fix(gooddata-api-client): accept primitive-only oneOf union values - #1934
Reading or writing a workspace no longer fails on a Publisher document whose style carries a number or a string, such as gap: 20, by teaching the generated client's templates to accept the member values of primitive-only oneOf unions. The SDK's document model is unchanged: a document's content stays an opaque dict.
Every page the Reports UI adds from an "N visualizations" layout writes style.gap: 20. Once a workspace held one, get_declarative_analytics_model, get_declarative_workspace, store_declarative_analytics_model and gdc clone failed, and so did the write side (from_dict, load_from_disk, to_api, put, gdc deploy):
ApiTypeError: Invalid type for variable 'gap'. Required value type is PublisherDocumentAreaStyleGap and passed type was int
The spec types these fields as a oneOf of two primitives, and python-prior v6.6.0 renders such a schema as an empty model class that accepts no value. Seven classes are affected, not only gap and padding:
PublisherDocumentAreaStyleGap number | string
PublisherDocumentContainerStylePadding number | string (paddingTop/Right/Bottom/Left too)
PublisherDocumentContainerStyleBorderBottomLeftRadius number | string (every border*Radius)
PublisherDocumentAutoVisibilityVisible boolean | string (display.dataLabels, display.dataPoints)
PublisherDocumentDateFilterDateFilterFrom string | number (from/to)
DashboardDateFilterDateFilterFrom string | int32 (tabular export date filter from/to)
ConditionalFormattingLiteral string | number
After the change a member value goes in and comes back unchanged, 20 as the int 20, 4.5 as 4.5 and a theme token as that string. A dict, a list, or a bool on a number union is still an ApiTypeError. Genuinely empty object models (JsonNode, ColumnLocation, DependsOnItem) and plain number properties behave as before, and regenerating from the specs already in schemas/ gives a diff of the seven union models and model_utils.py only.
The four commits, in order:
fix(gooddata-api-client): the template change, the regenerated client and the client-level union tests;
test(gooddata-sdk): style values in the document unit tests and a test that deserializes a layout body the way a response is deserialized;
test(gooddata-sdk) and chore(gooddata-sdk): the recorded document round trip seeds the same style values, and its cassette is re-recorded on its own.
Decisions
The fix lives in the generator templates, not in the SDK.
The templates are what the client is generated from, so the fix survives make api-client and repairs the client for every caller, the raw client included.
Unchecked construction in the SDK would take validation off the whole layout and leave the client broken for everyone else.
Narrowing the spec is wrong, because both members are real: numbers are canvas px and strings are theme tokens.
A primitive-only oneOf model is marked with its member types, and only the templates can see that.
A non-empty oneOf list in the codegen model is the one thing that tells such a union from a genuinely empty object model, so model_normal.mustache:47 emits _primitive_oneof_types on exactly these seven classes, and get_possible_classes validates a property against those types.
The override is a full copy of the upstream v6.6.0 partial, to be reconciled on a generator upgrade by the procedure in .openapi-generator/README.md. A move to generator v7's python generator, which emits real unions, would retire it.
Ints stay ints.
On a union that contains float, int is admitted too, since an OpenAPI number includes integers, and validate_and_convert_types skips the int-to-float upconversion when a marked union is among the required types. So gap: 20 stays 20 through a read, the constructor, the wire and the SDK round trip, and a read followed by a put leaves the document's numbers as written.
Upconversion elsewhere is unchanged: AnomalyDetectionRequest(sensitivity=2) still becomes 2.0.
Live constraint, recorded in a template comment: a future union with a format: date string member would skip string-to-date conversion. No current union has one.
The SDK document model stays an opaque dict, as LX-3447 settled. The SDK needs no source change, only tests.
Worth a tighter look: the two hunks of model_utils.mustache, and the hand-built document in the period test, which now takes its content in the in-memory form (client python names), because the new multi-word style keys (borderRadius, dataLabels) differ between the API form and the in-memory form.
One behavior to know: for the conditional-formatting literal a wrong type surfaces as an ApiValueError that wraps the ApiTypeError, because its host ConditionalFormattingLiteralValue is a composed model and the generator wraps every allOf member error that way. The test walks the cause chain.
What comes next
Nothing is deferred in this PR. Migrating to generator v7's python generator, STRING analytics parameters (a different oneOf limitation) and typing a document's content in the SDK stay out of scope.
Test plan
test_composed_oneof_unions.py covers each of the seven unions through response deserialization and the constructor: every member type survives with to_dict() returning it unchanged (20 as the int 20), and a wrong type is rejected. It also pins that a non-union number property still upconverts an int and that an empty object model still takes a free-form object.
test_documents_survive_store_load_and_put seeds a real backend round trip with a page gap: 20, a container padding token, a borderRadius: 4.5 and a visualization display.dataLabels.visible: "auto", and asserts the read-back gap is the int 20. Its cassette is re-recorded on the SDK's staging environment, as is, with the metric and visualization permission flags off like the other document cassettes. No other cassette or fixture changes.
To verify: make -C packages/gooddata-sdk format-fix lint-fix type-check and TEST_ENVS=py314 make -C packages/gooddata-sdk test, then TEST_ENVS=py314 make -C packages/gooddata-pandas test as the consumer of the shared client. Both suites pass on py314; the py310–py313 matrix was not run.
Risk
low — the generated client is shared by every package, but the change is confined to the seven union models and to two conditions in model_utils that only a marked union reaches. Revert: full — the client is regenerated from the unchanged specs, so reverting the PR restores the previous client and the tests; nothing is migrated or written to a backend.
Improved handling of primitive values in API models, including mixed numeric and string types, so valid values are preserved and invalid values are rejected.
Preserved document styling values, such as spacing, padding, and border radius, when documents are loaded, stored, and converted.
Tests
Expanded coverage for primitive model values and document round-tripping, including exact value types and nested styling.
A declarative read failed with `ApiTypeError: Invalid type for variable
'gap'` once any Publisher document, document template or page template
in the workspace carried a style value such as `gap: 20` or
`padding: "{theme.spacing.padding.normal}"`. The write paths (from_dict,
load from disk, to_api, put) failed the same way.
The spec types these fields as a oneOf of two primitives. python-prior
v6.6.0 renders such a schema as an empty model class that accepts no
value, so all seven of them were broken: the publisher style gap,
padding and border radius, a visualization's auto-visibility, the
publisher date filter bounds, the dashboard tabular export date filter
bounds and the conditional-formatting literal.
The fix is in the custom templates, so it survives regeneration:
- an override of the normal-model partial marks a primitive-only oneOf
model with its member types (a non-empty oneOf list is the only thing
telling it apart from a genuinely empty object model);
- model_utils validates such a property against the member types, also
admits an int on a union that contains float, and skips the
int-to-float upconversion for these unions only, so 20 stays 20
through a read, the constructor and the wire.
A wrong type, such as a dict, a list or a bool on a number union, is
still rejected. Empty object models and plain number properties behave
as before. The client is regenerated from the specs already in
schemas/, so the generated diff is the seven union models and
model_utils alone.
The override is a full copy of the upstream partial and must be
reconciled on a generator upgrade; a move to generator v7's python
generator, which emits real unions, would retire it.

