The Rust `QueryNode` builder methods use `#[must_use]` and `self` (not `&mut self`) for the same immutability guarantee. + +2. **AnyPool over typed pools** — Uses `sqlx::any::AnyPool` for a single code path across Postgres/MySQL/SQLite. Loses compile-time query checking but gains runtime flexibility. + +3. **GIL minimization** — Rust executor decodes rows to `HashMap` first, then converts to `PyDict` only at the PyO3 boundary. This avoids holding the GIL during SQL execution. + +4. **ContextVar transaction propagation** — Active transactions are stored in `contextvars.ContextVar` so they propagate through async call stacks without explicit passing. + +5. **Two-tier lookup registry** — Built-in lookups are static `fn` pointers (fast, thread-safe). Custom lookups store pre-rendered SQL templates with `{col}` placeholders. Custom lookups can override built-ins (checked first). + +6. **Deferred reverse FK resolution** — ForeignKey fields with string forward references accumulate in `_pending_reverse_fk` and are resolved after each model class is defined by the metaclass. + +### Dependency Versions + +| Crate | Version | Role | +|---|---|---| +| `pyo3` | `>=0.28.3` | Python ↔ Rust bindings | +| `pyo3-async-runtimes` |

Explicit Routing + +You can force a query to run on a specific database using the `.using()` method. This is useful for one-off queries or manual routing. + +```python +# Read from the 'users' database +users = await User.objects.using("users").all() + +# Write to the 'logs' database +await Log.objects.using("logs").create(message="System boot") +``` + +### 2.

Dynamic Routing (The Router) + +For more complex logic (e.g., routing based on the environment, user, or model type), you can implement a custom router by inheriting from `BaseRouter`. + +```python +from ryx.router import BaseRouter, set_router + +class MyProjectRouter(BaseRouter): + def db_for_read(self, model, **hints): + if model.__name__ == "User": + return "users" + return None # Fallback to default + + def db_for_write(self, model, **hints): + if model.__name__ == "User": + return "users" + return None + +# Activate the router globally +set_router(MyProjectRouter()) +``` + +## Multi-Database Transactions + +Transactions in Ryx are tied to a specific database connection.

Remove Python-side SQL generation and execution for updates, simplify value collection and PK assignment logic (handle DB-specific return formats). Also tidy imports and avoid name shadowing in Manager.bulk_update by aliasing the imported function, and tighten QuerySet.__init__ model typing to Model. These changes move heavy lifting to native code for performance and lower FFI overhead. --- ryx/bulk.py | 82 +++++++++++++++++-------------------------------- ryx/models.py | 4 +-- ryx/queryset.py | 2 +- 3 files changed, 32 insertions(+), 56 deletions(-) diff --git a/ryx/bulk.py b/ryx/bulk.py index a46f0b1..b5a5119 100644 --- a/ryx/bulk.py +++ b/ryx/bulk.py @@ -25,13 +25,13 @@ from __future__ import annotations -# import asyncio -# import itertools from typing import List, Sequence, Type, TYPE_CHECKING if TYPE_CHECKING: from ryx.models import Model +from ryx import ryx_core as _core + def _detect_backend() -> str: """Detect the database backend from the RYX_DATABASE_URL env var. @@ -113,12 +113,20 @@ async def bulk_create( pk_field = model._meta.pk_field - # Process in batches + # Process in batches — all SQL and execution handled in Rust for batch in _chunked(instances, batch_size): - pks = await _insert_batch(model, batch, fields, col_names, ignore_conflicts) - # Assign returned PKs to instances - for inst, pk in zip(batch, pks): - object.__setattr__(inst, pk_field.attname, pk) + rows = [[f.to_db(getattr(inst, f.attname)) for f in fields] for inst in batch] + res = await _core.bulk_insert( + model._meta.table_name, + col_names, + rows, + True, # returning_id + ignore_conflicts, + ) + # On PostgreSQL/SQLite res is list of ids; on MySQL res is rows_affected + if pk_field and isinstance(res, list): + for inst, pk in zip(batch, res): + object.__setattr__(inst, pk_field.attname, pk) return list(instances) @@ -255,11 +263,7 @@ async def bulk_update( } total = 0 - from ryx import ryx_core as _core - from ryx.pool_ext import execute_with_params - for batch in _chunked(instances, batch_size): - # Collect valid instances (with pk set) valid = [inst for inst in batch if inst.pk is not None] if not valid: continue @@ -268,55 +272,27 @@ async def bulk_update( pk_col = pk_field.column table = model._meta.table_name - # Build CASE WHEN clauses. - # Strategy: inline integers directly in SQL (zero FFI cost), - # use ? placeholders only for non-integer values. - case_clauses = [] - all_values = [] - + # Collect values per column in the order of pks + col_names: List[str] = [] + field_values: List[List[object]] = [] for fname in update_fields: if fname not in field_objs: continue fobj = field_objs[fname] - col = fobj.column - case_parts = [f'"{col}" = CASE "{pk_col}"'] - for inst in valid: - val = fobj.to_db(getattr(inst, fname)) - if isinstance(val, int) and not isinstance(val, bool): - # Inline integers — zero FFI overhead - case_parts.append(f"WHEN {inst.pk} THEN {val}") - else: - case_parts.append("WHEN ?

