could not process model nullenum

[NANASHI0X74]

Describe the bug
I just wanted to try out generating some client code in dart against our backend, but running the openapitools generator, I get an unhelpful error: Could not process model 'NullEnum'.Please make sure that your schema is correct! (see end of output below). I tried a few other generators too and got the same error

To Reproduce

manage.py spectacular > openapi-spec.yml

generator command run and output

~/Documents/prewoe_backend> openapi-generator-cli generate -i app/openapi-spec.yml -g dart -o sample-generated.dart

Expected behavior
The generator generates some code or tells me what i can do to make it work 😅

Not sure if I should rather file this issue on the codegenerator or if I'm doing something wrong, but I thought maybe someone here can help me understand this exception

Hi @NANASHI0X74 , so first of all, all those Multiple schemas found are "normal" and can be ignored

the last release contained a feature that models null=True and blank=True on choice fields.

    B:
      type: object
      properties:
        language:
          nullable: true
          oneOf:
          - $ref: '#/components/schemas/LanguageEnum'
          - $ref: '#/components/schemas/BlankEnum'
          - $ref: '#/components/schemas/NullEnum'
      required:
      - language
    BlankEnum:
      enum:
      - ''
    LanguageEnum:
      enum:
      - en
      - es
      - ru
      - cn
      type: string
    NullEnum:
      enum:
      - null

apparently the generator does not like the NullEnum even though that is most likely the correct schema. you can run ./manage spectacular --validate --file foo.yaml to run the schema validation. The specification says that nullable: true AND - null as choice must be present. the last i checked the typescript-fetch target did in fact accept it.

its a unfortunate situation where a "proper" schema lets the generator bail.

@NANASHI0X74 with the latest openapi-generator version from docker and target dart it does not throw errors for me. i used the tests/test_postprocessing.yml which does contain above example with NullEnum and BlankEnum

can you test with the latest generator?

ok, it works with version 4.3.1. I'd tried version 4.2.2 and a snapshot of 5.0.0.
Closing, thanks :)

[tfranzel]

awesome! let me know if generated client is functioning properly with regards to this Enum thing.

[NANASHI0X74]

At the moment, the dart generator doesn't support oneof properly :(
see OpenAPITools/openapi-generator#3965 OpenAPITools/openapi-generator#3884
I realized that a bit late, even though the code doesn't even compile :/

[NANASHI0X74]

I guess I'll try version 0.9.14 instead

[NANASHI0X74]

still doesn't work, but now it throws a different error:

[NANASHI0X74]

almost works with openapitools version 4.2.2, but then there's no method Object.listFromJson :/
Now I'm kind of at my wit's end 😬

[tfranzel]

ok so first of all i would recommend using version v5.0.0, either the snapshot or the most recent beta, i.e. openapi-generator v5.0.0-beta2. it has a lot of improvements over 4.x. at least that is my experience.

i have noticed that this feature also made some trouble for us. it might be better to make it optional via setting. even though the schema is technically "more" correct like this, it is a meaningless win if it breaks the clients.

we employ oneOf etc at several locations. you might have been lucky avoiding these other ones. once you use anything polymorphic there is no way around it, but that might just not be the case for you.

[NANASHI0X74]

yeah I had the same thought that it would be handy to have a cli switch or something to switch off the null/blankenum stuff

The issues and related PRs for dart are still open, so I don't think switching to a newer version will really help me, For now I think I'll just take the parts that I really need right now from the generated code and whack them into shape manually :p

[tfranzel]

i see. makes sense. it would prob be easier just remove those parts in the schema. may be easier than editing the client.

i will deal with this asap.

[lsaavedr]

please make this feature optional T_T

[tfranzel]

@lsaavedr @NANASHI0X74 . generally, i try to make the schema as accurate as possible by default (regardless of generators). after that i try to provide options to make the client-generator usable. just as a rationale for the default ON choice.

please confirm that this works as expected
