sails-grunt-task-db-migrate

sails-grunt-task-db-migrate

db-migrate integration for Sails.js. This is a fairly simple wrapper, which provides grunt tasks for running and creating migrations. It also extracts the database configuration from the Sails config, so you don't have to duplicate you config in a database.json file.

Supports Sails 0.10.x+ till Sails 1.2.4.

You don't need to install the dependencies manually. Instead, the dependencies ( like db-migrate, db-migrate-mongodb, etc... ) will be installed automatically. Before install this npm, please create config/migrations.js.

And also, this npm supports db:create, db:drop and db:seed.

Setup

Installation is very typical.

$ npm install --save sails-grunt-task-db-migrate


You need to setup `config/migrations.js` to name the connection which you will
use to run migrations.

```JavaScript
// config/migrations.js
module.exports.migrations = {
  // connection name matches a field from config/connections.js
  connection: 'default' // or MySQL
};

Optionally, you can specify in the config file the name of the database table to be used to track migrations (defaults to migrations), the directory to use for migrations (defaults to migrations), and whether to create a coffeescript file for the migrations instead of javascript file (defaults to false).

And also, we can set seedingDir option. If it is not yet set, the default path will be seeders folder under root folder.

// config/migrations.js
module.exports.migrations = {
  // connection name matches a field from config/connections.js
  connection: 'somePostgresqlServer', // or MySQL
  table: 'sails_migrations',
  migrationsDir: 'db/migrate',
  seedingDir: 'db/seeders', 
  coffeeFile: true
};

You'll also need to setup tasks/register/dbMigrate.js to add the db:migrate tasks to grunt.

// tasks/register/dbMigrate.js
module.exports = require( 'sails-grunt-task-db-migrate' ).sailsGruntTasks

npm i -S sails-grunt-task-db-migrate

grunt db:migrate:create --name=create_test_schema

grunt db:migrate:up

grunt db:migrate:down --count=150

grunt db:migrate:db:create --db-name=test_db

grunt db:migrate:db:drop --db-name=test_db

Sample seeder file

// seeders/TestTableSeeder.js or db/seeders/TestTableSeeder ( where TestTable is a model of a db table test_table )
module.exports = aysnc() {
  TestTable.create( { field1: 'value', field: 'value' } )
}
