🧩 5-DARS: GENERIC API VIEWS BILAN ISHLASH

🎯 Dars Maqsadi

Bu darsda Generic API Views yordamida kod yozishni qisqartirish va professional API yaratishni o'rganasiz. Blog Platform loyihasini yaratish orqali barcha generic view'larni amaliyotda ko'rasiz.

Dars oxirida siz:

✅ Generic API Views nima ekanligini bilasiz
✅ Function-based views vs Generic views farqini tushunasiz
✅ Barcha generic view turlarini bilasiz (List, Create, Retrieve, Update, Delete)
✅ Mixins bilan ishlashni o'rganasiz
✅ Custom queryset va permission qo'shishni bilasiz
✅ Kod yozishni 10 barobar qisqartirishni o'rganasiz

💡 Nima Uchun Blog Platform?

Blog tizimi - Generic Views uchun eng yaxshi misol:

📝 Post yaratish, o'qish, yangilash, o'chirish
💬 Comments (izohlar) - nested relationship
🏷️ Categories - filtrlash
📊 Real-world use case

📚 Generic Views Nima?

Oddiy Kod vs Generic Views

Function-based view (30 qator):

@api_view(['GET', 'POST'])
def post_list(request):
    if request.method == 'GET':
        posts = Post.objects.all()
        serializer = PostSerializer(posts, many=True)
        return Response(serializer.data)
    
    elif request.method == 'POST':
        serializer = PostSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=201)
        return Response(serializer.errors, status=400)

Generic view (3 qator!):

class PostListCreateView(generics.ListCreateAPIView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

🌐 5. URL ROUTING

blog/urls.py:

from django.urls import path
from . import views

app_name = 'blog'

urlpatterns = [
    # ============ CATEGORIES ============
    # ListCreateAPIView - GET va POST
    path(
        'categories/',
        views.CategoryListCreateView.as_view(),
        name='category-list-create'
    ),
    
    # RetrieveUpdateDestroyAPIView - GET, PUT, PATCH, DELETE
    path(
        'categories/<int:pk>/',
        views.CategoryDetailView.as_view(),

blog_project/urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),

🛡️ 6. ADMIN PANEL

blog/admin.py:

from django.contrib import admin
from .models import Category, Post, Comment

@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
    list_display = ['id', 'name', 'slug']

        'title',
        'author',
        'category',
        'status',
        'views_count',
        'published_at'
    ]
    list_filter = ['status', 'category', 'created_at']
    search_fields = ['title', 'content']
    prepopulated_fields = {'slug': ('title',)}
    list_editable = ['status']
    date_hierarchy = 'created_at'


@admin.register(Comment)
class CommentAdmin(admin.ModelAdmin):
    list_display = ['id', 'post', 'author', 'is_approved', 'created_at']
    list_filter = ['is_approved', 'created_at']
