is there a reason why we dont want to use the same logic? Like
"partition-spec": self._spec.model_dump_json(),

Unfortunately the spec.fields returns a list, which is not a Pydantic object, but a native Python construct. So the method isn't available.

this is 👍 since the version function is defined

| "partition-spec": spec.model_dump_json(), | ||
| "partition-spec-id": str(spec.spec_id), | ||

is it possible to not hardcode this value?

I actually like that we are hardcoding this value because the issue wasn't caught because we inferred it from test_spec before :)

I prefer to hardcore the expected value so it is clear what is being returned when you go over the tests.

Sorry for being late here. @Fokko Great catch! Thanks for fixing this and the refactoring :). @syun64 @kevinjqliu Thanks for reviewing!
Related to projectnessie#9042, Iceberg's `o.a.iceberg.ManifestReader.ManifestReader()` extracts the partition spec either via a provided `Map<Integer, PartitionSpec>` or re-constructs it from Avro metadata attributes. pyiceberg until including version 0.6.1 however writes _invalid_ manifest files (see apache/iceberg-python#846) with the `partition-spec` Avro metadata attribute containing the JSON of the whole partition-spec instead of just the partition-spec fields. This change propagates the mentioned map down to the manifest-reader to work around this pyiceberg issue.

It should write the fields instead of the full spec: #208 (comment)
Also, did a small OOP refactor.
