Sequelize database seed function

snippet.js

if(process.env.NODE_ENV !== 'production') {
  sequelize.sync({force: true}).then(() => {
    
    // Some sample projects
    var projects = {
      data: [
        {
          name: 'Kitchen',
        }, {
          name: 'Bathroom',
        },
      ],
      model: Project
    };
    
    var tasks = {
      data: [
        {
          title: 'Stain floors',
          goalDate: '2017-01-28',
          completed: false,
          projectId: 1
        },{
          title: 'Install baseboards',
          goalDate: '2017-01-30',
          completed: false,
          projectId: 1
        },
      ],
      model: Task
    };
    
    function seed(seeds) {
      return sequelize.Promise.each(seeds, (seed)=> {
        return sequelize.Promise.each(seed.data, (item) => {
          return seed.model.create(item);
        });
      });
    }
    
    seed([
        projects,
        tasks
    ]).then(() =>{
      console.log('all created');
      
      // Bring up express or any other apps you might want to do after seeding a database
    });
  });
}

This is now much more concise and available in http://npm.im/seedquelize
