- Create missing db/ directory with __init__.py, base.py, and models.py - Add all required database models: User, Workspace, Agent, Issue, etc. - Implement SQLAlchemy base configuration with init_db, get_session - Fix package imports with lazy loading in __init__.py - Resolves ModuleNotFoundError that prevented tests from running Tests now begin executing instead of failing at import.

get_session signature incompatible with deps.py
deps.py imports this function and uses it as factory = get_session(); async with factory() as session: — treating it as if it returns a callable session factory. But get_session here is an async generator that yields a session directly. Calling get_session() returns an async generator object, and then factory() raises TypeError: 'async_generator' object is not callable, breaking every API route that depends on get_db().

In `@src/praisonai-platform/praisonai_platform/db/base.py`:
- Line 6: The import of sqlalchemy.Engine is unused and should be removed;
locate the top-level import statement that brings in Engine (the line "from
sqlalchemy import Engine") and delete it so only the async SQLAlchemy types from
sqlalchemy.ext.asyncio are imported/used (ensure any references rely on
AsyncEngine/async variants like AsyncEngine if needed).
- Around line 43-47: The sync reset_engine() should be made async and must
dispose the underlying AsyncEngine to avoid leaking connections: change
reset_engine to async def reset_engine(), check if _engine is an instance of
AsyncEngine and await _engine.dispose() (or call its dispose coroutine) before
setting _engine and _session_factory to None, and ensure callers await
reset_engine(); also remove the unused Engine import. Use the function and
globals named reset_engine, _engine, _session_factory and reference
AsyncEngine.dispose when implementing the fix.
- Around line 26-40: get_engine currently takes no arguments but tests call
get_engine("..."); update get_engine to accept an optional database_url:
Optional[str] = None, use the provided database_url when present otherwise fall
back to the DATABASE_URL env or default in-memory sqlite, and build the
AsyncEngine the same way (including the sqlite-specific connect_args) before
caching it in the module-level _engine; do not change the existing cache
semantics—if _engine is already set, return it (so callers must call
reset_engine() first to swap engines) and ensure reset_engine() clears the
cached _engine so subsequent get_engine(database_url=...) will create a new
engine.
In `@src/praisonai-platform/praisonai_platform/db/models.py`:
- Around line 114-115: Add proper foreign key constraints to the
user-referencing columns so they point to users.id and enforce referential

and ActivityLog.actor_id to use mapped_column(String, ForeignKey("users.id"),
nullable=...) instead of plain String columns (preserve existing nullable
behavior), ensuring imports for ForeignKey are present if not already; this will
align them with other FK columns like workspace_id/project_id/issue_id/label_id
and enable DB-level cascades/constraints.
- Around line 27-29: The DateTime columns in the models are declared without
timezone=True while _utcnow() returns a tz-aware datetime; update every DateTime
column declaration in this file (e.g., in the User and Project models) to
include timezone=True so stored values remain timezone-aware and match
_utcnow(), ensuring you change each DateTime(...) usage to DateTime(...,
timezone=True) for all timestamp fields referenced in User and Project.

get_engine() is called with a URL in tests but the signature accepts no args.
tests/test_client_integration.py line 24 calls engine = get_engine("sqlite+aiosqlite://"), which raises TypeError: get_engine() takes 0 positional arguments but 1 was given with the current signature.
Add an optional database_url parameter so callers can specify a URL without environment variables. Once an engine is cached, a subsequent call with a different URL silently returns the first engine; pair this parameter with reset_engine() (call first to clear the cache) to explicitly swap engines.

Make reset_engine() async and dispose the engine to prevent connection leaks.
The function is awaited in all test fixtures (test_api_integration.py, test_client_integration.py, test_new_api_integration.py), but currently defined as sync. More critically, it only drops the reference to _engine without disposing the underlying AsyncEngine connection pool, leaking aiosqlite connections across tests.

There was a problem hiding this comment.
Add timezone=True to all DateTime column declarations to match the tz-aware _utcnow() function.
_utcnow() returns datetime.now(timezone.utc) (tz-aware), but all DateTime columns are declared without the timezone=True parameter. This creates a mismatch: on SQLite the timezone info is silently stripped; on PostgreSQL SQLAlchemy warns and stores the value as naive, causing UTC/local time skew when reading back. This applies to all timestamp columns in the models (User and Project).

Add ForeignKey("users.id") on actor/assignee/author columns.
Issue.assignee_id, Issue.created_by_id, Comment.author_id, and ActivityLog.actor_id are plain String columns — no FK to users.id. That allows dangling IDs referencing deleted/nonexistent users, and prevents DB-level referential integrity and cascades. Comparable columns in this file (workspace_id, project_id, issue_id, label_id) all declare ForeignKey(...), so this is likely an oversight.

- Fix User model field mismatch: change username/hashed_password to name/password_hash to match auth_service.py expectations - Fix get_session() signature incompatibility: update deps.py to properly use async generator pattern - Add missing foreign key constraints for user references (assignee_id, created_by_id, author_id, actor_id) - Fix timezone handling: add timezone=True to all DateTime columns to match _utcnow() - Make reset_engine async and properly dispose connections to prevent leaks - Add database_url parameter to get_engine for test flexibility - Remove unused imports (Engine, Boolean) - Fix wildcard import in db/__init__.py using explicit module import for side effects - Add __dir__ method to main __init__.py for better tab completion Fixes all P1 runtime issues identified by Greptile and CodeRabbit reviewers. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>

name constraint causes unhandled IntegrityError on registration
User.name is marked unique=True, but AuthService.register() derives the name from the email prefix when the caller doesn't supply one (name or email.split("@")[0]). Two users with alice@company1.com and alice@company2.com would both be assigned name="alice", triggering an IntegrityError that propagates as an unhandled 500 response — no user can complete registration in that collision scenario.
Either remove the unique constraint if name is meant to be a display name, or surface a proper 409 error by catching IntegrityError in AuthService.register().

Fixes #1542
Problem
praisonai-platform tests failed at import with ModuleNotFoundError: praisonai_platform.db before any test execution. The entire db/ directory was missing from the package structure, but the codebase had imports throughout services and tests.
Solution
Created the missing database module structure:
Testing
Tests can start: pytest src/praisonai-platform/tests -q now collects 81 tests instead of failing at import
Acceptance Criteria Met
