I created a computed property to concat two model properties together, and create a list of them. It initially worked like this, which results in a list like so: prop1-prop2, prop1-prop2
modelName: Ember.computed(
return this.get('modelName').map((o) => {
return o.get('prop1') + '-' + o.get('prop2');
}).join(', ');
})
Then I changed it to this which results in the same list:
modelName: Ember.computed(
return this.get('modelName').map((o, i) => {
return (i > 0 ? ' ' : '') + o.get('prop1') + '-' + o.get('prop2');
});
})
My question is, where is the second computed property getting the comma to put in the comma-separated list? The initial code I tried was (i > 0 ? ', ' : '') but that was adding two commas. Can anyone explain?
You forgot to return the result.
modelName: Ember.computed('modelName',
return this.get('modelName').map((o, i) => {
return (i > 0 ? ' ' : '') + o.get('prop1') + '-' + o.get('prop2');
});
})
and also I will encourage you to have dependant key modelName
