| 17 | * Many-to-many: the parent and the related model link THROUGH a pivot | |
| 18 | * table (`Post` ↔ `Tag` via `posts_tags`). | |
| 19 | * | |
| 20 | * The relation query INNER JOINs the pivot: a parent with no pivot rows | |
| 21 | * legitimately has no related models, so INNER is the honest semantics | |
| 22 | * (the same call {@see HasManyThrough} makes). Joins are SQL-only — a | |
| 23 | * non-SQL connection throws | |
| 24 | * {@see \BlueprintAU\Radiant\Database\Exceptions\UnsupportedFeatureException} | |
| 25 | * at execution. | |
| 26 | * | |
| 27 | * The pivot table default is `{parentTable}_{relatedTable}` — deterministic | |
| 28 | * concatenation, no singularization guessing (Radiant's pluralizer is | |
| 29 | * naive; a reverse singularizer would mangle irregulars). Pass an explicit | |
| 30 | * `$table` for any other name. The pivot key columns default to | |
| 31 | * `{parentTable}_id` / `{relatedTable}_id`. | |
| 32 | * | |
| 33 | * Pivot data rides the eager select: `withPivot()` adds pivot columns to | |
| 34 | * the select (aliased `radiant_pivot_{column}`), readable per related | |
| 35 | * model through `pivotValue()`. `withTimestamps()` is sugar for the | |
| 36 | * created_at/updated_at pair. | |
| 37 | * | |
| 38 | * The write API — attach/detach/sync/toggle — operates on the pivot table | |
| 39 | * directly through the connection's plain builder (no hydration, no | |
| 40 | * events); `sync()` wraps its diff in a transaction. | |
