47-50: Support single-item retrieval viaidto align with LightAPI model routes.Since this class has

234-237: Parse ISO timestamps for robust date sorting.String sort works for ISO-8601, but parsing is safer and clearer.
- elif sort_by in ['created_at', 'updated_at']: - # Date sorting - return sorted(products, key=lambda x: x[sort_by], reverse=reverse) + elif sort_by in ['created_at', 'updated_at']: + # Date sorting + return sorted(products, key=lambda x: datetime.fromisoformat(x[sort_by]), reverse=reverse)
258-266: Addidhandling to SearchableArticle for consistency with model routes.Mirror the product endpoint: if

109-117: Mirror id validation in sync endpoint.Same non-numeric id issue as the async endpoint.
Apply this diff:
- item_id = request.path_params.get('id') - if item_id: - return { - "id": int(item_id), - "name": f"Fast Item {item_id}", - "value": float(item_id) * 5.0, + item_id = request.path_params.get('id') + if item_id: + try: + item_id_int = int(item_id) + except ValueError: + return {"error": "Invalid id"}, 400 + return { + "id": item_id_int, + "name": f"Fast Item {item_id_int}", + "value": float(item_id_int) * 5.0, "processing_time": 0.1, "message": "Retrieved with sync processing" }
104-108: Intentional blocking: confirm this is strictly for demonstration.Because LightAPI’s handler invokes sync endpoint methods directly,
time.sleep()will block the event loop and degrade concurrency across the app. If this is only to illustrate the difference, fine; otherwise, consider making this endpoint async or offloading to a thread pool.examples/yaml_advanced_permissions.py (6)
30-32: Enable SQLite FK enforcement during setup.Turn on foreign_keys so violations are caught during data load.
conn = sqlite3.connect(db_path) - cursor = conn.cursor() + conn.execute("PRAGMA foreign_keys=ON") + cursor = conn.cursor()
16-20: Import textwrap for dedenting the multi-line YAML.Prevents leading indentation from the function block affecting YAML.
import os import sqlite3 import tempfile +import textwrap from lightapi import LightApi
176-176: Dedent YAML content to avoid unintended leading indentation.Safer across YAML parsers.

96-148: Avoid blind exception handling; let LightApi surface 500s.Rely on the framework’s handler for unexpected errors and only handle expected ones. This also addresses Ruff BLE001/TRY300.

