Hi, Folks!
I have an app that contains many lessons, which, in turn, contain many slides. I have a service (see below) that keeps track of how many slides each lesson has by introspecting the registry to see how many slide templates exist for that lesson. Is there a way to do this via a public API, instead of using __registry__.knownForType
?
# app/services/session.coffee
`import Ember from "ember";`
`const { getOwner } = Ember;`
Session = Ember.Service.extend
lessonNumber: 1
slides: ( ->
templates = getOwner(this).__registry__.knownForType("template")
templateNames = Object.keys(templates)
slideNames = templateNames.map (templateName) =>
match = templateName.match(new RegExp("slides/#{@lessonNumber}/(\\d+)$"))
match[1] if match
slideNames.filter (slideName) ->
Ember.isPresent(slideName)
).property()
Thanks for your time!
