CollectionDataFieldSlug

CollectionDataFieldSlug<TFields, TTimestamps> = DataFieldSlug<TFields> | TTimestamps extends false ? never : "updatedAt"

Defined in: packages/core/src/collections/types.ts:432

Field slugs valid wherever a collection’s OWN data-field slugs are accepted in its admin/index config (admin.view.sort/columns, admin.views[].state, indexes[].fields) — DataFieldSlug<TFields> PLUS the updatedAt defineCollection auto-injects into every collection’s fields record, UNLESS the collection opts out with timestamps: false (TTimestamps extends false). TFields never contains updatedAt at the type level — defineCollection’s own signature rejects hand-declaring it (the reserved-key guard) — so the injection is the only place that key can come from, and DataFieldSlug<TFields> alone can never see it.

Type Parameters

Section titled “Type Parameters”

TFields

Section titled “TFields”

TFields

The collection’s own literal fields record, as authored (never including the injected key).

TTimestamps

Section titled “TTimestamps”

TTimestamps extends boolean = true

The literal timestamps option defineCollection was called with — const-inferred at the call site, defaulting to true to match the runtime default (inject unless explicitly opted out).
