this.setDataValue() does not type-check correctly inside an attribute setter

I want use ‘setDataValue’, ‘getDataValue’ in typescript,so I write in this way.

this.setDataValue('points', JSON.stringify(val)); // error

but it’s error, so I write like this.

const Model = app.model.define(
    'area',
    {
      areaId: {
        type: INTEGER,
        primaryKey: true,
        allowNull: false,
        autoIncrement: true,
      },
      name: { type: STRING(32), allowNull: false },
      points: {
        type: TEXT,
        set(val) {
          // this.setDataValue('points', JSON.stringify(val)); //error.
          Model.prototype.setDataValue.bind(this)(             //correct
            'points',
            JSON.stringify(val),
          );
        },
        get() {
          return JSON.parse(Model.prototype.getDataValue.bind(this)('points'));
        },
      },
    },
    {
      timestamps: false,
    },
  ) as IArea;

@rolandleth Thanks! You too!

Oh, I totally missed OP’s bind(this) 😞 I thought it behaves differently because I’m using classes, which is why I also thought about a different issue. Thank you for the call(this... suggestion!

Have a great Saturday, @papb!
