JavaScript Models for podjs compliant datastores.

BLOXX Models are not part of any larger MVC framework. Just plain JavaScript data structures with a built in persistence API. Designed to work in both the Browser (IE9+) and Node.js.

API

#fetch(options)

Fetches an object from the datastore. The difference from #load is that #fetch() will return null instead of raising an exception if the object cannot be found in the store.

Returns a resolved Promise for a new instance of the same model type. If the object cannot be found, the returned promise will resolve to null.

The options object will be passed through to the underlying store.

Character.create({id: 'spider-man'})
  .fetch()
  .then(function (character) {
    console.log(character.name); // 'Spider Man'
  });

Character.create({id: 'foobar'})
  .fetch()
  .then(function (character) {
    console.log(character === null); // true
  });

#load(options)

Loads an object from the datastore. The difference from #fetch is that #load() will return a rejected Promise instead of null if the object cannot be found in the store.

Returns a resolved Promise for a new instance of the same model type. If the object cannot be found, #load() will return a rejected promise with error code "NOT_FOUND".

The options object will be passed through to the underlying store.

Character.create({id: 'spider-man'})
  .fetch()
  .then(function (character) {
    console.log(character.name); // 'Spider Man'
  });

Character.create({id: 'foobar'})
  .fetch()
  .catch(function (err) {
    console.log(err.code); // 'NOT_FOUND'
  });

#loadHasMany(options)

Fetches related objects from the datstore and loads them into the #hasMany property.

If an options.include Array is present #loadHasMany will only query for the types listed in options.include. If options.include is not present, then #loadHasMany will query for all the hasMany types configured for the Model class.

Series.create({id: 'spectacular-spider-man'})
  .loadHasMany({include: ['Character']})
  .then(function (characters) {
    console.log(characters[0].id); // 'spider-man'
    console.log(characters[0].type); // 'Character'
    console.log(characters[0].name); // 'Spider Man'
  });

#loadBelongsTo(options)

Fetches related objects from the datastore and loads them into the #blongsTo property.

If an options.include Array is present #loadBelongsTo will only query for the types listed in options.include. If options.include is not present, then #loadBelongsTo will query for all the belongsTo types configured for the Model class.

Series.create({id: 'spider-man'})
  .loadBelongsTo({include: ['Series']})
  .then(function (series) {
    console.log(series[0].id); // 'spectacular-spider-man'
    console.log(series[0].type); // 'Series'
    console.log(series[0].title); // 'The Spectacular Spider Man'
  });

#fetchHasMany(options)

Fetches related object IDs from the datastore. The difference from #loadHasMany is that #fetchHasMany() does not hydrate the attributes of the objects, it only returns the base Objects {id: "STRING", type: "STRING"}.

If an options.include Array is present #fetchHasMany will only query for the types listed in options.include. If options.include is not present, then #fetchHasMany will query for all the hasMany types configured for the Model class.

Returns a Promise which resolves to an Array of base Objects. If none are found, the Array will be empty.

Series.create({id: 'spectacular-spider-man'})
  .fetchHasMany({include: ['Character']})
  .then(function (characters) {
    console.log(characters[0].id); // 'spider-man'
    console.log(characters[0].type); // 'Character'
  });

#fetchBelongsTo(options)

Fetches parent object IDs from the datastore. The difference from #loadBelongsTo is that #fetchBelongsTo() does not hydrate the attributes of the objects, it only returns the base Objects {id: "STRING", type: "STRING"}.

If an options.include Array is present #fetchBelongsTo will only query for the types listed in options.include. If options.include is not present, then #fetchBelongsTo will query for all the blongsTo types configured for the Model class.
