FastAPI With Databases
Quiz on integrating FastAPI with SQLAlchemy and async database operations.
1. FastAPI natively supports which type of database operations for better performance with async endpoints?
Synchronous only
Asynchronous only
Both synchronous and asynchronous
Neither
2. Which dependency pattern is commonly used in FastAPI to manage database sessions and ensure they close after requests?
Depends(get_db)
SessionLocal()
engine.connect()
db_context()
3. What is the recommended way to define database models when using SQLAlchemy with FastAPI?
Using Pydantic models directly
Using SQLAlchemy declarative base classes
Using FastAPI's Model class
Using JSON schemas
4. Which Pydantic model type is used to validate incoming data (e.g., from POST requests) before saving to a database in FastAPI?
Response model
Input model (e.g., CreateModel)
Database model
Schema model
5. Which async database driver is commonly used with PostgreSQL and SQLAlchemy in FastAPI?
psycopg2
asyncpg
sqlite3
mysql-connector
6. Which of the following are benefits of using an ORM like SQLAlchemy with FastAPI?
Reduced boilerplate SQL code
Automatic database migrations
Type safety for database operations
Built-in authentication
Simplified CRUD operations
7. Which components are typically included in a database URL for connecting FastAPI to a database?
Database type (e.g., postgresql)
Username
Password
Server IP/hostname
FastAPI version
8. Which HTTP methods are used in FastAPI endpoints to perform CRUD operations on a database?
POST (Create)
GET (Read)
PUT/PATCH (Update)
DELETE (Delete)
COMPILE (Compile)
9. What are advantages of using async database operations in FastAPI?
Better scalability with many concurrent connections
Faster execution for CPU-bound tasks
Non-blocking I/O during database queries
Simpler code than synchronous operations
Native support for WebSockets
10. FastAPI can only interact with SQL databases and not NoSQL databases like MongoDB.
True
False
11. Pydantic models in FastAPI validate incoming data before it is converted to database model instances.
True
False
12. Developers must manually close database sessions in FastAPI after each request to prevent connection leaks.
True
False
13. What is the name of the tool commonly used with SQLAlchemy and FastAPI to manage database schema migrations?
14. What decorator is used in FastAPI to define an endpoint that creates a new record in a database (e.g., POST request)?
15. In the context of FastAPI and databases, what does the acronym 'CRUD' stand for?