149-195: Same here: narrow or remove broad except in PUT; keep partial-update logic.This clears BLE001/TRY300 and relies on the framework’s exception handling.
- def put(self, request): - """Update user with validation""" - try: - user_id = request.path_params.get('id') - if not user_id: - return {"error": "User ID is required"}, 400 - - try: - user_id = int(user_id) - except ValueError: - return {"error": "Invalid user ID format"}, 400 - - data = request.data - - # Validate input data (PUT allows partial updates) - errors = self.validate_data(data, method='PUT') - if errors: - return { - "error": "Validation failed", - "details": errors, - "received_data": data - }, 400 - - # Simulate checking if user exists - if user_id == 999: - return {"error": "User not found"}, 404 - - # Simulate update - updated_user = { - "id": user_id, - "username": data.get('username', f'user_{user_id}'), - "email": data.get('email', f'user_{user_id}@example.com'), - "age": int(data.get('age', 25)), - "salary": float(data.get('salary', 0)) if data.get('salary') is not None else None, - "is_active": data.get('is_active', True), - "updated_at": datetime.utcnow().isoformat(), - "message": "User updated successfully" - } - - return updated_user, 200 - - except Exception as e: - return { - "error": "Internal server error", - "message": str(e) - }, 500 + def put(self, request): + """Update user with validation""" + user_id = request.path_params.get('id') + if not user_id: + return {"error": "User ID is required"}, 400 + + try: + user_id = int(user_id) + except ValueError: + return {"error": "Invalid user ID format"}, 400 + + data = request.data + + # Validate input data (PUT allows partial updates) + errors = self.validate_data(data, method='PUT') + if errors: + return { + "error": "Validation failed", + "details": errors, + "received_data": data + }, 400 + + # Simulate checking if user exists + if user_id == 999: + return {"error": "User not found"}, 404 + + # Simulate update + updated_user = { + "id": user_id, + "username": data.get('username', f'user_{user_id}'), + "email": data.get('email', f'user_{user_id}@example.com'), + "age": int(data.get('age', 25)), + "salary": float(data.get('salary', 0)) if data.get('salary') is not None else None, + "is_active": data.get('is_active', True), + "updated_at": datetime.utcnow().isoformat(), + "message": "User updated successfully" + } + + return updated_user, 200
163-165: PUT is used as partial update; consider PATCH or clarify semantics.Comment says “PUT allows partial updates”. Standard practice is PATCH for partial updates; either rename to patch() or document this deviation.
181-184: Avoid defaulting unspecified fields on partial updates.For PUT-as-partial, setting is_active to True when absent can inadvertently flip state. Prefer leaving it unchanged or omitting it in the response if not provided.
- "is_active": data.get('is_active', True), + "is_active": data['is_active'] if 'is_active' in data else None # leave unchanged in real impl
236-243: DRY the category list and normalize once.Define a VALID_CATEGORIES constant and reuse; also normalize category to lower once.
- category = data.get('category', '').strip() - valid_categories = ['electronics', 'clothing', 'books', 'home', 'sports', 'toys'] + category = data.get('category', '').strip().lower() if method == 'POST' and not category: errors.append("Category is required") - elif category and category.lower() not in valid_categories: - errors.append(f"Category must be one of: {', '.join(valid_categories)}") + elif category and category not in VALID_CATEGORIES: + errors.append(f"Category must be one of: {', '.join(VALID_CATEGORIES)}")- "valid_categories": ['electronics', 'clothing', 'books', 'home', 'sports', 'toys'] + "valid_categories": VALID_CATEGORIESAdd this constant near the imports:
VALID_CATEGORIES = ['electronics', 'clothing', 'books', 'home', 'sports', 'toys']Also applies to: 262-263
251-283: Remove blind except in product POST as well.Mirror the earlier change; let unexpected errors bubble to the framework handler.
- def post(self, request): - """Create product with validation""" - try: - data = request.data - - # Validate input data - errors = self.validate_product_data(data, method='POST') - if errors: - return { - "error": "Product validation failed", - "details": errors, - "valid_categories": ['electronics', 'clothing', 'books', 'home', 'sports', 'toys'] - }, 400 - - # Create product (simulated) - new_product = { - "id": 456, # Simulated auto-generated ID - "name": data['name'].strip(), - "price": float(data['price']), - "category": data['category'].lower(), - "description": data.get('description', '').strip() or None, - "in_stock": data.get('in_stock', True), - "created_at": datetime.utcnow().isoformat(), - "message": "Product created successfully" - } - - return new_product, 201 - - except Exception as e: - return { - "error": "Internal server error", - "message": str(e) - }, 500 + def post(self, request): + """Create product with validation""" + data = request.data + + # Validate input data + errors = self.validate_product_data(data, method='POST') + if errors: + return { + "error": "Product validation failed", + "details": errors, + "valid_categories": VALID_CATEGORIES + }, 400 + + # Create product (simulated) + new_product = { + "id": 456, # Simulated auto-generated ID + "name": data['name'].strip(), + "price": float(data['price']), + "category": data['category'].lower(), + "description": data.get('description', '').strip() or None, + "in_stock": data.get('in_stock', True), + "created_at": datetime.utcnow().isoformat(), + "message": "Product created successfully" + } + + return new_product, 201
32-33: Money fields: prefer Decimal/Numeric over Float (demo comment).For real apps, Float can introduce rounding issues. Consider SQLAlchemy Numeric(precision, scale) with Decimal.
Example:
from decimal import Decimal from sqlalchemy import Numeric salary = Column(Numeric(12, 2), nullable=True) price = Column(Numeric(12, 2), nullable=False) # When building responses: "salary": Decimal(str(data.get("salary"))) if data.get("salary") is not None else None "price": Decimal(str(data["price"]))Also applies to: 203-204
309-337: Consider adding a PUT example to exercise update validation.A quick PUT curl helps users try partial updates.
print("✅ Valid user creation:") print('curl -X POST http://localhost:8000/validated_users \\') print(' -H "Content-Type: application/json" \\') print(' -d \'{"username": "john_doe", "email": "[email protected]", "age": 30, "salary": 50000}\'') + print() + print("✅ Valid user update (partial):") + print('curl -X PUT http://localhost:8000/validated_users/123 \\') + print(' -H "Content-Type: application/json" \\') + print(' -d \'{"email": "[email protected]"}\'')examples/config_basic.yaml (1)

