Neo4j Graph Data Model
===


Also works with new bolt driver

Changes
===

3.2.0 : allow setRelationship & set to be used with simple object and not just Model instance or id

breaking: v3 no longer relies on neo4j id's and sets own id property if not set in model declaration

Usage
===

Setup
---
``js
const NeoDM = require('neodm');
NeoDM.db.setDB('http://localhost:7474');
NeoDM.db.setLogger(console.log);
`

Model Declaration
---
`js
const Joi = require('joi');
const Model = NeoDM.Model;
`

Simple model declaration
---
`js
class User extends Model {
static [Model.schema]() {

return {
username: Joi.string()
};
}
}

const johnData = { username: 'john' };
const john = new User(johnData);
yield john.save();
`

hasOne relationship
---
`js
class User extends Model {
static [Model.schema]() {

return {
username: Joi.string()
};
}

}

class Article extends Model {
static [Model.schema]() {

return {
title: Joi.string().default('test'),
author: Model.hasOne(User)
};
}
}

const johnData = { username: 'john' };
const john = new User(johnData);
yield john.save();


const article = new Article({ title: 'hello world', author: john });
yield article.save();

`

find( {property:value, anotherProp:value} )
---
`js

class User extends Model {
static [Model.schema]() {

return {
username: Joi.string()
};
}

}

const johnData = { username: 'john smith' };
const john = new User(johnData);
yield john.save();

const johnFromDB = yield User.find({ username: johnData.username });
`

find( [ id1, id2 ] )
---
`js
const john = new User({ username: 'john' });
yield john.save();

const smith = new User({ username: 'smith' });
yield smith.save();

const users = yield User.find([smith.id, john.id]);
`

Full Model Declaration
---
`js
class Author extends Model{
static [Model.schema](){
return {
name:Joi.string()
}
}

afterInit(){

//no return
}

afterInflate(inflatedRelationshipKeys){

return Promise;
}

beforeValidate(){

return Promise;
}
}
