simpleschema-mongo
Mongo component of the SimpleSchema module.
This module provides a "mixin" to the main SimpleSchema classes. If you "mix" this constructor class with the main SimpleSchema class, you will end up with a class able to handle Mongodb-specific fields (that is, ObjectId
fields ).
Driver-specific Mixins
Basic schemas work really well for any database. However, it's handy to have driver-specific schemas which take into consideration driver-specific features.
Driver-specific schemas come in the form of mixins
: they are basic classes that should be "mixed in" with the main one. In order to mixin the constructor's prototypes, you will need to use SimpleDeclare - Github. See the example below on how to use it.
Functions provided
The MongoSchemaMixin overloads objects created with the following functions:
idTypeCast()
It will cast a field to Mongo's ownObjectId
type. If the field is not valid, casting will failmakeId()
Rather than using the default id creator, which by default just returns a random number, the overloadedmakeId()
will use Mongo's ownObjectId()
function. NOTE:makeId()
is available as an object method, and as a class method
A practical example
Here is a practical example on how to use MongoSchemaMixin
var Schema = require( 'simpleschema' );
var declare = require( 'simpledeclare' );
var MongoSchemaMixin = require('simpleschema-mongo')
// Mixing in Schema (the basic class) with MongoSchemaMixin
MyMongoSchema = declare( [ Schema, MongoSchemaMixin ] );
person = new MyMongoSchema({
personId: { type: 'id', required: true },
anotherId: { type: 'id', required: true },
name: { type: 'string', required: true },
});
var p = { name: 'Tony', anotherId: '529955ecd03de35b0f999991' } ;
MyMongoSchema.makeId( p, function( err, id ){
if( err ){
console.log("Error making the id:");
console.log( err );
} else {
p.personId = id;
console.log( "MADE ID IS: ", id );
person.validate( p, function( err, newP, errors){
if( err ){
console.log("Oh no!");
console.log( err );
} else {
console.log("New P:");
console.log( newP );
console.log("Errors");
console.log( errors);
}
});
}
});
