How to use cascade with a multi-column foreign key?

When using references I can tell a foreign key to cascade on a delete easily. However: I have a table with a composite primary key:
const items = pgTable(
'items',
{
id: integer('id').notNull(),
hotelId: integer('hotel_id')
.references(() => hotels.id, CASCADE)
.notNull(),
// ...other fields
},
(table) => ({
pk: primaryKey(table.id, table.hotelId)
})
);
const items = pgTable(
'items',
{
id: integer('id').notNull(),
hotelId: integer('hotel_id')
.references(() => hotels.id, CASCADE)
.notNull(),
// ...other fields
},
(table) => ({
pk: primaryKey(table.id, table.hotelId)
})
);
and a table referencing that table with a composite foreign key:
const addresses = pgTable(
'client_item_addresses',
{
itemId: integer('item_id').notNull(),
hotelId: integer('hotel_id').notNull(),
// ...other fields
},
(table) => ({
pk: primaryKey(table.itemId, table.hotelId),
fk: foreignKey({
columns: [table.itemId, table.hotelId],
foreignColumns: [items.id, items.hotelId]
})
})
);
const addresses = pgTable(
'client_item_addresses',
{
itemId: integer('item_id').notNull(),
hotelId: integer('hotel_id').notNull(),
// ...other fields
},
(table) => ({
pk: primaryKey(table.itemId, table.hotelId),
fk: foreignKey({
columns: [table.itemId, table.hotelId],
foreignColumns: [items.id, items.hotelId]
})
})
);
How do I activate cascade on delete in this scenario?

oh, that's a nice feature request we don't have this option now and should definitely add it

I see, no problem! Haven't had a look at the codebase yet, but do you think this would be a doable first contribution?

This is an easy one because the underlying class already supports it. You just need to accept the parameter in the function. This a nice first contribution
