Usage

Configure

// config/main.js
module.exports = {
  // ...
  packs: [
    require('trailpack-sequelize')
  ]
}

A basic config/database.js can be found here : https://github.com/trailsjs/trailpack-sequelize/blob/master/archetype/config/database.js

Models

module.exports = class User extends Model {
  //More about supported schema here : http://docs.sequelizejs.com/en/latest/docs/models-definition/
  static schema (app, Sequelize) {
    return {
       name: { type: Sequelize.STRING, allowNull: false },
       password: Sequelize.STRING,
       displayName: Sequelize.STRING
     }
  }

  static config (app, Sequelize) {
    return {
       migrate: 'drop', //override default models configurations if needed
       store: 'sqlite', //override default models configurations if needed
       //More informations about supported models options here : http://docs.sequelizejs.com/en/latest/docs/models-definition/#configuration
       options: {
         classMethods: {
           //If you need associations, put them here
           associate: (models) => {
             //More information about associations here : http://docs.sequelizejs.com/en/latest/docs/associations/
             models.User.hasMany(models.Role, {
               as: 'roles',
               onDelete: 'CASCADE',
               foreignKey: {
                 allowNull: true
               }
             })
           }
         }
       }
     }
  }
}

Query

// api/services/UserService.js
module.exports = class UserService extends Service {
  /**
   * Finds people with the given email.
   * @return Promise
   * @example {
   *    name: 'Ludwig Beethoven',
   *    email: '[email protected]',
   *    favoriteColors: [
   *      { name: 'yellow', hex: 'ffff00' },
   *      { name: 'black', hex: '000000' }
   *     ]
   * }
   */
  findUser (email) {
    //More info about queries here : http://docs.sequelizejs.com/en/latest/docs/models-usage/
    return this.app.orm.User.find({ where: {email: email} })
  }
}

For more informations about sequelize queries, please look at the official documentation

Footprints query options

Some options can be provide as query param for the find method, example GET /api/v1/user.

Populate

You can add /api/v1/user?populate=all to populate all associations or use /api/v1/user?populate=field1,field2 to populate only some association.

Pagination

By settings offset and limit you can do some pagination, example /api/v1/user?offset=10&limit=10 will return only 10 items started from 10 (id 10 to 20).
