How to seed dev database in Sails.js in a reproducible way - sails.js

Question

I'm looking for a best way to seed my development database in sails js.
In rails I would just use the seeds.rb file but even without that I could use a rake task.
With sails I am unsure of how I could do this outside of manually doing it with sails console.
Please note that solutions which add logic to config/models and the models themselves for production seeding are not what I am looking for. I don't want these records to exist in production.

Answer 1

You can seed your database in the config/bootstrap.js file.
To seed it for a particular environment, what I usually do is:
// config/bootstrap.js
module.exports.bootstrap = function (cb) {
if(process.env.NODE_ENV !== 'development')
return cb();
// Do whatever you want
// And don't forget to...
return cb();
};
And to drop the database each time during the Sails lifting:
// config/env/development.js
module.exports = {
models: {
migrate: 'drop'
}
};

You can use test framework, like Mocha. At your development mode, switch your table name to development table. Here is step by step:
Install mocha with npm install mocha --save-dev
Create test/boostrap.test.js and fill with (configure as your needs), look at my configured connections, it'll override default connections at config.
var Sails = require('sails'),
sails;
before(function (done) {
Sails.lift({
log : {
level: 'error'
},
connections: {
mongodbServer: {
database: 'table_test'
}
},
models : {
migrate: 'drop'
}
}, function (err, server) {
sails = server;
done(err, sails);
});
});
after(function (done) {
// here you can clear fixtures, etc.
sails.lower(done);
});
Create another file for seeding your data, for example create test/inject/seed.js and fill with something like.
describe('data seeding', function(){
it('should seed data', function(done){
sails.models.someModel
.create({
name: 'Some Name'
})
.then(function(result){
done();
})
.catch(done);
});
});
Add this at your package.json under "scripts" key.
"test": "_mocha test/bootstrap.test.js test/inject/**/*.inject.js --no-timeouts"
Run it with npm test to seed your data.
If you need to use it at development mode, when you run sails lift, edit your config/env/development.js and add something like this.
module.exports = {
connections: {
mongodbServer: {
database: 'table_test'
}
}
};
Now your sails lift will use table_test instead of production table, so your production table will be clean.
