###### 5- @hasMany: creates a one to many relationship. Will be fully functional next release.

###### 6- @belongsTo: creates a one to one relationship. Will be fully functional next release.

###### 7- @beforeCreate: runs function before saving model to database.

###### 8- @afterCreate: runs function after saving model to database.

###### 9- @beforeUpdate: runs function before updating model in the database.

``javascript
import { column, id, Entity } from 'orm-adapter';
@Entity()
class User {
@id()
username: string;
@column()
firstName: string;
@column()
lastName: string;
@column()
email: string;
}
`
##### That will simply create a user model using any orm or custom database connector and connection.

#### You can also create different models using different orms:

User.ts
`javascript
import { column, id, Entity } from 'orm-adapter';
@Entity()
class User {
@id()
username: string;
@column()
firstName: string;
@column()
lastName: string;
@column()
email: string;
}
`

Nerd.ts
`javascript
import { Schema, Container } from 'js-data';
import { MongoDBAdapter } from 'js-data-mongodb';
import { column, id, Entity } from 'orm-adapter';
@Entity(JS_DATA,
{ Schema: Schema,
Adapter: MongoDBAdapter,
adapterConfig: { uri: 'mongodb://localhost:27017' },
adapterName: "mongodb",
Container: Container })
class Nerd {
@id()
realName: string;
@column()
alterEgo: string;
@column()
cursh: string;
}
`

User will be created using the global orm and Nerd will be created using js-data.

@column()

// lets help our friend out.
@beforeCreate()

// Do some real work then joke a little:
console.log('You have no chance buddy.');
}
@afterCreate()
ready (data: any) {
// Do real job with the data.
console.log(data);
}

@beforeUpdate()
myMan() {
// Do some real work then joke a little:
console.log('You still have no chance buddy.')
}
@afterUpdate()
newMan (data: any) {
// Do real job with the data.

}

@beforeDelete()

}
@afterDelete()
afterRest (data: any) {
// Do real job with the data.
console.log(data);
}
