These policies will be automatically detected and included in database migrations. + +#### RLS Policy Structure +The `__rls_policies__` attribute is a dictionary where keys are policy names and values are policy configurations: + +```python +__rls_policies__ = { + "policy_name": { + "command": "SELECT", # Required: SQL command (SELECT, INSERT, UPDATE, DELETE, or ALL) + "using": "user_id = auth.uid()", # Required: USING clause for the policy + "check": "user_id = auth.uid()", # Optional: CHECK clause (for INSERT/UPDATE policies) + "permissive": True, # Optional: True for PERMISSIVE (default), False for RESTRICTIVE + } +} +``` + +#### Common RLS Patterns + +**User-owned rows pattern:** +```python +__rls_policies__ = { + "user_owns_row": { + "command": "SELECT", + "using": "user_id = auth.uid()", + } +} +``` + +**Full user control (CRUD operations):** +```python +__rls_policies__ = { + "user_owns_row": { + "command": "ALL", + "using": "user_id = auth.uid()", + "check": "user_id = auth.uid()", + } +} +``` + +**Organization-based access:** +```python +__rls_policies__ = { + "organization_access": { + "command": "SELECT", + "using": "organization_id = current_setting('app.current_organization')::uuid", + } +} +``` + +**Role-based access:** +```python +__rls_policies__ = { + "admin_full_access": { + "command": "ALL", + "using": "current_setting('app.user_role') = 'admin'", + }, + "user_read_only": { + "command": "SELECT", + "using": "current_setting('app.user_role') = 'user'", + } +} +``` + +**Multi-tenant pattern:** +```python +__rls_policies__ = { + "tenant_isolation": { + "command": "SELECT", + "using": "tenant_id = current_setting('app.current_tenant')::uuid", + } +} +``` + +**Global read with owner write pattern:** +```python +__rls_policies__ = { + "global_read_access": { + "command": "SELECT", + "using": "true", + }, + "owner_full_access": { + "command": "ALL", + "using": "organization_id IN (SELECT id FROM public.organizations WHERE owner_user_id = auth.uid())", + "check": "organization_id IN (SELECT id FROM public.organizations WHERE owner_user_id = auth.uid())", + }, +} +``` + +**Multi-owner pattern (profile or organization):** +```python +__rls_policies__ = { + "global_read_access": { + "command": "SELECT", + "using": "true", + }, + "owner_full_access": { + "command": "ALL", + "using": "(owner_profile_id = auth.uid() OR owner_organization_id IN (SELECT id FROM public.organizations WHERE owner_user_id = auth.uid()))", + "check": "(owner_profile_id = auth.uid() OR owner_organization_id IN (SELECT id FROM public.organizations WHERE owner_user_id = auth.uid()))", + }, +} +``` + +#### RLS Policy Migration + +When you run `make db_migration msg="Add RLS policies"`, Alembic will: + +1. **Enable RLS** on the table if not already enabled +2. **Create new policies** that don't exist in the database +3. **Generate SQL** like: + +```sql +ALTER TABLE public.your_table_name ENABLE ROW LEVEL SECURITY; +CREATE POLICY user_owns_row ON public.your_table_name + AS PERMISSIVE + FOR SELECT + USING (user_id = auth.uid()); +``` + +#### Policy Clauses + +- **USING clause**: Controls which existing rows are visible for SELECT operations and which rows can be affected by UPDATE/DELETE operations +- **CHECK clause**: Controls which new rows can be inserted or which values can be set during UPDATE operations +- **FOR SELECT**: Only uses the USING clause (CHECK clause is ignored) +- **FOR INSERT**: Only uses the CHECK clause (USING clause is ignored) +- **FOR UPDATE**: Uses both USING (to identify updatable rows) and CHECK (to validate new values) +- **FOR DELETE**: Only uses the USING clause (CHECK clause is ignored) +- **FOR ALL**: Uses both clauses as appropriate for each operation + +#### Important Notes + +- **User identification**: Use `auth.uid()` to get the current authenticated user's ID in RLS policies +- **Current settings**: Use PostgreSQL's `current_setting()` function for application-level variables like roles, organizations, etc. +- **Security context**: Your application must set context variables using `SET LOCAL` in each transaction +- **Policy testing**: Always test RLS policies in a development environment first +- **Performance**: RLS policies are evaluated on every query, so keep expressions efficient +- **Clean migrations**: Only RLS policy changes will be included in migrations; schema drift operations are automatically filtered out + + + +## Foreign Key Best Practices + +### 1. Use Schema Prefixes +Always use explicit schema