• Change reference resolution to use reference path instead of class name (fixes #342) (#366)
• If a schema references exactly one other schema in allOf, oneOf, or anyOf that referenced generated model will be used directly instead of generating a copy with another name. (#361)
• Attributes shadowing any builtin except id and type will now be renamed in generated clients (#360, #378, #407). Thanks @dblanchette and @forest-benchling!

0.8.0 - 2021-02-19

Breaking Changes

• Generated clients will no longer pass through None to query parameters. Previously, any query params set to None would surface as empty strings (per the default behavior of httpx). This is contrary to the defaults indicated by the OpenAPI 3.0.3 spec. Ommitting these parameters makes us more compliant. If you require a style of null to be passed to your query parameters, please request support for the OpenAPI "style" attribute. Thank you to @forest-benchling and @bowenwr for a ton of input on this.

Additions

• New --meta command line option for specifying what type of metadata should be generated:

  • poetry is the default value, same behavior you're used to in previous versions
  • setup will generate a pyproject.toml with no Poetry information, and instead create a setup.py with the project info.
  • none will not create a project folder at all, only the inner package folder (which won't be inner anymore)

• Attempt to detect and alert users if they are using an unsupported version of OpenAPI (#281).

• The media type application/vnd.api+json will now be handled just like application/json (#307). Thanks @jrversteegh!

• Support passing models into query parameters (#316). Thanks @forest-benchling!

• Add support for cookie parameters (#326).

• New --file-encoding command line option (#330). Sets the encoding used when writing generated files (defaults to utf-8). Thanks @dongfangtianyu!

Changes

• Lowered the minimum version of python-dateutil to 2.8.0 for improved compatibility (#298 & #299). Thanks @bowenwr!
• The from_dict method on generated models is now a @classmethod instead of @staticmethod (#215 & #292). Thanks @forest-benchling!
• Renamed all templates to end in .jinja, and all python-templates to end in .py.jinja to fix confusion with the latest version of mypy. Note this will break existing custom templates until you update your template file names.

Fixes

• Endpoint tags are now sanitized during parsing to fix an issue where My Tag and MyTag are seen as two different tags but are then later unified, causing errors when creating directories. Thanks @p1-ra! (#328)
• Parser will softly ignore value error during schema responses' status code convertion from string to integer (not a number). Errors will be reported to the end user and parsing will continue to proceed (#327).
• The generated from_dict and to_dict methods of models will now properly handle nullable and not required properties that are themselves generated models (#315). Thanks @forest-benchling!
• Fixed a typo in the async example in generated README.md files (#337). Thanks @synchronizing!
• Fix deserialization of None and Unset properties for all types by unifying the checks (#334). Thanks @forest-benchling!
• If duplicate model names are detected during generation, you'll now get an error message instead of broken code (#336). Thanks @forest-benchling!
• Fixes Enum deserialization when the value is UNSET (#306). Thanks @bowenwr!

0.7.3 - 2020-12-21

Fixes

• Spacing and extra returns for Union types of additionalProperties (#266 & #268). Thanks @joshzana & @packyg!
• Title of inline schemas will no longer be missing characters (#271 & #274). Thanks @kalzoo!
• Handling of nulls (Nones) when parsing or constructing dates (#267). Thanks @fyhertz!

0.7.2 - 2020-12-08

Fixes

• A bug in handling optional properties that are themselves models (introduced in 0.7.1) (#262). Thanks @packyg!

0.7.1 - 2020-12-08

Additions

• Support for additionalProperties attribute in OpenAPI schemas and "free-form" objects by adding an additional_properties attribute to generated models. COMPATIBILITY NOTE: this will prevent any model property with a name that would be coerced to "additional_properties" in the generated client from generating properly (#218 & #252). Thanks @packyg!

Fixes

• Enums will once again work with query parameters (#259). Thanks @packyg!
• Generated Poetry metadata in pyproject.toml will properly indicate Python 3.6 compatibility (#258). Thanks @bowenwr!

0.7.0 - 2020-11-25

Breaking Changes

• Any request/response field that is not required and wasn't specified is now set to UNSET instead of None.

