Variants

Standard

Standard Pylon junction table ({source_table}.{link_name}) with source uuid and target uuid columns.

Fields

junction_table: String

Unqualified junction table name, e.g. person.posts.

module: String

Schema module for quoting, e.g. default.

Through

Explicit through type with resolved FK columns.

Fields

junction_table: String

PostgreSQL table of the junction type.

module: String

Schema module of the junction type.

source_col: String

Column on the junction table that references the source type’s id.

target_col: String

Column on the junction table that references the target type’s id.

BacklinkFk

Reverse of a single (FK) link — the owner type’s rows are correlated directly by their FK column, no junction table involved. Still many-valued (several owner rows can point at the same current row), so this shares IrMultiLinkPointer’s array_agg-based emission rather than the singular IrShapePointer::Link representation.

Fields

fk_col: String

FK column on the owner (sub-select) table, e.g. org_id.

BacklinkJunction

Reverse of a multi-link — same junction table a forward Standard/ Through multi-link would use, but with the owner/current column roles swapped: the sub-select’s own rows correlate via owner_col, the current (outer) row correlates via current_col.

Fields

junction_table: String

module: String

owner_col: String

Junction column that references the owner (sub-select) type’s id.

current_col: String

Junction column that references the current (outer) row’s id.
