'Ember JS check if the model is already defined
Trying to define custom model in ember using
Ember.getOwner(this.store).register('model:custom-model', {
customName: DS.attr('string')
});
While running the same component again, getting the following error saying the model is already defined.
Uncaught (in promise) Error: Assertion Failed: Cannot re-register: 'model:custom-model', as it has already been resolved.
How to check if the model is already defined?
Solution 1:[1]
There is the hasRegistration() method which should help you, i.e.
if (Ember.getOwner(this.store).hasRegistration('model:custom-model')) {...}
One thing though - you're using quite old version of Ember, so this answer might require some refinement, however this method exists at least in v2.18.
