sqlalchemy_to_json_schema/command/main.py (2)
7-7: Approved: Direct import ofDriverclass.The change to directly import the
Driverclass simplifies the code and aligns with the new implementation in themainfunction. However, note that this reduces the flexibility of loading different drivers at runtime. Ensure this change aligns with the project's requirements for extensibility.
Line range hint
1-52: Summary of changes and potential impactThe changes in this file align with the PR objectives of code simplification and optimization. Key improvements include:
- Enhanced type safety with the use of
Finalfor constants.- Simplified driver instantiation, removing dynamic loading.
- Streamlined
mainfunction signature.These changes generally improve code clarity and maintainability. However, they also reduce some flexibility (e.g., in driver loading) which may impact extensibility.
Points to consider:
- Verify that removing the ability to load different drivers aligns with project requirements.
- Ensure the removal of the
depthparameter doesn't break any existing functionality.- The adoption of using results instead of exceptions (mentioned in PR objectives) is not directly visible in this file. Ensure this change is implemented consistently across the codebase.
tests/test_it_reflection.py (1)
Line range hint
1-70: Overall impact: Improved result handling in tests.The changes in this file successfully implement the new result handling pattern using the
Oktype from theresultmodule. This approach enhances error handling and aligns the tests with the modifications in the main code. The core expectations about the schema structure remain intact, ensuring that existing functionality is still properly tested.To further improve the tests:
- Consider adding test cases that specifically check for error conditions, using the counterpart to
Ok(likely anErrtype) to ensure comprehensive coverage of the new result handling pattern.- Update the docstrings or comments in the test functions to reflect the new result-based assertions, which would help maintain clear documentation of the test strategy.
Would you like assistance in implementing these suggestions or creating additional test cases to cover error scenarios?
tests/test_it.py (2)
45-45: Approve change and suggest fixing typo in function nameThe addition of
.unwrap()is correct and aligns with the PR objectives of using results instead of exceptions. This change improves error handling and result management.Consider fixing the typo in the function name:
-def test_it_create_schema__and__valid_params__sucess() -> None: +def test_it_create_schema__and__valid_params__success() -> None:
Line range hint
45-70: Summary of changes and suggestions for improvementThe changes in this file consistently add
.unwrap()to all schema generation calls, which aligns with the PR objectives of improving error handling and result management. This systematic update enhances the codebase's consistency in handling results.Consider creating a separate issue to address the following pre-existing typos, as they may affect test reliability:
- Function name typo: "sucess" instead of "success" in
test_it_create_schema__and__valid_params__sucess.- Parameter typo: "uesrs.pk" instead of "users.pk" in the
excludeslist oftest_it_create_schema__and__invalid_params__failure.Fixing these typos will improve the overall quality and reliability of the test suite.
tests/regression/test_generate_schema_with_type_decorator.py (1)
68-70: LGTM: Test case updated to handle Result type, but consider consistency.The changes in the
test_it__impl_is_not_callablefunction correctly adapt the test case to the new result-based approach. The use ofis_okto check for a successful result before accessing its value is appropriate.However, note that this test uses
unwrap()to access the result value, while the previous test usedvalue. For consistency, consider using the same method in both tests, preferablyunwrap()as it's more explicit about error handling.tests/command/test_main.py (2)
24-24: LGTM: Function signature simplified correctlyThe removal of the
mock_load_module_or_symbolparameter from the function signature is consistent with the PR objectives and the removal of the corresponding fixture. This change simplifies the test function without affecting its functionality.Consider updating the function's docstring to reflect the removal of the
mock_load_module_or_symbolparameter, ensuring that the documentation remains in sync with the code changes.
Line range hint
1-93: Overall assessment: Changes improve test simplicity and maintainabilityThe modifications in this file successfully simplify the test code by removing the
mock_load_module_or_symbolfixture and updating the test function signatures accordingly. These changes align well with the PR objectives of code simplification and removal of the ability to load different drivers.The updates maintain the functionality of the tests while reducing complexity, which should improve maintainability. The changes are consistent throughout the file and don't introduce any apparent issues.
Consider reviewing other test files in the project to ensure consistent application of these simplifications, if applicable. This will help maintain a uniform testing approach across the codebase.
tests/test_walker.py (4)
52-54: LGTM: Improved result handling and order-independent assertionThe changes in this test function effectively implement the new result-handling pattern and introduce order-independent assertion for property keys. This aligns well with the PR objectives and improves the robustness of the test.
Consider using
setinstead oflistfor a more concise representation:assert set(result.unwrap()["properties"].keys()) == set(["color", "name", "pk"])This achieves the same order-independent comparison without the need for the
unorderedfunction.
79-80: LGTM: Consistent implementation of result handlingThe changes in this test function correctly implement the new result-handling pattern, maintaining consistency with other test functions.
Consider renaming the test function to something more descriptive and following Python naming conventions. For example:
def test_properties_contain_all_expected_fields():This name more clearly describes the purpose of the test and follows the snake_case convention for Python function names.
97-99: LGTM: Improved result handling and order-independent assertionsThe changes in these test functions effectively implement the new result-handling pattern and introduce order-independent assertions for property keys. This aligns well with the PR objectives and improves the robustness of the tests.
Consider using
setinstead oflistfor a more concise representation in both functions:assert set(result.unwrap()["properties"].keys()) == {"pk"}and
assert set(result.unwrap()["properties"].keys()) == {"color", "name"}This achieves the same order-independent comparison without the need for the
unorderedfunction and is more idiomatic Python.Also applies to: 105-107
142-145: LGTM: Improved error handling using Result patternThe changes in this test function effectively implement the new result-handling pattern for error cases. Instead of expecting an exception, the test now checks for an
Errresult, which aligns well with the PR objectives of using results instead of exceptions.Consider using a more specific error message assertion:
expected_error = f"invalid overrides: {set(overrides.keys())}" assert actual == Err(expected_error)This approach makes the expected error message more explicit and easier to update if needed.
tests/test_relation.py (2)
