Struct IntermediateRelationship 

pub struct IntermediateRelationship {
    pub name: String,
    pub target_type: String,
    pub cardinality: Cardinality,
    pub foreign_key: String,
    pub referenced_key: String,
}

A relationship in intermediate format (#1266).

Reuses the compiled-schema Cardinality directly, for the reason FieldDefinition::vector reuses VectorConfig: the authored and compiled shapes cannot then drift.

foreign_key and referenced_key are SQL column names — the foreign key lives on the child table and the referenced key on the parent, whichever side of the relationship each happens to be:

cardinality	key read off the declaring type	key filtered on the target
OneToMany	referenced_key	foreign_key
ManyToOne	foreign_key	referenced_key
OneToOne	foreign_key	referenced_key

Both are required here, unlike the compiled struct where they carry #[serde(default)] — an empty join column is a relationship no embed can compose a predicate for, and an author who omits one should learn that from the parse error rather than from an empty array on a 200.

Fields

name: String

Relationship name — the key in ?select=<name>(...) and in the response.

target_type: String

Target GraphQL type name, e.g. "Post". Must be a declared type that some list query returns; the embed sources its rows from that query.

cardinality: Cardinality

OneToMany, ManyToOne or OneToOne.

foreign_key: String

Foreign key column on the child table, e.g. fk_author.

referenced_key: String

Referenced key column on the parent table, e.g. id.
