new CollectionApi()
A restmod collection is an extended array type bound REST resource route.
Every time a new restmod model is created, an associated collection type is created too.
TODO: talk about fetch/refresh behaviour, lifecycles, collection scopes, adding/removing
For $fetch
on a collection:
- before-fetch-many
- before-request
- after-request[-error]
- after-feed (called for every record if no errors)
- after-feed-many (only called if no errors)
- after-fetch-many[-error]

Methods
-
$action() → {CommonApi}
-
Registers a new action to be executed in the promise queue.
Registered pending actions can be canceled using
$cancel
$cancel
will also cancel any ongoing call to$send
(will not abort it yet though...)- Inherited From:
- Source:
- module/api/common-api.js, line 413
Returns:
self
- Type
- CommonApi
-
$add(_obj) → {CollectionApi}
-
Adds an item to the back of the collection. This method does not attempt to send changes to the server. To create a new item and add it use $create or $build.
Triggers after-add callbacks.
Parameters:
Name Type Description _obj
RecordApi Item to be added

- module/api/collection-api.js, line 150
Returns:
self
- Type

-
$always(_fun) → {CommonApi}
-
Promise chaining method, similar to then but executes same callback in success or error.
Usage:
col.$fetch().$always(function() { });
Parameters:
Name Type Description _fun
function success/error callback

- Source:
- module/api/common-api.js, line 314

$asPromise() → {promise}
-
Returns this object last promise.
If promise does not exist, then a new one is generated that resolves to the object itsef. The new promise is not set as the current object promise, for that use
$then

col.$fetch().$asPromise();

$build(_init) → {RecordApi}

Executes a given hook callbacks using the current dispatcher context.
This method can be used to provide custom object lifecycle hooks.
Usage:
var mixin = restmod.mixin({ triggerDummy: function(_param) { this.$dispatch('dummy-hook', _param); } }); // Then hook can be used at model definition to provide type-level customization: var Bike $resmod.model('/api/bikes', mixin, { '~dummy-hook': function() { alert('This is called for every bike'); } }; // or at instance level: var myBike = Bike.$build(); myBike.$on('dummy-hook', function() { alert('This is called for myBike only'); }); // or event at decorated context level myBike.$decorate({ 'dummy-hook': function() { alert('This is called for myBike only inside the decorated context'); } }, fuction() { // decorated context });

-
$dispatcher() → {function}
-
Retrieves the current object's event dispatcher function.
This method can be used in conjuction with
$decorate
to provide a consistent hook context during async operations. This is important when building extensions that want to support the contextual hook system in asynchronic operations.For more information aboout contextual hooks, see the CommonApi#decorate documentation.
Usage:
restmod.mixin({ $saveAndTrack: function() { var dsp = this.$dispatcher(), // capture the current dispatcher function. self = this; this.$save().$then(function() { this.$send({ path: '/traces', data: 'ble' }, function() { this.$decorate(dsp, function() { // the event is dispatched using the dispatcher function available when $saveAndTrack was called. this.$dispatch('trace-stored'); }); }); }); } })