60-62: LGTM: Improved test robustness and flexibility.The changes enhance the test by:
- Using
is_okto ensure the result is successful before accessing its value.- Using
unorderedfor a more flexible comparison of property keys.These modifications improve the test's reliability and reduce its sensitivity to the order of properties.
Consider adding an assertion for the
requiredfield, similar to other tests in this file:assert "required" in result.value
Line range hint
1-237: Overall improvements in test suite robustness and flexibilityThe changes made to
tests/test_relation.pyconsistently enhance the test suite's reliability and maintainability:
- Introduction of
is_okchecks ensures proper error handling and result validation.- Use of
unorderedcomparisons allows for more flexible assertions, reducing test brittleness.- Updated assertions reflect changes in the schema generation logic, particularly in areas such as nested relationships and handling of potential infinite loops.
These modifications align well with the PR objectives of code simplification and optimization. They contribute to a more robust test suite that is less prone to false negatives due to ordering issues or minor schema changes.
Consider adding a helper function to encapsulate the common pattern of checking
is_ok(result)and accessingresult.value. This could further reduce code duplication and improve readability across the test suite.tests/command/test_transformer.py (1)
Line range hint
88-114: Consider updatingcollect_modelsfor consistency.While the changes to use the Result type are appropriately applied to the transformer tests, the
collect_modelsfunction and its tests remain unchanged. For consistency across the codebase, it might be worth considering whethercollect_modelsshould also return a Result type (e.g.,Ok(list_of_models)orErr(error_message)). This would align all parts of the code with the new error-handling approach.Would you like me to propose a specific implementation for updating
collect_modelsto use the Result type?tests/test_schema_factory.py (6)
130-140: LGTM: Assertion updated to useOkwrapper.The change to wrap the expected result in
Okis consistent with the new approach of using a Result type. This modification enhances the test by explicitly checking for a successful outcome.Consider extracting the expected result into a separate variable before the assertion. This can improve readability, especially for larger dictionaries:
expected_result = { "properties": { "pk": {"type": "integer"}, "concatenable": {"type": "array", "items": {"type": expected_type}}, }, "required": ["pk"], "title": "Model", "type": "object", } assert actual == Ok(expected_result)
153-160: LGTM: Assertion updated to useOkwrapper.The change to wrap the expected result in
Okis consistent with the new approach of using a Result type. This modification enhances the test by explicitly checking for a successful outcome.As suggested earlier, consider extracting the expected result into a separate variable before the assertion to improve readability:
expected_result = { "properties": {"id": {"type": "string", "format": "uuid"}}, "required": ["id"], "title": "Model", "type": "object", } assert actual == Ok(expected_result)
174-184: LGTM: Assertion updated to useOkwrapper.The change to wrap the expected result in
Okis consistent with the new approach of using a Result type. This modification enhances the test by explicitly checking for a successful outcome.As suggested earlier, consider extracting the expected result into a separate variable before the assertion to improve readability:
expected_result = { "properties": { "id": {"type": "integer"}, "data": {"type": "object"}, }, "required": ["id"], "title": "Model", "type": "object", } assert actual == Ok(expected_result)
205-212: LGTM: Assertions updated to useOkwrapper in multiple test methods.The changes to wrap the expected results in
Okin bothtest_hybrid_propertyandtest_hybrid_property_with_mixinmethods are consistent with the new approach of using a Result type. These modifications enhance the tests by explicitly checking for successful outcomes.As suggested earlier, consider extracting the expected results into separate variables before the assertions in both methods to improve readability:
# In test_hybrid_property expected_result = { "properties": {"id": {"type": "integer"}}, "required": ["id"], "title": "Model", "type": "object", } assert actual == Ok(expected_result) # In test_hybrid_property_with_mixin expected_result = { "properties": {"id": {"type": "integer"}}, "required": ["id"], "title": "Model", "type": "object", } assert actual == Ok(expected_result)Also applies to: 234-241
319-319: LGTM: Assertions updated to useOkwrapper in remaining test methods.The changes to wrap the expected results in
Okin bothtest_hybrid_property_with_relationshipandtest_column_custom_columnmethods are consistent with the new approach of using a Result type. These modifications enhance the tests by explicitly checking for successful outcomes.For the
test_column_custom_columnmethod, consider extracting the expected result into a separate variable before the assertion to improve readability:expected_result = { "properties": {"pk": {"type": expected_type}}, "required": ["pk"], "title": "Model", "type": "object", } assert actual == Ok(expected_result)Also applies to: 365-372
Line range hint
1-372: Overall LGTM: Consistent implementation of Result type in test assertions.The changes made to this test file demonstrate a systematic approach to incorporating the Result type (
Ok) in test assertions. This modification enhances the test suite by explicitly checking for successful outcomes and aligns with a larger refactoring effort to use the Result type throughout the codebase.Key points:
- The
Okimport has been added to support the new assertion style.- All test methods have been updated consistently to use the
Okwrapper in their assertions.- The actual content of the expected results remains unchanged, preserving the original test logic.
These changes improve error handling and make success/failure states more explicit in the tests. They also prepare the test suite for potential future enhancements, such as handling error cases with a corresponding
Errtype.Consider the following to further improve the test suite:
- Update the docstrings of the test methods to reflect the new assertion style.
- If not already done, ensure that the main codebase (outside of tests) is also using this Result type consistently.
- Consider adding test cases that check for error conditions, using a corresponding
Errtype if available.sqlalchemy_to_json_schema/schema_factory.py (2)
334-335: Clarify error message for unused overridesWhen there are unused keys in
overrides_manager.not_used_keys, consider enhancing the error message to provide more context. For example, specify which override keys are invalid or suggest valid keys. This will aid in debugging.
423-427: Improve error message for unsupported mapped propertiesIn
_build_properties, when an unsupported mapped property is encountered, the error message could include more details about the property causing the issue. Providing the property name or type can help in troubleshooting.sqlalchemy_to_json_schema/command/transformer.py (1)
85-86: Provide a more descriptive error messageThe error message
Err(f"Expected a class or module, got {target}")could include the type oftargetfor clearer debugging.Consider refining the error message:
- return Err(f"Expected a class or module, got {target}") + return Err(f"Expected a class or module, got {type(target).__name__}: {target}")

