如何在PostgreSQL中使用Knex.js進行級聯刪除？

Question

我在嘗試刪除另一個表（頁面）引用的表（應用程序）時收到此錯誤。

knex.schema.dropTable("application").exec(); 

錯誤是

Possibly unhandled error: cannot drop table application because other objects depend on it 
at Connection.parseE (/home/balan/node_modules/pg/lib/connection.js:526:11) 
at Connection.parseMessage (/home/balan/node_modules/pg/lib/connection.js:356:17)

Answer 1

我只是原始的SQL做到這一點： return knex.raw('DROP TABLE application CASCADE');
