- `GET /api/v1/report/{report_id}/download`: Download a report in specified format
- `GET /api/v1/report/{report_id}/progress`: Get the progress of a report generation
## Database Models
### User Model ✅
```python
class User(Base):
__tablename__ = "users"
id = Column(String, primary_key=True, index=True)
email = Column(String, unique=True, index=True, nullable=False)
hashed_password = Column(String, nullable=False)
full_name = Column(String, nullable=True)
is_active = Column(Boolean, default=True)
is_superuser = Column(Boolean, default=False)
```
### Search Model ✅
```python
class Search(Base):
__tablename__ = "searches"
id = Column(String, primary_key=True, index=True)
user_id = Column(String, ForeignKey("users.id"))
query = Column(String, nullable=False)
enhanced_query = Column(String, nullable=True)
query_type = Column(String, nullable=True)
engines = Column(String, nullable=True) # Comma-separated list
results_count = Column(Integer, default=0)
results = Column(JSON, nullable=True)
created_at = Column(DateTime, default=datetime.datetime.utcnow)
```
### Report Model ✅
```python
class Report(Base):
__tablename__ = "reports"
id = Column(String, primary_key=True, index=True)
user_id = Column(String, ForeignKey("users.id"))
search_id = Column(String, ForeignKey("searches.id"), nullable=True)
title = Column(String, nullable=False)
content = Column(Text, nullable=False)
detail_level = Column(String, nullable=False, default="standard")
query_type = Column(String, nullable=True)
model_used = Column(String, nullable=True)
created_at = Column(DateTime, default=datetime.datetime.utcnow)
updated_at = Column(DateTime, default=datetime.datetime.utcnow, onupdate=datetime.datetime.utcnow)
```
## Service Layer Integration
### Integration Strategy ✅
The service layer acts as a bridge between the API endpoints and the existing sim-search functionality. Each service:
1. Imports the corresponding sim-search components
2. Adapts the API request to the format expected by sim-search
3. Calls the sim-search functionality
4. Transforms the result to the API response format
Example from the implemented QueryService:
```python
# Add sim-search to the python path
sim_search_path = Path(settings.SIM_SEARCH_PATH)
sys.path.append(str(sim_search_path))
# Import sim-search components
from query.query_processor import QueryProcessor
from query.llm_interface import LLMInterface
class QueryService:
def __init__(self):
self.query_processor = QueryProcessor()
self.llm_interface = LLMInterface()
async def process_query(self, query: str) -> Dict[str, Any]:
# Process the query using the sim-search query processor
structured_query = await self.query_processor.process_query(query)
# Format the response
return {
"original_query": query,
"structured_query": structured_query
}
```
## Authentication System
### JWT-Based Authentication ✅
The authentication system uses JSON Web Tokens (JWT) to manage user sessions:
1. User logs in with email and password
2. Server validates credentials and generates a JWT token
3. Token is included in subsequent requests in the Authorization header
4. Server validates the token for each protected endpoint
Implementation using FastAPI's dependencies:
```python
oauth2_scheme = OAuth2PasswordBearer(tokenUrl=f"{settings.API_V1_STR}/auth/token")
def get_current_user(
db: Session = Depends(get_db), token: str = Depends(oauth2_scheme)
) -> models.User:
try:
payload = jwt.decode(
token, settings.SECRET_KEY, algorithms=[settings.ALGORITHM]
)
token_data = TokenPayload(**payload)
except (JWTError, ValidationError):
raise HTTPException(
status_code=status.HTTP_403_FORBIDDEN,
detail="Could not validate credentials",
)
user = db.query(models.User).filter(models.User.id == token_data.sub).first()
if not user:
raise HTTPException(status_code=404, detail="User not found")
if not user.is_active:
raise HTTPException(status_code=400, detail="Inactive user")
return user
```
## Implementation Phases
