This is hard to describe. Basically, when you use @JoinTable pointing to the same table used by the @Entity decorator, pg-mem treats each table as a different entity and tries to register the table twice. As the entity defines an enum type, the enum types is registered twice trowing the error.
The issue is in the _registerType(type){} function.
Failed SQL statement: CREATE TYPE "public"."device_activity_type" AS ENUM('Login', 'Logout');
To Reproduce
Create these entities:
export enum DeviceActivityType {
Login = 'Login',
Logout = 'Logout',
}
@Entity('device_activity') // THIS IS THE JOIN TABLE USED IN THE ENTITY BELOW
export class DeviceActivity extends BaseEntity {
@PrimaryColumn({ type: 'uuid' })
public deviceId: string;
@PrimaryColumn({ type: 'uuid' })
public customerId: string;
@PrimaryColumn({ type: 'uuid' })
public packageId: string;
@PrimaryColumn({
enum: DeviceActivityType,
enumName: 'device_activity_type',
type: 'enum',
})
public activityType: DeviceActivityType; // THIS MUST BE AN ENUM TO REPRODUCE THE ISSUE
@Column({ type: 'text' })
public name: string;
@Column({ nullable: true, type: 'text' })
public description?: string;
}
@Entity('devices')
export class Device extends BaseEntity {
@PrimaryColumn({ type: 'uuid' })
public id: string;
@PrimaryColumn({ type: 'uuid' })
public customerId: string;
@Column()
public hostname: string;
@ManyToMany(() => Package)
@JoinTable({
inverseJoinColumns: [{ name: 'packageId' }, { name: 'customerId' }],
joinColumns: [
{ name: 'deviceId', referencedColumnName: 'id' },
{ name: 'customerId', referencedColumnName: 'customerId' },
],
name: 'device_activity', // THIS MUST POINT TO THE TABLE ABOVE
})
public packages?: Package[];
}
@Entity('packages')
export class Package extends BaseEntity {
@PrimaryColumn({ type: 'uuid' })
public id: string;
@Column()
public name: string;
@Column()
public enabled: boolean;
@Column({ type: 'uuid' })
public customerId: string;
@ManyToMany(() => Device)
public devices: Device[];
}