The document unit tests carried no style, so nothing in the SDK suite
exercised the number-or-string unions a real Publisher document uses.
Their literal now has a page `gap: 20`, a container padding theme
token, a `borderRadius: 4.5` and a visualization's
`display.dataLabels.visible: "auto"`, in the document as well as in the
document and page templates.
The round-trip assertions compare types as well as values, because
`==` treats 20 and 20.0 as equal and would not notice an int turned
into a float. A new test deserializes a layout body the way an API
response is deserialized and builds the SDK layer from it, which is
the path the reported read failure took.
The hand-built document in the period test now takes its content in
the form a read holds it, with the client's python names for the keys
the client models, as for any document's content in memory.

…trip
The recorded document store-load-put test seeded a document without any
style, so the real-backend round trip never carried the number-or-string
values a Publisher document has. The seed layout now has a page
`gap: 20`, a container padding theme token, a `borderRadius: 4.5` and a
visualization's `display.dataLabels.visible: "auto"`. The test asserts
that the read-back page keeps `gap` as the int 20 and the padding as the
token string.
The test fails on replay until its cassette is re-recorded against the
backend with the new seed.

The recorded document store-load-put test now seeds a page gap, a
container padding token, a border radius and a visualization data
label setting, so its cassette is recorded again on the SDK's staging
environment, as is and unedited. The read responses carry the page
`gap` as the JSON int 20 and the padding as the token string.
The recording was made with the metric and visualization permission
flags off, like the other document cassettes. No other cassette
changes.

The generated Python models now declare primitive oneOf member types. Model utilities use this metadata during type selection and validation. Catalog fixtures and tests cover styled analytics documents, response deserialization, and round trips that preserve exact Python types.
Changes: Primitive oneOf values in declarative documents
Layer / File(s)
Summary
Primitive oneOf generation and validation .openapi-generator/custom_templates/model_templates/model_normal.mustache, .openapi-generator/custom_templates/model_utils.mustache, gooddata-api-client/gooddata_api_client/model/*, gooddata-api-client/gooddata_api_client/model_utils.py, packages/gooddata-sdk/tests/catalog/unit_tests/test_composed_oneof_unions.py
The generator template and generated models declare primitive oneOf member types. Model utilities use those types as candidates and skip optional coercion for primitive unions. Regression tests cover accepted values, rejected values, and existing conversion behavior.
Fixtures add styled layouts, visualization values, and template metadata. Round-trip tests check exact Python types and values, including after API response deserialization.
The change is mergeable with owner awareness of two narrow configuration and response-type edge cases. Ordinary primitive-union round trips remain covered by the supplied tests.
