Re-use a smart field logic

This example shows you how to re-use the logic of your smart field.
Here, we created a fullname field that concatenates first and last name. We'll create our own function and export it for use elsewhere in our admin backend.
Requirements
An admin backend running on forest-express-sequelize
How it works
Directory: /models
This directory contains the users.js where the model is defined. 
/models/users.js
module.exports = (sequelize, DataTypes) => {
  const { Sequelize } = sequelize;
​
  const Users = sequelize.define('users', {
    firstName: {
      type: DataTypes.STRING,
    },
    lastName: {
      type: DataTypes.STRING,
    },
  }, {
    tableName: 'users',
    timestamps: false,
    schema: process.env.DATABASE_SCHEMA,
  });
​
  return  Users;
};
Directory: /forest
This directory contains the users.js file where the Smart Field fullnameis declared.
const { collection } = require('forest-express-sequelize');
​
// create our own module
const getFullname = (user) => {
  return `${user.firstName} ${user.lastName}`;
};
​
​
collection('users', {
  fields: [{
    field: 'fullname',
    type: 'String',
    get: getFullname,
  }],
});
​
// export it to use it somewhere else in our admin backend
module.exports = {
  getFullname,
};
You can now require this module everywhere in your admin backend:
const { getFullname } = require('../forest/user');
