites, created = Favorites.objects.get_or_create(user=request.user)
    favorites.products.add(product)
    return redirect('favorites')

@login_required
def remove_from_favorites(request, product_id):
    product = Product.objects.get(id=product_id)
    favorites = Favorites.objects.get(user=request.user)
    favorites.products.remove(product)
    return redirect('favorites')

from django.urls import path
from .views import add_to_favorites, remove_from_favorites

urlpatterns = [
    path('add/<int:product_id>/', add_to_favorites, name='add_to_favorites'),
    path('remove/<int:product_id>/', remove_from_favorites, name='remove_from_favorites'),
    # 其他URL配置...
]
