sequelize association include code example

Example 1: sequelize include only

Payment.findAll({
    where: {
        DairyId: req.query.dairyid
    },
    attributes: {
        exclude: ['createdAt', 'updatedAt']
    },
    include: {
        model: Customer,
        attributes:['customerName', 'phoneNumber']
    }
})

Example 2: sequelize associations

const User = sequelize.define('user', { name: DataTypes.STRING }, { timestamps: false });
const Task = sequelize.define('task', { name: DataTypes.STRING }, { timestamps: false });
const Tool = sequelize.define('tool', {
  name: DataTypes.STRING,
  size: DataTypes.STRING
}, { timestamps: false });
User.hasMany(Task);
Task.belongsTo(User);
User.hasMany(Tool, { as: 'Instruments' });


//access the model
const tasks = await Task.findAll({ include: User });

//output

[{
  "name": "A Task",
  "id": 1,
  "userId": 1,
  "user": {
    "name": "John Doe",
    "id": 1
  }
}]
