I would like to populate my mongo with some test data.
I have defined mongoose models and I was wandering if it was possible to pragmatically create mongo documents using pre defined models.
For example, model Items
var Schema = mongoose.Schema;
var Items = new Schema({
title: { type: String, required: true },
desc: { type: String}
});
Sure, do it in a single-purpose node app. Create a new app that doesn't use express or whatever web framework, but instead just has your model definition and a connection to your database.
You'll need a data source of course for the test data, which you could just use a random word generator, like this one: http://james.padolsey.com/javascript/random-word-generator/
function createRandomWord(length) {
var consonants = 'bcdfghjklmnpqrstvwxyz',
vowels = 'aeiou',
rand = function(limit) {
return Math.floor(Math.random()*limit);
},
i, word='', length = parseInt(length,10),
consonants = consonants.split(''),
vowels = vowels.split('');
for (i=0;i<length/2;i++) {
var randConsonant = consonants[rand(consonants.length)],
randVowel = vowels[rand(vowels.length)];
word += (i===0) ? randConsonant.toUpperCase() : randConsonant;
word += i*2<length-1 ? randVowel : '';
}
return word;
}
Then you'd need to populate the database like this:
var numTestDocs = 100; // or however many you want
for(var i = 0; i < numTestDocs; i++) {
var someLength = 12; // Alternatively, you could use a random number generator
var randomWord = createRandomWord(someLength);
var item = new Item ({
title : randomWord ,
desc : randomWord + ' is just a test'
});
item.save(function(err, doc) {
// do error handling if you want to
console.log('Test Record Saved with id: ' + doc._id);
});
}
Then just run that node app.
There are many ways to do this using different mongoose modules. Go and check mongoose fakery.