8-8: Good job importing the 'result' module for structured error handlingThe addition of
from result import Err, Ok, Resultenables the use of theResulttype for more robust error handling. This is a positive change that improves the code's reliability.
22-22: Update method signatures in subclasses to match the new return typeThe abstract method
transformnow returnsResult[Schema, str]. Ensure all subclasses correctly override this method with the updated return type to maintain consistency and adhere to the new error handling pattern.
28-28: Consistent use of 'Result' in 'JSONSchemaTransformer.transform'The
transformmethod inJSONSchemaTransformercorrectly returnsResult[Schema, str], aligning with the updated abstract method. This consistent use ofResultenhances error handling across the codebase.
37-37: Improved error handling by returning 'Err' instead of raising exceptionsReplacing the exception with
return Err(f"Expected a class or module, got {item}")provides a consistent error handling approach using theResulttype. This avoids interrupting the flow with exceptions and makes error management more predictable.
39-44: Correctly checking for errors and unwrapping resultsThe code properly checks
if partial_definitions.is_err()and returns the error if present. On success, it unpacks the result withpartial_definitions.unwrap(). This pattern ensures that errors are handled gracefully and that only valid data is processed.

💡 Codebase verification
Exception-based error handling still present.
The 'result' dependency has been integrated and used in several areas. However, multiple instances of exception-based error handling (raise, except, try:) remain in the codebase. Please ensure that all error handling aligns with the PR objective of using results instead of exceptions.
🔗 Analysis chain
LGTM! Verify integration of the new 'result' dependency.
The addition of the 'result' dependency (version ^0.17.0) aligns with the PR objective of using results instead of exceptions for error handling. This is a good practice for more structured error handling.
To ensure smooth integration, please run the following script to check for any potential conflicts or issues:
This script will help identify where and how the new 'result' dependency is being used, and if there are any remaining exception-based error handling that might need to be updated.

