anet-common 0.1.7

Common utilities, settings, and contracts for Anet Microservices (Django/DRF)

Anet Common Library

Ushbu kutubxona Anet loyihasining mikroservislari uchun umumiy standartlar, sozlamalar va yordamchi vositalarni (utilities) o'z ichiga oladi.

O'rnatish

pip install anet-common

(Yoki private repodan o'rnatish)

Eslatma: drf-spectacular[sidecar] allaqachon dependency sifatida kiritilgan. Swagger UI va ReDoc statik fayllari CDN o'rniga lokal paketdan yuklanadi — tashqi internet mavjud bo'lmagan dev tarmoqlarda ham ishlaydi.

Foydalanish

Mikroservisning settings.py faylida ushbu kutubxonadan standart konfiguratsiyalarni import qiling va ularni kengaytiring (extend).

settings.py namunasi:

from anet_common.conf import (
    COMMON_LANGUAGES,
    COMMON_MODELTRANSLATION_LANGUAGES,
    COMMON_REST_FRAMEWORK,
    COMMON_SPECTACULAR_SETTINGS,
    COMMON_SPECTACULAR_APPS,
)

# INSTALLED APPS
INSTALLED_APPS = [
    "modeltranslation",
    # ...
    "rest_framework",
    # ...
] + COMMON_SPECTACULAR_APPS
# COMMON_SPECTACULAR_APPS = ["drf_spectacular", "drf_spectacular_sidecar"]

# 1. MIDDLEWARE
MIDDLEWARE = [
    "anet_common.middleware.RequestIdMiddleware",  # Eng yuqorida tursin
    "django.middleware.locale.LocaleMiddleware",
    # ... boshqa middlewarelar
]

# 2. TILLAR VA VAQT
TIME_ZONE = "Asia/Tashkent"
LANGUAGE_CODE = "uz"
LANGUAGES = COMMON_LANGUAGES
# Natija: (('uz', "O'zbek"), ('ru', "Русский"), ('en', "English"))

MODELTRANSLATION_LANGUAGES = COMMON_MODELTRANSLATION_LANGUAGES
MODELTRANSLATION_DEFAULT_LANGUAGE = "uz"

# 3. DRF SOZLAMALARI
REST_FRAMEWORK = COMMON_REST_FRAMEWORK.copy()
REST_FRAMEWORK.update({
    # Loyihaga xos qo'shimchalar
    "DEFAULT_PERMISSION_CLASSES": (
        "rest_framework.permissions.IsAuthenticated",
    ),
})

# 4. SPECTACULAR (SWAGGER) SOZLAMALARI
# SWAGGER_UI_DIST va REDOC_DIST = "SIDECAR" allaqachon o'rnatilgan:
# statik fayllar CDN o'rniga drf_spectacular_sidecar paketidan yuklanadi.
SPECTACULAR_SETTINGS = COMMON_SPECTACULAR_SETTINGS.copy()
SPECTACULAR_SETTINGS.update({
    "TITLE": "Mening Mikroservis API",
    "DESCRIPTION": "Bu servis faqat ... uchun javob beradi",
    "VERSION": "1.0.0",
})

# 5. SERVIS MA'LUMOTLARI (Meta uchun)
SERVICE_NAME = "my-service"
SERVICE_VERSION = "v1"

urls.py namunasi:

from django.urls import path, include
from anet_common.spectacular.urls import urlpatterns as spectacular_urls

urlpatterns = [
    # Spectacular (Swagger UI + ReDoc) — lokal sidecar statikasidan
    path("api/", include(spectacular_urls)),
    # Natija:
    #   GET /api/schema/            — OpenAPI JSON/YAML schema
    #   GET /api/schema/swagger-ui/ — Swagger UI
    #   GET /api/schema/redoc/      — ReDoc

    # ... boshqa url'lar
]

Swagger UI va ReDoc uchun URL prefix ("api/") loyihaga qarab o'zgartirish mumkin.

