why should I use 'plurals' in RESTAdapter

Question

According to ember-part-2,

We should define the the plurals for model ? why ?

MVC's feature is convention over than configuration,

Why should I do it, and for what ?

app/assets/javascripts/models/store.js.coffee

DS.RESTAdapter.configure("plurals", entry: "entries")

Answer 1

Normally, you don't need to do this. Ember has an Inflector that can handle most pluralization.

Ember.Inflector.inflector.pluralize('entry') === 'entries'

If it doesn't, you can add your own:

Ember.Inflector.inflector.irregular('formula', 'formulae');     
Ember.Inflector.inflector.uncountable('butter'); 

Ember Inflector is now a separate package and can be used outside of Ember: https://github.com/stefanpenner/ember-inflector
