V7 inheritance demo gives Typescript error

[JamieS1211]

Hi there, I have just started migrating over to sequelize 7 and have run into an issue with the example for model inheritance.

The documentation can be found here- https://sequelize.org/docs/v7/models/inheritance/

The example suggests for the abstract class to be:

@Table.Abstract
class Player<M extends Player = Player> extends Model<InferAttributes<M>, InferCreationAttributes<M>> {
  @Attribute(DataTypes.STRING)
  @NotNull
  declare name: string;
}

However when doing this I get a typescript error:

Type parameter 'M' has a circular default.ts(2716)
⚠ Error(TS2716) | 
Type parameter M has a circular default.
class Player<M extends Player<unknown>>

If you have any advice here would be fantastic as I am totally stumped. I agree with your example but it IS circular and if thats an issue for typescript not sure what to do sort of "ts-ignore" 🤮

I also encountered this problem 😞

@Table.Abstract
export abstract class Player<M extends Player<M>> extends Model<InferAttributes<M>, InferCreationAttributes<M>> {
    @PrimaryKey
    @AutoIncrement
    @Attribute(DataTypes.INTEGER)
    declare id: CreationOptional<number>;
}

@Table.Abstract
export class User<M extends TenantBase<M>> extends Player<M> {
    @NotNull
    @Attribute(DataTypes.STRING)
    declare name: string; 
}

export class Test extends UserBase<Test> {
    @NotNull
    @Attribute(DataTypes.STRING)
    declare userinfo: string; 
}

I successfully created the table using this method, but the field order is reversed.

like as :
userinfo | name | id