Statik fayllarni yig'ish

drf_spectacular_sidecar statik fayllarni paket ichida saqlaydi. Deployment oldidan odatdagi collectstatic buyrug'i yetarli:

python manage.py collectstatic --noinput

views.py da pagination namunasi:

class TestAPIView(generics.APIView):  # or GenericAPIView
    queryset = MyObject.objects.all()
    serializer_class = MyObjectSerializer

    def get(self, request):
        qs = self.get_queryset()

        # 1. Querysetni sahifalash
        page = self.paginate_queryset(qs)

        # 2. Agar sahifalash muvaffaqiyatli bo'lsa
        if page is not None:
            serializer = self.get_serializer(page, many=True)
            return self.get_paginated_response(serializer.data)

        serializer = self.get_serializer(qs, many=True)
        return Response(serializer.data)

Tarkibi va Konstantalar

1. COMMON_LANGUAGES

Loyiha qo'llab-quvvatlaydigan 3 ta asosiy til:

• uz: O'zbek
• ru: Rus
• en: Ingliz

Umumiy COMMON_ qiymatlarining tarkibi

from django.utils.translation import gettext_lazy as _

# 1. COMMON LANGUAGES
COMMON_LANGUAGES = (
    ("uz", "O'zbek"),
    ("ru", "Русский"),
    ("en", "English"),
)

COMMON_MODELTRANSLATION_LANGUAGES = ("uz", "ru", "en")
COMMON_MODELTRANSLATION_DEFAULT_LANGUAGE = "uz"

# 2. COMMON REST FRAMEWORK SETTINGS
COMMON_REST_FRAMEWORK = {
    "DEFAULT_RENDERER_CLASSES": (
        "anet_common.drf.renderers.AnetJSONRenderer",
    ),
    "DEFAULT_PARSER_CLASSES": (
        "djangorestframework_camel_case.parser.CamelCaseJSONParser",

}

# 3. COMMON SPECTACULAR SETTINGS

    "SERVE_INCLUDE_SCHEMA": False,
    "COMPONENT_SPLIT_REQUEST": True,
    "COMPONENT_NO_READ_ONLY_REQUIRED": True,
    "POSTPROCESSING_HOOKS": [
        "drf_spectacular.hooks.postprocess_schema_enums",

}

# 4. SPECTACULAR UCHUN ZARUR INSTALLED_APPS
COMMON_SPECTACULAR_APPS = [
    "drf_spectacular",
    "drf_spectacular_sidecar",
]

2. COMMON_REST_FRAMEWORK

Quyidagi standart sozlamalarni o'z ichiga oladi:

• Renderer: AnetJSONRenderer — javoblarni standart formatga o'tkazadi.
• Parser: CamelCaseJSONParser va standart parserlar.
• Exception Handler: custom_exception_handler — xatolarni katalogdan olib, yagona formatga o'tkazadi.
• Pagination: StandardPageNumberPagination (default page_size=20).

4. meta.timing — So'rov vaqti

Har bir javobda meta.timing maydoni avtomatik to'ldiriladi. Buning uchun RequestIdMiddleware MIDDLEWARE ro'yxatida eng yuqorida turishi shart.

Maydon	Ta'rif
total_ms	So'rov kelgandan JSON render tugagunga qadar to'liq vaqt
breakdown.app_ms	Middleware + view logikasi + ORM + serializer vaqti
breakdown.renderer_ms	Faqat JSON render qilish vaqti

Eslatma: timing maydoni faqat RequestIdMiddleware o'rnatilgan bo'lsa to'ldiriladi. Middleware mavjud bo'lmasa, timing meta ichida ko'rinmaydi.

Xatoliklar Katalogi

Xatoliklar markazlashgan JSON katalogi orqali boshqariladi. Yangi xatolik qo'shish uchun kutubxona yangilanishi kerak.
