كيفية برمجة موقع مراجعة منتجات باستخدام Python Django (دليل شامل)

Python

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

class Product(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()
    price = models.DecimalField(max_digits=10, decimal_places=2)
    image = models.ImageField(upload_to='products/', blank=True, null=True)
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.name

class Review(models.Model):
    product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='reviews')
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    rating = models.IntegerField(choices=[(i, str(i)) for i in range(1, 6)])
    comment = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f"Review by {self.user.username} for {self.product.name}"

Python

from django.shortcuts import render, get_object_or_404, redirect
from .models import Product, Review
from .forms import ReviewForm
from django.contrib.auth.decorators import login_required

def product_list(request):
    products = Product.objects.all()
    return render(request, 'reviews/product_list.html', {'products': products})

def product_detail(request, product_id):
    product = get_object_or_404(Product, pk=product_id)
    form = ReviewForm()
    return render(request, 'reviews/product_detail.html', {'product': product, 'form': form})

@login_required
def add_review(request, product_id):
    product = get_object_or_404(Product, pk=product_id)
    if request.method == 'POST':
        form = ReviewForm(request.POST)
        if form.is_valid():
            review = form.save(commit=False)
            review.product = product
            review.user = request.user
            review.save()
            return redirect('product_detail', product_id=product.id)
    else:
        form = ReviewForm()
    return render(request, 'reviews/product_detail.html', {'product': product, 'form': form})

Python

from django.contrib import admin
from .models import Product, Review

class ReviewInline(admin.TabularInline):
    model = Review
    extra = 1

class ProductAdmin(admin.ModelAdmin):
    list_display = ('name', 'price', 'created_at')
    inlines = [ReviewInline]

class ReviewAdmin(admin.ModelAdmin):
    list_display = ('product', 'user', 'rating', 'created_at')
    list_filter = ('rating', 'product')
    search_fields = ('comment', 'product__name', 'user__username')

admin.site.register(Product, ProductAdmin)
admin.site.register(Review, ReviewAdmin)
