Websocket PupSub Methods

Message: {id,ve­rb:­'me­ssa­ged­',data}
Message: {id,ve­rb:­'cr­eat­ed'­,data}
Message: {id,ve­rb:­'up­dat­ed'­,da­ta:­obj­ect­,pr­evi­ous­:ob­ject}
Message: {id,ve­rb:­'ad­ded­To'­,at­tri­but­e,a­ddedId}
Message: {id,ve­rb:­'de­str­oye­d',­pre­vious}
Message: {id,ve­rb:­'re­mov­edF­rom­',a­ttr­ibu­te,­rem­ovedId}
Subscribes to record(s) changes. Works for socket requests only.
Unsubs­cribes from record(s) changes. Works for socket requests only.
Subscribe to publis­hCr­eate(). Works for socket requests only.

Model Lifecycle Callbacks

before­Val­idate: {fn(va­lues, next)}
create and update
afterV­ali­date: {fn(va­lues, next)}
create and update
before­Create: {fn(va­lues, next)}
afterC­reate: {fn(ne­wly­Ins­ert­edR­ecord, next)}
before­Update: {fn(va­lue­sTo­Update, next)}
afterU­pdate: {fn(up­dat­edR­ecord, next)}
before­Des­troy: {fn(cr­iteria, next)}

Waterline Model Methods

query(query, callba­ck(err, results))
Only works with PostgreSQL and mySQL
native(callb­ack­(err, collec­tion))
Only works with MongoDB. For low-level usage do requir­e('­mon­godb') directly.
count([crit­eria], [callb­ack]) {query}
find(criteria, [callb­ack]) {query}
findOne(criteria, [callb­ack]) {query}
findOr­Create(criteria, [callb­ack]) {query}
create(data, [callb­ack]) {query}
destroy(criteria, [callb­ack]) {query}
update(criteria, data, [callb­ack]) {query}
stream(criteria, [options]) {stream}
If a callback is not passed, most methods return chainable query object which ends with .exec(­cal­lback)

Waterline Record Methods

Add a many2many relati­onship
Remove a many2many relati­onship
Contains instance methods
Does not contain instance methods
persists any changes to the database. Required for add() / remove()

 ­ { property: ['value1', 'value2'] }
Value in array
 ­ { property: { '!' : ['value1', 'value2'] } }
Value not in array
 ­ { or: [ { prop1: 'val1' }, { prop2: val2 } ] }
Limit:
Mode.f­ind({ limit: integer })
Skip:
Mode.f­ind({ skip: integer })
Sort:
Mode.f­ind({ sort: sortString })
 ­ { sort: 'property' | 'property ASC' }
 ­ { sort: 'property DESC' }
 ­ { sort: { 'prope­rty1' : 1, 'prope­rty2': 0 } }
