ember.js - How to use the hooks offered by Ember Data -


i trying utilize hooks commented on through ember data source code, can't seem implement methods in way called.

i trying use keyforpolymorphictype hook in ds.jsonserializer, a hook can use in serializer subclass customize how polymorphic association's name converted key type. , here how have set up

var jsonserializer = ds.jsonserializer.extend({   keyforpolymorphictype: function(name) {     debugger   } }) var serializer = jsonserializer.create()  ds.restadapter.configure('serverdemo.component', {   alias: 'component' });  serverdemo.adapter = ds.restadapter.extend({   bulkcommit: false   ,serializer: serializer });   serverdemo.store = ds.store.extend({   revision: 12,   adapter:  serverdemo.adapter.create() });

if offer guidance on how use hooks sprinkled throughout source, helpful

edit

here models

serverdemo.note = ds.model.extend   title: ds.attr 'string'   content: ds.attr 'string'   index: ds.attr 'number'   noteable: ds.belongsto 'serverdemo.noteable'  serverdemo.noteable = ds.model.extend   note_ids: ds.hasmany 'serverdemo.note'  serverdemo.part = serverdemo.noteable.extend   rack_pos: ds.attr 'number'   server_config_id: ds.belongsto 'serverdemo.serverconfig'   partable: ds.belongsto 'serverdemo.partable', { polymorphic: true }   note_ids: ds.hasmany 'serverdemo.note'   semanticrackpos: (->     "rack_pos_#{this.get('rack_pos')}"   ).property('rack_pos')  serverdemo.partable = ds.model.extend   part_ids: ds.hasmany 'serverdemo.part'  serverdemo.component = serverdemo.partable.extend   back_image: ds.attr 'string'   cols: ds.attr 'number'   rows: ds.attr 'number'   front_image: ds.attr 'string'   name: ds.attr 'string'

you're on right track. suggest inherit ds.restserializer instead of ds.jsonserializer.

my guess testing code against models don't implement correctly polymorphic association.

take @ test: https://github.com/emberjs/data/blob/master/packages/ember-data/tests/integration/belongs_to_test.js#l119

at top of file, can see how store, adapter, serializer , models set up.

update (after describe models).

one thing pay attention to, rest serializer camelize/decamelize attributes. not doing it. (server_config_id -> serverconfig)

attributes associations have name describes model, not attribute id in json (note_ids -> notes)

you have working that:

serverdemo.note = ds.model.extend   title: ds.attr 'string'   content: ds.attr 'string'   index: ds.attr 'number'   noteable: ds.belongsto 'serverdemo.noteable', {polymorphic: true}  serverdemo.noteable = ds.model.extend   notes: ds.hasmany 'serverdemo.note'  serverdemo.part = serverdemo.noteable.extend   rack_pos: ds.attr 'number'   serverconfig: ds.belongsto 'serverdemo.serverconfig'   partable: ds.belongsto 'serverdemo.partable', {polymorphic: true}   semanticrackpos: (->     "rack_pos_#{this.get('rack_pos')}"   ).property('rack_pos')  serverdemo.partable = ds.model.extend   parts: ds.hasmany 'serverdemo.part'  serverdemo.component = serverdemo.partable.extend   back_image: ds.attr 'string'   cols: ds.attr 'number'   rows: ds.attr 'number'   front_image: ds.attr 'string'   name: ds.attr 'string'

it unclear me if design looking there no need polymorphic associations. reduce number of models define.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
