createRecord之后如何检测Ember.js中的关系更改

Question

I have

Ember.computed("task.inputValues.[]", ..

Inside this method at certain condition, i trigger creation of new inputValues that have a task set with belongsTo . But after records and relations are successfully set in Ember database (using " createRecord "), " task.inputValues.[] " does not catch/trigger computed method to recalculate?

Answer 1

As Acorncom mentioned " folks recommend avoiding computed properties with side effects (such as creating new records) "

Seems there is some kind of protection in Ember that prohibits recursive triggering of computed property by itself.

The solution was to move records creating code from computed property to Observer, after new records got inserted by the observer, computed property selector "task.inputValues.[]" did trigger.