Approve change and suggest fixing typo in excludes parameter
The addition of .unwrap() is correct and consistent with the changes in other functions.
There's a typo in the excludes parameter that might affect the test's effectiveness:
- schema = target(Group, excludes=["pk", "uesrs.pk"]).unwrap()
+ schema = target(Group, excludes=["pk", "users.pk"]).unwrap()This typo is pre-existing but should be fixed to ensure the test is excluding the intended field.

Fix type inconsistency in yield statement for MANYTOMANY relationship
In the UseForeignKeyIfPossibleDecision.decision method, within the elif prop.direction == MANYTOMANY block, the yield statement returns a tuple where the first element is a dictionary ({"type": "array", "items": {"type": "string"}}). However, the DecisionResult expects the first element to be of type ColumnPropertyType. This inconsistency necessitates the # type: ignore[arg-type] comment.
Consider defining a new member in ColumnPropertyType to represent this case (e.g., ColumnPropertyType.ARRAY) and adjust the yield statement accordingly. This will ensure type consistency and eliminate the need for the type ignore comment.

Consider handling potential exceptions from the dump method
While the run method now handles errors from self.transformer, consider that self.dump might raise exceptions (e.g., file I/O errors). To maintain consistent error handling, you could modify dump to return a Result type or handle exceptions within run.
Proposed Change to dump:
Modify the dump method to return a Result[None, str]:
def dump(
self,
data: dict[str, Any],
/,
*,
filename: Optional[Path] = None,
format: Optional[Format] = None,
- ) -> None:
+ ) -> Result[None, str]:
try:
dump_function = yaml.dump if format == Format.YAML else json.dump
if filename is None:
output_stream = sys.stdout
else:
output_stream = filename.open("w")
dump_function(data, output_stream) # type: ignore[operator]
+ return Ok(None)
except Exception as e:
+ return Err(str(e))Update run to Handle the Result from dump:
schema = self.transformer(modules_and_models, depth)
if schema.is_err():
return Err(schema.unwrap_err())
- self.dump(schema.unwrap(), filename=filename, format=format)
+ dump_result = self.dump(schema.unwrap(), filename=filename, format=format)
+ if dump_result.is_err():
+ return Err(dump_result.unwrap_err())
return Ok(None)This ensures that any errors from dump are captured and propagated correctly.

Inconsistent type annotations in get_children function
The get_children function specifies params as Sequence[str] | None, but the code checks if isinstance(params, dict):, which is inconsistent with the annotated type. Please update the type annotation of params to include Mapping[str, Any] | None if dictionaries are expected, or adjust the conditional checks to align with the annotated types.

Inconsistent wrapping of 'definitions' in the return statement
In transform_by_module, you're returning Ok({"definitions": definitions}), which wraps the definitions inside another definitions key. However, in other transformers, you return Ok(definitions) directly. This inconsistency could lead to confusion or errors when the output is used elsewhere. Consider standardizing the return structure across all transformers.

