get all task instances

[st-h]

I was trying to get all instances of a given task but could not find any method or property for doing so. I thought I could get that from the scheduler, but as soon as I created a computed property on _scheduler.activeTaskInstances I ended up with an error that I need to call set when trying to modify the activeTaskInstances. Not quite sure what is going on, but it's not part of the api anyways. Finally I ended up pushing any new task to a dedicated array, which seems to work just fine, but I was wondering if it might be a nice idea to expose the task instances so they could be easily referenced. Currently we only seem to be able to get the last instance. What do you think?

I've been looking for this too. I'd like to delete a bunch of records 1 by one, and show the status of each in the template.

deleteClassTask: task(function* (schoolClass) {
  yield schoolClass.destroyRecord()
}).enqueue(),

// returns something like { 5: instance, 6: instance, ... }
deleteClassInstances: computed('deleteClass.allInstances.[]', function () {
  const instances = this.deleteClassTask.allInstances // this could be handy
  return instances.reduce((acc, instance) => {
    const classId = instance.args[0].id // not sure if args is public api or not
    return { ...acc, [classId]: instance }
  }, {})
}),

actions: {
  deleteClasses() { selectedClasses.forEach((c) => this.deleteClassTask.perform(c))
},

{{#each selectedClasses as |class| }}
  {{#let (get deleteClassInstances class.id) as |deletionInstance|}}
    {{class.name}} {{if deletionInstance.isRunning "deleting" "queued"}}
  {{/let}}
{{/each}}

(this code isn't perfect, just a rough idea of what could be done if task.allInstances was a thing). It may very well be better to just keep track of a separate property of performed instances separately and insert into it for each perform call
