Breaking Changes
- Raise minimum httpx version to 0.23
Removed ability to set an array as a multipart body
Previously, when defining a request's body as multipart/form-data, the generator would attempt to generate code
for both object schemas and array schemas. However, most arrays could not generate valid multipart bodies, as
there would be no field names (required to set the Content-Disposition headers).
The code to generate any body for multipart/form-data where the schema is array has been removed, and any such
bodies will be skipped. This is not expected to be a breaking change in practice, since the code generated would
probably never work.
If you have a use-case for multipart/form-data with an array schema, please open a new discussion with an example schema and the desired functional Python code.
Change default multipart array serialization
Previously, any arrays of values in a multipart/form-data body would be serialized as an application/json part.
This matches the default behavior specified by OpenAPI and supports arrays of files (binary format strings).
However, because this generator doesn't yet support specifying encoding per property, this may result in
now-incorrect code when the encoding was explicitly set to application/json for arrays of scalar values.
PR #938 fixes #692. Thanks @micha91 for the fix, @ratgen and @FabianSchurig for testing, and @davidlizeng for the original report... many years ago 😅.
