Database adapter interface for PraisonAI Agents.

db

Database adapter interface for PraisonAI Agents.

This module provides the protocol and types for database persistence. Implementations are provided by the wrapper layer (praisonai.db).

Usage (simplest – recommended): from praisonaiagents import Agent, db

agent = Agent( name=”Assistant”, memory=db(database_url=”postgresql://localhost/mydb”), # db(…) shortcut ) agent.chat(“Hello!”) # auto-persists messages, runs, traces, tool calls

With an explicit session_id (use MemoryConfig): from praisonaiagents import Agent, db, MemoryConfig

agent = Agent( name=”Assistant”, memory=MemoryConfig(db=db(database_url=”postgresql://localhost/mydb”), session_id=”my-session”), # optional: defaults to per-hour ID )

Alternative (explicit backend, passed via memory=): memory=db.DB(database_url=”…”) # Short name (recommended) memory=db.PraisonAIDB(database_url=”…”) # Auto-detect backend memory=db.PostgresDB(host=”localhost”) # PostgreSQL memory=db.SQLiteDB(path=”data.db”) # SQLite memory=db.RedisDB(host=”localhost”) # Redis (state only)