In docs/deployment/production.md around lines 769–779, the middleware is only
setting 'content-encoding: gzip' without compressing the response body, which
breaks clients; replace this header-only approach with a real compression
solution: either use the framework's built-in GZip/GZipMiddleware or perform
actual gzip compression of the response body before setting the header (and
update Content-Length/streaming handling accordingly), and alternatively
document terminating compression at the reverse proxy (Nginx) as an option;
ensure the header is only set when the body has been compressed.

claim enforced role-scoped behavior (e.g., “customers see own, managers see
all”) which is misleading; update the comment text to clarify that these are
intended behaviors or suggestions and are not enforced by the configuration
itself, and add a short TODO line explaining that backend authorization or
row-level filters must be implemented to enforce them (or link to the relevant
auth/ACL example); keep the CRUD list as-is but change phrasing to something

Docs mismatch: RedisCache constructor and app.add_cache usage are incorrect
- Docs show
RedisCache(url=..., default_ttl=..., key_prefix=...)andapp.add_cache(...). Implementation definesRedisCache(host: str='localhost', port: int=6379, db: int=0)andset(..., timeout=300)(nodefault_ttl/key_prefix) — see lightapi/cache.py. - There is no
LightApi.add_cachemethod; cache wiring usesconfig.caching_class()(lightapi/rest.py:212) or by assigningendpoint.cachein examples — see lightapi/lightapi.py and examples/. - Action: update docs/examples/readonly-apis.md to use the actual constructor and show correct wiring (via config or endpoint.cache), or change the implementation to accept
url/default_ttl/key_prefixand provideadd_cache.

In docs/examples/readonly-apis.md around lines 492 to 505, the example uses a
RedisCache constructor and app.add_cache API that don't exist; update the
snippet to use the actual RedisCache(host: str='localhost', port: int=6379, db:
int=0) signature, remove default_ttl and key_prefix parameters, and remove
app.add_cache usage; instead show how to wire caching correctly by either (A)
setting the caching_class in the analytics_api.yaml config to instantiate
RedisCache, or (B) assigning endpoint.cache = RedisCache(host="localhost",
port=6379, db=0) and demonstrate using cache.set(key, value, timeout=300) for
TTL behavior.

Docker entrypoint likely incorrect for aiohttp-based app.run() apps.
If LightAPI isn’t ASGI/Starlette, uvicorn main:app won’t work. Use your bootstrap script instead.
-CMD ["python", "-m", "uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
+CMD ["python", "main.py"]If Starlette/ASGI mode is supported, document both options and when to use each.

In README.md around lines 1182 to 1196, the Dockerfile example uses "uvicorn
main:app" which is incorrect for aiohttp-based apps that use app.run() (LightAPI
non-ASGI); replace the CMD to invoke the project's bootstrap/entrypoint script
(the same script used to start the service locally) so the container runs the
aiohttp server, and update the README to document both options: (1) run the
bootstrap/entrypoint for aiohttp/app.run() and (2) use "uvicorn main:app" only
if the project exposes a Starlette/ASGI-compatible app — include a short note
explaining when to use each.

Invalid example: using await inside a sync def method.
Switch to an async handler to make this code valid.

In README.md around lines 1302 to 1316, the example uses await inside a
synchronous def handler; change the handler to an async function (e.g., async
def post(self, request: Request)) so awaits are valid, and update the example
text to reflect an async handler for Starlette file uploads; ensure any
surrounding narrative or decorators still match async usage.

Correct unsupported environment-variable expansion in YAML example
from_config only resolves ${...} for database_url. The example suggests env expansion for other fields, which is misleading.

In YAML_CONFIGURATION_GUIDE.md around lines 213–218, the example wrongly shows
${...} expansion for swagger_title, swagger_version, and swagger_description
though from_config only resolves ${...} for database_url; update the example so
only database_url uses "${DATABASE_URL}" and change the swagger fields to
literal/static placeholders (e.g., plain text or empty values) to avoid implying
unsupported environment-variable expansion.

Align environment variable exports with actual support
Since only database_url is resolved in YAML, exporting API_TITLE, etc. has no effect.

In YAML_CONFIGURATION_GUIDE.md around lines 305 to 310, the docs incorrectly
show uvicorn and the UvicornWorker for a LightAPI app (which uses aiohttp);
update the commands to use the aiohttp Gunicorn worker instead: replace the
uvicorn run line with a development command appropriate for aiohttp (or note
using aiohttp's built-in runner) and change the gunicorn production example to
use the aiohttp Gunicorn worker (aiohttp.GunicornWebWorker) so the server is
started with the correct worker class.