15-15: Function signature updated correctly.The change to return
Result[Schema, str]aligns well with the new error handling approach. This clearly indicates that the function can return either aSchemaor an error message.Consider adding or updating the function's docstring to reflect this change in return type and behavior.
52-54: Test case updated correctly for new Result type.The changes appropriately adapt the test case to the new
Result-based approach:
- Checking for success using
is_ok(result)before accessing the value.- Accessing the schema properties via
result.value.These changes ensure that the test case correctly handles the new error handling mechanism.
Consider adding an additional test case to verify the behavior when an error occurs (i.e., when
is_ok(result)would returnFalse).sqlalchemy_to_json_schema/schema_factory.py (5)
Line range hint
124-137: Improved type safety and standard exception handlingThe changes to the
__getitem__method are beneficial:
- The return type is now more specific, enhancing type safety.
- Using
KeyErrorinstead of a custom exception aligns with Python's standard practices for dictionary-like objects.These improvements make the code more predictable and easier to use.
Consider adding a type annotation to the
mappedvariable for even better type clarity:mapped: TypeFormatFn | None = None
272-290: Robust error handling with Result typeThe changes to
child_schemamethod significantly improve error handling:
- The return type
Result[dict[str, Any], str]allows for explicit error cases.- The new error handling logic (lines 282-285) properly propagates errors from subschema creation.
- Successful results are now wrapped in
Ok(...), adhering to the Result pattern.These changes make the method more robust and easier to use safely.
Consider adding a comment explaining the meaning of the error string in the
Errcase:if subschema_result.is_err(): # Propagate the error message from subschema creation return subschema_result
Line range hint
322-345: Enhanced error handling and configuration validationThe updates to
SchemaFactory.__call__method bring several improvements:
- The return type
Result[Schema, str]allows for explicit error reporting.- New error handling for the properties creation process (lines 329-330) ensures that errors are properly propagated.
- The additional check for unused overrides (line 335) helps catch potential misconfigurations.
These changes make the method more robust and help prevent silent errors.
Consider adding more context to the error message for unused overrides:
if overrides_manager.not_used_keys: return Err(f"Invalid overrides: {overrides_manager.not_used_keys}. These keys were not used in schema generation.")

411-478: Comprehensive error handling in property buildingThe updates to
SchemaFactory._build_propertiesmethod significantly enhance error handling:
- The return type
Result[dict[str, Any], str]allows for explicit success and failure cases.- New error handling in the decision loop (lines 424-427) provides specific error messages for unsupported properties.
- Consistent use of
Ok(...)andErr(...)for return statements improves code clarity.These changes make the method more robust and easier to debug when issues arise.
Consider adding more context to the error message for unsupported column types:
return Err(f"Unsupported column type: {type(column.type)}. Please ensure all column types are supported.")

1-501: Overall improvements in error handling and type safetyThe changes made to this file represent a significant improvement in error handling and type safety:
- Consistent use of the
Resulttype for error handling throughout the file.- More precise type annotations, especially in function return types.
- Better alignment with Python standards (e.g., using
KeyErrorinstead of custom exceptions).These changes will make the code more robust, easier to debug, and less prone to runtime errors. The consistent error handling pattern will also make it easier for users of this library to handle potential issues.
Consider adding documentation or comments explaining the new error handling pattern, especially if this is a public-facing library. This will help users understand how to properly handle potential errors when using the schema factory.

Test case updated for new Result type, but with inconsistent value access.
The changes correctly adapt the test case to the new Result-based approach:
- Checking for success using
is_ok(result)before accessing the value. - Accessing the schema properties via
result.unwrap().
While these changes ensure that the test case handles the new error handling mechanism, there's an inconsistency in how the result value is accessed compared to the previous test case.
The result.unwrap() usage here is inconsistent with result.value used in the previous test case. For consistency, consider using result.value here as well:
- assert result.unwrap()["properties"]["color"] == {"type": "string", "maxLength": 1}
+ assert result.value["properties"]["color"] == {"type": "string", "maxLength": 1}Alternatively, if unwrap() is preferred, update the previous test case to use it as well for consistency across the file.

LGTM: Improved error handling in run method
The run method has been updated to return a Result[None, str] and now includes proper error handling for the self.transformer call. This is a significant improvement in error management.
However, there's still room for improvement in handling potential errors from self.dump:
Consider updating the dump method to return a Result type and handle its potential errors in the run method. This would provide consistent error handling throughout the class. Here's a suggested implementation:
def dump(self, ...) -> Result[None, str]:
try:
# Existing implementation
return Ok(None)
except Exception as e:
return Err(str(e))
def run(self, ...):
# Existing implementation
dump_result = self.dump(schema.unwrap(), filename=filename, format=format)
if dump_result.is_err():
return Err(dump_result.unwrap_err())
return Ok(None)This change would ensure that any errors occurring during the dump process are also captured and propagated correctly.

Simplify error propagation in transform method
In OpenAPI3Transformer.transform, you unwrap the error only to wrap it again:
if definitions_result.is_err():
return Err(definitions_result.unwrap_err())You can simplify this by returning the definitions_result directly when an error occurs:
if definitions_result.is_err():
return definitions_resultThis approach maintains consistency with other methods and reduces unnecessary code.
