typeorm: auto generated UUID in postgresql
Try:
@PrimaryGeneratedColumn("uuid")id: string;Also, if you don't need a primary column, but need to generate uuid sequence, you can try this:
@Column()@Generated("uuid")uuid: string;
As of Typeorm version 0.1.16, the decorator @PrimaryGeneratedColumn supports uuid for all databases.
Usage:
@Entity()class MyClass { @PrimaryGeneratedColumn('uuid') id: string;}If your version of Postgres doesn't already include uuid-ossp (used to generate the UUID), you can install it using create extension "uuid-ossp";.
for me, I use this shape
@PrimaryGeneratedColumn('uuid') id: stringwe can use another shapeyou should install the UUID package
@PrimaryColumn() id:stringand used the @BeforeInsert() genarate(){ this.id=uuid()