• Values that are UNSET will not be sent along in API calls

• Schemas defined with type=object will now be converted into classes, just like if they were created as ref components. The previous behavior was a combination of skipping and using generic Dicts for these schemas.

• Response schema handling was unified with input schema handling, meaning that responses will behave differently than before. Specifically, instead of the content-type deciding what the generated Python type is, the schema itself will.

  • As a result of this, endpoints that used to return bytes when content-type was application/octet-stream will now return a File object if the type of the data is "binary", just like if you were submitting that type instead of receiving it.

• Instead of skipping input properties with no type, enum, anyOf, or oneOf declared, the property will be declared as None.

• Class (models and Enums) names will now contain the name of their parent element (if any). For example, a property declared in an endpoint will be named like {endpointname}{previousclassname}. Classes will no longer be deduplicated by appending a number to the end of the generated name, so if two names conflict with this new naming scheme, there will be an error instead.

Additions

• Added a --custom-template-path option for providing custom jinja2 templates (#231 - Thanks @erichulburd!).
• Better compatibility for "required" (whether or not the field must be included) and "nullable" (whether or not the field can be null) (#205 & #208). Thanks @bowenwr & @emannguitar!
• Support for all the same schemas in responses as are supported in parameters.
• In template macros: added declare_type param to transform and initial_value param to construct to improve flexibility (#241 - Thanks @packyg!).

Fixes

• Fixed spacing and generation of properties of type Union in generated models (#241 - Thanks @packyg!).
• Fixed usage instructions in generated README.md (#247 - Thanks @theFong!).

0.6.2 - 2020-11-03

Fixes

• Prefix generated identifiers to allow leading digits in field names (#206 - @kalzoo).
• Prevent autoflake from removing __init__.py imports during generation. (#223 - Thanks @fyhertz!)
• Update minimum Pydantic version to support Python 3.9

Additions

• Allow specifying the generated client's version using package_version_override in a config file. (#225 - Thanks @fyhertz!)

0.6.1 - 2020-09-26

Changes

• Use httpx ^0.15.0 in generated clients

Fixes

• Properly remove spaces from generated Enum keys (#198). Thanks @bowenwr!

Additions

• Endpoints without operationIds will have a name generated from their method and path (#92). Thanks @Kerybas & @dtkav!
• autoflake will be run on generated clients to clean up unused imports / variables (#138). Thanks @pawamoy!
• Note to README about supported OpenAPI versions (#176). Thanks @filippog!

0.6.0 - 2020-09-21

Breaking Changes

• Reorganized api calls in generated clients. async_api will no longer be generated. Each path operation will now have it's own module under its tag. For example, if there was a generated function api.my_tag.my_function() it is replaced with api.my_tag.my_function.sync(). The async version can be called with asyncio() instead of sync(). (#167)
• Removed support for mutable default values (e.g. dicts, lists). They may be added back in a future version given enough demand, but the existing implementation was not up to this project's standards. (#170)
• Removed generated errors module (and the ApiResponseError therein). Instead of raising an exception on failure, the sync() and asyncio() functions for a path operation will return None. This means all return types are now Optional, so mypy will require you to handle potential errors (or explicitly ignore them).
• Moved models.types generated module up a level, so just types.
• All generated classes that were dataclass now use the attrs package instead

Additions

• Every generated API module will have a sync_detailed() and asyncio_detailed() function which work like their non-detailed counterparts, but return a types.Response[T] instead of an Optional[T] (where T is the parsed body type). types.Response contains status_code, content (bytes of returned content), headers, and parsed (the parsed return type you would get from the non-detailed function). (#115)
• It's now possible to include custom headers and cookies in requests, as well as set a custom timeout. This can be done either by directly setting those parameters on a Client (e.g. my_client.headers = {"Header": "Value"}) or using a fluid api (e.g. my_endpoint.sync(my_client.with_cookies({"MyCookie": "cookie"}).with_timeout(10.0))).
• Unsupported content types or no responses at all will no longer result in an endpoint being completely skipped. Instead, only the detailed versions of the endpoint will be generated, where the resulting Response.parsed is always None. (#141)
• Support for Python 3.6 (#137 & #154)
• Support for enums with integer values

Changes

• The format of any errors/warnings has been spaced out a bit.

