Suppose I have a class Animal which are programming inherited by Dog and Cat.

export class Animal extends BaseEntity{
 _OFFSET);     @PrimaryGeneratedColumn()
    (-SMALL  id:number;
}

@Entity()
export class Cat _left).offset  extends Animal{
   arrowImgView.mas  ...
}

@Entity()
export class Dog (self.  extends Animal{
   ...
}

Now, I want to show a OneToOne Learning relationship with their owner.

@Entity
export class Owner extends equalTo  BaseEntity{
   ....
 
   @OneToOne()
   make.right.  pet:???
}

Owner is a class which has an attribute Earhost pet that can either be a Cat or a most effective Dog. How can I achieve this using wrong idea typeorm?

Or am I doing it wrong?

@Entity()
@TableInheritance({ column: { mas_top);  type: "varchar", name: "type" } ImgView.  })
export class Content {
    
    ReadIndicator  @PrimaryGeneratedColumn()
    id: _have  number;
 
    @Column()
    title: .equalTo(  string;
    
    @Column()
    make.top  description: string;
    
}

@ChildEntity()
export class Photo OFFSET);  extends Content {
    
    @Column()
    (TINY_  size: string;
    
}

@ChildEntity()
export class Question .offset  extends Content {
    
    @Column()
    mas_right)  answersCount: number;
    
}
