javascript - Strongloop EmbedsMany helper methods not found -

some questions can't find answer in documentation.

i'm trying structure this:

 node:     id: '1sdf12asd123',    name: 'node1',    history:        [ ts: 234234234234,         data: { 'foo': 'bar' }       ],       ... 

so each individual node, has many history items. , want able push new data that, without overwriting anything.

now, don't want store under each node, rather in seperate document, think embedsmany suitable this:

{   "name": "node",   "plural": "nodes",   "base": "persistedmodel",   "idinjection": true,   "options": {     "validateupsert": true   },   "properties": {     "name": {       "type": "string"     }   },   "validations": [],   "relations": {     "history": {       "type": "embedsmany",       "model": "history",       "foreignkey": "historyid"     }   },   "acls": [],   "methods": {} } 

so history simply:

{   "name": "history",   "base": "persistedmodel",   "idinjection": true,   "properties": {     "ts": {       "type": "date"     },     "data": {       "type": "object"     }   },   "validations": [],   "relations": {     "node": {       "type": "belongsto",       "model": "node",       "foreignkey": "nodeid"     }   },   "acls": [],   "methods": {} } 

i'm not sure foreignkey part right, i've tried lot of different combinations, , 1 seems logical.

the history model not public, not exposed endpoint. , want utilize relations as possible, rather have seperate endpoint.

main issue here use nodes.history.add() described here.

but i've tried different methods remote methods operation hooks, can't find helper methods mentioned. there's no code example found this.

partly think because documentation @ times not clear or assumes degree of knowledge how perhaps other api-frameworks work. , i've read every page of documentation found. (one example core concepts page links deprecated model hooks page.)

what i'd know:

1. is idea of using .add() right push data on model, , have loopback manage should store it, when query node i'd history items, unless prevent on server side (because wouldn't want every request node data itself.
2. is idea create separate document each history item, nodeid in it, or better make 1 histoy item per node, , store history inside them? main issue me is, how push data, without overwriting anything, , perhaps utilizing timestamp key?
3. does history model need know relation nodes belongsto or oblivious , still have nodes .add() each history item it?

if understand problem correctly, instead node hasmany history. use methods generated relation :

to create new history using relation

post api/node/{nodeid}/histories/  

you should able create multiple instances of history single post request writing json data appropriately

{     {        ts: 26283829879     },     {        ts: 5335329923     } } 

to single histories node

get api/node/{nodeid}/histories/{historyid}/ 

you can histories node, edit history of given node, etc.

is helpful ?

see strongloop docs hasmany relations.