QuerySet was refactored to record high-level ops (filters, joins, annotations, group_by, order_by, limit/offset, distinct, using) and to materialize a QueryBuilder in one FFI call via ryx_core.build_plan. Compiler/CompiledQuery now carries base_table to help row decoding; executor uses the registry to decode columns with field specs (fallback heuristic kept). Also: make PyQueryBuilder internals and conversion helpers accessible to the crate, wire up model registration from ModelMetaclass, improve bulk_create return-id handling (Postgres vs SQLite), and various small API/formatting cleanups and pyi/type additions. --- ryx-query/src/compiler/compiler.rs | 2 + ryx/bulk.py | 23 ++- ryx/cache.py | 4 +- ryx/models.py | 28 ++++ ryx/queryset.py | 155 ++++++++++--------- ryx/relations.py | 13 +- ryx/ryx_core.pyi | 4 + src/executor.rs | 239 ++++++++++++++++++++--------- src/lib.rs | 110 ++++++++----- src/model_registry.rs | 147 ++++++++++++++++++ src/plan.rs | 181 ++++++++++++++++++++++ src/pool.rs | 67 ++++---- src/transaction.rs | 23 ++- 13 files changed, 760 insertions(+), 236 deletions(-) create mode 100644 src/model_registry.rs create mode 100644 src/plan.rs diff --git a/ryx-query/src/compiler/compiler.rs b/ryx-query/src/compiler/compiler.rs index 6987319..b403d7f 100644 --- a/ryx-query/src/compiler/compiler.rs +++ b/ryx-query/src/compiler/compiler.rs @@ -27,6 +27,7 @@ pub struct CompiledQuery { pub sql: String, pub values: SmallVec<[SqlValue; 8]>, pub db_alias: Option, + pub base_table: Option, } pub fn compile(node: &QueryNode) -> QueryResult { @@ -48,6 +49,7 @@ pub fn compile(node: &QueryNode) -> QueryResult { sql, values, db_alias: node.db_alias.clone(), + base_table: Some(node.table.clone()), }) } diff --git a/ryx/bulk.py b/ryx/bulk.py index b5a5119..c6c8204 100644 --- a/ryx/bulk.py +++ b/ryx/bulk.py @@ -114,19 +114,32 @@ async def bulk_create( pk_field = model._meta.pk_field # Process in batches — all SQL and execution handled in Rust + backend = _detect_backend() for batch in _chunked(instances, batch_size): rows = [[f.to_db(getattr(inst, f.attname)) for f in fields] for inst in batch] + # Returning IDs is expensive on SQLite/MySQL; we only request it on Postgres. + returning_ids = backend == "postgres" res = await _core.bulk_insert( model._meta.table_name, col_names, rows, -

-## Test Configuration - -- **Database**: Tests use SQLite in-memory database (`sqlite://:memory:`) -- **Isolation**: Each test function gets a clean database state -- **Async**: All tests are async and use `pytest-asyncio` -- **Fixtures**: Shared test data via `conftest.py` - -## Test Models - -The test suite uses these models defined in `conftest.py`: - -- **Author**: Basic model with CharField, EmailField, BooleanField, TextField -- **Post**: Complex model with ForeignKey, unique constraints, indexes, custom validation -- **Tag**: Simple model with unique CharField - -## Key Test Areas - -### Unit Tests -- Model metaclass and field contribution -- Field validation and type conversion -- Validator logic -- QuerySet building and Q object operations -- Exception hierarchy -

-### Integration Tests -Use fixtures from `conftest.py` for database setup and sample data: - -```python -@pytest.mark.asyncio -async def test_something(clean_tables, sample_author): - # Test logic here -

-### Database Errors -Tests expect SQLite. Check that the database URL in `conftest.py` is correct. - -### Test Failures -- Check test isolation (each test should clean up after itself) -- Verify fixture dependencies -- Check async/await usage -