prefixes in foreign key references to avoid resolution issues: + +```python +ForeignKeyConstraint( + ["user_id"], + ["public.profiles.user_id"], # ✅ CORRECT: explicit schema prefix + name="your_table_user_id_fkey", + ondelete="CASCADE", +) +``` + +**❌ AVOID:** +```python +ForeignKeyConstraint( + ["user_id"], + ["profiles.user_id"], # ❌ WRONG: missing schema prefix + name="your_table_user_id_fkey", + ondelete="CASCADE", +) +``` + +### 2. Handle Circular Dependencies +For models with circular dependencies, use `use_alter=True` to defer foreign key creation: + +```python +ForeignKeyConstraint( + ["organization_id"], + ["public.organizations.id"], + name="your_table_organization_id_fkey", + ondelete="SET NULL", + use_alter=True, # ✅ CORRECT: defer FK creation for circular deps +) +``` + +### 3. Recommended Helper Function +Use the foreign key management utility for automatic `use_alter` detection: + +```python +from src.db.utils.foreign_key_manager import create_foreign_key_constraint + +# In your model's __table_args__: +create_foreign_key_constraint( + columns=["user_id"], + referred_columns=["user_id"], + referred_table="profiles", + schema="public", + referred_schema="public", + name="your_table_user_id_fkey", + ondelete="CASCADE" +) +``` + +### 4. Index Foreign Keys +Always create indexes for foreign key columns: + +```python +Index("idx_your_table_user_id", "user_id"), +``` + +## Migration Validation + +### Before Creating Migrations +**ALWAYS** run migration validation before creating new migrations: + +```bash +# Quick validation +make db_validate + +# Full validation with detailed report +uv run -m src.db.utils.migration_validator --verbose + +# Strict validation (treat warnings as errors) +uv run -m src.db.utils.migration_validator --strict +``` + +### Pre-flight Checks +Before running migrations in production, always run pre-flight checks: + +```bash +# Complete pre-flight check +uv run -m src.db.utils.migration_validator --preflight +``` + +### Common Migration Issues and Solutions + +#### 1. Missing Model Imports +**Problem**: `NoReferencedTableError` when creating migrations +**Solution**: Ensure all models are imported in schema `__init__.py` files + +#### 2. Circular Dependencies +**Problem**: Foreign key resolution fails due to circular references +**Solution**: Use `use_alter=True` on foreign key constraints in the dependency cycle + +#### 3. Missing Schema Prefixes +**Problem**: Table resolution issues in complex schemas +**Solution**: Always use explicit schema prefixes (`public.table_name.column_name`) + +#### 4. Transaction Abort Issues +**Problem**: `InFailedSqlTransaction` errors during migration +**Solution**: Never use `use_alter=True` in `create_table` statements - only in model definitions + +## Migration Testing + +### 1. Test Locally First +Always test migrations on a development database before production: + +```bash +# Test current migration +make db_migrate + +# Test rollback +make db_downgrade + +# Test forward again +make db_migrate +``` + +### 2. Validate Migration Success +After running migrations, verify they worked correctly: + +```bash +# Check migration status +make db_status + +# Validate database connection +make db_test +``` + +### 3. Monitor for Issues +Watch for these common post-migration issues: +- Foreign key constraint violations +- RLS policy conflicts +- Index performance problems +- Data type mismatches + +## Automatic Discovery + +Models are automatically discovered from schema packages using the new model discovery system. The system will: + +1. **Scan** all Python files in `src/db/models/` subdirectories +2. **Import** modules and extract SQLAlchemy models +3. **Validate** that all models have required attributes +4. **Report** any missing or problematic models + +Manual imports in `src/db/models/__init__.py` are still maintained for backward compatibility and explicit control. \ No newline at end of file diff --git a/src/db/collate_models.py b/src/db/collate_models.py new file mode 100644 index 0000000..5e5ce1b --- /dev/null +++ b/src/db/collate_models.py @@ -0,0 +1,39 @@ +import importlib +import inspect +from types import ModuleType + +from src.db.models import Base +from loguru import logger as log + +# Programmatically import all models from the public schema +# Subclasses of Base: +TableType = Base + + +def _discover_models() -> list[TableType]: + """Dynamically discover and import all SQLAlchemy models from the public schema.""" + models: list[TableType] = [] + + #