0.5.5 - 2020-09-04

Fixes

• Improved trailing comma handling in endpoint generation (#178 & #179). Thanks @dtkav!
• Optional is now properly imported for nullable fields (#177 & #180). Thanks @dtkav!

0.5.4 - 2020-08-29

Additions

• Support for octet-stream content type (#116)
• Support for nullable (#99)
• Union properties can be defined using oneOf (#98)
• Support for lists of strings, integers, floats and booleans as responses (#165). Thanks @Maistho!

0.5.3 - 2020-08-13

Security

• All values that become file/directory names are sanitized to address path traversal vulnerabilities (CVE-2020-15141)
• All values that get placed into python files (everything from enum names, to endpoint descriptions, to default values) are validated and/or saniziatied to address arbitrary code execution vulnerabilities (CVE-2020-15142)

Changes

• Due to security concerns/implementation complexities, default values are temporarily unsupported for any RefProperty that doesn't refer to an enum.
• Defaults for properties must now be valid values for their respective type (e.g. "example string" is an invalid default for an integer type property, and the function for an endpoint using it would fail to generate and be skipped).

Additions

• Added support for header parameters (#117)

Fixes

• JSON bodies will now be assigned correctly in generated clients(#139 & #147). Thanks @pawamoy!

0.5.2 - 2020-08-06

Additions

• Added project_name_override and package_name_override config options to override the name of the generated project/package (#123)
• The generated library's version is now the same as the OpenAPI doc's version (#134)

0.5.1 - 2020-08-05

Fixes

• Relative paths are now allowed in securitySchemes/OAuthFlow/tokenUrl (#130).
• Schema validation errors will no longer print a stack trace (#131).
• Invalid YAML/URL will no longer print stack trace (#128)

0.5.0 - 2020-08-05

Changes

• When encountering a problem, the generator will now differentiate between warnings (things it was able to skip past) and errors (things which halt generation altogether).

Additions

• The generator can now handle many more errors gracefully, skipping the things it can't generate and continuing with the pieces it can.
• Support for Enums declared in "components/schemas" and references to them (#102).
• Generated clients can now be installed via pip (#120).
• Support for YAML OpenAPI documents (#111)

Internal Changes

• Switched OpenAPI document parsing to use Pydantic based on a vendored version of openapi-schema-pydantic (#103).
• Tests can now be run on Windows.

0.4.2 - 2020-06-13

Additions

• Support for responses with no content (#63 & #66). Thanks @acgray!
• Support for custom string formats (#64 & #65). Thanks @acgray!

0.4.1 - 2020-06-02

Additions

• Support for Python 3.7 (#58)

0.4.0 - 2020-05-30

Breaking Changes

• Classes generated to be included within lists will now be named like Item. For example, if a property named "statuses" is an array of enum values, previously the Enum class declared would be called "Statuses". Now it will be called "StatusesItem". If a "title" attribute was used in the OpenAPI document, that should still be respected and used instead of the generated name. You can restore previous names by adding "StatusesItem" to the class_overrides section of a config file.
• Clients now require httpx ^0.13.0 (up from ^0.12.1). See httpx release notes for details.

Additions

• Support for binary format strings (file payloads)
• Support for multipart/form bodies
• Support for any supported property within a list (array), including other lists.
• Support for Union types ("anyOf" in OpenAPI document)
• Support for more basic response types (integer, number, boolean)
• Support for duplicate enums. Instead of erroring, enums with the same name (title) but differing values will have a number appended to the end. So if you have two conflicting enums named MyEnum, one of them will now be named MyEnum1. Note that the order in which these are processed and therefore named is entirely dependent on the order they are read from the OpenAPI document, so changes to the document could result in swapping the names of conflicting Enums.

Changes

• The way most imports are handled was changed which should lead to fewer unused imports in generated files.

• Better error messages

  • Most error messages will contain some useful information about why it failed instead of a stack trace
  • Client will still be generated if there are recoverable errors, excluding endpoints that had those errors

• Output from isort and black when generating will now be suppressed

Fixes

• Defaults within models dataclasses for Dict or List properties will now be properly declared as a field with the default_factory parameter to prevent errors related to mutable defaults.

0.3.0 - 2020-04-25
